plant which he has labeled as growing at 5000 ft. altitude 

 is seldom, if ever, found at a lower elevation than 8500 

 ft., nor is any Aquilegia known to exist in the Wasatch 

 Mountains at 5000 ft. altitude, for that altitude is reached 

 before you touch the base of the mountains. 



This low altitude species, above described, may take 

 the name of jiavescens, since it was considered belonging 

 to the species, rather than to make a new name. It is 

 always found in cold springs or streams at low elevations. 

 This is my number 1348 and to it I also refer Watson's 

 No. 36. 



Aquilegia c^rulea var. calcarea. 



No. 5312a. May 28, at the head of the canon above 

 Cannonville, Utah, 7000° alt., in very compact and barren 

 clay, among trees of Piniis -ponder osa. 



No. 5312am. Same locality as above. 



This variety has the habit of the typical form, but the 

 leaves are reduced to three clusters of three leaflets each, 

 and these again cleft, parted or lobed; leaflets only 6" 

 long, and as wide, glaucous, minutely notched at the 

 rounded apex, faintly nerved, thick, overlapping each 

 other, and so the whole leaf seeming to be composed of 

 three nearly round clusters of leaflets, the whole not over 

 an inch in diameter; petioles very glandular-hairy, as well 

 as the stems and peduncles; flowers about half the .size 

 of typical ccBrulea; sepals blue -purple, oval, acutish, 6" 

 long by 4" wide, abruptly contracted at the insertion; 

 petals nearly square but rounded at apex, 4" long, pinkish, 

 about equalling the stamens; anthers oval, y^" long; 

 stem leaves absent, but there is one 3-lobed bract at the 

 base of the lowest peduncle, 6" long; spurs about twice 

 the sepals, with abortive gland at the tip; leaf-sheaths 

 very thick and fibrous on the top of the root. 



This appears to be a well-defined new species, but in
