Limestone cliffs, 3500 to 4500 feet : Panamint Range and Grapevine Mts. in Inyo 

 Co. June. 



Geog. note. — Found only in the ranges about Death Valley, Gilia gilmanii is a notable addi- 

 tion to the list of narrow endemics peculiar to these desert mountains. Two stations are known, 

 one on the limestone cliffs just above (southerly from) Shadscale Spring in Johnson Caiion of 

 the Panamint Range (Oilman 4271, type; Jepson 19,789), the other in Titus Caiion, Grapevine 

 Mts. (Gibnan 4265). Tlie species is named for M. French Gilman, the discoverer, in recognition 

 of arduous feats of field work in highly difficult and inaccessible terrain of the desert ranges.
