pairs to the very minute brown pollen-carriers by very short 
caudicles. Follicles narrowly fusiform, acuminate, smooth, glabrous. 
Succulent leafless herbs; stems tufted, usually procumbent and often with 
their tips or other portions buried in the ground, in one species sometimes 
(always ?) flowering underground, acutely, obtusely or obscurely 4-8-angled, 
acutely toothed or tessellately tuberculate along the angles, often with a distinct bud 
in the axil of each tooth or tubercle when the stems are fully developed ; flowers 
small, solitary or in fascicles in the grooves or on the sides between the angles, 
small, bud-like, often with a ‘‘frosted” appearance on the inner surface and 
sometimes outside as well. The colour of tie flower is taken from Mr, Pillans’ 
notes, except in the case of P. asperiflora.
