MACKENZIE: Notes oN CAREX—XII 374 
of Schweinitz with the plant treated in this article and generally 
as Carex albolutescens can be readily understood. The two 
species really stand next to each other, and as long as genuine 
Carex straminea was not understood and kept separate, it was 
a natural thing to do to identify the plant of Schweinitz in the 
way that was done. The name, however, has always been 
inappropriate, and one is glad to be able to reduce it to synonymy. 
t now appears that the plant treated in this article and gen- 
erally as Carex albolutescens (‘‘ Carex albolutescens Schw.”’ Kiik- 
enth. in Engler, Pflanzenreich 42°: 208; Mackenzie in Britton 
& Brown, Ill. Fl. (2d.. ed.) 1: 385. f. g4z [excluding var. cumulata 
Bailey]; Robinson & Fernald in A. Gray Man. (7th. ed.) 219. 
pl. 351 [left hand] excluding var. cumulata Bailey; ‘‘ Carex foenea 
Willd.’’ Boott, Ill. Carex 3: 118, pl. 375) is withoutaname. It 
therefore gives me much pleasure to be able to name it for that 
excellent field man and acute student, Mr. Bayard Long, as Carex 
Longii. A specimen collected July 24, 1907, by Mr. Long at Cold 
Spring, Cape May County, New Jersey, and preserved in the 
herbarium of the Philadelphia Academy of Natural Sciences is 
designated as the type. _
