228 LEAFLETs. 
G. RIGIDA. Greene, under Zhelypodium. 
G. INALIENA. Robinson, “ £ 
G. ROSTRATA. Watson, “ Arabis. 
G. COOPERI. S “ ` Thelypodium. 
Despite its likeness to G. rostrata, and its desert habitat, the 
flowers in this are subsessile, the calyx closed, the petals with 
clear distinction of blade and claw. It is possibly a monotype. 
G. FLAVESCENS. Torrey, under Streptanthus. 
G. HOOKERI. Streptanthus flavescens, Hook. 
S..campestris, Wats., by the specimens, as also by the original 
description, was a sorry medley from the very outset. By the 
specific name the plant from Campo must be received as the 
type. The material of that is fragmentary; but its calyx her- 
baceous, purple, the sepals all alike and exact, not spreading. 
It may well hold its place and name under Streptanthus until 
better known. 
The plant of the San Bernardino Mountains mixed with the 
above in books and lists is exceedingly remote from it in both 
habit and character, and can not be consistently admitted into 
any of my streptanthoid segregate genera. I name it in the 
type of a new genus, 
AGIANTHUS, Calyx almost that of Huclisia, nearly as irreg- 
ular, its sepals thin, whitish, translucent, also loosely investing 
the Euclisia-like petals, stamens, etc., but the whole calyx re- 
markably short, each sepal broad and blunt at summit. Pods 
large, narrow, more or less tortuous. Plants all perennial, in 
foliage altogether much like Cartiera. Specimens of two species 
are before me. 
A. BERNARDINUS. Basal leaves cuneate-obovate to spatulate- 
oblong, rather obscurely dentate mostly at and near the summit: 
pods very narrow, almost 4 inches long, spreading or even re- 
curved and tortuous.—San Bernardino Mountains, Parish ; also 
San Jacinto Mountain, H. M. Hall. both as Streptanthus cam- 
pestris.
