petioled tips that are
acuminate; the base is rounded, opaque, leathery above and sparsely beneath; the central nerves protrude thickly beneath; there are two very fine nerves on either side that send loose spikes above the base; the petiole is hairy. The terminal leaves are somewhat larger than the leaves, and the petioles are equal to the
peduncles, which are sporadically hairy. Orbicular
bracts sub-
sessile at the centre. At the centre of the stigmatic centrum, at the tip of the scutellum sursun pointed amata, a cylindrical pale berry openedly appeared. Simple ceraceous stem with simple hairs that are 0.005 thick and very densely hairy.
Limb length: 0.065; width: 0.035. Petiole length: 0.015 in.
Berry length is 0.003 in. ==Taxonomy and naming==
