inner corona-lobes) on their inner face. Staminal column arising 
from the base of the corolla ; anthers suberect, oblong, without an 
appendage, but with two or more hairs at their tips. Pollen-masses 
erect, solitary in each anther-cell, with a small pellucid area imme- 
diately under the apex, attached in pairs to the pollen-carriers by 
very short slender caudicles. Fruit not seen. 
Perennial herbs; rootstock a cluster of thick fleshy roots ; stems several, 
prostrate ; leaves opposite, petiolate, cardate-ovate or cordate-orbicular, herbaceous ; 
flowers rather small, in pedunculate or sessile umbel-like cymes. 
DistriB. Species 2, endemic. 
The coronal structure of this genus is scarcely distinguishable from that of those 
species of Brachystelma (such as B. schizoglossoides, N. E. Br., B. mafekingense, 
N. E. Br., etc.), where the halves of the divided outer corona-lobes are connate 
with the halves of adjacent lobes immediately behind and partly adnate to the 
base of the inner corona-lobes, but the habit and general appearance 1s quite 
different from that of any species of Brachystelma.
