TETRADYNAMIA— SILIQUOSA. Dentaria. 18.5 



2 feet high, branched, spreading, leafy. Len^t-es stalked, spread- 

 ing or deflexed, large, undulated and toothed, of a leathery tex- 

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

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

 white. Pouches smooth, the size of Black C\n-rants. 

 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 succeed tolerably if covered up with clean sand.

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

 verging lengthwise, obtuse, deciduous. PeL obovate, 

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

 Stigma obtuse, scarcely notched. Pod sessile, lanceo- 

 late, compressed laterally, tapering upwards ; valves flat, 

 w ithout ribs, narrower than the partition, bursting elas- 

 licaliy from the base, and mostly I'evolute. Seeds ovate, 

 not bordered, inserted alternately in a single row; their 

 stalks dilated and winged; cotyledons accumbent, rather 

 thick. 



Smooth, upright, unbranched kerbs, with fleshy, horizontal, 

 scaly or toothed >-oofs. Leaves mostly alternate, palmate

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

 character in the lanceolate /)o^, and dilated stalks of the 

 seeds, by which this genus may be kept separate from 

 Cardamine, the habit, magnitude, beauty, and peculiar 

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

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

 natural order.
