ALOCASIA FALLAX
SYNONYMS: N/A
DISTRIBUTION: Assam, Bangladesh, East Himalaya (Sikkim Himalaya and Khasia Hills)
CLIMATE: Subtropical humid climate
Humidity is moderate throughout the year, ranging from 60% to 70%
Temperature is varies between the seasons - within the range of 48°F/9°C to 88°F/31°C during the day. Minimum temperatures never dip below 45°F/7°C
Rainy and humid season (October to May) and a dry season between June and October. The average annual rainfall is 1,200 mm
ECOLOGY: Found at alt. 2-4000 ft
SPECIES DESCRIPTION:
Leaves broadly ovate or orbicular-ovate sagittate (12-20 in by 9-12 in)m basal lobes (4-8 in), one-third as long as the anticous connate from 1/8-1/2 their length converging sinus narrow. Nerves numerous, 7-9 pairs; petiole 1-2 ft.
INFLORESCENCE:
Peduncle 18 in. Spathe 5-6 in., membranous, yellow; fruiting tube 2-2.5, ellipsoid or pyriform. Seeds 1/4 in. diam., globose. tube of spathe oblong lanceolate cuspidate limb, ovaries narrowed into a rather long style, stigma 3-cleft. Near A. decipiens, but seeds larger, and stigma very different, basal lobes of many-nerved leaves approximate. It is probably nearer A. fornicata.
VARIEGATED FORMS: N/A
ETYMOLOGY: The name comes from the latin word fallax, which means deceptive
NOTES: The chromosome number of Alocasia fallax is 2n = 28, with 24 metacentric and 4 submetacentric chromosomes, counted in material of the species maintained in the garden of the Bangladesh National Herbarium. Plant and cell numbers are not stated, and the authors give the count as probably the first report for the species.⁴
