74 SUB-ALPINE PLANTS 



Flowers white, rather large. Anthers violet. Pods erect, twice as 

 long as the stalk. 



Damp, stony places in the mountains, especially by streams. 

 July. 



Distribution. — Basses-Alpes, and both French and Italian Mari- 

 ^ time Alps, Piedmont, Tyrol, Spain. In Switzerland, near Poschiavo. 



Easily cultivated in wet, stony places, but not often seen in 

 gardens, though a very distinct plant. It does not object to the 

 shade of trees or rocks. 



Cardamine latifolia Vahl. 



Similar in habit and culture to the last species, from which it 

 differs in having lyrate leaves with 3-7 large leaflets which are 

 shortly stalked ; the terminal leaflet is larger and suborbicular. 

 The flowers are lilac and the anthers yellow. The pods are erect, 

 more spreading, and on longer stalks than in A. asarifolia. 



Springs and rivulets in the lower mountains (at about 3500 feet 

 in the Eastern Pyrenees). May to July. 



Distribution. — Pyrenees, Corbi^res, Spain, N. Italy. 



Cardamine praiensis L. (Cuckoo-flower), C. amara L. (flowers 

 white, anthers violet), C. impatiens L., C. flexuosa With, (with 

 zigzag stem), are four British species spread throughout the plains 

 of Switzerland, and often seen in damp mountainous woods or 

 meadows up to 5000 feet, both in the Alps and Eastern Pyrenees. 



Cardamine bulbifera Crantz (Dentaria bulbifera L.). Coralroot. 



Rootstock scaly, whitish. Stem weak, 1-2 feet high, bearing 

 several leaves, often with a small ovoid bulbil at their axil ; lower 

 leaves pinnate with 5 or 7 segments, the upper ones with fewer 

 segments or quite undivided ; all segments lanceolate, entire, or 

 toothed, 1^2 inches long. Flowers few, rather large, bright lilac, 

 rarely white. The pod is seldom formed, as the plant is propagated 

 by the axillary bulbils falling to the ground and growing. 



Woods and shady places in the plains and hills. April to June. 



Distribution. — Spread over Continental Europe from Scandinavia 

 and the north of France to the Caucasus. In England in some of the 

 ' home counties.' 



Cardamine pentaphylla R. Br. [Dentaria digitata Lamk.). 



This is a smaller plant with no bulbils. The leaves are digitate 

 and divided into 3-5 leaflets, which are oblong-lanceolate and 

 toothed irregularly. Flowers rose or lilac. Siliqua erect, spreading. 

 Rootstock fleshy, scaly. 



Figured in Curtis's Bot. Mag., tab. 2202 (1821).
