15- Hamosa ensiformis (M. E. Jones) Rydberg. Astragalus
ensiformis M. E. Jones, Proc. Galif. Acad. II. 5: 658. 1895.
Though I have placed this species next to H. drepanoloba and
H. Paysonii, it is not closely related to either, differing in the
firm pod and leaves, the low habit and the large scarious stipules.
The corolla is unknown. Jones first described it under Astragalus
ursinus, stating that the ‘flowers seem to be identical with those
of anetinus, but paler.’ The type sheet, now at Pomona
College, has no flowers. It is known only from the tyne q$lla%-
tion from Pagumpa, Ariz., Jones 50950)1.
