40 NATURAL HISTORY OF PLANTS. 



anthers inflexed in bud, 1 -porous at apex, pore small or larger, con- 

 nective below cells more or less (sometimes very little) anteriorly 

 elongate, curved, and furnished at base with 2 appendages very various 

 in form and size. Germen quite or to a large extent free, glabrous or 

 variously clothed, conical or hemispherical at apex. Fruit capsular, 

 2-5-celled; seeds do , oftener punctulate, or oftener curved or cochleate, 

 or straight, oblong or ovoid {Bucquetia,^ Pyramia,^ Comolia, Svitramia,^ 

 Meissneria,^ Tulasnea^), sometimes curved or subcochleate (Poteran- 

 thera^). — Shrubs, undershrubs or herbs ; leaves opposite, rarely verti- 

 cillate, entire or serrate or dentate, 3-7-nerved ; flowers solitary or 

 oftener in simple or compound cymiferous racemes.' (Both trop. 

 Americas,^) 



6 ? Pterogastra Naud.^ — Flowers nearly of TihoucUna, 4, 5- 

 merous ; receptacle externally furnished with vertical echinate ribs. 

 Stamens 8-10, unequal; anthers subulate, connective of the greater 

 (alternipetalous) longer produced^ furnished with a short (or 0) appen- 

 dage. Germen free, 4, 5-celled, setose at vertex; style slender, 

 slightly or not dilated at apex. Capsule 4, 5-valved ; seeds curved or 

 cochleate roughish. — Annual herbs, 2-chotomously ramose ; twigs 4- 

 gonal; leaves opposite, very entire membranous, 3-5-nerved; flowers 

 axillary solitary or ramoso-3-chotomo-cymose.^° (Trop. America}^)
