14 Contributions from the Gray Herbarium 
paullo pubescentibus. — CALIFORNIA: stony slopes, Mountain 
Springs, Colorado Desert, March 18, 1917, Mary F. Spencer, no. 
561 (typE, Gray Herb.). 
This species is most nearly related to L. Haydoni (Orcutt) 
Greene which is essentially glabrous and has subequal corolla and 
calyx and smaller leaves. In Pitt. ii. 133-137 (1890) Greene 
showed the naturalness of the genus Lotus when considered as 
embracing the groups sometimes segregated as distinct genera, in 
Hosackia, Syrmatium, etc. When viewed in its entirety the group 
must be treated (if considered logically) in one of two ways. 
Either Greene’s interpretation of the genus must be accepted or 
the numerous segregate genera must all be adopted, for to recog- 
nize one (as some have done in the case of Hosackia, for instance) 
will necessitate the acceptance of the others which have quite as. 
good claim to generic recognition. It is not conceivable that any 
“‘ conservative ”’ botanist will endorse this segregation of a group 
which, when considered in the largest sense, forms a very natural 
entity. 
Eroprum cyGnorum Nees. So far as I have been able to dis- 
cover, Mrs. Spencer’s specimens from San Diego (to be distributed 
under her number 227) furnish the first record of the introduction — 
into the United States of this Australian species. According to 
Bailey this plant exhibits, in its native land, the same weedy pro- — 
pensity displayed by E. cicutarium. The question may be rai 
whether it will become as completely established in this country a8 
the latter which has spread so rapidly in the last decade. 
v Fremontia mexicana (Davidson), comb. nov. Fremontodendron — 
mexicanum Davidson, Bull. So. Calif. Acad. Sci. xvi. 50 (1917). 
Despite the presence in botanical literature of the name Fre 
montia for more than one group of plants, its valid use, according 0 
Art. 50 of the International Rules, is restricted to the sterculiaceous 
group of which the above species is a member; for where the name 
elsewhere occurs it is universally regarded as a synonym. Besides 
co-type material (Dr. Davidson’s no. 3234) there is a specimen 2 
the Gray Herbarium bearing no data except “ San Diego, Cleve- 
land ” which is to be referred to this species. As indicated by Die 
Davidson, I. c., the species is an excellent one readily distinguished 
from F’. californica by the glabrous pit at the base of the sepa!s- 
In the latter species the pit is densely hairy.
