surface glabrous, or the midrib and lateral nerves slightly stel- 

 late-tomentose ; lateral nerves 4 to 6 on each side of the midrib, 

 very prominent on the lower surface, somewhat ascending, anas- 

 tomosing, the reticulations distinct; petioles 2.5 to 6 cm long, 

 stellate-tomentose. Panicles terminal, corymbose, peduncled, up 

 to 11 cm in diameter, the lower branches 4 to 6 cm in length. 

 Flowers white, numerous but not crowded, the subtending brac- 

 teoles linear, 1 to 2 mm long, the bracts similar but much larger, 

 the pedicels 1 to 2 mm long, jointed to the calyx. Calyx cup- 

 shaped, about 3 mm long, externally rather densely stellate- 

 tomentose with cinereous hairs, obscurely 2-lipped, subequally 

 5-toothed, the teeth 0.5 to 0.8 mm long, acute. Corolla 5 mm 

 long, the upper part externally stellate-tomentose, eglandular, 

 2-lipped, the upper lip entire, rounded, cucullate, suborbicular, 

 2 to 2.5 mm in diameter, the lower 3-lobed, the central lobe 

 elliptic-ovate, rounded, about 1.8 mm long, the two lateral ones 

 slightly shorter. Ovary tomentose. Filaments glabrous. Fruit 

 ellipsoid-obovoid, about 4 mm long, when young stellate-tomen- 

 tose, ultimately glabrous.

A species manifestly allied to Premna cumingiana Schauer, from which 

 it is readily distinguished by its simply stellate, comparatively sparse 

 indumentum. In Premna cumingiana the indumentum on many parts is 

 distinctly plumose, while on some parts the plumose hairs are intermixed 

 with much longer simple ones; the lower surface of the leaves is very 

 densely and uniformly covered with indumentum, while in the present 

 species the indumentum is practically confined to the midrib and lateral 

 nerves. Premna stellata Merr. is also closely allied to the Javanese form 

 that has been referred to Premna tomentosa Willd., the oldest name for 

 which appears to be Cornutia corymbosa Burm., based on Ceylon specimens. 

 It is not the same as the Javan plant, however, differing in its abruptly 

 acuminate, fewer-nerved leaves. It is also sufficiently distinct from the 

 Asiatic Premna pyramidata Wall.
