THE GENUS BOSSEKIA. 211 
of generic names—Bossekia among the rest—of which the au- 
thors of that nevertheless invaluable treasure of learning had 
no knowledge. It is but one of not a few names for genera 
which do not appear among the synonyms even. 
Even as to the intended meaning of it Rudacer is a failure, 
for the purpose must have been that of saying in Latin Maple- 
leaved Raspberry, and what is said is Red Maple; for “acer ” is 
the substantive and “rub” is but the qualifying adjective. The 
author himself has placed this beyond dispute, unwittingly to 
be sure, by giving neuter endings to the trivial names, such as 
are always given in Acer but never in Rudus. 
The following are the early species of BossEKIA: 
B. oporata. Cornut. Canad, under Rubus. 
B. PARVIFLORA. Nutt, Gen. < X 
New Plants from New Mexico. 
RANUNCULUS NuUDaATus. Stems mostly solitary, erect from 
an unusually large fascicle of fleshy-fibrous roots, naked and sim- 
ple below, parted near the middle into a few strict often sub- 
umbellate flowering branches: radical leaf often solitary, on a 
long and slender petiole, pedately 5-parted, the divisions trifid, 
their segments oblong to oblong-linear, obtuse, those subtending 
the peduncles sessile, of 3 linear entire divisions, both stem and 
leaves sparsely villous-hairy; sepals thin, ovate, villous-hairy, 
caducous, not reflexed; corolla yellow, }-inch broad; petals 5 
to 8, obovate-oblong to oblong; achenes not seen.

Of peculiar habit, but related to R. acriformis of Wyoming. 
ERIGERON DEUSTUS. Perennial, slender, freely branching, 6 
or 8 inches high, minutely hirtellous-strigulose ; leaves about an 
inch long, oblanceolate, acute, entire; heads scattered, termi- 
nating slender pedunculiform branches; involucres nearly hemi- 
spherical, 4 lines broad, not as high, their bracts equal, acute, 
sparsely hirtellous; rays 60 or more, very narrow, purplish ; 
achenes not seen.
