An undescribed species near the preceding, with scandent, slender, flexuose, dichotomous 

 branches, the axils 1-2 in. apart ; leaves ovate-eUiptic, rounded at the base, with a shortish 

 acute or obtusulous acumen, thinly chartaceous, with margins scarcely revolute, dark 

 rubiginoiis green above, opake, with slender immersed nerves and delicate reticulated 

 veins, puberulent beneath, griseous, finely granulate, the nerves fuscous, scarcely pro- 

 minulent, 2-2^ in. long, 1-1^ in. broad, on slender, griseous, margined petioles 3 lines 

 long ; fructiferous raceme short, 9 lines long, beartug 2 follicles, horizontally divaricated, 

 thickly cylindrical, 5 in. long, 6 hnes thick; seeds many, black, compressed, rostrate, 9 

 lines long, 1 line broad, crowned by a white, erect, thick, pencil-like coma 21 lines long. 



The foUicle and seeds exactly correspond with those of A. hebecarpus, showing that it 

 belongs to this genus. 



A drawing of this species, with its fruit and seeds, is shown in Plate XXVII. b.

A species, as before stated, confounded by Miiller with A. sylvestris. It is a slender, 

 glabrous climbing plant, resembling A. elegcms in many respects. Leaves ovate-oblong, 

 obtuse at the base, shortly acuminate, glabrous, coriaceous, elegantly veined, with 

 nerves little prominent; panicle ramose, on a stoutish peduncle, bearing few flowers 

 laxly disposed, on stoutish pedicels ; sepals obtuse ; tube of corolla nearly an inch long, 

 funnel-shaped above the middle. 



No dimensions are given, either of the leaves or parts of the inflorescence.

A climbing, glabrous species, with slender substriate branches, having their axils 

 3 in. apart ; leaves oblong, with parallel sides, rounded and cordate at the base, obtuse 

 at the summit, with a short mucronate point, entire, submembranaceous, glabrous, nitid 

 above, glauco-ferruginous beneath, with divaricate nerves and very reticulate veins, 

 3-4 in. long, 1-1| in. broad, on slender petioles 4-6 lines long ; raceme axillary, on a
