490 NATURAL HISTORY OF PLANTS. 



dal ; valves finally contorted; placentas marginal. Seeds oo, ascending, 

 imbricate, produced below to an acute caudex and above to a long oo- 

 setose pencil; albumen fleshy; cotyledons of straight embryo elliptical; 

 radicle short inferior. — Radicant glabrous shrubs ('^sometimes epi- 

 phytal"); leaves opposite rather fleshy, petiolate; stipules membranous 

 interpetiolar, caducous ; flowers ^ terminal solitary, sometimes sessile, 

 bracteate and bracteolate.^ (Trop. America, Antilles.^) 



182. Calycophyllum DC* — Flowers 5-merous or more rarely 6- 

 8-merous ; receptacle oblong-cylindrical. Calyx gamophyllous entire, 

 sometimes first nearly closed and then fissous (Schizocalyx^), oftener 

 dentate or lobed ; lobes sometimes induplicate {Pallasia ®) ; one pro- 

 duced to a (coloured) foliaceous petiolate lamina, or all more rarely 

 short (Ejihylista^). Corolla funnel-shaped or hypocrateriform ; tube 

 straight or slightly curved ; throat variously pilose ; lobes of limb 5, 

 or more rarely 6-8, imbricate. Stamens as many, inserted in throat 

 or tube (Pallasia, Scliizocahjx) ; anthers oblong introrse, generally 

 exserted, versatile, sometimes unequal (Pallasia), Germen 2-celled; 

 disk annular ; lobes of often 2-form style 2, various in form, some- 

 times in bud exserted from corolla. Ovules oo, inserted on placentas 

 adnate to linear septum. Fruit capsular cylindrical, truncate at apex, 

 septicidal. Seeds oo, horizontal or oblique, often imbricate, either 

 angular or compressed, scarcely or not at all winged^ (Warscewiczia, 

 Pallasia), or produced both ways to a more or less elongate wing 

 (Enkylista, Calycophyllum) ; albumen fleshy ; cotyledons of small 

 embryo subovate ; radicle terete. — Trees or shrubs ; leaves opposite, 

 ovate or oblong, petiolate ; stipules interpetiolar, entire, ciliate or 

 pubescent, deciduous or calyptrately secedent (Schizocalyx) ; flowers * 

 in terminal compound-racemose cymes, corymbiform or sometimes 

 (Pallasia, Warscewiczia) 1- parous and inserted on a long spikelike or 

 racemiform axis ; bracts sometimes foliaceous. ^° {Trop. S, America 

 and Antilles,^ ^)
