A shrub, clothed with hooked prickles. Leaves very variable in size, 4-12 in. j 

 petiole arched, usually very prickly along the back ; leaflets in young specimens ovate- 

 lanceolate, very long-acuminate, crenate-serrate, pale, nerves very distinct beneath, in 

 older ones more elliptic or oblong, 2-2^ in. long in Kumaon specimens, upwards of 4 in. 

 in some Sikkim ones, coriaceous, shining above. Cymes much branched many- 

 flowered. Flowers the largest of the Indian species, ^-J in. diam., umbellate, on the 

 branches of the cyme ; pedicels slender, longer than the petals. Sepals 4, small, 

 obtuse. Petals 4, obtuse, imbricate Sipe carpels 2-4, the size of a pea, tubercled, 

 hardly beaked. Seed black. 



6. Z. Ubasianum, .^00^./. ; branches petioles and inflorescence pubes-

 Cymes (9 only seen) 2 in., panicled, spreading, very pubescent. Ripe carpels 1-3, about 

 i in. diam., globose, not beaked. Seeds globose, black. — I have not ventured to unite 

 this with the \ery similar Chiuese Z. cuspidatum. Champ, {in Kew Journ. Sot. iii. 329), 

 though this agrees entirely in habit, the curious form of the alternate petioled small 

 leaflets, and in the paniculate cyme and frait ; it differs in being very pubescent on the 

 branches petiole and rachis of the leaf and cyme, and in the small less coriaceous and 

 less shining leaves, that do not blacken in drying. 



7. Z. Kamiltonianum, Wall Cat. 7117 ; prickles few short, branches 

 and petioles glabroas or more or less pubescent or velvety, leaflets 

 4-7 in., 2-3 pairs, opposite glossy oblong not sinuate, cymes axillary tomen-
