papillose. Fruit samaroid ; carpels 2, solute from axis (sometimes 

 with difficulty) dehiscent compressed and dorsally produced superior 

 to ajiex of style or shorter ; seeds scantily albuminous ; testa thin ; 

 cotyledons membraneous, often lateral. [East India, trop. W. 

 Africa}') 



134. Baccaurea Lotjr.^ — Flowers monoecious or dioecious (nearly 

 of Richcria or Seciirinega apetalous ; sepals 4, 5, imbricated, sometimes 

 unequal. Disk or rudimentary, sometimes more rarely evolute 

 {Adcnocrejns^ Isandrion'^'). Stamens inserted below rudiment of 

 gynseceum either equal in number to sepals and opposite them 

 {Hcdycarfus^ Cal/jptroon ^), or sometimes 4-10, 2-seriate, or 1-seriate, 

 some in pairs before each sepal ; filaments free ; anthers introrse or 

 more rarely extrorse {Calyptroon) ; cells longitudinally adnate and 

 rimose. Germen (in male flower rudimentary lobed) siUTounded by 

 hypogynous disk more or less evolute or ; cells 2 (Isandrion, Jdeno- 

 crepis, Calyptroon), or 2, 3 {Pierardia ^), sometimes 4, 5 [Hedycarpus) ; 

 ovules in each cell 2 ; obtm-ator usually thick ; style generally short 

 or very short (Jdcnocrepis) branches 2-5, rather wide, 2-3-lobed or 

 unequally lacerate, inwardly at apex papillose. Fruit 1-5-loeular 

 indehiscent ; pericarp pachydermous more or less fleshy ; seeds 

 albuminous more or less fleshy arillate.^ — Trees or shrubs ; leaves 

 alternate petiolate 2 -stipulate entire or denticulate penninerved ; ribs 

 and primary nerves prominent below ; indumentum simple, 

 stellate or ; flowers in axillary simple or ramified racemes ; bracts 

 often more or less connate, with peduncle usually cymose few- 

 flowered." (Trop. regions of Asia, Oceania and W. Africa}''^) 



135. Uapaca H. Bn." — Flowers dioecious apetalous ; calyx 

 gamophyllous, 4-5-dentate or sepals 4, 5, imbricated. Stamens 

 4, 5 ; filaments free mserted below entire rudiment of gynse- 

 ceum dilated at apex ; anthers introrse, 2-rimose, Disk in
