We have ventured to found this species on very imperfect materials, on account of 
its distinct character. It is readily distinguished by its glabrous glaucous stems and 
rather large Jeaves in whorls of seven, associated with loose inflorescence, thread-like 
pedicels, and a naked somewhat fleshy fruit.
