filaments, 5-adelphous, 1 -antheriferous ; anthers reniform, 1-locular. 

 Germen 3-5-locular, ovules in each cell 2, inserted at internal angle, 

 ascending ; micropyle extrorse lateral; style capitate stigmatiferous at 

 apex. Fruit large, vertically 5-winged, dry, linear-ligneous at centre, 

 indehiscent. Seed sometimes 1, involute in gummy pulp, suberect; 

 embryo exalbuminous, cotyledons contortuplicate, involving short 

 inferior radicle. — Lofty trees ; coma often aphyllous at anthesis ; 

 hairs stellate ; leaves alternate petiolate digitate- 5-7-lobed; flowers' 

 ebracteolate, in umbelliferous cymes (Trop. America"). 



82. Hampea Schltl. 3 — Flowers hermaphrodite, or oftener polyga- 

 mous ; calyx cyathiform, straight truncate or obscurely 5-crenate, or 

 dentate, valvate, or slightly imbricate. Petals 5, oblique, obovate, 

 longer than calyx, connate at base among themselves, and with staminal 

 tube, inwardly villous at base ; prsefloration contorted. Stamens co, 

 1-adelphous ; tube short, filaments afterwards free elongated ; anthers 

 reniform. Germen (in male flower rudimentary or 0), 3-locular; 

 style short, apex divided into short thick stigmatiferous lobes. 

 Ovules in cells few. Capsule globose, encircled by base of calyx, locu- 

 licidal, inwardly more or less densely villous. Seeds few, unequally- 

 ovoid or subglobose ; funicle dilated in thick fleshy conoid 

 aril ; albumen scanty membranifqrm ; embryo fleshy oleose- 

 punctuate ; cotyledons much contortuplicate, involving straight 

 inferior radicle. — Small trees ; leaves alternate, generally long petio- 

 late, stipulate, entire, cordate or subcordate palminerved at base ; 

 stipules narrow linear, often acuminate, deciduous ; flowers axillary 

 cymose ; bracts 3 inserted at summit of pedicel 4 {Columbia, Mexico'). 



83. Scleronema Benth. 6 — Calyx clavate campanulate ; 4-5-lobed, 

 valvate. Petals 4, 5, contorted, base scarcely adnate to staminal 

 column. Stamens 8, base of filaments connate in short tubular
