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 

 (Soitt/i- Western Africa). See p. 390. 



10. Adenandra W. 1 — 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. — Erect 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) 2 sessile at apex of twigs or 

 subumbellate or racemose; pedicelsv 2 -bracteolate (South Africa*).
