NEW OR NOTEWORTHY SPECIES. 15 
loose: upper petals white, the flower otherwise of a clear 
blue. - 
At middle altitudes of the West Humboldt Mountains, 
Nevada, in dry rocky soil in the shade of junipers, collected 
by the writer in July, 1894. Species with something of the 
aspect of D. Columbianum, that is, D. pauciflorum, Nutt.; but 
the roots of that are almost round-tuberiform ; so that the 
present plant is more allied to D. scaposwm, to which, how- 
ever, it bears less general resemblance. 
DELPHINIUM GRACILENTUM. Slender, usually 2 feet high 
or more, from a grumous-tuberiform root, sparsely leafy, 
pale green and glaucescent, appearing glabrous, a lens re- 
vealing short stiff white hairs at the base of the stem, and 
again upon the small bracts of the inflorescence: radical 
leaves few, long-peduncled, 2 or 3 inches broad, deeply about 
5-parted, the lobes mostly oval or oblong, obtuse and entire; 
lower cauline more cuneately cleft, and the segments 3-lobed: 
racemes long, slender and lax: flowers small, deep blue 
(pink in the frequent albino state), the stoutish slightly 
curved spur little exceeding the oblong sepals: follicles 
slightly divergent. 
Middle elevations of the Sierra Nevada, California. It is 
the D. patens of my Flora Franciscana, and I formerly sup- 
posed it to be the plant which Bentham so named ; but, hav- 
ing seen the specimens on which D. patens was founded, I 
am certain that that is only D. decorum ; not even a variety 
of that species. In the “D. patens” of my Flora I included 
a plant which is of a“ deeper green, and glandular-pubes- 
cent" This I think will prove to be another distinct species 
of the Sierra Nevada, though Iam not yet able to assign 
characters enough to warrant its publication. Its root is 
still unknown to me.

RHAMNUS PIRIFOLIA. Tree about 20 feet high, the naked 
trunk 4 or 5 inchesin diameter, clothed with a smooth bark :
