This curious form of the species, well represented by Mrs. 
Spencer’s no. 474 from San Diego County, not infrequently grows 
with the typical state in Idaho, and, according to Hall, Univ. Cal. 
Publ. Bot. iii. 238 (1907) also in California.

This handsome variant of the typical form of the species has 
been secured in Curry County, Oregon, by Professor J. C. Nelson 
(his number 1518). Dr. Hall, l.c., has shown that the plant is to be 
considered only as a variety of true C. occidentale since inter- 
mediate forms are frequently met with. 
STEPHANOMERIA EXIGUA Nutt., var. Deanei, var. nov., rams 
intricato-ramosissimis plus minusve glandulosis. — CALIFORNIA: 
1916, Mary F. Spencer, 
This is the plant to which Hall refers, Univ. Cal. Publ. Bot. ill. 
260 (1907), as follows: ‘‘ The common form [of S. exigua] in south- 
western San Diego Co. is intricately branched, the twigs very 
slender, the herbage conspicuously glandular, and the pappus that 
of the S. coronaria form. It apparently grades into S. exigua as 
regards all of these characters.’”’ Nevertheless it would seem to 
merit recognition as a variety since its glandulosity is so striking a 
character and since it so largely if not quite replaces in San Dieg° 
County the typical form. It is a pleasure to connect the name 
Deane with the flora of the region, the collector of this plant having 
secured many specimens for his brother, the enthusiastic New 
England botanist, Walter Deane, whose long interest in taxonomy 
has been so appropriately remembered by Coulter and Rose 1? 
the genus Deanea.
