narrow bracts which are gradually reduced; raceme crowded, 
becoming narrow and more or less secund, puberulent: calyx 
lobes lanceolate, 5-6mm. long, and about twice as long as the 
tube: petals greenish- or yellowish-white, suborbicular, abruptly 
acutish, or with a tooth on the subtruncate apex, as long as the 
calyx lobes: capsule narrowly linear, subcylindrical and only slightly 
enlarged downward, at maturity 20-25 mm. long and greatly con- 
torted or implexed. 
The habit and general appearance of this suggests S. decorticans (H. & A.) 
Small, from which it is far removed geographically and otherwise.

sides, May 17, 1910. 
Onagra (OrNoTHERA) ornata, n. sp.—Stout biennial, widely 
spreading from the summit of a rather large woody root; the sev- 
eral stems assurgent and simple, 5 dm. or more high, very leafy, 
densely and finely pubescent, with some scattering ciliate hairs: 
leaves narrowly oblong-lanceolate to linear-lanceloate, the largest 
10-14 cm. long, reduced toward the base and into the bracts (first 
year leaves not seen), with short dense subcinerous pubescence: 
inflorescence crowded: calyx densely white hirsute-pubescent, at 
anthesis its tube less than 4 cm. long, about twice as long as the 
ovary, its lobes as long as or longer than the tube: corolla a deep 
golden yellow, unchanged in drying or shading to orange; the 
petals broadly triangular-obovate or obcordate, as long as the 
calyx lobes: anthers yellow, 12-15 mm. long; the filaments much | 
shorter than the petals: style not protruding from the bud but 
elongating and surpassing the stamens as the buds open: capsule 
pubescent, 2-3 cm. long, somewhat thickened on the angles and 
only slightly tapering: seeds angled. 
This highly beautiful evening’ primrose, coming as it does from a state 
supposedly fairly well worked, is a distinct surprise. Doubtless, however, 
it is an indigenous plant. The excellent key prepared by Dr. R. R GaTES 
(Mo. Bot. Gar. Rept. 20:126. 1909) now makes it possible at least to place 
species of this genus in fairly well-marked groups. This proposed specie? 
will be somewhat aberrant in the O. grandiflora group. That the present 
species has nothing in common with the O. biennis group is evident not only 
from GarTEs’s key, but is attested by the well-known fact that in that group the 
petals of all the recognized western species (O. strigosa, O. Hookeri, etc-) become
