doubtful. I have never seen it from such high altitudes, which are gener- 

 ally occupied by Jimiperus occidentalis. The species is distinguished from 

 every other Juniperus by the larger number of cotyledons, the others having 

 only two. 



Libocedrus decurrens, Torr. — North Fork of Kern River (423). 



ORCHIDE^. 

 Epjpactis gigantea, Dougl. — Harriett's Canon, Santa Barbara (117). 

 JUNCE^E. 

 By Dr. George Enoelmann. 



Juncus acotus, Linn., var. sphjerocarpus, Engelm. — Near the sea- 

 coast, Santa Barbara (102). — Mr. Watson has directed attention to the fact 

 that this form has a more elongated, stricter panicle, with smaller, sub- 

 globose capsules, and seeds with shorter appendages. I find the same in 

 the South American specimens, and in those of Cape of Good Hope. The 

 name of J. macrocarpus, which Nees has given to this latter, would not be 

 appropriate for this form, as the capsules are actually smaller than in the 

 Mediterranean plant. I cannot consider these slight differences as of specific- 

 value, as we find the like in several other species of this genus. 



Juncus dubius, Engelm. June. 459. — Walker's Basin, at 3,300 feet 

 (287). 



LILIACE^E. 



Yucca Whipplei, Torr. — Santa Barbara (135). 

 CYPERACE^E. 



Eleocharis palustris, R. Br. — Santa Barbara (58). 



Eleocharis acicularis, R. Br. — Santa Barbara (80). 



Scirpus validus, Vahl. — Santa Barbara (57). Walker's Basin, at 3,440 

 feet (286). This is the well-known Tule of California, forming dense 

 masses along lake and river shores, from 4 to 10° high.
