194 NATURAL HISTORY OF PLANTS. 



descending seed very scanty or ; cotyledons of curved embryo 

 fleshy plano-convex, or sometimes [Pachytrophe) thinner subrotund 

 and more or less plicate ; radicle accumbent or more or less incum- 

 bent ascending. — Trees or shrubs ; juice opaline ; leaves alternate 

 petiolate entire coriaceous, oftener rough beneath ; stipules more or 

 less coalescent in one semiamplexicaul, deciduous ; inflorescence 

 axillary pedunculate ; receptacle very elongate spikelike marginally 

 glomeruliferous on both sides, each surface longitudinally sulciform 

 and destitute of flowers ; bracts crowded oftener peltate.^ (Mada- 

 gascm^ Mascarem islands.^) 



14 ? Paratrophis Bl.^— Flowers (nearly of Morus or Ampalis) 

 dioecious ; male sepals valvate or slightly induplicate or imbricate. 

 Female sepals 4, herbaceous, scarcely or not at all growing around 

 fruit, not fleshy. Germen and other characters of Morus (or 

 Ampelis), Fruit drupaceous slightly fleshy ; albumen of descending 

 seed thin, generally thicker between the folds of the embryo. 

 Embryo incurved; radicle ascending incumbent; cotyledons equal 

 plicate and conduplicate, parallel or sometimes (Uromorus^) not 

 parallel and unequally lobed. — Milky trees; alternate leaves and 

 inflorescence of Ampalis ; receptacles amentiform solitary or 2-nate, 

 subcylindrical or sometimes ( Uromorus) very long,^ densely glome- 

 rulate. [New Zealand^ Pacific Islands,^) 



15 ? Pseudomorus Bur.^ — Flowers (nearly of Paratrophis or 

 Ampalis) ; sepals 4, imbricate, not accrescent, persistent around base 

 of fruit. Gynsecium and other characters of Morus (or Ampalis), 

 Fruit drupaceous ; pericarp thin slightly fleshy ; embryo of descend- 

 ing subglobose seed thick compressed subglobose ; radicle ascend- 

 ing accumbent; cotyledons fleshy hemispherical; albumen scanty 

 and well conspicuous only around radicle. — A lactifluous tree;
