Flowers creamy-white. In open thickets on the Shweli-Salween divide. Lat. 25°30' N. Alt. 10,000 ft. July 1917." This species has flowers as large as those of Turpinia pomifera (Roxb.) DC. The leaflets, although acuminate, have not the elongate apex which marks most of the collections of the latter species. The fruits are scarcely at all fleshy and not nearly so large as in T. pomifera (Roxb.) DC. Indeed, it would seem that this species is the explanation of why T. pomifera (Roxb.) DC. and T.

Merr. in the flowering state by the open lax inflorescence with flowers almost twice as large, is somewhat difficult to distinguish in the more nearly mature fruits. In all the specimens cited we have been able to see, around the subpersistent bases of the styles, some remnants of the pubescence which is readily seen on the pistil in the flower. The leaves usually have 5-9, sometimes 11, leaflets, a little broader than in the related species and more closely serrate.
