middle of the tube; anthers as before stated; disk very short, membranaceous, in-

l. c. p. 363. In Antilles: v. s. in herb. Mus. Brit. Jamaica (Shakespear). 
De Candolle states that this is very distinct from 7. laurifolia, Linn., founded on 
Sloane's plant, differing in its more rounded, cuneated leaves, having the nervation of 
T. neriifolia, and in its much larger flowers, which are white (not yellow), upon a much 
longer peduncle, bare at its base. It is a lactescent shrub, with stoutish 4-angular 
branches, apparently much verrucated, with axils 2-1 in. apart; the opposite leaves are 
roundly obovate, euneated from the middle to the petiole, with many nearly horizontally 
patent nerves conjoined along the margin, 24-54 in. long, 1-13 in. broad, on slender 
petioles 6-9 lines long, channelled above, broadly flattened at the base, and there con- 
joined by a transverse ridge at each node; panicles opposite, on bare peduncles 2 in. 
long, terminated by 3 alternate, very odoriferous flowers, on thickish pedicels 2 lines 
long; calyx thickly coriaceous, shortly cupshaped at the base; sepals 5, equal, roundly 
ovate, convex, imbricated, yellowish green, externally papillose and poriferous, emitting 
a viscous juice; tube of corolla thickly cylindrical, 9 lines long, 14 line broad, seg- 
ments inequilaterally oblong, very expanded, 9 lines long, 4 lines broad, sinistrorsely 
convoluted; stamens said to be short and fixed below the middle of the tube,—all being 
characters conformable with Taberna. 
4. TanERNA Pórricir, nob.: Tabernemontana Póppigii, Müller in Linn, xxx. 405. In Peruvia ad 
Tocache : non vidi. 
A species with the habit of 7. Sananho, R. & P., and with internodes as long as the 
leaves, which are elliptic, obtuse at the base, acuminated at the summit, membrana- 
ceous, with 14-16 pairs of arching nerves, concolorous, 8-9 in. long, 524 in. broad, with 
petioles 84 lines long; peduncle 13 in. long, bearing 6-8 slender flowers, which in bud 
are 62-8 lines long, on pedicels 3 lines long; sepals obtusely ovate, ciliolate, with 5-7 
internal scales; tube of corolla puberulous within at the insertion of the stamens; 
ovaries obtusely ovoid, surrounded at the base by an adherent disk. 
5. TABERNA DISPARIFOLIA, nob.: ramulis tenuibus, dichotome divisis: foliis plerumque heterophyllis, 
elliptico-oblongis, imo acutis, apice in acumen longum et angustum subito constrictis, tenuiter 
chartaceis, supra viridibus, nervis tenuissimis patentim divaricatis vix prominulis, subtus pal- 
lidioribus, opacis, costa nervisque rufulis subprominulis; petiolis tenuissimis, canaliculatis, imo 
vaginatim conjunctis, limbo 12plo brevioribus: racemo laterali aut terminali, brevissimo; pedun- 
culo depauperato, 1-2-floro; pedicellis ei equilongis; sepalis oblongis, submembranaceis, imbri- 
catis, intus squamulis parvis acutis basalibus munitis: corolle tubo tenuiter elongato, medio 
angustiore, segmentis obtuse oblongis, subobliquis, quam tubus dimidio brevioribus, subreflexis, sinis- 
trorsum convolutis; staminibus versus medium tubi insertis; ovariis 2, oblongis, apice liberis, imo 
pro dimidia parte disco adnatis. In Peruvia: v. s. in hb. meo et alior. Tarapoto (Spruce 4611). 
A species having the habit and appearance of a Peschiera: the axils of its slender 
dichotomous branchlets are 3-1 in. apart; its opposite leaves 24 and 1 or 27 and 14 in.
