Diagnostic
This species approaches Culcasia barombensis because of its often parallel primary veins, the deep nework translucent in the mesh of veinlets, the spathe constricted towards the base, the bilocular ovary; It differs by the acute base of the blade, decurrent on the petiole, the densely verrucose stem , the short peduncles, the exserted spadix, and the plants ability to flower at less than 2 m above the ground.
Distribution
This species is known only in Cameroon, in the Centre-South (Nanga Eboko, Obala, Ngoro, Evodoula, Yaoundé).
General Description
Plant climbing, reaching 1-2 m above the ground; Anchor roots short, ± numerous, 0.5 - 3 cm long; Stem densely and finely verrucose, rugose, 3-4 mm thick when dry; Internodes long, 1.5-5 cm. LEAVES: Petiole 7-13 (-16) cm, sheathed for 1/4 to 1/2 its length; Sheath broad; Blade 16-24 x 7-14 cm, oblong to oblong-ovate, ± assymetric, base slightly acute to obtuse, even subrounded with the blade clearly decurrent to 1.5 cm on the petiole, apex acute to acuminate, acumen 0.5-1 cm; 5-8 pairs of primary veins, prominent, arcuate ascending, finely doubling or tripling on departing the midrib, irregularly reunited with each other by attenuate secondary veins, forming with the tertiary veins, a dense, rather prominent network; Between the meshes of this network, a deeper translucent network, corresponding to the parenchyma with holes. On the lower surface of the blade, some sparse hydathodes and numerous glandular dashes orientated parallel with the edge of the blade, near the margin. INFLORESCENCES terminal, 2-3 rarely solitary; Peduncles short, 3-6 cm; Spathe 2-3 cm long, constricted towards the base, mucronate at apex, pale green to cream green; Spadix exserted, not stipitate; Male flowers yellowish; Female flowers pink or yellowish cream; Stigma circular, finely striate radially, ovary bilocular, each locule uniovulate; Ovule anatropous.
