422 NATURAL HISTORY OF PLANTS. 
leaves dilated at antheriferous apex, deciduous. Anthers 4, sub- 
sessile’ Hypogynous squamules 4. Germen sessile; ovule 1, 
ascending, anatropous; style articulated, at base deciduous ; apex 
subclavate, sulcate, vertically stigmatiferous. Nut sessile, ventricose, 
1-seeded.—Erect shrubs; leaves alternate, coriaceous, partite or en- 
tire; Howers in terminal, cylindrical, or capituliform spikes ; bracts 
1-flowered, or more frequently 4-flowered ; flowers of each capitulum 
involucrate (South Africa’). 
38. Sorocephalus R. Br.i—Flowers of Mivenia. 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’ (South Africa’). 
39. Serruria Sariss.:—Flowers (nearly of Mivenia) 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 Petrophila; leaves alternate ;’ 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 (END1.), 
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.
