 in diam., axillai'y, usually in pair.s, or in cymes, I to 2 in. long, the 

 cymes minutely pubescent ; bracts few, lanceolate ; pedicels long, with 

 several broadly lanceolate, partly deciduous bracteoles, or ebracteolate. 

 Sepals free, or connate below, reniform, or broadly ovate, puberulous out-

 lous on both surfaces. "15 in long. Inner petals 3 in. long, thick, vaulted 

 reniform-sagittate, puberulous, with a glabrous callosity on the inside 

 near the base, the edges pubescent ; the claw shoi'ter than the limb, 

 pubescent. Male Jloicer : stamens very numerous, short, cuneate ; the 

 connective truncate, small and not concealing the tops of the anthers ; 

 pistils 3, or a few rudimentary. Female flower ; slaminodes in two im- 

 perfect rows. Ovaries about 12, ovoid-cyliudric, oblique, pubescent,

This species, although rare in Penang, is very common in Perak. 

 Specimens of it vary considerably in several respects. In some plants 

 the young shoots are densely puberulous, in others they are almost 

 glabrous ; the leaves also vary in size and in amount of pubescence. In 

 the specimen figui'ed by Professor Oliver (Hook. Ic. PI. 1562), the 

 flowers are in axillary pairs ; but, in the majority of the Perak specimens, 

 they are in cymes. The species is practically dicEcious, the staminate 

 flowers having no ovaries at all or only a few rudiments ; while the 

 pistillate flowers have rarely a few perfect stamens, and not always 

 any staminodes. The best marks of distinction between this and M. 

 reticulata, of which this must be a very close ally, are the smaller 

 number of the nerves in the leaves of this and the ovoid shape of its 

 rugose fruit. In its leaves this plant somewhat resembles some of the 

 species of Popowia. And, inasmuch as its inner petals are larger 

 than the outer and are vaulted, it is related to Orophea, from which how- 

 ever its numerous uvarioid stamens and unisexual habit exclude it.

 young branches tawny-pubescent, speedily becoming glabrous and 

 dark- coloured. Leaves membranous, elliptic-oblong, rather abruptly nnd 

 shortly acuminate, the base cuneate and often slightly unequal-sided ; 

 upper surface glabrous except the depi-essed, strigulose midrib ; lower 

 surface much reticulate, glabrous but with a few scattered hairs on the
