SPECIES DESCRIPTION:
Translated from protologue: Climbing. Stipules subopposite. Petiole glabrous; blade cordate-ovate, with the thicker veins exposed in the sinus, the anterior-lobe veins 4–6, without secondary veins, the veinlets fine. Known only from a young plant: petiole terete, one-third longer than the midrib; blade equal-sided, oval, rather deeply cordate with a narrow sinus, the posterior lobes somewhat overlapping, obliquely semi-oval, with 4 veins to the anterior lobe.
INFLORESCENCE:
Translated from protologue: Peduncles several from a single axil. Spathe thick, gibbous, its blade boat-shaped, nearly shorter than the stout spadix.
ETYMOLOGY:
Although the protologue does not explain the name, the epithet is from Latin consanguineus, “of the same blood” or “closely akin,” and likely alludes to this species’ close resemblance to its neighboring congeners in Schott’s grex Cardiobelium.
NOTES:
1. Schott placed Philodendron consanguineum in his grex Cardiobelium (Synopsis Aroidearum, 1856), a group of climbing species with subopposite stipules and cordate-ovate blades; the original diagnosis notes that it was based on a young (juvenile) plant.
