TETRADYNAMIA— SILIQUOSA. Dentaria. 185 



2 feet high, branched, spreading, leafy. Leaves stalked, spread- 

 ing ordeflexed, large, undulated and toothed, of a leathery tex- 

 ture ; the lowermost somewhat lyrate ; the rest roundish, acute. 

 Clusters terminal, collected into dense panicles. Fl. large, 



. white. Pouches smooth, the size of Black Currants. 



This is. now become a frequent culinary herb. Its young shoots, 

 which are very hardy, are earlier than Asparagus, and nearly as 



, good. They are best raised under tall earthen pots perforated 

 at the top, but sucqeed tolerably if covered up with clean sand.

Cal. equal at the base, erect ; leaves ovate-oblong, con- 

 verging lengthwise, obtuse, deciduous. Pet. obovate, 

 obtuse, horizontal, with erect claws shorter than the ca-

 shaped, erect. Germ, oblong. Style short and thick. 

 Stigma obtuse, scarcely notched. Pod sessile, lanceo- 

 late, compressed laterally, tapering upwards ; valves flat, 

 without ribs, narrower than the partition, bursting elas- 

 tically from the base, and mostly revolute. Seeds ovate, 

 not bordered, inserted alternately in a single row ; their 

 stalks dilated and winged ; cotyledons accumbent, rather 

 thick. 



Smooth, upright, unbranched herbs, with fleshy, horizontal, 

 scaly or toothed roots. Leaves mostly alternate, palmate

We are much obliged to Prof. DeCandolle, for finding a 

 character in the lanceolate j-wrf, and dilated stalks of the 

 seeds, by which this genus may be kept separate from 

 Cardamine, -the habit, magnitude, beauty, and peculiar 

 kind of root, marking it so distinctly. Some of the spe- 

 cies are among the finest alpine plants, at least of this 

 natural order.
