the shortly ovate anthers ; apical connectival appendage deflexed, 

 curved, longer than the anther. Ovary elongated-conic, tomentose, 

 tapering into the sparsely puberulous style; stigma small. Ripejruit 

 narrowly ovoid, apiculate, pale biownish-tomentose, 3 25 to 1"5 in. long. 

 and "75 to 1 in. in diam. Persistent sepals nearly equal, their bases 

 thickened, Tvoody, pubescent, and concave, forming an irregulaily5-toothed 

 cup which embraces the lower half of the fruit. Shorea Hevisleyana,

This is an altogether anomalous species. It has leaves like 

 several of the scabrid species of Shorea, such as S. eximia and S. 

 leprosula. Its flowers are also more like tliose of Shorea than Balano- 

 carpns ; but its fruit is essentially that of the latter genus, in which, 

 not without hesitation, I include it. 



10. Pachynocarpus, Hook. fil. 



J- trees with the leaves and flowers of Vatica, but with 



sonnet. i: y ten stamens. Fruit ovoid-globose, umbonate at the apex, 



1-ceiled, ■- eded, the pericarp densely coriaceous, splitting vertically. 

 Calyx with five equal segments, at first almost free from the fruit, but 

 the tube gradually accrescent, much thickened and adnate to the fiuit, 

 and finally embracing the whole of it except the apex. Seed pendulous, 

 testa thin and adherent to the endocarp, cotyledons very thick and fleshy. 



Leaves elliptic to oblong-elliptic, sub-acute or 



shortly and obtusely acuminate... ... 1. P. Wallichii. 



Leaves broadly-elliptic or obovate-elliptic, the 



apex very blunt ... ... ... 2. P. Stapfianus. 



Dr. Burck (in Ann. Jard. Bot. Buitenzorg) expands the definition of the genu8 

 Vatica so as to include not only the closely allied Synaptea, but also the genera 

 Isauxis W. A , Retinodcndron, Korth., and Pachynocarpus Hook fil. To the union 

 of Synaptea with Vatica I see no objection ; for the whole difference between the two 

 (as I have stated in a note under Vatica) consists in perfect freedom of the fruit 

 in Vatica from the enlarged calyx, whereas in Synaptea there is a slight adhesion to 

 the calyx at the very base. But for the inclusion of Pachynocarpus, I see no suflHcient 

 justification ; for in this genus the calyx does not expand into membranous wings, but 

 forms a dense fibro-cartilaginous cover for the fruit, which it tightly embraces, and 

 to which it is quite adnate. As regards Isauxis and Retinodcndron, they appear 

 to -' to be undistinguishable from each other by any but trivial marks, but they 

 differ sufficiently in calyx from Vatica to be treated as a genus under the older 

 name Retinodendron. 



1. Pachynocarpus Wallichii, King. A tree 40 to 70 feet high : 

 young branches deciduously scurfy-pubernlous, their bark pale-brown 

 sparsely lenticellate. Leaves coriaceous, elliptic to oblong-elliptic,
