922 CARDAMINE. [CLASS XV, ORDERir 



1. D. hulbi'fei'a, Linn. (Fig. 1065.) Bulhiferous Coral-root. Stem 

 simple ; leaves alternate, the lower ones pinnated, the upper lanceolate 

 serrated, mostly all bearing axillary bulbs. 



English Botany, t. 309.— English Flora, vol. iii. p. 186.— Hooker, 

 British Flora, ed. 4. vol. i. p. 251. — Lindley, Synopsis, p. 25. 



Root With creeping fleshy branches, bearing thick tooth-like scales 

 Stem erect, simple, round, smooth, about two feet high. Leaves alter- 

 nate, petiolated, pinnatifid, the leaflets lanceolate, or ovate lanceolate, 

 the two upper ones mostly united at the base, more or less deeply 

 toothed, sometimes almost entire, the upper leaves simple, lanceolate, 

 and all of them generally bear in the axis a purple fleshy scaly bulb. 

 Injiorescence a terminal corymbose cluster of large handsome purple 

 flowers, mostly imperfect. Cahjx of four oblong erect pieces, with a 

 thin membranous usually torn margin. Petals oblong, tapering at the 

 base, spreading about half an inch long. 



Habitat. — Moist shady places, rare. Near Mayfield, Sussex ; in 

 the Old Park Wood, near Harefield, Middlesex; Tonbridge Wells . 

 near Duppliu, and Banks of the Esk below Dalkeith. 



Perennial ; flowering in April and May. 



This plant is remarkable, from its bearing in the axis of its leaves 

 fleshy scaly bulbs, which, as they ripen, fall to the ground, and put out 

 from the base roots, which absorbing nutriment put forth a stem, 

 and thus anew plant is produced in the same manner that it would be 

 by seeds ; but as by this means the plant propagates itself, seeds are 

 not formed, and the siliqua are imperfect. Other species of this genus 

 bear bulbs in the same manner, for which reason the name of bulbifera 

 is not a very good one, as it seems to imply a distinction which is not 

 its own. 



GENUS XXVIII. CARDAMI'NE.— Linn. Bitter-cress. 



Nat. Ord. Crucif'er^. Juss. 



Gen. Char. Siliqua linear, lanceolate, valves flat, ribless, separating 

 elastically. Seeds ovate, attached by a slender cord. Cotyledons 

 flat, accumbent.— (See Fig, 1, p. 871.)— Name from Jca^Jta, 

 the heart ; and ^<x.(x(x,co, to strengthen, or fortify ; in allusion to the 

 supposed strengthening properties of some of the species. 

 * Leaves simple. 

 1. C. hellidi* folia, Linn. (Fig. 1066.) Daisy-leaved Bitter-cress. 

 Leaves smooth, thickish, the radical ones ovate, petiolate, entire, those 

 of the stem nearly entire, or sub-trilobate ; siliqua erect; stigma nearly 

 sessile.
