464 NATURAL HISTORY OF PLANTS. 
form entire, sinuate or 5-lobed glandular disk. Calyx 5-partite ; 
lobes ovate-acute, or aristate, imbricated. Petals obovate unguicu- 
late glabrous, inwardly from base to middle thickened-canaliculate, 
imbricated or more rarely contorted. Stamens 10, of which 5 are 
alternipetalous, fertile glabrous; filament inserted without disk, 
usually subperigynous, free; anthers 2-locular, introrsely rimose, 
glandular terminate; oppositipetalous 5, reduced to staminodes, in- 
cluded in canaliculate petals or recondite adnate. Carpels 5, oppo- 
sitipetalous, or more rarely 2-4; ovary free, naked at apex or ter- 
minating dorsally in glandular thickening; styles 5, free at base, 
afterwards coalescing in erect column, capitellate-stigmatiferous 
5-lobed at apex ; ovules 2, subcollateral or subsuperposed descending ; 
micropyle extrorse superior. Fruit cocci 5, compressed rugose, 
corniculate at apex; endocarp solute, finally 2-valved. Seeds in each 
coccus 1, 2; embryo exalbuminous fleshy.— Ericoid glandular- 
punctuate shrubs; branches slender; leaves alternate linear, very 
acute, ciliate at margin, serrulate or smooth; flowers solitary at 
apex of twigs or scantily cymose, bracteolate ; bractlets adpressed 
(South-Western Africa). See p. 390. 
16. Adenandra W.'—Flowers nearly of Coleonema; receptacle 
more or less cupuliform. Petals subsessile naked. Stamens 10, of 
which 5 are sterile, opposite petals, not recondite ; the fertile termi- 
nating in glandular stipitate anthers. Germens 2-5, bearing stipitate 
glandules ; styles coalescing in short sulcate curved column, discoid- 
stigmatiferous 5-lobed at apex. Cocci glandular-muricate, obtuse 
or corniculate.—KErect ramified glandular-punctuate shrubs; leaves 
alternate, sometimes imbricated, or more rarely opposite subsessile 
small coriaceous, entire or callose at margin and apex ; petioles some- 
times 2-glandular ; flowers (rather large)’ sessile at apex of twigs or 
subumbellate or racemose; pedicels 2-bracteolate (South Africa’).
