Winter-Cress. Yellow Rocket. 



Calyx almost equal at the base (yellowish); the lateral 

 sepals more or less gibbous at the base, often with a cor- 

 nute appendage near the apex. Petals unguiculate with a 

 broad and plane claw, the lamina rounded. Stamens strong- 

 ly tetradynamous : filaments subulate, toothless. Glands 

 6, two of them larger and very prominent, one at the base 

 of each pair of long stamens. Ovary linear : style short : 

 stigma two-lobed. Ovules pendulous, forming a single se- 

 ries in each cell. 



SiLiauE linear, slightly compressed, but quadrangular, the 

 cross section rhombic, two-valved ; the valves prominently 

 carinate-one-nerved, the placentas or edges of the rephun 

 also a little salient : partition nerveless ; the areolae oblong 

 and very irregular, bounded by sinuous lines. Seeds nu- 

 merous, pendulous on free filiform funiculi, forming a single 

 row in each cell, nearly or quite as broad as the partition, 

 oval, a little compressed, not margined ; the testa minutely 

 punctate. Cotyledons plane, thickish, parallel with the 

 partition, accumbent against the radicle, which ascends on 

 the side remote from the placenta.

 ing leafy stems, and lyrate-pinnatifid leaves, mostly auricu-
