calyx gibbons or even spurred at base, and the lobes more elon- 

 gated; legumes oblong, 3-5-seeded. Of exactly the habit of tin- 

 last, with stems 1 foot high, the raceme nearly sessile, and 

 scarcely exceeding the leaves. Collected by Anderson (92 and 



232) and also by Dr. Torrey (88) in the same region with the 

 Inst, near Carson City." 



If any dependence can be placed upon the character "ra- 

 cemes nearly sessile, and scarcely exceeding the leaves," this 

 should be a well marked plant. In the Bibliographical Index 

 he refers it to L. holosericeus Nutt. the type of which was col- 

 lected on "islands and gravelly banks of the Wahlamet" not far 

 from Portland, Oregon, by Nuttall. This is described as closely 

 related to the Californian L. albifrons, but with "flowers about 

 half the size." It is probably not fonnd in Nevada'. 



THE SOUTHERN CALIFORNIA JUNCACEAE— I 

 By S. P.. Parish 



The material available for a study of the rushes of southern 

 California is less abundant than is desirable. Besides my own 

 collection I have had, through the kindness respectively of Dr. 

 H. M. Hall and Professor LeRov Abrains, the opportunity of 

 examining the Jnncaceae in the herbaria of the University of 

 California and of Stanford University. Mr. F. Y. Coville has 

 compared a few critical specimens with the material in the Nat- 

 ional Herbarium. To Mrs. Charlotte M. Wilder I am under 

 grateful obligations for the drawings, made from fresh material, 

 illustrating /uncus rugulosus. 



JUNCACEAE

 uted.
