3:343- In the variety proposed the petals are not emarginate, the calyx 
lobes are longer than in the species; the presence of a rather conspicuous 
ciliate-pubescence on the margins of the leaf in the variety adds another 
point of contrast. 
Excellent specimens are in hand from Jennie M. Archibald, Berwind, 
Colorado, 1g00, no. 236. 
Parosela Porteri, n. sp.—Caudex woody, with a deep- 
set woody root: stems numerous from the enlarged crown, 
prostrate-assurgent, quite unequal in length, 10-25 long 
(including the oblong spike), strigose, appressed-pubescent : 
leaves trifoliate, densely appressed strigose-silky, cuneately 
obovate or narrower, mostly obtuse, 8-14™™ long, the terminal 
one longer than the lateral pair, barely petiolulate, generally 
Shorter than the slender petiole; stipules slenderly and stiffly 
setaceous, 5-6™" long: spike dense, 2~5™ long; bracts purple, 
lanceolate-acuminate, equaling or shorter than the calyx, silky- 
villous ; calyx tube campanulate, membranous with ten greenish 
nerves, the triangular base of its lobes abruptly narrowed into 
long slender plumose setae which are twice as long as the tube; 
corolla lemon-yellow; the standard very short, reniform-triangu- 
lar, acute, broader than long, shorter than the slender claw; the 
wings oval, short clawed; keel petals oval or even broader, sur- 
passing the wings, the blade about 6™ long and the claw about 
am; Ovary silky, included in the calyx tube, half as long as the 
slender plumose style which is much exceeded by the calyx lobes. 
The somewhat varying descriptions of Parosela Jamesii indicate that 
more than one species has been distributed under thisname. That the species 
now proposed is the Dalea Jamesti of Porter, F7. Colorado, seems probable, 
but from the original as described in T. & G. FZ. V. Am. 308, the following 
points seem to separate it. . Porteri is more prostrate spreading, the 
leaves are narrower and are shorter than the petioles, the pubescence is 
Coarser, it has purple bracts, the flowers are yellow not purple, and the wings 
and keel are oval not oblong as in P. Jamesii.*

Petalostemon pubescens, n. sp.— Roots woody; the crown 
_thick, simple or branched: stems numerous, the exterior ones 
*Dr. Gray in redrawing the description for Pl. ce 49, seems to have so modi- 
fied the original description as possibly to include P. Porter7.
