 herb, a few inches high, densely hirsute or tomenfcose on the stem, the 

 petioles and more or less also in the inflorescence, including the calyx ; 

 adpressedly strigillose on the nerves and veins on the underside of 

 the leaves, and with scattered, often very few, stouter hairs on the

 inflorescence flexuous, more or less spreading. Stem prostrate below, 

 subflexuous, leafy part rarely more than 1 in. long. Leaves crowded,

 sometimes almost symmetrical, obliquely (if asymmetrical) obovate- 

 oblong or oblong, subacuminate, unequally cordate at the base with 

 a rounded lobe ('2 in. long) on the larger and a minute lobe on the 

 narrower half, entire, ciliolate along the margin, membranous, dark 

 green, 3-6 in. by l'3-2'5 in., 6- or rarely 7-nerved from near tlie base 

 with 3 (rarely 4) nerves in the broad and 2 in the narrow half, with 

 oblique, conspicuously prominent, transverse veins on both sides ; petiole 

 stout, •3-5 in. long; small leaves ovate-cordate to reniform, minute

Perak (?) ; foot of Gunong Panti, Kunstler 220 ! 



Rather closely allied to S. Beccariana, Cogn. ; bat this has on the whole 

 narrower, more acuminate leaves and much larger fruits.

 herb, 3-5 in. high, softly hirsute or shaggy all over ; hairs dense and more 

 or less spreading on the stem, the petioles and all parts of the inflorescence 

 (inclusive of the calyx), looser on both sides of the leaves, pale reddish, 

 rather long and flexuous. Stem prostrate below. Leaves very dissimi- 

 lar, the larger of a pair petioled, asymmetrical, obliquely elliptic, 

 acuminate, unequally cordate at the base with a large, rounded lobe 

 ('4 in. long) on the outer and a much smaller lober on the inner side, 

 entire or subentire, membranous, on both sides light-brown when dry, 

 4-6 in. by 2 2-3 in., about 7-nerved from near the base, with 4 nerves

 oblique, transverse veins, uppermost side-nerve 1-1 "25 in. above the base ; 

 petiole stout, •5-l'2 in. long ; small leaves ovate-cordate to reniform, 

 up to '25 in. long, on short, slender petioles. Gymes terminal and in the 

 uppe^: axils, solitary or 2 or a common short peduncle, ebracteate,
