THE CALIFORNIA PAROSELAS 
S. B. PARISH 
(WITH FIVE FIGURES) 
This paper is based on a study of the ample collections in the 
herbarium of the University of California, and of the material in 
the private herbaria of Dr. A. DAavipson and of the writer. While 
the numerous extralimital material in these collections has been 
carefully studied, the citation of specimens is confined, for the most 
part, to those collected within the boundaries of the state. Dr. 
HAL not only placed the collections of the University at the 
writer’s disposal, but allowed him the use of a preliminary study 
which he had prepared, and most generously aided him in other 
ways. For the drawings, from which the figures have been repro- 
duced, the writer is under obligations to the skillful pen of Mrs. 
CHARLOTTE M. WILDER. 
The generic name 
The genus Dalea was founded by Linnaeus in 1737, in his Hortus 
Cliffortianus, but in the Species Plantarum of 1753 he reduced it 
to Psoralea. The latter year being now accepted as the initial 
date for phanerogamic nomenclature, we are debarred from going 
back to LINNAEUvs’ earlier use of the name. It was revived by 
JussIzv in 1789, and according to present rules that must be taken 
as the authoritative date for the name, and it is with this citation 
that it is maintained in the new Gray’s Manual.t Unfortunately, 
in the interval it had been used for two other genera. In 1756 P. 
Brown applied it to what is now universally regarded as Eupato- 
rium, so that, as a synonym, his use may be disregarded. But 
GAERTNER, in 1788, gave it to what ENGLER and Prantt and the 
Kew Index now call Microdon Choisy (1823). This scrophulariace- 
ous genus, therefore, has the prior title by a single year, and the 
leguminous genus must take the later name Parosela Cav. (1802). 
tIn the Natiirlichen Pflanzenfamilien, Dalea Linn, is retained.
