GENERA. 



1. Leptolaena Dup.-Th. — Flowers hermaphrodite ; receptacle 

 rather convex. Sepals 3, cortorted or much imbricated. Petals 5, 

 free, contorted. Stamens 10, inserted inside, slightly above the base 

 of urceoliform shortly cylindrical disc, obscurely crenate at apex ; 

 filaments otherwise free ; 5 oppositipetalous shorter ; anthers in- 

 trorse versatile ; connective rather thick ; cells 2, longitudinal clefts 

 often confluent at apex. Germen superior, 3-locular ; cells oppositi- 

 petalous ; style elongated stigmatiferous at apex, obtuse 3-lobed, 

 much dilated. Ovules in each cell 2, inserted in internal angle, 

 collaterally descending ; micropyle extrorse superior. Fruit dry 

 (indehiscent ?) by abortion 1-locular 1-spermous. Seed descending or 

 laterally affixed, subpeltate ; micropyle inwardly lateral ; testa 

 glabrous coriaceous ; albumen fleshy or subcorneous ; embryo 

 parallel to hilum ; radicle superior cylindrical ; cotyledons foliaceous, 

 base cligitinerved, subplane or undulate. — Small trees, leaves alter- 

 nate subentire coriaceous reticulate penninerved ; stipules lateral 

 caducous ; flowers (small) in racemes (terminal or axillary to upper 

 leaves) much ramified and cymose; each involucel calyciform sacciform 

 suburceolate, 6-denticulate at apex, persistent and accrescent round 

 fruit, rather fleshy, stipitate {Madagascar). See p. 22S. 



2. Sarcolsena Dup.-Th. 1 — Flowers nearly of Leptolana ; stamens 

 co . Capsule 3-locular; cells 1, 2-spermous. — Elegant trees or small 

 trees, sometimes climbing ; leaves alternate, usually entire coriaceous, 

 impressed in lines above, from induplicate racemose vernation as if 

 3-5-nerved or sometimes small submembranous unequal-crenate. 

 Stipules small or oftener wide conical caducous. Inflorescence of 

 Leptolcena, many flowered, or sometimes 1 few-flowered terminal,
