mon. Leaflets about 3 lines, flowers 3 or 4 lines, and legume about 

 half an inch in length. The legume refers this well-marked species, to 

 the Injiati section, but it has no particular resemblance to any other 

 species. I wish it to bear the name of one of the two valued corre- 

 spondents who discovered and communicated it, namely, Mis. Pulsifer- 

 Ames, to whom and to Mr. Lemmon we are mainly indebted for our 

 knowledge of the botany of Sierra and Plumas Counties in the north- 

 ern part of the Sierra Nevada. 



Prunus (Emplectocladus) fasciculata. EmplectocJadus fasci- 

 culatus Torr. PI. Frem. in Smiths. Contr. p. 10, t. 5. To this (not- 

 withstanding the more marked presence of a style and the ovules not 

 really suspended from the summit of the cell) I venture to refer a 

 flowering sjjecimen collected in the northei-n j^art of Arizona by Dr. 

 Newberry, fruiting ones collected in the southern part of Utah (at St. 

 George) by Dr. Palmer, in 1S71, and both flowering and fruiting 

 ones from the latter district, no. 56 of Dr. Parry's collection in 1874. 

 A thin disk lines the tube of the short-campanulate calyx up to the 

 origin of the calyx teeth, the edge of which is slightly free or salient. 

 The flowers in the specimens at hand appear to have a sterile ovary, 

 but in most cases surmounted by a rather slender style longer than it. 

 Dr. Torrey's figure appears to represent a fertile ovary ; but our fruit 

 shows a style a line and a half in length. Otherwise Dr. Torrey's 

 Emplectocladns seems to be identical with the plant before us, and 

 it came from the same district. The fruit is globular, 5 or 6 lines 

 long, hirsute-tomentose ; sarcocarp very thin, in the dry state coria- 

 ceous : putamen globular, smooth, and even, neither sutui-e prominent. 

 Leaves involute-conduplicate in vernation. — Having recently been 

 favored with a fragment and flower from Dr. Torrey's original speci- 

 men of Emplectocladus, the suspected identity is verified. This name 

 may now be appropriated to the group of American species of which I 

 had referred, one to Amygd(dus, and others to Microcerasus of Webb, 

 but which form a well-marked section by themselves.*
