A shrub? Leaflets 3-i in., coriaceous, subsesaile, petioles not armed. Cymes in 

 slender panicles, quite glabrous. Flowers ^-^ ia. diam., 4-5-merous. PcteZs valvate. 

 Eipe carpels solitary, the size of a pea, smooth. — Wight makes 2 species of this, whicli 

 I cannot distinguish except as vaiieties. The Khasian and Assam specimens have 

 rather longer leaves than the Madras ones.

Hot valleys of the Subtropical Himalaya, ascending to 6000 ft. from Jamu to 

 Bhotan ; Khasia Mts., alt. 2-3000 ft. 



A shrub or small tree, with dense foliage and pungent aromatic taste and smell ; 

 prickles often vertically flattened on the trunk and branches, the older .with a corky 

 base. Leaves 1^-9 in. (in Khasia specimen) ; petiole glabrous, narrowly winged, with 

 2 stipnlar prickles at the base ; leaflets |-4 in., naiTow, usually elliptic-lanceolate, rarely 

 ovate, obtusely acuminate. Panicles loose, sparingly branched. Flowers ^-J.^ in. 

 diam. Calyx 6-8-lobed, lobes subacute. Stamens d-S. Bipe corpcfe ^—i. in. diam., 

 usually solitary, laxly panioled, broadly ovoid, pale red, tubercled. — Youngleaflets have 

 often the costa prickly beneath, and usually few large scattered glands. The wood is 

 hard and used for tooth cleaning, and the carpels as a condiment. 



3. Z. acantbopodium, DC. Prodr. ii. 727; branchlets glabrous or 

 tomentose, leaflets 2-6-pairs lanceolate, nerves distinct glabrous or more or 

 less pubescent beneath, petiole and racnis narrowly winged, cymes very short 

 dense .^-1 in. long pubescent. Z. hostile, WaU, Gat. 1210, and Z. alatum, 

 Wall. Cat. \209,' in pari. 



Hot valleys of the Subtropical Himalaya, from Kumaon to Sikkim, ascending to 

 7000 ft. ; Khasia Mts., alt. 4^6000 ft. 



Very similar indeed to Z. alatum, and possibly a variety of that plant, but the leaflets 

 have never the large scattered glands, and are often very pubescent beneath, the nerves 

 are much stronger, and the inflorescence is remarkably diflei-ent, the ripe carpels (J in. 

 diam.) forming dense sessile and almost globose clusters on the branches below the 

 leaves. — The Z.planispinum, Sieb. and Zucc, of Japan, is probably another variety, 

 with fewer glabrous leaflets, faint nerves, and glabrous inflorescence ; it is intermediate 

 between this and Z. alatum, to which it is most nearly allied, but wants the largo 

 glands. Wallich in his catalogue quotes Z. ncanthopodium, DC, as a synonym of 

 Z. alatum, Roxb., and the ticket is attached to a specimen with very short cymes and 

 crowded points, and with leaves pubescent beneatb. I therefore retain De Candolle'.s 

 name for this plant, which is quite distinct from Roxburgh's Z. alatum.
