lY. MAPPIE^. 



42. Mappia Jacq. — Flowers hermaphrodite or polygamous, 5- 

 merous, calyx small dentate or cut. Petals same in numher alternate 

 longer inwardly or on all sides villose or barbate, valvate ; apex 

 incurved. Stamens equal in number to petals alternating with 

 them ; filaments inserted below hypogynous disk, more or less 

 evolute, fi.liform at base or dilated and cohering there sometimes 

 with margin of petals ; anthers ovate or oblong introrse ; cells con- 

 tiguous or remote longitudinally rimose ; connective equal to cells 

 or produced beyond them above. Germen free, 1-locular (very 

 rarely 2-3-locular) ; style eccentric more or less elongate and be- 

 fore anthesis plicate, inflexed or incurved, capitate stigmatiferous at 

 apex ; base sometimes accompanied with two short horns (abortive 

 style branches (?). Ovules in cell 2-nate, collaterally descend- 

 ent; micropyle introrse superior, sometimes obturated with small 

 dilatation of funicle. Drupe glabrous or villous ; flesh often scanty ; 

 putamen ligneous or crustaceous, sometimes pergamentaceous ; 

 raphe of descendent seed dorsal, sometimes prominent ; albumen 

 fleshy ; cotyledons of rather large axile embryo, flat or sigmoidal 

 foliaceous thinly membranous ; radicle short superior. — Trees or 

 shrubs, sometimes scandent volubile ; branches often (from elevate 

 adnate twigs) angulate or oostate ; leaves alternate, exstipulate, 

 simple, penninerved reticulate-veined ; flowers in variously com- 

 pound ramified terminal lateral or oppositifolious cymes being ad- 

 nate to branches from the base for a longer or shorter distance. 

 {Trop. America^ South trop. Jsia., irop. West Africa). See p. 277. 



43. Poraqueiba Aubl.^ — Flowers (nearly of Mappia) hermaphro- 

 dite or polygamous ; calyx lobes, 4, 5, subimbricate. — Petals furnished 

 inside with promiiieht plates or ribs ? ^ Stamens 5, alternipetalous ; 

 filaments dilated ; anthers erect introrse. Germen and ovule of Mappia; 

 style short, stigmatose subdiscoidal at apex. Fruit nearly that of Map- 

 pia ; cotyledons of incurved or nearly straight shorter by half than the 

 albumen embryo wide slenderly foliaceous; radicle short dilated su- 

 perior. — Glabrous or silky trees; leaves alternate simple coriaceous; 

 flowers in short contracto-capitate cymuliferous racemes capitules
