apex, and pendulous; keel exceeding the calyx teeth by two 

 lines, wings one and one-half lines longer than keel, and banner 

 two lines longer than wings, banner erect, wings and keel 

 arched, broad tip of keel incurved at a right angle. Otherwise, 

 as in ^. collinus. Described from the type collected at Yreka, 

 Cal., by E. Iv. Greene. This differs from A. collinus {Phaca 

 colli?ia Hooker) as described in Flora of North America, T. & 

 G., 347, in the leaflets being closely set and not "remote," 

 shorter, peduncle longer, calyx not "tubular" nor "elongated" 

 but campanulate as a rule, and in the banner being much longer 

 than the elongated wings. It differs from the description given 

 in King's Rep., p. 444, in jthe "pod being linear and not linear- 

 oblong. Watson there gives the calyx as oblong-campanulate 

 or cylindric, and the pod as an inch long. Canby, in Botanical 

 Gazette, xii, 150, gives it as his opinion that this is only a 

 variety of A. collimis. No one seems to have remarked upon 

 the short keel and close set leaflets. If these are common to the 

 true A. collimis, then, no doubt, this is a form of A. collinus. 



Astragalus Mogollonicus, Greene, Torrey Bulletin viii, 97. 

 This is only a form of A. Bigelovii apparently, as it is a com- 

 mon thing for A. Bigelovii to be very hirsute with yellow hairs, 

 and the pod is from oval and short pointed to lanceolate and rather 

 long pointed. The immature pod of this plant is straight and cylin- 

 dric-lanceolate. Rusby's specimen is fully as large as A. Bige- 

 lovii and like it in all respects so far as can be seen, but it has no 

 mature fruit, while Greene's specimen, rhe type, is very young 

 and without fruit at all. I have a specimen of A. mollissimus 

 from the same region, the San Francisco Mountains, Ariz., that, 

 so far as the yellowness is concerned, would pass for A. Mogol- 

 lonicus were it not for the cylindrical and perfectly glabrous pods. 



Astragalus calycosus Torrey var. scaposus (Gray) A. scaposus 

 Gray, Proc. Am. Acad, xii, 55. A. opindicatis Greene, Bull. 

 Cal., Acad, i, 156. It is strange that Dr. Gray did not recog- 

 nize the close relationship of this plant with A. calycosus. It 

 has onlj'- the remotest resemblance to A. Missourie^isis and no 

 relationship to it. The true A. scaposus differs Irom A. calycosus- 

 only in the short and triangular calyx lobes and the less
