to habit, but its androecium excludes it from Malvastrum, 

 and will compel its admission into either Sidalcea or Hes- 

 peralcea, unless one take it for the type of a new genus. 



3745. " Trifolium Rushyi, Greene." One may determine, 

 by a study of the original description of T. Rushyi, that Mr. 

 Parish's Bluff Lake specimens do not answer to it. These 

 call for the characterization of a new variety, which may be 

 designated 



T. RusBYi, var. atrorubens. Plant with the slender- 

 fusiform tap-root and clustered decumbent stems of the type, 

 but leaflets smaller and narrower: heads small, broader than 

 high; flowers sessile, never reflexed: calyx-teeth densely 

 white-villous: corollas of a dark red-purple, only the keel 

 with some white or pink. 



As a species T. Rushyi rests, therefore, on its peculiar 

 root character and mode of growth. The plants grow 

 singly, with tufted decumbent stems from a tap-root. T. 

 longipes, its nearest relative, forms a sod, its solitary stems 

 arising from matted horizontal rootstocks; and better 

 specific characters are seldom found in this and allied genera. 



3630. " Ribes leptanthiim, Gray." It can hardly be 

 referred to that species, even as a variety. Typical R. lep- 

 tanthum belongs exclusively to the southern Rocky Moun- 

 tains of S. Colorado, New Mexico and E. Arizona. It has 

 long slender salverform white flowers, and is confluent not 

 with this Californian shrub, but with R. microphyllum, 

 HBK., of central Mexico. But this San Bernardino shrub 

 may possibly be referred, as an outlying variety, to my 

 E,. VELUTINUM so common along the western verge of the 

 Great Basin, although the type is most unlike this in habit. 



3809. SoLiDAGO CONFINIS, Gray. The specimen in my set 

 is large and stout, some two feet of the leafy stem including 

 the panicle, having been broken off ; and in the attempt to 

 supply us with a root, and its tuft of radical leaves, our 

 friend has given us a rank specimen of root and leaves of
