use of the name was by Dr. Gray (1. c.) and although he cited Watson's 

 variety as a synonym his description is entirely based on Fendler's 

 plant. Furthermore, Article 47 of the International Rules states, 

 " When a species .... is divided into two or more groups of the same 

 nature, if one of the forms was distinguished or described earlier than 

 the other, the name is retained for that form." The name fulvo- 

 canescens must apply, then, to Fendler's plant, since it was first dis- 

 tinguished and first described as a species. Accordingly it is rather 

 the plant collected by Watson and wrongly included by him in his 

 description of fulvocanescens as a variety of glomerata which needs 

 the new name unless already described. The latter alternative seems 

 to represent the truth. Jones (1. c.) and Greene (1. c. Ill) were 

 evidently writing about the same plant; and when Dr. Gray proposed 

 the name sericea he included under it his earlier Eritrichiwn glomera- 

 tum, var. humile. The material in the Gray Herbarium would indi- 

 cate that he was justified in this; but Dr. Greene in using the name 

 specifically, wrote " E. glomeratum, var. humile Gray in part." There- 

 fore, if 0. humilis Greene is distinct from 0. sericea, the Watson plant 

 from Nevada discussed above must bear the former rather than the 

 latter name. 



Oreocarya oblata (Jones), comb. nov. — Krynitzkia oblata Jones, 

 Contrib. W. Bot. xiii. 4 (1910). Very distinct from all other species 

 having long white corollas. 0. Shockleyi Eastw. and K. me^isana 

 Jones are the only other members of its immediate group. The latter 

 is probably a good species, nearer the former than is 0. oblata, but I 

 have seen no specimen. 0. oblata probably is not uncommon in 

 Arizona, New Mexico, and Texas. Specimens examined: Texas: 

 among rocks (corolla white), El Paso, March, 1851, George Tlmrber, 

 no. 147, Sept. 1884, Marcus E. Jon.es, 1881, G.R. Vasey, March, 1885, 

 Asa Gray. New Mexico: 1851-52, C. Wright, no. 1566, in part. 



Cryptantha barbigera (Gray) Greene, var. inops (Brandegee), 

 comb. nov. — Krynitzkia barbigera Gray, var. inops Brandegee, Zoe, 

 V. 228 (Sept. 1906). Mrs. Brandegee on one of her labels has rightly 

 cited us synonyms of the above variety, C. nevadensis Nels. & Kenn. 

 and C. arenicola Heller, published two and three months later respec- 

 tively. The very slender acuminate nutlet is the principal character 

 of the variety. The muriculations, especially near the tip of the fruit, 

 are often very sharp. A specimen collected by Dr. Gray in the Grand 

 Canon in 1885 and included by him in the species must now be 

 referred to the'variety.
