Herba succulenta, parce ramosa, usque ad 50 em alta, in sicci- 
tate pallide flavido-viridis, ramis parce ciliatis; foliis chartaceis,.

ciliatis; nervis utrinque 4 ad 6, supra impressis, subtus valde 
perspicuis; stipulis anguste lanceolatis, circiter 1 cm longis;

An erect, sparingly branched, succulent herb, about 50 cm 
high, pale greenish yellow when dry, the stem glabrous with 
numerous cystoliths, the branches with scattered, spreading, elon- 
gated, weak, white hairs. Leaves chartaceous when dry, some- 
what inequilateral, oblanceolate, 6 to 11 cm long, 2 to 3 cm wide, 
the apex slenderly acuminate, the base somewhat inequilateral, 
acute on the narrower side, obtuse on the broader side, the mar- 
gins rather conspicuously serrate except near the base, the upper 
surface with numerous cystoliths, scabrous, the younger leaves. 
with numerous, spreading, elongated, weak hairs from swollen 
bases, the swollen bases persisting on the older leaves causing 
the surface to be distinctly scabrous, the lower surface of the 
Same color as the upper with equally distinct cystoliths, the 
midrib and nerves with scattered, conspicuous, spreading, white 
hairs ; lateral nerves 4 to 6 on each side of the midrib, impressed 
on the upper surface, very prominent on the lower surface,

illary, sessile, 5 to 10 'mm in diameter, flattened, irregular, the 
bracts connate, forming an irregularly lobed receptacle about 6
