nothing. It is very doubtful if the several segregate species proposed 

 in this group can be maintained as they are founded on these or other 

 characters equally trivial. However, the variation treated here is so 

 striking in its extreme form that it is worthy varietal designation. 

 Since Dr. Greene failed to indicate any definite specimen, the following 

 representative collections are noted. Specimens examined: Colo- 

 rado: plains, Pueblo, 1873, Edward L. Greene (type). New Mexico: 

 Mogollon Mountains, on the middle fork of the Gila River, Socorro 

 Co., August 9, 1903, 0. B. Metcalf, no. 431. Arizona: vicinity of 

 Flagstaff, June 4, 1898, Dr. D. T. MacDougal, nos. 40, 204. Mexico: 

 Casas Grandes, Chihuahua, May 13, 1899, E. A. Goldman, no. 407. 



Oreocarya suffruticosa (Torr.) Greene, var. abortiva (Greene), 

 comb. nov. — 0. abortiva Greene, Pitt. iii. 114 (1896). Krynitzkia 

 imdticaulis Torr., var. abortiva (Greene) Jones, Contrib. W. Bot. 

 xiii. 5 (1910). Jones (1. c.) has pointed out that the incurving of the 

 nutlets is a characteristic common to all members of the group. 

 When only one nutlet forms (as is sometimes the case in this plant 

 and also in others) the ventral keel is larger than when more mature. 

 It then, of course, seems to end even more abruptly. The Californian 

 plant simply represents an extreme in this matter. It is otherwise 

 allied to 0. suffruticosa rather than to the other species of the group. 

 See the remarks by Parish, Eiyth. vii. 95 (1899), which further 

 prove the plant to be unworthy specific rank. 



Oreocarya virginensis (Jones), comb. nov. — Krynitzskia gloincrata 

 (Pursh) Gray, var. virginensis Jones, Contrib. W. Bot. xiii. 5 (1910). 

 Very distinct from 0. glomerata, which has narrowly ovate not at all 

 winged nutlets. Besides the specimens from La Verkin and Diamond 

 ^^alley, Utah, cited by Mr. Jones, another from the same region, viz.: 

 no. 173 by Dr. C. C. Parry, 1874, is of this species. 



Oreocarya sericea (Gray) Greene, Pitt. i. 58 (1887). — 0. humilis 

 (Gray) Greene, 1. c. iii. 112 (1896) ? Krynitzkia sericea Gray, var.

 Acad. x. 61 (1875) i. e. Krynitzkia echinoides Jones, 1. c. 709. Mr. 

 Jones (1. c.) assigned a new name to the plant collected by Fendler in 

 New Mexico and labeled in herb, by Dr. Gray " E. fulvocanescens," 

 on the ground that the name must be applied to a very different plant 

 collected by Watson in Nevada (no. 853), because this was the plant 

 for which the name was first published. It is true that Watson took 

 his no. 853 to be Gray^s fulvocanescens in herb.; but the first specific
