There appears to be not a little confusion with regard to the num- 

 bers of the collections made in the southern Sierra by C. A. Purpus; 

 his no. 1409 represents a case of this confusion. This number is assigned 

 by Rydberg as the type of Horkelia chaetophora Rydb., (Bull. Torr. 

 Bot. Club, vol. 26, p. 543. 1899; Ivesia chaetophora Rydb., N. Am. 

 Fl., vol. 22, p. 290. 1908), with locality "Farewell Gap and Little 

 Kern River," Tulare County, and the type is said to be deposited in 

 the herbarium of Mr. T. S. Brandegee; the Brandegee Herbarium is 

 now at the University of California. Search at Berkeley disclosed 

 two collections bearing the no. 1409, one from "Rocks, Little Kern 

 River, 10-11,000 ft.," and the other from "Kaweah Peak, 11-12,000 

 ft."; no collection from Farewell Gap with no. 1409 has been seen. 

 /. chaetophora is said to be distinguished, in the generic key to the 

 species in the N. Am. Flora, from /. pygmaea by having 10 stamens, 

 5 stamens being assigned there to 7. pygmaea, but in the description 

 of I. pygmaea on p. 289, the number of stamens is said to be " 5-10. ' ' 

 It is possible that neither of the specimens seen by me is the type of 

 L. chaetophora; certainly the two sheets of Purpus 1409 now at Berke- 

 ley differ in no perceptible way from typical 7. pygmaea,.
