This is a perfectly good and distinct species. Mr. Lawson however, 

 misled no doubt by Wallich's wrong identification of No. 4242 of his 

 catalogue as Z. glabra, E;Oxb., and in the absence of an authentic speci- 

 men of the species, reduced this (in Hooker's Flora of Brit. India I, 636,) 

 to a glabrous form of Z. rngosa Lamk., which is a plant with a totally 

 different inflorescence. The nearest ally of this is undoubtedly the 

 Indian Peninsular species Z. trinervia Roxb., which was published by 

 Eoxburgh in his Hortus Bengalensis in 1813 as Z. tririervius, and of 

 which a full and excellent description was given as Z. trinervia in his 

 Flora Indica I, 606. The synonymy of this species is rather curious, 

 and I therefore make a note of it here. Roth described what is 

 undoubtedly a different plant in his Nova3 Flantarum Species (pub- 

 lished in ]821) as a species of his own under the name Z. trinervius, 

 and of that plant he describes, as var. glabratus, a form to which he 

 reduces Z. glahratus Heyne, which is unmistakably the Z. trinervius of 

 Roxburgh ; I can find no other publication of Heyne's Z. glahratus than 

 this one of Roth's. Unfortunately Mr. Lawson has taken Heyne's 

 name as that of the species, although Roxburgh's dates from 1813.

 Young branches sparsely puberulous ; spines short, curved, usually 

 solitary or with a second abortive. Leaves ovate-elliptic or ovate-lanceo- 

 late, acuminate, minutely serrate, the base slightly narrowed, some- 

 times oblique or sub-cordate, glabrous on both surfaces, the latter with 

 a few scattered haii-s on the nerves ; vertical nerves 3, bold, impressed 

 on the upper and pronaiueut on the lower surface, the middle one un- 

 branched, the two lateral sending bold curved ascending branches 

 towards the margin ; length 2'5 to 3 in., breadth 1 to 1"75 in., petiole 

 *3 to '5 in. Cymes longer than the petioles, branched, few-flowered. 

 Flowers on pedicels longer than themselves ; calyx puberulous outside, 

 glabrous inside : disc tomentose with a glabrous 10-crenate wavy 

 edge, not pitted; styles united to the apex. Fruit globular, slightly 

 compressed, 5 to "6 in. in diam., densely but minutely tawny-tomentose.

This species much resembles Z. glabra, Roxb , but the outer nerves 

 of the leaves are boldly branched outwards, and the fruit is minutely 

 tomentose. The specmiens of this are scanty. When more materials
