bracts aristate from a broad searious base, shorter, or rarely 
much longer than the heads; scales equalling or exceeding the 
perigynia, the green midvein excurrent as a short, nearly 
smooth awn; perigynia castaneous, ovoid, thick, neryed or 
nearly nerveless, produced at base, 4 mm. long, contracted to 
a lone, serrulate beak; achenes ovoid, 2 mm. long, entirely 
filline the body of the perigynium.

Dr. E. lL. Greene writes me that Piptocalyx is invalid by rea- 
son of a prior genus of the same name, and also that he does 
not approve of the name Greeneocharis proposed by a Huropean 
author to take its place. Therefore I propose to name the 
genus In memory of Walter Wheeler, a young amateur botanist 
of Southern California who was instantly struck dead by light-— 
ning on July 25, 1904, while botanizing on the very summit 
of Mt. San Gorgonio, or ‘*Grayback,’’ the highest peak of the 
San Bernardino range and about twelve thousand feet above 
the sea level. 
Wheelerella of Borraginacex. 
Piptocalyx Torrey. 
Krynitzkia, sub section Piptocalyx Gray. 
The genus comprises two diminitive annuals of the Asperi- 
folie and ranges from Lower California and Arizona through 
the arid regions as far as British Columbia. They are from 
one to four inches high and are easily mistaken for Cryp- 
tanthes. 
Wheelerella circumcissa (H. & A.) 
Found sparingly in Los Angeles County mountains and 
throughout the given range. Seldom over two inches high, in 
tufts in very dry, sandy soil. 
Wheelerella dichotoma (Greene). 
So far reported only from Western Nevada. Very similar 
to the last but somewhat larger and coarser.
