 vix minoribus. 



Cardamine nivalis, Gillies, in Hook. Bot. Misc. 3, p. 136. 



Hab. Orange Harbour, Fuegia ; both varieties : the latter also from 

 Rio Negro, Patagonia. Andes of Chili, near Santiago, on the snow 

 line ; a dwarf form, in fruit. 



Root manifestly perennial, often tuberous. Stems 2 to 4 inches, or in 

 the larger variety a foot high, sparsely hairy, w % glabrous, at least 

 above, ascending or erect, leafy to the top. Leaves pinnate, petioled, 

 rather fleshy : leaflets ciliate, somewhat angulate-toothed or entire ; the 

 terminal one rounded or reniform and petioled, the lateral sessile and 

 smaller, sometimes minute or wanting; or, in the larger form, the ter- 

 minal obovate and the lateral somewhat similar to it, little smaller, all 

 from half to three-quarters of an inch in length. Flowers 3 lines long. 

 Siliques numerous and much crowded on the short racemes, erect, 

 strict, rather broadly linear, from an inch to an inch and a half in 

 length, almost a line wide ; the valves separating from a broadly mar- 

 gined replum. Seeds oval, about 12 in each cell. 



I cannot think, with Dr. Hooker, that this plant is a form of the 

 variable and cosmopolite Cardamine hirsuta. Ours has a perennial 

 root, and flowers fully as large as those of C. amara; but I most rely 

 for distinguishing it upon the larger and stouter pods; these being 

 fully twice as broad as those of any form of the European or North 

 American C. hirsuta. I scarcely doubt, although my specimen of it 

 is incomplete, that Cardamine cordata of Barneoud, in Gay's Flora 

 Chilena, 1, p. 109, is a variety of C. glacialis. — The C. pratensis var., 

 Fl. Chil. 1, p. 114, is the well-marked C tenuirostris, Hook. & Arn. 

 Bot. Voy. Beech. 1, p. 6.
