NATURAL HISTORY OF PLANTS. 



leaves dilated at antheriferous apex, deciduous. Anthers 4, sub- 

 sessile. 1 Hypogynous squamules 4. Germen sessile; ovule 1, 

 ascending, anatropous ; style articulated, at base deciduous ; apex 

 subclavate, sulcate, vertically stigraatiferous. Nut sessile, ventricose, 

 1-seeded. — Erect shrubs ; leaves alternate, coriaceous, partite or en- 

 tire ; flowers in terminal, cylindrical, or capituliform spikes ; bracts 

 1 -flowered, or more frequently 4-flowered ; flowers of each capitulum 

 involucrate {South Africa?) . 



38. Sorocephalus E. Br. 3 — Flowers of Nivenia. Nut shortly 

 stipitate or emarginate at base, ventricose, 1-seeded. — Erect shrubs; 

 leaves alternate rigid, linear or flat, entire or inferior 2-pinnatifid; 

 flowers capitate , capitula 1-6- flowered, collected into capitate ter- 

 minal spikes ; involucre of each capitulum 3-6-leaved imbricate, un- 

 changed in fruiting 4 {South Africa*). 



39. Serruria Salisb. 6 — Flowers (nearly of Nivenia) regular or 

 slightly irregular, hermaphrodite. Perianth tubular ; leaves 4, free, 

 dilated at antheriferous apex. Anthers 4, subsessile, muticous, or 

 shortly apiculate. Hypogynous squamules 4, often minute. Ger- 

 men subsessile ; ovules anatropous, ascending, attached laterally ; 

 style slender, deciduous ; apex clavate or cylindrical, sulcate, verti- 

 cally stigmatiferous. Nut shortly stipitate, ovate, or ventricose, 

 bearded or nearly glabrous, sometimes beaked by style ; 1-seeded. 

 — Shrubs, with aspect of Petrqphila ; leaves alternate ; 7 flowers 

 capitate ; capitula terminal or pedunculate in highest axils ; solitary 

 corymbose, or more frequently collected into a compound capitulum, 

 involucrate, or more rarely naked {South Africa*).

4 This genus is scarcely well distinguished 

 from Nivenia, whereof it is perhaps to be con- 

 sidered as a section (?). It is divided into two 

 sections, thus : — 1. Mischocaryon (Endl.), 

 spike nearly naked ; partial involucres 1-3- 

 flowered; nut shortly stipitate; leaves filiform, 

 entire. 2. Cardiocaryon (Endl.), spikes sub- 



involucrate ; involucres 4— 6-flowered ; nut emar- 

 ginate at base ; leaves flat or filiform, lowest 

 rarely 2-pinnatifid.
