There being no flowers with the specimens enumerated, they have been 

 described from Korthals, I.e. The Sumatra specimens have leaves which are more 

 or less hairy or bristly on the upper side and represent Blume's var. pilosiuscula of 

 S. begoniaefolia (Blume, Mus. I. 11) or S. moluccana var. pilosiuscula Stapf, I.e. 

 A specimen from South Borneo, collected by Motley, is almost glabrous on the 

 upperside of the leaves. 



35. Sonerila glabriflora, Stapf and King. A creeping or ascend- 

 ing herb, a few inches high, with a long creeping rhizome, hairy on the 

 stem, peduncles, petioles and the nerves on the underside of the leaves, 

 otherwise glabrous ; hairs reddish, straight, adpressed. Stem rather 

 stout, slightly swollen at the nodes, frequently rooting, leafy part 

 1-4 in. long. Leaves very dissimilar, the larger of each pair petioled, 

 asymmetric, obliquely elliptic, obtuse or subacute, unequally cordate 

 at the base with a large, rounded lobe on the outer and small or 

 obscure one on the inner side, entire or obscurely and remotely toothed, 

 fleshy, soft, dark glossy-green above, pale with purple nerves beneath, 

 3-6 in. by 2-3'5 in., with 3-5 lateral nerves in the outer and 2-3 in the 

 inner half near the base and with rather lax subhorizontal transverse 

 veins ; petiole rather stout, l-2'5 in. long, the small leaves sessile, 

 reniform-cordate, *2-2h in. in diam. Cymes terminal and axillary, usually 

 2- or 3-nate on a common peduncle, ebracteate, many-flowered, rather 

 dense, glabrous, when ripe up to 1'3 in. long, common peduncle 1-2 

 in., special peduncles '5-1*2 in. long, slender; pedicels very slender, 

 •1-12 in. long. Calyx campanulate-ovoid, , 12- , 15 in. by '06 in. ; teeth 

 very broad and short. Petals elliptic, acute, almost *25 in. long, white
