 glands at the base of the midrib, ferruginously opake beneath, with prominulent and reti- 

 culate veins, 3-4 in. long, lJ-2 in. broad, on deeply channelled reflexed petioles 3-4 lines 

 long ; the inflorescence is axillary, or in the dichotomy of the branches, 1 in. long, con- 

 sisting of 8 or 10 approximate flowers on a slender peduncle 3 Hues long, all glabrous, 

 upon pedicels 2-3 lines long, supported by an acutely ovate membranaceous bracteole 1 

 line long ; sepals acutely ovate, submembranaceous, 1 line long, each with three minute 

 inner basal scales ; corolla red, glabrous outside, 4 lines long ; tube 8 lines long, pilose 

 itt the throat; segments subovoid, membranaceous, 1 line long, with dextrorse con- 

 volution ; stamens partly exserted ; anthers acuminate, with 2 long, slender, parallel 

 basal prongs ; disk of 5 oblong free lobes, nearly as long as the 2 ovaries.

 bracteole of the same length ; sepals ^ line long ; tube of corolla 1 line long ; segments

The specimen above quoted is Gardner's 5012 (not Gaudichaud's, as Mi;Uer by mis- 

 take states). Its branches are fistulous, compressed, lenticellate, fuscous-reddish, with 

 axils 2-2^ in. apart, each node furnished with 3 distinct interpetiolar stipules ; leaves 

 ternate, spreading, oblong-elliptic, subacute at the base, narrower and mucronately 

 obtuse at the summit, submembranaceous, glabrous, darkish green above, with a 

 flattened fuscous midrib, and about 9 pairs of arcuated nerves, each with a small 

 concave gland within its axU, and a more or less concrete granular gland at the base of 

 the midrib, concolorous beneath, with reddish prominulent nerves and reticulated veins, 

 4i— 41 in. long, l|-2 ia. broad, on channelled lenticellate petioles 1 line long; panicle 

 terminal, somewhat spreading, 8 in. long, bearing innumerable very small flowers on a 

 peduncle bare for 7 lines, then oppositely branched at intervals of 1^ in., gradually 

 diminishing upwards, branches very slender, arcuately ascending, bare at the base for 

 some distance, bracteolated, each alternately divided, the branchlets bearing several laxly
