BOTANY. 
Caltha LEPTOSEPALA, DC. Stems (3'-l° liigli) erect, 1-flowered; leaves 
radical, ovate-cordate, obscurely creiiate ; carpels beaked with tlie sliort 
recurved style ; sepals white, or tinged with blue. — Su])alpiiie swamps, 
Colorado to California and Washington Territory. Found in the East Hum- 
boldt and Clover Mountains, Nevada, and in the Wahsatch, Utah ; 9-10,000 
feet altitude ; July-September. (31.) 
Trollius laxus, Salisb. Sepals dull greenish- white or yellowish. New 
Hampshire to Delaware and Michigan, and on the eastern slope of the Eocky 
Mountains, from Colorado to latitude 55°. Uinta Mountains, Utah ; 9,000 
feet altitude ; July, August. (32.) 
Aquilegia Canadensis, L., Var. foemosa, Torr. Tall, 2-3° high, 
nearly naked above, the hmb of the petals 1-2" long, the spurs never greatly 
exceeding the reflexed sepals ; styles shorter than the stamens. — The parts 
of the flower of this prevalent and perhaps distinct western Aquilegia are so 
variable that A. truncata, Fisch. & Mey., {A, Californica, Lindl. and A. 
exi?ma, Van Houtte,) can with difficulty l)e separated from it. California to 
Alaska; not unfrecpient on mountain streams in Nevada, at an elevation of 
6-7,000 feet, but not seen in Utah. June-September. (33.) 
A subalpine form has the stem nearly simple, few-flow^ered ; uppermost 
leaflets entire, oblong or oval ; sepals oval, equaling or exceeding the spurs. 
p:ast Humboldt Mountains, Nevada ; 8-9,000 feet ; July, August. (34.) 
Aquilegia flavescens. Spurs more or less incurved and tipped, shorter 
than the spreading or reflexed oval or oblong-ovate sepals; Hmb large (3-4" 
long) and dilated; styles nearly equaling the long exserted stamens. 2-3° 
high ; glabrous, witli the carpels and peduncles pubescent ; flowers yellow, 
the sepals (j-l' long) frequently tinged with scarlet. Wahsatch and Uinta 
Mountains, Utah; 5-7,000 feet altitude ; May-July. It has been collected 
also by Lyall on the the Oregon boundary, and by Bourgeau in the Rocky Moun- 
tains, and referred provisionally to A. Canadensis. A comparison of a large 
number of specimens leaves no doubt that it is distinct. (35.) A more alpine 
form has much smaller leaves and flowers, with the stem sometimes subpu- 
l)escent. (30.) 
Aquilegia c.erulea, James. Spurs straight, very slender, 2' long; 
sepals rliomboid-ovate, longer than the limb ; stamens and styles shorter than 
the corolla.— Stem 2° high; glal)rous, few-flowered; flowers 3' in diameter, 
white in all the speciinens of the collection or with the sepals very lightly tinged
