ARACEAE · THE GENUS

DESCRIPTION

Scindapsus is a genus of 35 accepted species of root-climbing lianes, perching epiphytes and a few rock-creeping herbs in the family Araceae, native from the eastern Himalaya and Bangladesh through Indo-China and the whole Malay Archipelago to New Guinea, the Solomon Islands and the Queensland coast, with one species on the islands of Chuuk in Micronesia. It belongs to the tribe Monstereae, the climbers' tribe of the Old World that also holds Rhaphidophora, Epipremnum, Amydrium and Anadendrum, with the American Monstera nested among them, and it is told from its look-alikes by the fruit: each ovary holds a single ovule on a basal placenta and ripens one large kidney-shaped seed, where Rhaphidophora packs many small seeds into every berry and Epipremnum a few. Two of those numbers need saying plainly. The Kew checklist stands at 36; this site accepts 35, because Hay and Yuzammi showed in 2000 that Scindapsus rupestris, described from limestone at Bau in Sarawak in 1905, is the same plant as the older Scindapsus sumatranus, and where a published revision and a checklist disagree the revision is followed here. The range map counts 34, one fewer again, because Scindapsus grandifolius, described in 1898 from a plant in the Bogor garden, has no known wild range and sits on no map.

The plant on the windowsill is the shingling juvenile of Scindapsus pictus, sold everywhere under the name satin pothos, a misnomer that has sadly spread through the whole hobby, although the plant has nothing to do with the true genus Pothos. It is a stage the species keeps for years pressed flat to the bark while it climbs; the adult, rarely seen, hangs in curtains of branched stems from the tops of tall trees. That double life runs through the genus. Most species are diffuse climbers on small trees and rock faces that seldom pass 5 m; a few, such as Scindapsus altissimus of New Guinea, are huge, few-stemmed lianes that reach the canopy of emergent trees and commonly exceed 60 m; the species of the Bornean Coriaceus Complex are almost shrubs, sprawling over sunlit kerangas ridges on thick leathery leaves, and those of the Beccarii Complex perch in trees with their leaves held in a fan that traps falling litter. No one has revised the genus since Engler and Krause in 1908, and the botanists who know it best put its real size at perhaps 60 species, about half of them still without a name. The name is Greek: skindapsos, an ancient word for a plant resembling ivy.

Coriaceus Complex scandent shrubs of exposed kerangas; thick leathery blades, obscure veins, tough spathe
Beccarii Complex perching, litter-trapping epiphytes and lithophytes

The genus has no sections. Engler and Krause's key of 1908 divided it first on the stigma, orbicular and sometimes raised against oblong or linear and sunken. Within the orbicular-stigma group it then used how far the petiole is sheathed; within the oblong or linear group it used lateral-vein pattern, while Scindapsus coriaceus stands apart. What the modern literature offers instead are two informal complexes named from Borneo. The Coriaceus Complex, seven named species and more unnamed, is defined by thickly leathery blades with the venation all but invisible, smooth stems, a semi-terrestrial to scandent habit that climbs only a little, a preference for exposed kerangas, and solitary inflorescences in a thick leathery spathe; only Scindapsus scortechinii of Peninsular Malaysia and southern Thailand occurs outside Borneo. The Beccarii Complex holds the perching epiphytes that trap litter in a fan of large leaves. Beyond them the genus splits informally by habit into the diffuse climbers, which are most of it, and the huge canopy lianes, and Scindapsus pictus and Scindapsus lucens stand apart from the rest on their leaves alone.

Satin pothos and silver pothos are wrong names, and sadly the most widely used ones in the hobby: the plant has nothing to do with the true genus Pothos. The mistake is borrowed twice over. The trade kept the nineteenth-century garden name under which the silver-spotted juvenile was first sold, Pothos argyraeus, and the golden pothos it is likened to is not a Pothos either but an Epipremnum. The Thai names, the Hindustani one and the Chuukese one are the vernaculars recorded in the floras, the 1908 monograph and Hosokawa's paper describing the Micronesian species.

ARACEAE · RANGE

DISTRIBUTION

Wholly tropical and, but for one outpost, wholly Asian. The range begins in Nepal and the eastern Himalaya, Assam and Bangladesh, runs through Myanmar, Thailand, Laos, Cambodia and Vietnam to Hainan, reaches the Andaman and Nicobar islands in the Bay of Bengal, and takes in the whole Malay Archipelago from Sumatra and the Malay Peninsula through Borneo, Java, Sulawesi, the Philippines and the Moluccas to New Guinea. East of New Guinea it thins to the Solomon Islands and the Queensland coast, and to a single species on the islands of Chuuk, the only Scindapsus in Micronesia, found on a rocky sea-shore in 1936.

