ternate leaves, with Hlaodendron, Jacq. f., in which the leaves are 
usually opposite ; there seems no floral or carpical differences between 
them. The present species is readily known by its very copious and 
softly velvety pubescence, and its much branched inflorescence.

Dzscr.— Parasitic on roots. Stem, or rhizome, horizontal and ge- _ 
nerally underground, irregularly branching, from 3-1 inch thick, — 
4-sided, with rows of blunt, wartlike tubercles or prominences on the 
angles, coated with a brown skin, solid, fleshy. Flowers arising on the 
angles of the stem, as if from the enlargement of a tubercle, erect, 
scarcely-stipitate. Perianth fleshy, brown, coated externally with 
scurf-like scales which rub off, with a cylindrical tube 3-4 inches long 
and 1-1} diam., expanding at the summit into a 38—-lobed limb; the 
lobes very broad, remaining persistently soldered together in their upper 
half, but separating and gaping in the lower, the gaping margin slightly 
inflexed, entire (not ciliate). Column of stamens near the summit of 
the tube, 3-lobed, the lobes blunt, opposite the segments of the perianth. 
Anthers indefinite, linear, parallel, adnate to the fleshy column, extrorse. 
Ovary adnate with the base of the perianth. Stigma sessile, flat, some- 
what 3-lobed. Placenta indefinitely numerous, cylindrical, pendulous 
from the root of the ovarian cavity, each covered with very many cellu- 
lar ovules. s 
I am indebted to the Rev. 7. Whitehead, now of St. Helena, forthe _ 
fine specimen of this curious plant, preserved in spirits, from which our 
figure has been taken.
