280 THE ALPINE FLORA 



alpine varieties are pretty things for associating with Alys- 

 sum, Aubrietias and early spring flowers, none is really 

 worth cultivation by the side of the Greek Jl. albida, 

 especially in its new double form, whose only fault is its 

 irrestrainable rampancy. 



Jl. alpina (Corbeille d'argent) (PL XIII). A tufted 

 herb, with many creeping, diffuse branches ; leaves 

 greyish, coarsely toothed; flowers pure white, numerous, 

 on lengthy spikes. April-August in cool and rocky parts 

 of the limestone formation (5oo-i5oo m.). 



Jl. arenosa: a biennial, not forming a sward, with slen- 

 der, erect, branching stem; radical leaves deeply pinnatifid; 

 rose or violet flowers, fairly large. May-September in 

 rocky and cool positions of the north and central Jura. 



A. bellidifolia (PJ. XIII). Tufted plant; leaves glossy, 

 oblong-oval, entire or dentate; flowers milk-white, nume- 

 rous, grouped in a stiff panicle. June-July. Moist places 

 in the Alps from 1000 to 2000 m. Will grow in cool parts 

 of the rockery. 



Jl. pumila differs from it in hairy leaves, and a much 

 more squat habit. Native of the Alps (25oo-3ooo m.). 



Jl. cxrulea differs from bellidifolia in a stem hardly ex- 

 ceeding 4 in.; radical leaves terminated by three teeth; 

 small flowers with bluish, caducous petals. July- August 

 among the stones in the high Alps (2400-3000 m.).
