NATURAL HISTORY OF PLANTS. 



Petals rather long-unguiculate. Stamens 6, free, toothless, 4-dynam- 

 ous. Disk of variable form ; placentary glands compressed- 3- 

 gonous or arcuate-concave. Siliqua 2-jointed indeliiscent ; lower 

 joint stipitate obpyramidal, aspermous or 1-seeded (Didesmus, 1 

 Otocarpus 2 ), sometimes 2-4-seeded (Cordj/loca?pus 3 ) ; seeds 1 -seriate 

 descending; upper joint ovoid or cylindrical, rostrate, costate oralate 

 tuberculate, more rarely broadly obcuneate-2-horned {Otocarpus), 

 usually 1-seeded; seed ascending; funicle short; embryo often 

 coloured; cotyledons conduplicate or 2-plicate at apex. — Erect 

 branching herbs, pubescent or pilose ; flowers 4 in elongated simple or 

 branched racemes ; pedicels slender, when fruiting thickened, erect 

 or patent {South Europe, West Asia, North Africa 5 ). 



Gl. Muricaria Desvx. 6 — Sepals equal at base suberect. Petals 

 unguiculate. Stamens free, 4-dynamous. Siliqua short crustaceous, 

 2-jointed indeliiscent ; lower joint very short seedless ; upper 

 subglobose or ovoid, echinate, tuberculate or rostrate, 1-seeded ; 

 style conical or subcylindrical compressed ; 7 stigmatose apex more or 

 less capitate. Seed descending oblong compressed; embryo coloured ; 

 cotyledons conduplicate. — Branching herbs, erect or procumbent ; 

 leaves pinnatilobate ; flowers 8 in racemes, at first contracted corym- 

 biform, finally elongated {North Africa 9 ). 



62. Crambe T. 10 — Sepals equal at base, spreading. Petals 4, 

 more or less long in the claw. Stamens 6, free ; longer sometimes 

 possessing a tooth. Grermen subclavate, lower joint linear cylindrical ; 

 ovule rudimentary ; upper joint ovoid ; ovule descending ; stigma 

 sessile. Fruit 2-jointed subdrupaceous, finally dry indeliiscent ; lower 

 joint stipe-like, aspermous; upper subglobose 1-seeded; seed
