in the stouter tube of its corolla, in the position of its stamens, in the presence of a 
disk, and in its smooth (not muricated) fruit.

A. DC. Prodr. viii. 364. Ad Cartagena: v. s. in herb. Mus. Brit, sine loco (ex hb. Vahl.), et sine 
flore. 
A species apparently known only to Jacquin, who describes it as a tree 15 feet high, 
of which the trunk is 6 feet long, its branches furnished with ovate-lanceolate acute, 
entire or scarcely undulated leaves, 6 in. long, the axillary cymes consisting of a broad, 
handsome mass of about 40 reddish-white flowers, on slender pedicels 3 lines long; 
calyx of 5 lanceolate-oblong, flat, erect sepals 2 lines long; tube of corolla narrowly 
cylindrical, 6 lines long, 1 line broad, a little swollen above the base, the segments 
being dolabriform, expanded, 5 lines long, 3 lines broad, sinistrorsely convoluted; 
stamens enclosed in the swollen portion of the tube; follicles 2 (one generally abortive), 
oblong, recurved, roundly obtuse at the extremity, with a lateral curving ridge on 
each side, rather large, of a reddish colour, spotted with unequal rusty blotches, 3 in. 
long, 14 in. thick, and containing many seeds, partly enveloped in yellowish succulent 
funicles. ` 
In the specimen above cited, the leaves quite agree with the description of Jacquin. 
On it is written (not by Vahl), “ Tab. citrifolia ;” but it is very different from the original 
drawing of that species furnished by Plumier. In the specimen, the young branch is 
very slender, the axils 1-1 in. apart; the opposite leaves lanceolate, acute at both ends, 
3-43 in. long, $—1 in. broad, on petioles 4-5 lines long. 
Figures of this species, in flower and in fruit, are given in Plate VIII. a.

This typical plant agrees with Swartz's description in all respects, except the character 
of the anthers, “ ovatæ,” which shape is contrary to that of any of the Tabernemontane. 
Ï have examined the anthers in the above specimen, and find them to be narrowly oblong, 
acute and shortly bidentate at the base; stamens inserted above the middle of the tube 
and quite included, on which account the species is referred to Taberna. Itis a shrub, 
6 feet high, dichotomously branched, with slender 4-angular striated branchlets; leaves 
elliptic (younger ones lanceolate-ovate), acute at the base, with an obtuse acumen, 
inequilateral, with undulated margins, green above, very opake, nerves immersed and 
veinless, sulcated on the midrib, pallid beneath, yellowish, opake, minutely granulated, 
midrib and nerves prominulent and reddish, 21-31 in. long, 1-11 in. broad, on slender 
channelled petioles 7-9 lines long, fossated at the base and conjoined by a short trans- 
verse ridge; peduncle 2 lines long, its branches 5 lines long, each bearing 4-5 flowers, on 
pedicels 2 lines long, bracteolated at the base; sepals acutely oval, imbricated, with a 
prominent green nerve and pale membranaceous margins; tube of corolla 6 lines long; 
segments 3 lines long, inequilateral, ovate at the base, linear and horizontally expanded 
on the sinister side, simply convoluted sinistrorsely ; stamens inserted below the
