 sice, in herb, meo (no. 1567 et 4628). 



A plant very distinct from Pe CandoUe's species {Gaudichaudii), having oval leaves 

 with a short very sudden acumen and long deflexed racemes ; the branches are gla- 

 brous, pallidly terete, subflexuose, striolate, verrucosely lenticellate, dilated at the axils, 

 which are 4iJ-6J in. apart, with a crenulate transverse ring of many stipuloid fleshy 

 glands ; leaves ovate or oblong-ovate, rounded and often obsoletely cordate at the base, 

 suddenly and shortly acuminate or retuse at the apex, chartaceous, with scarcely revolute 

 margins, green and glabrous above, with about 6 pairs of slender semi-immersed nerves 

 arcuately conjoined, yellowish opake beneath, subscabrid, somewhat hispidulous on the 

 prominulent midrib and nerves, 3^5 in. long, 2-3 in. broad, on patent subpuberulous 

 petioles 3 lines long ; racemes lateral and solitary at the nodes, 4-5 in. long, on a rather 

 slender subdeflexed peduncle, bare at its base for a length of 1^-2^ in., subangular, 

 subverrucose, subglabrous, subpuberulous, somewhat flexuose above and bearing many 

 alternate flowers on slender patent or reflexed pedicels IJ line apart, 4 lines long, sup- 

 ported by linear acute bracteoles \ line long; sepals oblong, acute, 2 J lines long, 2 lines 

 broad, with an inner acute 3-denticulate scale ; corolla salver-shaped ; tube 6 lines long, 

 with a faucial annular ring and 5 linear semi-exserted appendages arising from below 

 the mouth ; segments oblong, inequilateral, expanded, 3 lines long ; disk, ovaries, style, 

 clavuncle, and stigmata as in the generic character; follicles 2, immature, 4|-6 in. 

 long, very strangulately torulose.

Mus. Brit. Bahia (Lockhart). 



A species having subangular branches, at first clothed with spreading long rigid hairs, 

 afterwards scabrid ; axUs 5 in. apart ; leaves oblong-ovate, roundish and plicately re- 

 curved at the base, obtusely subacute at the summit, with a fine mucronate point, 

 margins very revolute, rigidly coriaceous, dark oKve-green above, opake, scabridulous 

 and sulcate along the fine arching nerves and reticulate veins, palish glaucous-green 

 beneath, opake, scabridulous upon the prominent midrib, nerves, and veins, 2f-6 in. long 

 1^2f in. broad, on petioles 2:|— 4 lines long ; raceme solitary and lateral at the nodes, 

 1-]- in. long, on a fuscous reflexed peduncle bearing several alternate flowers on pedicels 

 rather approximate and 2 lines long, supported by acutely ovate bracteoles 1 line long ;
