5G BOTANY. 
tufted root; petioles 1-4 inches long, leaves 3-5 parted, each segment 
lanceolate-cuneate and trifid; involucre sessile, its leaflets 3-5 cleft; car- 
pels tailless, compressed, oval, and glabrous. Entire plant more or less 
densely covered with gray hairs; flowers white. Found in America most 
commonly from Canada north, but growing in Colorado on alpine summits, 
where, according to Mr. J. M. Coulter, it has been found at an elevation of 
13,500 feet. (102 a) 
ANEMONE CYLINDRICA, Gray. SS Wiaiew. Springs, Ariz.; rare there and 
probably by seme accident introduced. (247.) 
_ Myosurus minimus, L.—Colorado; altitude, 8,000 feet and upwards; 
specimens much dwarfed. (169.) 
RaNUNCULUS AQuaTILis, L., var. staGNATILIS, DC.—Denver. ' Flowers 
almost as large as £2. Purshii, Richardson, var. trichophyllus, Chaix. ‘Twin 
Lakes, Colo., at 9,500 feet altitude. (113 and 115.) 
RanuncuLus Fruammuta, L., var. repTans, Gray.—Colorado. (172 
and 173.) 
RanuncuLus nypRocHarorwes, Gray. (Pl. Thurb. p. 506.)—Glabrous 
throughout, flowering branches erect, numerous stolons branching off in all 
directions and rooting; lower leaves heart-shaped, and entire, or nearly so; 
petioles 2-3’ long, expanding and sheathing at the base; upper leaves 
lanceolate; peduncles about as iong as the upper leaves, from opposite the 
axils of which they arise; sepals round, petals 3’, tapering into a claw, 
which has a conspicuous gland below a small sinus; stamens about 25 ; 
carpels 15-20, forming a head 2-3” in diameter. Willow Springs, Ariz., 
growing in water at a temperature of 50° Fahr. at an elevation of 7,202 
feet. A most interesting species, which I believe has not hitherto been 
taken so far north. (217.) 
Rayuncutus Cympauaria, Pursh—In Colorado grows everywhere in 
low moist ground, evincing, however, a marked choice for alkaline soils, but 
still flourishing in the freshest of snow water; altitude, 5,000.to 10,000 feet. 
From Saguache, in the San Luis Valley, we have a form with an erect, 
stout scape, bearing three or four flowers, having thicker and larger leaves, 
and manifesting little or no tendency to produce stolons. 
At Santa Fé, N. Mex., I collected it (10) at what I presume is the
