1. RHUS, Linn. 



Sepals, petals, and stamens 5. Ovary 1-celled, with 3 short styles or stig- 

 mas. Ovule 1, suspended from an erect filiform funiculus. Drupe small, 

 oblique, with very little juice or nearly dry. Radicle short, curved against 

 the edge of the flat cotyledons. — Trees or shrubs. Leaves pinnate in the 

 Chinese species. 



A considerable genus, with nearly the geographical range of the Order, but less abundant 

 within the tropics than in subtropical and temperate regions. 



Leaves, panicles, and drupes quite glabrous 1. R. succedaneum. 



Leaves white-cottony underneath. Panicles and drupes downy . . 2. R. hypoleuca. 



1. R. succedaneum, Linn.; DC. Prod. ii. 68; Wight, Ic. t. 560. 

 A tree or tall shrub, quite glabrous in all its parts. Leaves pinnate, the 

 common petiole slender, not winged, 6 to 8 in. long. Leaflets 11 to 15, ob- 

 long or ovate-lanceolate, acuminate, 2 to 3 in. long, the point long and acute, 

 very oblique at the base, green on both sides and shining above. Panicles 2 

 to 4 in. long, clustered in the axils of the leaves, the males more branched 

 than the females, the branches spreading. Petals small and soon falling off. 

 Drupes about 4 lines broad, very oblique, and quite glabrous. — Connarus ju- 

 glandifolius, Hook, and Arn. Bot. Beech. 179. 



In the Happy Valley, Champion and others. In S. China, north-east India, and north- 

 ward to Japan. In one specimen gathered by Wright the leaflets are narrow as in our 

 Japanese ones ; in the others they are broader, with long points and more transverse veins, 

 "approaching the north Indian R. acuminata, DO, which seems to be a mere variety, with 

 usually, but not always, fewer leaflets. The venation is somewhat variable, even on the Baine 

 specimens. 



2. R. hypoleuca, Champ, in Kew Journ. Bot. iv. 43. A tree. Leaves 

 pinnate, the common petiole cylindrical, 8 to 10 in. long. Leaflets 11 to 17,
