As shown by Prof. Greene* the American genus Hosackia, of 

 Douglas, is not well separated from the Old World genus Lotus, of 

 Tournefort. In this list, therefore, the species are treated under 

 the latter name, that being the older of the two. 



Lotus crassifolius (Benth.) Greene, Pitt. ii. 147 (1890). 



Hosackia crass i folia Benth. 



Common along streams throughout the Lower Transition 

 Zone. (Nos. 826, 967.) 



Lotus glaber {Vogel) Greene, 1. e. 148. Syrniatinm gUibrum 



Vogel. Hosarl-ia glabra Torr. Deer- weed. 



Abundant in the chaparral belt, reaching the base of Chalk 

 Hill, and therefore confined to the Sonoran Zone. 



Lotus leucophaeus Greene, 1. c. 145. Hosackia grandiflora (?) 



anthylloides Gray. 



Also of the chaparral belt but somewhat rare and extending 

 well into the pine belt of the south and west sides, even to 6000 

 ft. alt. (Nos. 317, 557, 937, 2020.) 



Lotus Nevadensis (Wats.) Greene, 1. c. 149. Hosackia deciim- 



bens ffj Nevadensis Wats. 



Well distributed from the lower edge of the pine belt to 9000 

 ft. alt. Most common in open forests where the specimens are 

 provided with long internodes and broad leaflets. When grow- 

 ing in exposed places or at high altitudes the internodes are much 

 shorter and the leaflets not one-fourth as large. (Nos. 2337, 

 2379, 2491.) 



Lotus oblongifolius (Benth.) Greene, 1. c. 146. Hosackia oblong- 



i folia Benth. 



Of the same range as the last but not found above 8200 ft. 

 alt., and confined to the vicinity of streams or wet meadows. 

 (Nos. 2380, 2573.) 



Lotus strigosus (Xutt.) Greene, 1. c 141. Hosackia strigosa 



NUTT. 



Common on the lower slopes of the south and west sides, 

 occasionally extending into the pine belt. (Nos. 2380, 2573.) 



*Pitt. ii. 1:53 (1890).
