The stoutish branchlets, at their leafless nodes, 3-5 lines apart, are annulated by a 
curved ridge; the leaves, unequal at each node, are 4 and 2 in. long, 1$ and 1} in.

26. PESCHIERA ACUMINATA, nob.: Tabernemontana acuminata, Müll. in Linn. xxx. 406. In Bolivia 
(Cuming 121) : non vidi. 
A species said to be near P. Gaudichaudii, P. Lundi, P. fuchsiefolia, and P. affinis. 
It has smooth branches, with internodes three times as long as the leaves, and dichoto- 
mous, compressed, glaucous-green branchlets; leaves oblong lanceolate, acute at both 
ends, membranaceous, with about 12 pairs of divergent nerves, 2-33 in. long, 93-12 lines 
broad, on petioles 2-3 lines long, scarcely conjoined across the nodes; corymbs in the 
dichotomies of the branchlets, 3-fasciculate, each branch twice trichotomously and 
densely divided, 18-25-flowered, glabrous, 1-13 in. long; peduncles short; flowers in bud 
64 lines long; bracts large, 2-3 lines long, 4 line broad; sepals erect, linear lanceolate, 
blunt at the point, with a recurving margin, each with an inner basal 4-5-lacinulated 
scale; tube of corolla in bud twice the length of the calyx, distinctly swollen near the 
base, and there staminigerous on a pilose ring; disk none; ovaries 2, obtusely ovoid, 
about as long as the style. All these characters are obviously those of Peschiera.

prominulis, subtus opace pallidioribus, ochraceis, costa nervisque prominulis ; petiolis tenuiter canali- 
eulatis, imo linea curvata transversali conjunetis, limbo 12plo brevioribus: paniculis axillaribus, 
oppositis, folia superiora zquantibus; pedunculo petiolo triplo longiore, bis dichotome diviso, ramis 
huic :equilongis, 2-3-floris, cum bracteis oblongis margine membranaceis ; pedicellis gracilibus, medio 
bracteolatis; sepalis parvis, acute oblongis, submembranaceis, ciliatis, singula squamula lata pluri- 
dentata intus munitis ; corolle tubo anguste cylindrico, infra medium sensim latiore, glabro, seg- 
mentis dolabriformibus, brevioribus, sinistrorsum convolutis, intus pubescentibus; staminibus paullo 
supra basin insertis; disco nullo; ceteris ut in praecedentibus. In Peruvia: v. s. im hb. meo

In my specimen, only the upper leaves are present, on axils 4—6 lines apart; they are 
13-2 in. long, 2-1 in. broad, on petioles 2 lines long; the peduncle is 4-5 lines long, its
