lacustre molle. Meanwhile Mr. Marcus E. Jones, in 1895, had 

 published* a Hibes lacustre lentum based on specimens collected 

 at an elevation of about 10,000 feet in the Henry Mountains 

 and on Belknap Peak, southern Utah. In publishing the variety 

 the author called attention to the possible identity of lentum 

 and molle, a point that could only be determined by an examina- 

 tion of the type specimens of the latter. This has now been 

 done and shows the two to be the same. 



My attention was recently called by Professor C. V. Piper to 

 the fact that among the specimens referred by Gray to his 

 Mibes lacustre parvulum] are some which belong in reality to 

 Hibes lacustre molle Gray, and the suggestion was therefore 

 made that the varietal name jyarvtdum should be taken up as the 

 specific name of the plant under discussion. In his original 

 description Dr. Gray characterized his variety as with nearly 

 glabrous leaves, smaller than those of the type form of lacustre, 

 as occurring in "the Rocky Mountains and north to British 

 Columbia," and as having been mistaken formerly for liibes 

 setosutn. An examination of the material in the Harvard Her- 

 barium shows that Dr. Gray named as Hibes lacust?'e parvulum, 

 six specimens which he had formerly determined as setosum, as 

 follows: 



"Rocky Mts. Hook. Dupl. Fl. Bor. Am. 'i?. oxyacan- 

 thoides. ''''"' 



"Hort. Cantab. Anno 1846 (178 Loddiges)." 



"Isle St. Ignace, L. Superior."

 The first three of these are lacustre-like. plants with smooth 

 and small leaves, while the last three are Hibes lentum. We 

 have therefore no definite fixation of the type in the original 

 specimens. Turning to the [customary treatment of parvuhmi 

 in herbaria and published papers, we find that botanists have 

 applied the name either to the small and smooth-leaved, black- 

 fruited plant so frequent in the northern Rocky Mountains, or,
