v. s. in herb. Mus. Brit. Jamaica (Houston, in fructu). 
A slender, low, weakly species with twining glabrous or scabridulous branches, the 
axils being 2 in. apart; leaves subpatently opposite, elliptic-ovate, obsoletely subcordate 
at the base, subacute and mucronate at the apex, chartaceous, with subrevolute margins, 
green above, opake, with immersed divergent nerves, yellowish opake beneath, with 
prominent red midrib and nerves, veins transversely reticulated, 14 lines long, 7 lines 
broad, on slender petioles 13 line long ; inflorescence terminal or axillary, on a peduncle 
9 lines long, bearing beyond several alternate flowers on pedicels 23-3 lines long ; sepals 
linear acuminate, 14 line long; corolla salver-shaped, rose-coloured ; tube slender, a little 
swollen in the middle, 6 lines long; segments dolabriform, 5 lines long, 3 lines broad, 
rotate; stamens enclosed in the middle of the tube; follicles 2, on a peduncle 4 lines 
long, extremely slender, terete, substriate, torulose, 6 in. long, 14 line broad, enclosing 
several comose seeds. 
Müller united into one species this and the following; but this differs in its larger and 
more ovate leaves, and its corolla with a tube more than double the length of the 
other. 
A drawing of this species, in flower and fruit, showing its floral analysis, is given in

v. s. in herb. Mus. Brit. Cuba (La Sagra 142 in flore, Wright 1662 in fructu). 
A climbing species with scabrid slender branches, filiform above, with axils 2-12 in. 
apart; leaves patently opposite, rarely ternate, ovate-oblong, rounded and obsoletely 
cordate at the base, rounded and mucronulate at the summit, subcoriaceous, with revo- 
lute margins, green above, with obscure immersed nerves, beneath yellowish-opake, with 
very prominent midrib and diverging nerves (about 8 pairs), 9 lines long, 3-5 lines 
broad, on slender petioles 4 line long; raceme axillary, short, on a peduncle bearing 
2-3 rose-coloured flowers on very slender pedicels 2 lines long ; sepals acute, 1 line long; 
corolla hypocrateriform ; tube narrowly cylindrical, 12 lines long, slightly ventricose 
above the middle; segments inequilaterally ovate, very rotate, 6 lines long, 4 lines 
broad, with dextrorse convolution; stamens inserted in the middle of the tube; disk of 
5 oblong obtuse lobes, shorter than the ovaries; follicles 2, subcompressed, torulose, 
9 in. long, 2 lines broad, on a peduncle 6 lines long.

A species differing in all respects from M. torulosa, especially in the size and shape of 
its leaves and in its inflorescence. The branches and branchlets are very slender, 
scandent; the leaves subapproximate, appearing remote from the falling-off of the
