40. Heliophila L. 1 — Sepals equal or subequal at base. Stamens 6 ; 

 lateral sometimes with a tooth at base. Siliqua very variable in form, 

 sessile or stipitate, indehiscent or dehiscent ; edges straight or sinuate 

 constricted between seeds ; valves flat, 1-3-ribbed ; septum hyaline ; 

 style short, robust or elongated ; apex stigmatose, discoidal subentire 

 or 2-lobed. Seeds few or co, t-2-seriate, immarginate or winged; 

 embryo fleshy elongated ; cotyledons transversely 2-plicate, incumbent 

 or accumbent on cylindrical radicle. — Herbs, annual or perennial at 

 base, glabrous or pubescent, more rarely branching undershrubs ; 

 leaves entire dentate sinuate pinnatisect or multifid ; flowers 2 

 racemose ; pedicels usually very slender, ebracteate 3 {South Africa''). 



41? Chamira Thunb. 5 — Sepals unequal at base; lateral saccate. 

 Stamens 6, free. Siliqua very shortly stipitate, oblong compressed ; 

 valves rather flat striate ; style subulate. Seeds few, 1 -seriate, ovate- 

 compressed ; testa rather thick, soft ; embryo rather fleshy (coloured) ; 

 cotyledons transversely 2-plicate ; radicle slender. — A glabrous an- 

 nual herb; inferior leaves subopposite sessile; superior alternate 

 smaller cordate petiolate ; flowers 6 few, in terminal racemes {West 

 of South Africa}). 



c. BEASSICINE.E. — Cotyledons usually incumbent. 



42. Brassica T. — Sepals erect or spreading, equal or lateral more 

 often saccate at base. Petals unguiculate. Stamens G, 4-dynamous ; 

 filaments free toothless. Hypogynous glands 4, superposed to petals.
