105? Didymopanax Dcne. and Pl.^ — Flowers hermaphrodite ; ^ 

 calyx small dentate. Petals valvate. Disk epigynous flat or concave, 

 undulate at margin. Germen 2-celled ; styles 2, free, sulcate within. 

 Ovules descending; funicle short, sometimes thickened to obturator. 

 Fruit drupaceous, much compressed contrary to septum, broadly sub- 

 2-dymous ; sarcocarp thin ; pyrenes much compressed, crustaceous 

 or cartilaginous ; albumen of flat seed uniform. — Trees or shrubs, 

 sericeous or velvety, more rarely glabrous ; leaves simple or oftener 

 digitate ; folioles petiolulate ; stipules small adnate to petiole ; 

 umbellules (sometimes racemiform) in compound racemes ; pedicels 

 inarticulate. {Trop. America^) 



106 ? Eremopanax H. Bn.* — Flowers nearly of Schefflera (of 

 Heptajjleurum) ; calyx short. Petals 5, valvate. Stamens 5, inserted 

 under conical epigynous disk (at apex scarcely depressed stigmatose); 

 filaments much incurved. Germen inferior, 1-celled, 1-ovulate. 

 Fruit drupaceous ; putamen 1, unsymmetrical, more or less gibbous 

 on both sides to apex, sometimes produced to a thick woody earlike 

 wing, 1-spermous. Seed descending; albumen uniform. — Climbing 

 (?) shrubs; leaves digitate or partly simple; umbels compound; 

 pedicels not articulate. (N. Caledonia.^) 



107. Gastonia Commees.^ — Flowers'' (nearly of Schefflera) her- 

 maphrodite or polygamous ; calyx short, undulate or crenate. Petals 

 8-15, thick, valvate. Stamens equal in number to petals or nearly 

 so ; filaments much inflexed, inserted under flat or depressed conical 

 epigynous disk. Germen 8-15-celled ; style very short thick ; lobes 

 small obtuse, in verticil, sometimes scarcely prominent {Trevesia^), 

 Fruit drupaceous ; pyrenes 8-15 ; seed uniform. — Trees or shrubs, 

 glabrous, stellately pubescent or aculeate ; leaves palmatifid or 

 digitate (Trevesia), or pinnately compound ^ (Reynolds ia, ^^ Eugastonia) ;
