105 ? Didymopanax Done, 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 Sclufflera (of 

 Heptapleurwn) ; 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 earhke 

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

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

 pedicels not articulate. (iV^. Caledonia.^) 



107. Gastonia Commeks.* — 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,
