Dalea aurea var. elatior A. Gray, Pl. Wright. 1: 46. 1852. 
Datea rubescens S. Wats. Proc. Am. Acad. 17: 369. 1882. 
Parosela rubescens A. M. Vail, Trans. N. Y. Acad. Sci. 14: 34. 
1894. 
Intermediate beacon P. aurea and P. nana, The bracts 
are narrower and longer than those of either of the above species, 
the corolla turns red¥ish-purple and the leaves are usually less 
villous. 
PaROSELA WISLIZENI (A. Gray) A. M. Vail, Trans. N. Y. Acad. 
Sci. 14: 34. 1894. 
A little-known species which shows great variation in the 
color of the flowers, some of them being lilac, others rose-colored 
and others again rose-colored with the standard ochroleucous and 
in the latter case closely resembling those of Parosela lasiostachya 
(Benth.), which species is glabrous throughout with somewhat 
fleshy leaves. P. Wislizeni may not be more than a pubescent 
form of the latter species. In Herb. Canby, preserved in Herb. 
N. Y. College of Pharmacy, a specimen of P. /astostachya collected 
by Parry and Palmer, no. 15, from near San Luis Potosi shows the 
characteristic acute leaflets of that species, the upper ones being 
faintly silky villous and identical with those of some smoother 
forms of P. Wislizent. 
PAROSELA WISLIZENI SESSILIS (A. Gray). 
Dalea Wislizeni var. sessilis A. Gray, Proc. Am. Acad. 16: 105, 
1880, | 
A very noteworthy variation. A low shrub with spreading 
slender branches and short racemes of showy, rose-colored flowers . a 
sessile on the short, lateral branchlets. The general appearance of ae 
the plant is that of Parosela formosa (Torrey), and in several in-_ a8 
stances has been confounded with it. The leaflets are very small, a 
greyish-green, silky-pubescent or rarely glabrate, with small dark — x 
glands on the lower surface, and are not at all fleshy. The bracts 
are oblong or oblong-lanceolate, caducous, the keel petals are : 
remarkable ‘for the two linear-oblong glands i in the form of av ee a 
the apex and the dunetoonnes So gentler
