io THE FLORA OF THE ALPS 



A. Spur of the petals rolled up at the apex: Our 

 English Columbine, A. vulgaris, L., is common through- 

 out Switzerland and Pyrenees. A variety, A. atrata, 

 Koch, with dark violet flowers, is found in bushy places 

 in the Alps. A. Hcenkeana, Koch, with very large violet 

 flowers, is a native of Carinthia, Carniola, and Tirol. 



B. Spur of petals straight or slightly curved: A. 

 alpina, L., resembling A. vulgaris, but with larger 

 flowers, is rare in bushy places in Switzerland, Dauphiny, 

 and Pyrenees. A. pyrenaica, DC. (PI. 4), with a slender 

 spur and smaller leaves, is a native of Pyrenees and 

 Southern Switzerland. A. Einseleana, F. Schultz, with 

 viscid stem and hairy spur; and A. thalictrifolia, Sch. 

 and K., with glabrous spur and linear-lanceolate leaf- 

 segments, are rare plants in Tirol, and the former also in 

 Carinthia.

Flowers irregular; sepals and petals coloured and 

 spurred. 



D. datum, L., with azure-blue sepals, rough grey 

 petals with a long narrow spur, and 3-4 carpels, is 

 found locally in dry sub-alpine meadows in Switzerland 

 and Pyrenees; and D. tirolense, Kern., with dark blue 

 sepals and petals and narrower leaf-segments, in Northern 

 Tirol. Our English Larkspur, D. Consolida, L., with one 

 carpel, is a cornfield weed in Switzerland ; and several 

 other species in Pyrenees.
