416 NATURAL HISTORY OF PLANTS. 
cylindrical, terminal or lateral, strobiliform spikes ; bracts 2-flowered, 
bractlets 2 to superior flowers (Australia). See p. 390. 
22. Dryandra R. Br.'—Flowers regular, hermaphrodite ; perianth 
leaves equal, free or connate at base, dilated at antheriferous apex. 
Anthers 4, subsessile, shortly apiculate.2 Hypogynous squamules 4. 
Germen sessile; ovules 2 collateral, after impregnation coherent and 
usually forming a spurious dissepiment; style slender, often arti- 
culated at base, usually straight ; apex cylindrical or clavate, smooth 
or suleate, stigmatiferous. Follicle woody; dissepiment membra- 
nous free 2-fid, or 0; seeds winged at apex.—Small trees or shrubs ; 
branches scattered or umbellate ; leaves alternate coriaceous, ser- 
rated, lobed or pinnatifid, more rarely entire; flowers in terminal 
or lateral, sessile involucrate capitula (South Australia’). 
23? Hemiclidia R. Br.‘—“ Flowers regular, hermaphrodite. Pe- 
rianth 4-fid ; lobes concave antheriferous. Hypogynous squamules 4. 
Germen 1-celled; testee coherent into a dissepiment; dissepiment 
arachnoid simple (not separable into 2 layers), separating with the 
abortive ovule from the other on ripening. Follicle subcrustaceous, 
bearded all over. Seed 1, ventricose wingless——A shrub; leaves 
and habit of Dryandra ; involucre imbricate ; receptacle of capitulum 
flat’ (Australia’). 
III. PERSOONIEZ. 
24, Persoonia Sm.—Flowers regular hermaphrodite.’ Perianth 
4-merous, rarely gibbous; leaves free or connate to a variable 
height ; margins valvate or slightly involute. Stamens inserted 
half way up perianth leaves; filaments filiform, usually short; 
anthers linear exserted; apiculated by produced connective, or sub- 
muticous. Hypogynous glands 4, free. Germen stipitate or sessile ;
