38 NATURAL HISTORY OF PLANTS. 



2. Osbeckia L.' — Flowers nearly of Melastoma,A, 5-merous or 

 very rarely 6, 7-merous. Stamens 8-14, 2-seriate, either very 

 slightly unequal, or the oppositipetalous a little shorter {Dissotis,'^ 

 Tristemma^); the connective of all or of the longer more or less 

 produced under the anthers, or very slightly (Nerophila),* internally 

 at the base 2-tuberculate {EuosbecMa,^ Antherotoma,^ Tristemma) or 

 appendiculate (Dissotis), sometimes destitute of tubercles (Guyonia'^) ; 

 cells acute at apex, poricidal, or more widely truncate ; pore larger 

 oblique {Anther otoma): Fruit capsular, oftener setose at vertex, 

 4, 5-valvate; seeds, &c. of Melastoma. — Shrubs or herbs, sometimes 

 annual (Nerophila) ; habit various ; leaves of Melastoma ; flowers 

 terminal, or more rarely axilar (Guyonia), solitary or cymose or 

 glomerate, sometimes (Antherotomai Nerophila, Tristemma) more or less 

 fully involucrate with bracts.' {Trap. Asia and Africa cant, and ins.^) 



3. Dichaetanthera Endl."*— Flowers nearly of Melastoma, 4, 5- 

 merous; sepals broad concave, much contorted or imbricate. Petals 

 4, 5, retuse. Stamens 8-10, nearly of Melastoma, connective of the 

 larger longer produced and longer appendiculate ; aristse 2, slender, 

 long subulate. Fruit capsular, 4, 5-valved at apex; seeds nearly 



straight or more or less eochleate Shrubs; branches nodose ; leaves 



petiolate, 3-nerved; flowers in terminal 2-chotomous cymes; bracts
