116 ON SOTJTH-AMEEICAN APOCTNACE^. 



Rubinequilateral, pubescent, eiliato-denticulate on the margins, 4 lines long; corolla 

 4 lines long, tubular, with a border of 5 ovate-oblong, nearly equilateral segments dex- 

 trorsely convolute in aestivation ; stamens seated a little above the base of the tube on 

 short pubescent filaments; anthers hairy behind, included, and nearly as long as the 

 tube; disk of 6 obtusely ovate truncated lobes, as long as the ovaries; style short, 

 incrassated at its summit by a cylindrical clavuncle, having a 5-cleft indusium at its 

 base ; stigmata 2, shortly rounded ; 2 foUieles, spreading, terete, pointed, glabrous out- 

 side. A species well known to the natives under the name of " quUmay," being used to 

 produce sneezing.

Captain Bang's plant does not appear to differ from that of Lochler, as described by 

 Miquel. The branches are dark red, terete, scabridly granulous, not dilated at the axils, 

 which are 1-lJ in. apart ; leaves opposite, in equal pairs, but the pairs vary in size, the 

 lower ones largest, they are elliptic, narrower and obtuse at the base, acuminate and 

 mucronate at the summit, rigidly chartaceous, with very revolute margins, green above, 

 glabrous, subrugulous, flavidly opake beneath, punctate-rugulous, hairy on the midrib 

 and 8 pairs of ascending prominulent nerves, scabridulous to the touch ; the pairs of 

 leaves are respectively 2^, If in. long, 6, 11 lines broad, on slender, patent, puberulous 

 petioles 4-6 lines long; flowers solitary in the opposite axUs, on slender pedicels 

 4-6 lines long, each bearing about 3 pairs of opposite bracteoles ; sepals linear, acute, 

 very membranaceous, subglabrous, or ciliolate, 2J lines long, f line broad, with alternate 

 acute inner scales ; tube of corolla 3^ lines long ; segments oblong, 3^ lines long, 2 lines 

 broad, with simple dextrorse convolution ; rest as in the other species. Miquel attributes 

 to it 2 follicles, erect, subtorulose, acute at each end, 3 in. long.

A plant evidently congeneric with the Uchites piarmica of Poppig. It has a stoutish, 

 terete, subtomentous trunk, with climbing thickish branchlets covered with fuscous 

 pilose hairs, and with distant internodes ; the opposite large leaves are oblong, slightly 

 cordate at the base, with a short narrow acumen, membranaceous, of a dark olive hue, 

 with subrevolute margins, opake on both sides, glabrous, with 10 pairs of divaricate 

 nerves arcuately conjoined near the margins, without any apparent veins, 10-12 in. long, 

 4-5| in. broad, on petioles l|-2 in. long ; inflorescence in opposite axils, as long as the 

 petioles ; peduncle 3 lines long, supporting 8 slender pedicels 5|-7| lines long, covered 

 with from 16 to 20 linear-subulate bracts 3 lines long, the last 5 alternate with the sepals, 

 all clothed with velvety tomentum, and terminated by a single flower, 2-2J in. long; 

 sepals linear-subulate, pubescent, 4-5 lines long, each with an internal basal tridentate 

 scale ; corolla white, with a cylindrical tube constricted below the middle, with a border
