narrowed below, entire or minutely toothed. Flowers numerous, minute, in 

 slender, terminal or leaf-opposed racemes. Silicules didyraons, each valve 

 subglobose, reticulate-wrinkled. — S. linoides, DC. ; Harv.et Sond. Fl. Cap. 

 i. 27. 



Mozamb. Distr. Zambesi, Peters {Klotzsch in Peters' Mossamb.) ; Europa Island, 

 Mozamb. Channel, Spekel 



This appears to be a widely -spread coast species, occurring about Capetown, in Mada- 

 gascar, islands of the Chinese Sea, and N.E. Australia. 



S. didyma, Pers., differing from S. integrifolia in having prostrate, more or less hairy 

 stems and leaves all pinnatipartite, is a very common and widely dispersed weed, which may 

 be expected as a waif upon the shores of tropical Africa. S. Coronopus, DC, with scarcely 

 emarginate silicules, also prostrate, with pinnatifid leaves and deeply wrinkled fruits, is likely 

 to occur in waste places. 



18. CRAMBE, Linn.; Bentb. et Hook. f. Gen. PI. i. 98. 



Sepals more or less spreading. Silicules separated by an articulation into 

 two articles ; the upper globose, 1-locular, 1-seeded, with a sessile stigma ; 

 the lower minute, seedless and pedicel-like. Seed globose, radicle incum- 

 bent on the conduplicate cotyledons. — Glabrous glaucous or pilose herbs, 

 sometimes shmbby. Leaves lyrate or toothed. Racemes elongate, simple 

 or panicled, ebracteate. Flowers white. 



A genus of 10 to 20 species, confined chiefly to Europe, Western Asia, and the Atlantic 

 Islands. 



Stem and leaves more or less hispid-pilose 1. C. hispanica. 



Stem and leaves glabrous, glaucescent 2. C. sinuato-dentata. 



1. C. hispanica, Linn. ; DC. Syst. Veg. ii. 655. An erect herb, more 

 or less liispid-pih)se below, attaining 1-4 ft. Lower leaves lyrate or reduced 

 to the large rounded or cordate, terminal lobe, hispid. Cauliiie ovate or lan- 

 ceolate, petiolate or narrowed below, unequally dentate. Racemes panicled ; 

 the lateral axillary ones usually considerably shorter than the primary axis. —

Nile Ijand. Abyssinia, Schimper ! 

 A Mediterranean species. 



2. C. sinuato-dentata, Hochst. in Schimp. FL Abyss. A slender, 

 erect, glabrous, glaucescent herb. Cauline-leaves ovate-lanceolate or lanceo- 

 late, acute or subacute, toothed ; the lower petiolate. Racemes simple or 

 forked, elongate. 



Nile Iiand. Abyssinia, Schimper ! 



This plant appears different from any other species which I have seen. It is probable 

 that the racemes become panicled in more luxuriant specimens. 



19. ENARTHROCARPUS, Labill. ; Benth. et Hook. f. Gen. PI. i. 99. 



Sepals erect, equal at the base or the two lateral saccate. Siliquas elon- 

 gate, curved, somewhat compressed, separated by an articulation into two 

 indehiscent articles; the lower article shorter, with connate valves, 1-4- 

 seeded, seeds pendulous ; upper article 3-6-scc(le(l, seeds erect. Radicle
