Plagiobothrys Harknessii (Greene), n. comb.—Sonnea Hark- 
nessit Greene, Pitt. 1: 23. 1887.—Quite distinct from P. Kingii, its 
nearest relative, as GREENE has well shown (/.c.). The following 
representative collections indicate that its range is much greater 
than originally supposed. Nervapa: Eagle Valley, Ormsby 
County, June 10, 1902, C. F. Baker (1046); CALIFORNIA: Sierra 
County, 1875, J. G. Lemmon (794); OREGON: near Desert Well, 
8 miles south of Big Springs, July 5, 1894, J. B. Letberg (403). 
Plagiobothrys foliaceus (Greene), n. comb.—Sonnea foliacea ° 
Greene, Pitt. 1: 222. 1888.—This seems to be a well marked species, 
the dorsal depression of the nutlets being particularly unique, but 
it is apparently still known only from the original collection. 
The maintenance of Sonnea Greene (I.c. 22) does not seem to be 
at all desirable. Although, as pointed out by GREENE, the charac- 
ter of the scar in this group is somewhat different from that of the 
‘other species of Plagiobothrys, the plants are habitally the same 
when one takes the genus into consideration in its entirety. More- 
over, the scar character is not so characteristic in all the species as 
might be desired if they are to be removed from true Plagiobothrys. 
In this connection Jones has called attention to the fact that P. 
Jonesii (S. Jonesii [Gray] Greene) is an Amsinckia in everything 
but its white flowers (Contrib. West. Bot. 12:57. 1908). The 
pubescence of P. Jonesii and the tesellated nutlets surely suggest a 
relationship.to A. tessellata, but the white and short corollas that 
are so widely at variance with the long yellow ones of Amsinckia 
are perfectly congeneric with the SoNNEA section of Plagiobothrys. 
Altogether, Sonnea would seem superfluous in a group of genera 
already merging, but which, with Sonnea eliminated, seem well 
enough marked when dealt with in their aggregates. 
Cryptantha vinctens, n. sp.—Annual, 10-15 cm. high, rather 
sparsely pilose or hispidulous, the leaves more or less papillose;
