from the extreme gracefulness of its slender pendulous open 

 racemes, and the regular shape of its peculiarly-formed leaves. 

 Sometimes the leaves of other and allied species assume a con- 

 traction in the middle, giving them a kind of sub-panduriform 

 shape, but none are so deeply and so regularly lobed as these. 

 This character pertains alike to both male and female plants, 

 although the leaves of the male plant are very much smaller 

 than those of the female. 



4. M. truncata, sp. uov. 



A slender rambling climbing twining shrub, rising to 8ft.- 

 9ft. among shrubs and trees. Branches very long and slender, 

 flexuous, closely twining, thickly pubescent ; hairs very 

 short, red. Fern. : leaves membranous, numerous, scattered, 

 sometimes fascicled in pairs, broadly oblong, ^in.— |in. long, sides 

 straight, tip obtuse rounded rarely apiculate, base truncate ; 

 dull pale-green, glabrous, wavy, opaque ; margins entire, red ; 

 veined, veins slightly anastomosing. Petiole very slender, 

 almost capillary, 4-5 lines long, puberulous. Cauline bracts 

 long, truncate, margins entire. Flowers disposed in simple 

 short racemes i^in.-lin. long, and 5-12-flowered ; raceme 

 vaginant ; sheaths small, reddish, funnel-shaped, oblique, wdth 

 1 long stout excurrent nerve ; margins finely serrate. Pedicel 

 short, scarcely longer than sheath, with a single narrow^ line 

 of pubescence. Perianth small, shorter than nut, whitish or 

 very pale-green, very membranous, free ; lobes oblong, obtuse, 

 appressed and spreading, not cut to base, 1 -nerved ; veins 

 finely reticulated {sub lente). Nut very small, about 1 line 

 long, sub-rhomboidal or broadly lanceolate, trigonous, sides 

 equal, angles obtuse, ridges irregular, brownish-black, dull not 

 glossy. Style 0. Stigmas 3, large, flabellate-orbicular, spread- 

 ing, plumose, reddish. Male : leaves smaller and slightly 

 contracted at the middle. Flowers both axillary and terminal 

 in simple short racemes -J-in.-lin. long, 8-15 on a raceme, 

 usually a single raceme in a sheath ; pedicel very short, 

 scarcely extending to mouth of sheath. Perianth-lobes ob- 

 ovate, cut nearly to base; tips rounded, incurved. Stamens 

 exserted, spreading, straight and slightly flexuous ; anthers 

 white, sub-orbicular-elliptic, margined. 



Hah. In same locality as the preceding species, M. trilo- 

 bata ; but neither of these species was commonly observed, 

 while the larger species — "if. adpressa, Lab." (but ?) — abounds, 

 attaining to a very large size, and forming impassable thickets; 

 1888 : W. C. 



Obs. This species is a more slender and implexed plant, 

 and rises considerably higher, than 31. trilobata : its smaller 

 and fewer flowers, and entire strictly truncated and smaller 

 leaves, arrest the attention at first sight when compared, and
