It has been suggested that Hosackia wrightii Gray (Lotus wrightii 

 Greene) is too near H. puheruJa Benth. (L. j^uberulus Greene), to be 

 a distinct species; but if my assumption, that the specimens in the 

 Herbarium of the U.S. National Museum from Mexico cited below are 

 typical L. puherulus Greene, be correct, the two are clearly dis- 

 tinct. The leaves of L. puherulus Greene are not in the least sub- 

 palmate but are strictly pinnate with 4 to 8 (3) acute linear leaflets. 

 The majority of the plants in the U.S. National Herbarium, from 

 Arizona and New Mexico have subpalmate leaves and seem more 

 closely akin to L. wrightii Greene than to L. puherulus Greene. The 

 Mexican plants cited below are assumed to be typical of Hosackia 

 puherula Benth., since Bentliam's type of H. puheruJa came from 

 near Zacatecas. Mexico. The plants listed herewith are clearly L. 

 puherulus Greene not L. wrightii Greene. — Mexico: in the Sierra

Var. multicaulis Ottley n. var. (pi. 70, figs. 7-13). Decumbent or 

 ascending, with many stems arising from a perennial root; leaflets

 those of the species and those of L. rigidus Greene; pods 2 to 2.5 cm. 

 long, 2 to 2.5 mm. wide.
