about 7™™ long, slightly longer than the calyx lobes and stamens, 
equalling the style; stamefs similar and equal: capsule slender, 
tapering to summit, ascending, somewhat bent or contorted, about 
2°™ long. 
This has passed as S. Boothit Dougl. Similar as the descriptions seem, the 
two plants are quite distinct in appearance. S. Boothit is glabrous and with 
shreddy bark on the older'stem; it branches mainly near the base, the branches 
also branching; its flowers are much smaller, and the capsules are shorter and 
more contorted. 
The type is J. G. Lemmon, no. 103, eastern flank of Sierra Nevada, Cal. 
1875. Two good specimens, both in herb. Mo. Bot. Garden. 
20. S. Hitchcockii (Lévl.), n. sp.; Oenothera gauraeflora Hitch- 
cockii Lévl., Monog. Oenothera, 226.—Softly hirsute or ciliate, 
branched from the base, 15-25°™ high; branches slender and more 
or less paniculately branched above: root leaves oblong, irregularly 
dentate, about 3°™ long, tapering into a petiole one-half as long; 
stem leaves smaller, bract-like, sessile, broadly linear or lanceolate: 
flowers crowded in bracteate secund racemes; calyx tube slender, 
scarcely enlarged at summit, as long as the linear-lanceolate lobes; 
petals white, obovate, 3-4™™ long, scarcely longer than the calyx. 
lobes and the stamens; style slender, longer than the petals: cap- 
sules slender, 12-18™™ long. 
This very excellent species rests upon two specimens in herb. Mo. Bot. 
Garden. One bears the data “Simpson Park, July 6th, 1859 (?),” and in pencil 
“nothing like it known to me;” the other is blank, but both look as if they were 
from the same collection.

The following are, so far as the writer knows, still unknown except — 
from the original specimens and descriptions. So far as one may — 
judge from descriptions, they are valid and will no doubt again 
come to light.
