CONTRIBUTIONS TO WESTERN BOTANY 45 
hroughout the plant and nearly sessile, 1-2 inches long, broad, 
with about 10 flowers subtended by relatively, large, green but 
ciliate bracts, Calyx white, loosely inclosing the floral parts as 
if inflated, obliquely cylindrical from a triangular base which has 
1-2 bractlets at the oblique insertion, the tube a little arcuate be- 
cause the lower side is concave and upper mvch arched, about 4 
mm. long by 2-3 mm. wide and laterally flattened, the subulate 
teeth lax and about 2mm.long. Banner narrow and much arched 
and with reflexed sides. Wings straight, narrow and a little lon- 
ger than the keel.and often purple-tinged at tip. Keel very blunt 
und purple-tipped. Pods as ashy-puberulent as the leaves, slight- 
ly arched and shortly acute, about 2 mm. highand 6-8 mm. long, 
deltoid in cross-section and deeply sulcate dorsally to the middle, 
und with a complete hyaline partition to the ventral suture which 
is raised exter ally as a strong rib, smooth, sessile. Whole plant 
a mass of flowers. Named for Mrs. Mexia the collector. 
Astragalus Coquimbensis (H. & A.) ReicheVol. 2p 109 FI. 
Chil. seems to be the same as A. Thurberi Gray and antedates it. 
A, candidissimus Ledebour is not the same as Watson’s synonym 
which fact justified Greere’s A. Miguelensis. 
A, Crotalarie Bth,, A. limatus Sheldon was described as from 
Monterey by Coulter and led to much confusion by Gray, but it 
could not have come from there. 
+mosa manca Rydberg is A. Austine Gray as shown by the con- 
nate stipules. 
Xvlophacos lagopina Rydberg seems to be A. Pulsifere Gray 
A. Breweri Gray and filicaulis F, & M. are related,but not identi- 
Cul, 
A Laxmanni Jacq. has been assumed to be the same as ad- 
surzens Pall. and our nitidus but this cannot be for the pubecence 
is not fixed by the middle as in nitidus, 
A. Mauretanicus Stev. and Parryi Gray seem related. 
A, Mexicanus A. DC. seems to hold up onthe calyx being in- 
clined to be inflated and 6 mm. long, with deltoid teeth about 1 
mm, long, and the tube being white-short-shaggy with hairs in- 
clined to be felted, banner broad. 
A, obcordatus is to be compared with A. distortus, but it has 
no sign of a septum as is shown by distortus at times, This group 
the Sparsiflori should come either near the Hamosi or distortus 
put in the Hamosi. 
Hamosus Minthornie Rydberg is A. Congdoni Watson, prob- 
ably, but the locality of collection very doubtful. 
A. curtipes Gray és a very doubtful species of the Monterey, 
Cal. region, going up as far as San Francisco, and belongs in the 
puzzling leucopsis group and may be the same as A. Franciscanus 
Sheldon, a freak of leacopsis with connate stipules.
