130 CRUCIFER.E. 



Stanleva. (Plate 05.) Claws of the petals connivent into a tube ; the 

 linear sepals spreading. Silique nearly terete or quadrangular. 

 Flowers yellow or greenish. 



Warea. (Plate 66.) Claws of the (white or rose-purple) petals spread- 

 ing. Silique compressed, the valves nearly flat, 1-nerved. 



Ser. II. SiLicuLosa:. — Silicle (rounded, or not much long- 

 er than broad) opening by valves. Cotyledons plane, 

 not longitudinally plicate nor spirally convolute. 



Tribe III. ALYSSINEiE. — Silicle with a broad partition (or rarely 

 none) which is parallel with the flat or convex valves. Cotyledons broad, 

 accumbent against the ascending radicle (o=), parallel with the partition. 

 # Silicle compressed. Seeds on free funiculi. 

 Selenia. (Plate 67.) Silicle oval, flat, subulate with the long style, 



many-seeded. Seeds orbicular, surrounded by a wing. 

 Draea. (Plates 68, 69.) Silicle elliptical, oval, or linear-oblong, com- 

 pressed, many-seeded. Seeds wingless. 



• # Silicle globose-inflated. Funiculi partly adnate. 

 Vesicaria. (Plate 70.) Valves of the several-seeded silicle hemispherical. 



Tribe IV. SUBULARIE^E. — Silicle oval, turgid, with a rather 

 broad partition, the cells several-seeded. Cotyledons bent transversely be- 

 low the middle and incumbent on the ascending radicle. 



Subularia. (Plate 71.) Silicle somewhat flattened contrary to the par- 

 tition, the convex valves rather boat-shaped. Leaves all radical, 

 subulate. 



Tribe V. SENEBIEREiE. — Silicle compressed contrary to the very 

 narrow partition, didymous ; the globular-ventricose valves closed or nearly 

 so, 1-seeded. Cotyledons as in Tribe IV. 



Senebiera. (Plate 72.) Cells of the silicle rugose-reticulated, separat- 

 ing entire. Flowers minute. 



Tribe VI. LEPIDINE2E. — Silicle compressed contrary to the very 

 narrow partition ; the valves strongly boat-shaped or carinate. Cotyledons 

 plane, incumbent (rarely accumbent) on the ascending radicle. 



Lepidium. (Plate 73.) Seeds solitary in each cell : funiculi free. 



Ser. III. Lomentaceje. — Silique or silicle transversely 2- 

 several-celled, and articulated. 

 Tribe VII. CAKILINE/E. Cotyledons plane, accumbent. 

 Cakile. (Plate 74.) Silicle 2-jointed ; the joints 1-celled, 1-seeded. 

 Seed suspended tn the lower, erect in the upper cell.
