The leaflets are somewhat larger, rarely with a slight minute puberu- 

 leuce beneath. — T. Fendleri, Gray, of the Rocky Mountains 

 (Colorado and Utah to New Mexico), is a rather low slender species, 

 glabrous or somewhat pubescent, with usually small leaflets (2 to 9 

 lines long) and an open spreading panicle ; anthers setosely acuminate ; 

 fruit slightly glandular-puberulent, oblong to ovate, acuminate, 2 or 3 

 lines long; seed broader and somewhat flattened, 1^ lines long. 

 T. Wrightii appears to be a form with fruit smaller than usual. 



Ranunculus ambigens. In wet places, glabrous, the ascending 

 stems stout and elongated, often rooting at the lower joints : leaves 

 oblong- to linear-lanceolate, 2 to 5 inches long, acute, sparingly den- 

 ticulate, petiolate ; petiole margined, clasping : petals (2 lines long) 

 but little exceeding the sepals : carpels in small ovate heads, turgid, 

 rarely a line long, with a long straight narrowly subulate beak. — 

 R. alismcefoliiis, Benth. PI. Hartw. 295, as to the eastern plant, and 

 Gray, Manual, 41. From Maine to Illinois. — R. ALiSMiEFOLius, 

 Geyer, to which this has been referred, has an erect stem (a foot high 

 or more, the alpine form often dwarf) from a fleshy-fibrous root, 

 glabrous excepting the hairy basal sheaths ; leaves entire, the radical 

 on elongated petioles, the few cauline sessile or nearly so ; petals 

 larger (2 to G lines long) ; fruiting heads usually larger, the more 

 flattened carpels over a line long, with a short narrow beak. It is 

 found in the mountains from Colorado and Wyoming to California 

 and Oregon. The var. montanus of King's Rep. is the typical subal- 

 pine form as found by Geyer. 



Dentaria Californica. Stem simple or branched, about six 

 inches high : leaves thick, 2 to 4 on the upper part of the stem, on 

 short petioles, ovate to round-reniform, cordate or sometimes cuneate 

 at base, obscurely sinuate-dentate or coarsely and sharply or lacini- 

 ately toothed, very rarely 3-lobed : petals rose-colored, 4 to 6 lines 

 long, more than twice longer than the purplish sepals : pedicels 

 spreading (3 to 9 lines long) : pod 12 to 18 lines long by a line wide, 

 attenuate into a very slender style (2 lines long or more), — or in Var. 

 pachystigma, the pod much stouter and broader, with a very short 

 stout style. — Mountains of Plumas County, California ; J. G. Lemmon, 

 Mrs. R. M. Austin, and Mrs. M. E. P. Ames. The root is a small 

 deep-seated tuber. Referred to in the Botany of California under 

 Cardamine paueisecta. 



Draba Montana. Annual, hoary throughout with a rather dense 

 villous pubescence : stem stout, simple or branched, leafy, 3 to 10 

 inches high : leaves rosulate at base, lanceolate, obtusish, entire or
