 of India, in the Nilgherries, as well as the Himalaya. 



Order XXXIV. TEREBINTHACE^. 



Flowers partially or wholly unisexual, or more rarely hermaphrodite. Se- 

 pals 5, or rarely 3, 4, or 7, more or less united and usually very small. Petals 

 as many, inserted on the outside or margin of a pengynous or hypogynous

 Albumen none. Eadicle usually next the hikiin. Cotyledons thick and fleshy. 

 — Trees or shrubs, sometimes climbers, usually with a resinous, gummy, caus- 

 tic, or milky juice. Leaves alternate, usually pinnate, sometimes simple, not 

 dotted, without stipules. Flowers small, paniculate. 



A large Order^ widely distributed over the warmer and temperate regions of the globe. 

 Stamens alternate with the petals. Ovules solitary {Anacardiece) . 1. Rhus. 

 Stamens opposite the petals. Ovules 2 in each cell {3Ieliosmece) . . 2. Sabia. 



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, cui-ved 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. ^. succedaneum. 



Leaves white-cottony underneath. Panicles and drupes downy . . 2. i2. 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 oft'. 

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

 glmidifoUns, Hook, and Am. Bot. Beech. 179. 



In the Happy Valley, Cham'pion 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 U. acuminata, DC, which seems to be a mere variety, with 

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

 specimens. 



2. R, h3rpoleuca, Champ, in Kew Jonrn. Bot. iv. 43. A tree. Leaves 

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

 ovate-lanceolate, somewhat acute, 2 to 2i in. long, oblique at the base, with
