crossing' of the creek west of Caliente, Kern county. It is very 

 abundant all through that part of the country, literally covering 

 the rocks in many places, notably on the ridges about the mouth 

 of Kern canyon. This species is perhaps more abundant in the 

 southern part of the State, where it was originally collected by 

 Bigelow, but is also plentiful east of San Jose, Santa Clara 

 county, on the ridges above Alum Rock Park. It is easily dis- 

 tinguished from the other species by its slender, rather long 

 branches. 



Selaginella hansrni Hieron. Hedwigia, 39: 301. 1900. 



No. 7583, collected March 22, on a low ridge directly east 

 of South Butte, Marysville Buttes, Sutter county, where it is 

 plentiful, almost covering the rocks and stones in many places. 

 This is also a well marked species, the fronds being short and 

 broad. The type is Hansen's 878, collected near FLsher's Cabin 

 on the Mokelumne river, in either Amador or Calaveras county, 

 April, 1893. Specimens are also cited from the Oakland Hills, 

 collected by Hillebrand, and from Fresno county by A. A. 

 Eaton.

 1879. 

 No. 7703, collected some miles east of Mojave at Rands- 

 burg, Kern county, April 14, elevation 3300 feet, where it is 

 rather plentiful on the desert hills. These specimens were in 

 flower only. The type should probably be some specimen of 

 Watson's no. 1 108 of Bot. King Exped. 329, but the first defi- 

 nitelv recorded specimen is ''(Fort Mohave, Cooper)." 



No. 7743 was obtained in fruit in a guUey at Oil City, op- 

 posite Bakersfi.eld, Kern county, April 22, elevation about 500 

 feet. It was less abundant here than in the desert.
