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

 misled no doubt by Wallioli's wiong identification of No. 424<2 of his 

 catalogue as Z. glabra, Roxb., and in the absence of an authentic speci- 

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

 to a glabrous form of Z. rugosa Lamlc, which is a plant with a totally 

 different inflorescence. The nenrest ally of this is undoubtedly the 

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

 Roxburgh in his Hortus Bengalensis in ]8J3 as Z. trinervius, and of 

 which ix, full and excellent description was given as 2^. ^rwert'ia in his 

 Flora Indica I, 606. Tiie 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 Novx Plantarum Species (pub- 

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

 and of that plant he describes, as var. glabratns, a form to Avhich he 

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

 Roxburofh ; I can find no other publication of Heyne's Z. glabratus than 

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

 name as that of the species, although Roxburgh's dates fiom J813.

 Young branches sparsely pubeiulous ; spines short, curved, usually 

 solitaiy 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, tlie latter with 

 a few scattered hairs on the nerves ; vertical nerves 3, bold, impressed 

 on the upper and prominent on the lower surface, the middle one uu- 

 bianched, the two lateral sending bold curved ascending branches 

 towards the margin ; length 25 to 3 in., breadth 1 to 1"75 in., petiole 

 '3 to -6 in. Cymes longer than the petioles, branched, few-flowered 

 Flmvers on pedicels longer than themselves ; calyx puberulous out.'^ide, 

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

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

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

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

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