Among Dr. Eisen's collection is a Rannunculus quite distinct from R. Cali- 

 fornicus, Butte, although allied; also from R. Nelsoni, var. tenells, Gray. The 

 leaves in this, not being pennately ternate, nor any tendency to a trifoliate 

 character, but are continuously trifid, and of like features consistently through- 

 out, to the least bracteoles, where it vanishes. 



Rannunculus. Eisenii. 



Stem slender, one foot high, base somewhat ascending, thence erect, panni- 

 culately branching, glabrous, or subglabrous below, sparsely pubescent above; 

 radicle leaves on very long, slender petioles, 6-8 inches, 3-parted, segments 

 cuneate, nerved, trifid, the lobes often again cut-toothed, glabrous, or very 

 obscurely a little pubescent, in general outline broadly fan-shaped with a sub- 

 cuneate base; cauline leaves of like form, on petioles 1%-% inch loug, or ses- 

 sile at the top and at length, the bractoid ones either lobed or filiform linear; 

 the slender peduncles 1-3 inches long, somewhat pubescent; sepals ye low, 

 ovate-oblong, acute, slightly pubescent, strongly reflexed, shorter than the 

 petals, oblong-subobovate; flowers about C-liues broad; akenes smooth, 

 scarcely a line long, a little flattened, edges from sharp becoming somewhat 

 obtusely rounded, beak strong, short and recurved; heads compact globular, 

 2-lines in diameter. 



Scutellaria Bolnderi, Gray., in Dr. A. G. Ei-sen's collection, hnve ovate 

 leaves, or perhaps ovate-oblong, and al are essentially on pet. oh S, 3-1-line 

 long, in 1-2 of the topmost pairs (out f twenty-five pairs) only suhstssile — 

 all distinctly serrate, with coarse truncate teeth below the upper third. 



Clematis liqusticifolia has from 4-6 or 8 sepals, top of the climber pubescent, 

 leaves 2-6 inches loug (petioles) of 3-pairs and odd leaflet, the lower pair 

 again ternate, pubescent beneath and on the margins; genitals scarcely half 

 as long as the sepals (exceptional?); outer filaments widely flattened or peta- 

 loid. 



In* specularia biflpra, Gray, Dr. Eisen's specimens exhjfbit some features 

 worthy of note. Steins ascending, branching from the base, angled, short re- 

 flexed; strigose or strigulose-hispid along the angles, chiefly below, only seab- 

 rulose backwards above; lower leaves obovate obtuse, more or less decurrent 

 into peti >les %-inch long, or about half the length of the lamina to very shorty 

 and so sessile to clasping (3-6 inches above the base); flowers 1-3 in the ax- 

 ils; otherwise as described. 



Dr. Burleigh presented to the Academy's Herbarium a small Gentiana, of 

 the stipitate group, closely allied to 9. glauca, from St. Paul's Island, Alaska, 

 but as in the description of that species no notice is taken of the denticulate 

 lobes of the flowers, etc., we furnish the following description: 



Gentiana glauca, var. Paulense. 



Stem %-2 inches high, erect or ascending, often branched from the base; 

 perennial root of creeping and thickened fibres; lower leaves obovate-cuneate, 

 decurrent into short-winged petioles, above ovate sessile, about %-inch loug, 

 %-inch wjde, fleshy, smooth on the margin, 3-nerved and reticulated base, con-
