184 Rydberg: Notes on Fabaceae — I 



The type came from Thompson 's Springs, Utah. The decidedly 

 oblique pods and black-hairy calyx of //. Dodgeanus would 

 make the species distinct enough, if these features should prove 

 constant; otherwise the two species should perhaps be united. 

 In this case Jones's specific name should be retained. 



14. Homalobus Clementis Rydb. See my notes under 

 H. Standleyi above. Notwithstanding Macbride's remarks and 

 his reduction of this species to a variety of Astragalus tenellus, 

 I still consider it nearest to //. wingatanus and worthy of recogni- 

 tion. In both //. wingatanus and the allied H. lancearius the 

 pod is acute at each end, as in H. Clementis, and a minute stipe 

 is sometimes produced. In //. lancearius, in fact, this stipe 

 may be fully as long as in H. Clementis. The following speci- 

 mens may be cited: — 



Colorado: Saugre de Cristo, Clements; Marshall Pass, 

 Baker 489; without locality, C. H. Hall. 



15. Homalobus wingatanus (S. Wats.) Rydb. To the 

 specimens listed by Macbride the following may be added: — 



Colorado: Mancus, Eastwood. 



Utah: Monticello, Rydberg & Garrett 915 1, 9228. 



16. Homalobus lancearius (A. Gray) Rydb. This species 

 is still known with certainty only from the type collection: 

 Beaver Dam, Arizona, 1877, Palmer 114. A flowering specimen 

 from Allen Canyon in southeastern Utah, Rydberg & Garrett 

 9309, resembles the type very much but is doubtful in the 

 absence of fruit. In the original description of Astragalus 

 lancearius, Gray called attention to the fact that the species 

 strongly resembled A.filipes in habit and in flowers, but that the 

 pod was perfectly sessile. On this account it would have to 

 be placed in the Tenelli group, probably near H. wingatanus 

 and H. acerbus. Jones* claimed that the species was the same 

 as Astragalus recurvus Greene, which on account of its completely 

 two-celled fruit is a species of Hamosa. Later hef retracted his 

 statement, adding that A. lancearius was "a good species but 

 near A. Rusbyi Greene." The first part of his conclusion is 

 correct but the latter part is far from the mark. 



17. Homalobus episcopus (S. Wats.) Rydb. Under Astrag- 

 alus Coltoni Jones, Macbride makes the following statement: 



* Proc. Calif. Acad. II. 5: 636. 1895. 

 t Contr. West. Bot. 8: 12. 1898.
