410 NATURAL HISTORY OF PLANTS. 



and bracts ciliate ; flowers in contracted compound axillary cymes ; 

 cymules each 2- or oftener 3-flowered, 4-bracteate ; 2 bracts dilated 

 at base, at apex cuspidate subspinescent ; 2, alternating with the 

 above, widely membranous (coloured ?) cucuUately concave veined.^ 

 {French Guiana,^) 



38. Declieuxia H. B. K.^ — Flowers 4-merous; receptacle ex- 

 ternally orbicular- compressed or obcordate. Folioles of calyx 2 

 (Congdonia *), or 4, free or more or less connate, equal, or 2 lateral 

 much larger, persistent. Lobes of funnel-shaped corolla 4, valvate ; 

 throat variously covered. Stamens 4 ; filaments slender, inserted in 

 throat; anthers oblong, often exserted, versatile, introrsely 2-rimose. 

 Germen inferior, 2-celled, much compressed contrary to septum; 

 epigynous disk rather thick, very small or ; branches of slender style 

 2, thin, exserted, papillose throughout. Ovules in cells solitary 

 ascending ; micropyle extrorsely inferior.^ Fruit subdidymous, finally 

 dry or with a slightly fleshy exocarp ; raphe of suberect compressed 

 seed ventral or lateral; albumen fleshy; radicle of small embryo 

 inferior. — Branched shrublets or herbs, glabrous or scaberulous ; leaves 

 opposite or more rarely verticillate, petiolate or sessile, coriaceous, 

 venose, sometimes cordate; stipules short setiferous or 0; flowers^ 

 in scorpioid-cymose branches of terminal inflorescence 1 -lateral, 

 2-bracteolate or ebracteolate.^ (Cent, and trop. America.^) 



39. Lasianthus Jack.^ — Flowers hermaphrodite or 1 -sexual 

 (nearly of Uragoga), 4-6-merous; lobes of funnel-shaped, hypocra- 

 teriform or subcampanulate corolla valvate. Stamens 4-6, inserted 

 in throat of corolla or between lobes ; anthers enclosed or subexserted, 

 more rarely in male flower much exserted ("^ Allceophania ^°). Germen 

 2-celled (Saldinia ^^) or 4-10-celled (AUceophania, Eulasianfhus); disk
