deeply cleft wings, and longer calyx tube. It is a little 
more robust and with larger flowers, but I have speci- 
mens from the Buckskin Mountains, Northern Arizona, on the 
border of Utah, with the calyx lobes one-half as long as the 
tube, and not deeply cleft wings. My specimens of 4. scaposus, 
named by Dr. Gray himself, show a great diversity in the lobing 
of the wings. Specimens from Southeastern Utah, collected by 
Miss Eastwood, have a short calyx and short teeth, but are 
otherwise as in 4. calycosus. I have given a full description of 
A. calycosus in ‘‘ Contributions No. 3,’’ so that it is not necessary 
to repeat the character of the pod, which differs in no respect, 
when fully developed, from A. scaposus.. I have compared the 
type of Mr. Greene’s 4. candicans and find that it differs in no 
respect from A, scaposus. 
Astragalus Hosackie, Greene, Bull. Cal. Acad. i, 157. This 
is acommon form of 4. humistratus. Ihave plenty of specimens, 
gathered along with the usual form of 4. humistratus, that have 
the pod of 4. Hosackie and the general form of the leaves of 
A. humistratus. I have others with the leaves and general 
aspect of 4. Hosackiz. Mr. Greene’s species seems to grow in 
‘the shade, where the leaves become wider. ‘The pod of A. 
humistratus varies greatly, being curved to a half circle or nearly 
straight and short; it is also a little sulcate dorsally often. The 
crowding of the leaflets and leaves is of common occurrence. 
Astragalus Gilensts Greene, Torrey Bull. viii, 97. This is 
a very distinct and interesting plant, but belongs to the Homa- 
lobi. ‘The keel is incurved and sharply acute, one-half a line 
shorter than the wings, banner one to one and one-half lines 
longer than wings, the keel exceeds the calyx teeth by a line 
only; calyx tube one and one-half lines long, narrowly campanu- 
late equaling the subulate teeth; bracts hyaline, acuminate, 
lanceolate, one and one-half lines long, longer than the short 
pedicel; calyx contracted at base; flowers in a head which is one- 
half an inch long; pod flattened laterally, about two-seeded, 
obliquely ovate-oblong, one-celled, no intrusion of sutures, thin- 
chartaceous, dorsal suture about straight, ventral much arched, 
the pod seems to be wrong side up but it is not so, sharp pointed,