The center of the genus is Borneo, which holds 16 of the 34 mapped species, nine of them found nowhere else, and it is in Borneo that the unnamed species wait. Sumatra has 10, four of them endemic, Peninsular Malaysia 8, Java and Thailand 7 each, New Guinea 4, three of those endemic. Beyond Malesia the genus is carried by its few wide-ranging species: Scindapsus officinalis, the medicinal climber of India and Indo-China; Scindapsus hederaceus, from Indo-China through Sumatra, Java and Borneo to the Philippines; and Scindapsus maclurei, the giant of Hainan, Laos and Thailand. Kew records no introduced population anywhere. Scindapsus pictus, produced by the trade in tens of millions every year, has stayed in its pots.

ECOLOGY

CLIMATE

Scindapsus is a genus of the wet forest. Most species live in perhumid to everwet broadleaf forest at low to middle elevations, and the bulk of them below 1,000 m: in the lowland mixed dipterocarp and peat swamp forests of Sundaland, on limestone, on sandstone and on the raised podzols of the swamps. The genus is not confined to it. Scindapsus officinalis and Scindapsus hederaceus grow in the dry deciduous and dry evergreen forests of Thailand and Indo-China, Scindapsus maclurei in dry dipterocarp forest among rocks, and the shrubby species of the Coriaceus Complex on ridgetop kerangas that stands in full sun and goes nearly dry for part of every year. The elevational span runs from the sea-shore of Chuuk, where Scindapsus carolinensis climbs the trees above the rocks, to the open kerangas ridges around Mount Kinabalu, where Scindapsus kinabaluensis grows between 1,400 and 2,500 m; Scindapsus alpinus was collected at 1,800 m on Mount Merapi in Sumatra and Scindapsus scortechinii lives between about 1,000 and 1,600 m in the hills of Perak. Flowering has never been followed through a year in the wild; on Kinabalu it is seen mainly in plants fully exposed to the sun. The charts below draw the genus's measured envelope across its native range, and all 26 of its native places resolve in the climate data.

HABITAT

Nearly every species is a nomadic vine. It germinates on the forest floor, climbs the nearest trunk on clasping roots, and keeps feeding through roots that run down to the ground as it climbs, so that the base of the stem can rot away and the plant lives on, still rooted in the soil below. The juvenile presses its leaves flat to the bark, in many species in a shingle pattern and often silver-marked; the adult carries its leaves free, and in the largest species the flowering stems hang from the canopy. Many species send out flagelliform foraging shoots, long thin stems with reduced leaves that run along the ground or the trunk until they find a new support. The exceptions are the genus's most interesting plants. The Coriaceus Complex of Borneo climbs little or not at all: scandent shrubs of exposed kerangas, on an almost xerophytic footing for part of the year and in strong sun for part of every day, an ecology matched among aroids only by the lithophytic Anthurium of eastern Brazil. The Beccarii Complex perches in trees and on rocks with its leaves in a litter-trapping fan. Writing to the Aroid-L mailing list from Sarawak on February 8th, 2007, Peter Boyce named Scindapsus beccarii, Scindapsus crassipes and Scindapsus geniculatus, with a couple of undescribed species, among the obligate primary epiphytes there, plants that start on a tree and stay on it, whereas the nomadic vines start on the ground. All of them form fans of foliage that work as litter traps. Scindapsus rupestris creeps over limestone as a rheophyte, and Scindapsus lucens was found, after being described from greenhouses, in an abandoned rubber plantation on limestone and in shady peat forest. Every tissue is armed with needle-like trichosclereids, and in Scindapsus latifolius they are shed from the disintegrating leaf sheaths to bristle over the growing tip. Pollination has been observed once: the yeast-scented inflorescences of Scindapsus kinabaluensis fill with flea beetles and small scarabs, and its ripe infructescence sheds its stylar plates to expose pulp that smells of fermenting pineapple, presumably for whatever animal carries the single large seed away.

Araceae · Form

Morphology

A climber built like a Rhaphidophora and told from one only by its fruit, which ripens a single kidney-shaped seed where its neighbors ripen dozens. The plant on the windowsill is the shingling juvenile; the adult lives in the canopy.

A stem that runs in two gears: leafy zones that flower, and whips of long internodes and small leaves sent out to find the next tree. No milky sap; the defense is a needle-shaped cell.

The stem

Every Scindapsus is an evergreen climbing herb, and the range of size is the range of the genus. Most species are diffuse climbers on small trees and rock faces that seldom pass 5 m; a few are huge, few-stemmed lianes that climb the emergent trees of New Guinea and commonly exceed 60 m; the shrubby species of the Bornean kerangas hardly climb at all. The stem is terete and, in the climbers, runs from 3 to 4 mm thick in Scindapsus lucens to about 2.5 cm in Scindapsus maclurei, with the medium-sized species such as Scindapsus officinalis at 1.5 to 2 cm. Its surface is a character. The young stem is green and smooth; with age the epidermis of Scindapsus officinalis turns orange-brown and flakes, the older primary axis of Scindapsus pictus wears a conspicuous orange, brittle, scabrid skin, Scindapsus lucens is verrucate, its warts the same green as the stem, and the old stems of Scindapsus kinabaluensis go corky and crack into fissures, while the Coriaceus Complex as a whole keeps its stems smooth.

