A species bearing much, the appearance of Mesechites myrtifoUa; it has extremely 

 slender scabridulous branches, pilose towards the ends ; opposite ovate-oblong leaves, 

 narrowly cordate at the base, acute and mucronate at the apex, margins revolute, cori- 

 aceous, glabrous, with immersed nerves, 6-9 lines long, 4-5 Hnes broad, on very short 

 petioles; raceme terminal, shortly pedunculate, bearing at its apex 3-4 alternate 

 flowers on pedicels 4-6 Knes long, with siibrevolute bracts 1 line long ; flowers 9-10 lines 

 long ; sepals acutely ovate, glabrous, \\ liae long ; tube of corolla 3 Hnes long, narrower 

 below the middle, swelling above ; stamens iaserted in the contraction of the tube ; 

 anthers pilose behind ; disk urceolate, with undulate margins, as long as the 2 ovaries ; 

 follicles very slender, terete, 3-4 in. long.

A species, according to Grisebach, near A. lAndenicma ; it also approaches A. Sagrcei 

 in habit. A small tree, with very slender, dichotomous, compressed, dark-red cinereo- 

 glabrous branches, with axils 3 lines apart; opposite lanceolate leaves, cuneately nar- 

 rowed upon the petiole, roundly obtuse and emarginate at the apex, chartaceous, with 

 revolute margins, glabrous, nitid, dark green above, corrugulate, sulcate along the 

 midrib, opake and dealbate beneath, with immersed darkish nerves and reticulated veins 

 1-lf in, long, 5-6 lines broad, on slender channelled petioles 1 J line long ; raceme lateral, 

 nearly as long as the leaves, depauperated, with 2 flowers on slender pedicels 4f lines 

 long ; flowers rose-coloured ; sepals ovate, obtuse, 2 lines long ; corolla 9J lines long ; tube 

 contracted below the middle; segments paler, rhombic ovoid, 3^ Hnes long ; stamens seated 

 in the contraction of the tube ; anthers hispidulous behind; follicles 2, erect, terete, slightly 

 arcuate, 4f in. long, 1-j line thick ; seeds many, pale brown, linear oblong, compressed, 

 with white verrucxilar stripes on the back, pale (with a raphe) on the ventral side, 3 lines 

 long, with a simple coma of the same length. 



This species is referred by Benth. & Hook. (Gen. ii. 725) to Mandevilla ; but this refer- 

 ence cannot be maintained. 



23. Angadenia Havanensis, nob. : Rhabdadenia Cubensis, Miill. I.e. p. 435. In Cuba, Saltadero (Lin- 



den 1716) : non vidi. 

 A species near A. Cubensis, with extremely slender, fuscous, patently pubescent 

 branches ; leaves linear-lanceolate, suddenly contracted and obtuse at the base, acute 

 at the apex, membranaceous, dark olive-green above, subglabrous, rufescent beneath, and 

 pubescent on the midrib, l-lj in. long, 2-3 lines broad, on petioles 1 line long ; raceme 

 lateral, subglabrous, longer than the leaves, pedunculate, bearing above 6-8 flowers on 

 alternate slender pedicels 4f lines long, with a minute acute basal bract ; sepals ovate, 

 acute, 6 lines long, imbricate, with 1 or 2 subulate inner scales ; corolla 1-1:| in. long ; 

 tube narrow below the middle, campanulate above; segments inequilaterally oblique, 

 near half the length of the tube; stamens inserted in the contraction of the tube;
