neath, with immersed nerves, 2-4 in. long, 3-4 lines broad, on stoutish pilosulous petioles 

 1-2 lines long ; raceme lateral, 1-1^ in. long, pubescent, bearing 4-5 alternate flowers 

 on pedicels 6 lines long, supported by linear setiform bracteoles; sepals lanceolately 

 subulate, 1^ line long, with an inner 3-dentate scale ; corolla handsome, dark-red ; tube 

 2 in. long, narrowed at the base for half its length, thence enlarged into a broad funnel- 

 shape, glabrous, its mouth yellow ; segments violaceous, rhomboidally oval, inequi- 

 laterally oblique, subdolabriform, crispate, 4 lines long and broad ; stamens seated on 

 a niveously pilose ring in the contraction of the tube ; anthers membranaceous at the 

 apex, obtusely bifurcate at the base ; disk urceolate, 5-sulcate, margin 5 -notched, sur-

A distinct species, with twining, very slender, striate, subpuberulous branches, with 

 prominent transverse axils 4 in. apart ; leaves lanceolately oblong, very much narrower 

 towards the base, which is shortly and narrowly cordate, with a long, very acuminate, 

 subciliate summit, rigidly chartaceous or subcoriaceous, with revolute margins, glabrous 

 and polished above, of a deep olive-green colour, corrugulate and sulcate along the 

 hispidulous, very slender, immersed midrib, nerves, and veins, fulvously opake and 

 pruinosely velutinous beneath, with prominent slender midrib, nerves, and reticulated 

 veins, 2|-3^ in. long, |-1 in. broad, on villous petioles 4 lines long; raceme lateral, 

 1^ in. long, on a peduncle as thick as the branch, 6 lines long, bearing above about 

 12 alternate flowers of a pale-rose or yellowish colour, pubescent outside, about the size 

 of those of M. versicolor.

This species certainly does not belong to Amblyanthera, but is congeneric with all the 

 preceding. It is a climbing plant, with extremely slender, twining, reddish, hirsutulous 

 branches; its axils, 3-4 in. apart, are furnished with 2 small acute stipules on each face; 

 expanded opposite leaves, oblong-ovate, cordate at the base, suddenly or more gradually 

 acute and cuspidate at the apex, submembranaceous, pale or darker green above, opake, 

 scabridulous and hirsutulous on the midrib and nerves, beneath incano-pallid or ochra- 

 ceously opake, shortly or obsoletely velutinous, with a reddish prominent midrib, pro- 

 minulent fine nerves and reticulated veins, 2-33- in. long, 1-1^ in. broad, on pubescent 

 petioles 3-4 lines long ; raceme lateral, nearly as long as the leaves, on a peduncle 

 as slender as the branch, 6 lines long, charged above with about 14 alternate flowers on 

 pedicels from 1^ to 6 lines long, supported by slender lanceolate bracts 1| line long ; 

 sepals acute, IJ line long, with an inner rhombic, 8-denticulate scale ; corolla white, 

 of a yellowish, roseate or purplish hue, all cano-pubescent outside ; tube 16 lines long, 

 narrowed at the base for the length of 9 lines, campanular above ; segments rhomboidally