The architecture was worked out on Scindapsus lucens in cultivation. The main stem is sympodial and fertile: the shoot tip flowers, and only after it has flowered does a continuation shoot develop beside the inflorescence, so that the continuation looks terminal and the inflorescence looks lateral. Side branches are few and repeat the pattern, and the whole plant conforms to Chamberlain's architectural model. The genus is not uniform: Hay put Scindapsus altissimus, the commonest species in New Guinea, in Stone's model, with a non-flowering clinging axis that emits free lateral shoots bearing the inflorescences. On the stem the leaves may be evenly spaced, or the shoot may alternate between rosulate flowering zones with crowded leaves and stretches of long internodes with smaller leaves. Many species push that second habit to its limit as a flagelliform shoot, a whip of long internodes with reduced leaves that runs along the ground or the trunk until it meets a support and begins to climb, at which point ordinary leaves resume. The oldest plants of the genus, the perching epiphytes of the Beccarii Complex, do the opposite: they sit still on a bole and hold their leaves in a fan.

Roots and armor

The plant climbs on adhesive roots produced at the nodes, one or two per node in the slender species, that grow into the bark and hold. Feeding roots run down the trunk to the soil, and once they are established the base of the stem may rot away without harm; a climber begun on the ground finishes its life as a nomadic vine, still fed from below. The roots of Scindapsus lucens are 1 to 2 mm thick with a spongy epidermis. The epiphytic Scindapsus geniculatus roots differently from the climbers: Peter Boyce, writing to the Aroid-L mailing list from Sarawak on February 8th, 2007, described it as forming short, erect, pointed roots extensively into the litter that its fan of leaves collects, as many Anthurium do.

Cut a Scindapsus and nothing white runs out. The subfamily has no laticifers; what it has instead, in abundance, are trichosclereids, needle-shaped cells with pointed ends that lie in every tissue and are the reason the leaves and stems are unpleasant to chew. In Scindapsus latifolius of Borneo the leaf sheaths and cataphylls decompose into a persistent net of fibers that sheds its sclereids over the growing tip, so that the shoot bristles with stinging needles; it is the only species in which the character is so exposed.

01Evergreen climbing herbs from 5 m diffuse climbers to 60 m canopy lianes; stems 3 mm to 2.5 cm thick, terete, the surface smooth, flaking, scabrid, warty or corky by species.
02Sympodial: the tip flowers, then a continuation shoot develops beside the inflorescence; few side branches; Chamberlain's model in Scindapsus lucens, Stone's in Scindapsus altissimus.
03Leafy flowering zones alternate with long-internode zones; the flagelliform shoot is that habit run out as a whip to find the next support.
04Adhesive roots at the nodes, feeding roots to the ground; no latex, but abundant trichosclereids, exposed as a stinging fiber net in Scindapsus latifolius.

Cultivation

Scindapsus pictus is the one Scindapsus most people will ever grow, and it is grown as a permanent juvenile. Everything it wants follows from what a shingling climber does on a trunk in wet shade, and everything that goes wrong follows from a pot that is too wet or air that is too dry.

A hemiepiphyte in a pot: open, moisture-holding, never waterlogged, and something rough to climb.

In the wild the plant germinates in the litter of well-drained forest, climbs, and feeds through roots that run down the trunk to the ground while the rest of it lives in air against bark. A pot has to be the forest floor and the trunk at once. The mixes that serve are the ordinary open aroid mixes: a peat- or coir-based potting soil cut with bark and perlite so that water runs through and air follows it, kept moist rather than wet. The Missouri Botanical Garden grows Scindapsus pictus in a moist, well-drained mix on a moss stick; the trade's growers finish it in standard indoor potting mixes with good drainage; hobbyists root and grow it in long-fibered sphagnum. The plant is not fussy about the recipe, only about the drainage. The registrant of the cultivar 'Mayari' grows it in the ground in Sabah at a pH of 5.1 to 5.5, where it makes markedly larger leaves than in a pot, and that is the one measured number the genus has.

The support is part of the substrate. Clasping roots grow toward the dark and into whatever they touch, and a moss or coir pole kept damp gives them something to take that a bare cane does not; a Scindapsus pictus allowed to climb a damp pole produces larger leaves than one left to trail. The species of the Coriaceus Complex want the opposite treatment. They come from ridgetop kerangas on podzols and sandstone in full sun and near-drought for part of every year, and they need a lean, sharply drained mix and no coddling; Kartini and her colleagues note that they are easy to grow and almost never grown.
