4. A. FIMBRIATUS Benth. Wats. Bot. Calif. 2: 42. 1880. 
Easily known by the broad fimbriate often beautifully 
colored sepals.—Reported abundantly from southern an 
eastern California, Nevada and southern Utah, western Texas, 
Arizona, New Mexico, southward into Mexico and Lower 
California. 
«Var. DENTICULATUS (Torr. ). 
A, venulosus Wats. Proc. Amer. Acad. 17: 376. 1882. 
Sarratia Berlandieri var. denticulata Torr. Bot. Mex. Bound. 179. 1858. 
This is not dicecious as Watson described it, but agrees 
with A. fimbriatus except that the broadly dilated lamina of 
the sepals is not fimbriate, but entire or emarginate, and con- 
spicuously marked by branching green veins. 
5. A. PRINGLEI Wats. Proc. Amer. Acad. 21: 476. 1886. 
Known from A. fimbriatus by the more scattered axillary 
inflorescence, distinct sepals with green mid-rib, broad scar- 
ious margin not fimbriate, longer acute outer sepal and longer 
spiny bracts. 
Probably has much the same range as A. fimbriatus, but 1s not re- 
ported from so many stations, nor in so great abundance. 
6. A. SQUARRULOSUS (Gray). 
Ambloygne squarrulosa Gr. Proc. Am. Acad. 5: 168. 1861. 
Scleropus sqguarrulosus. Anderss. ined. 
A species from the Galapagos Islands, with the beet 
ovate or rhombic-ovate lamina of the female sepals 4 
abruptly contracted into a narrow claw, peduncles an 
pedicels thickened, as in A. crassipes. Plant tall and slender, 
resembling A. fimbriatus.
