92 ON SOUTH- AMERICAN APOCTNACEJE. 



leaves, bearing 2 to 4 flowers 1^ in. long, on bracteolated pedicels; sepals smooth, 

 elliptic oblong, obtuse, with undulate membranaceous margins, deeply imbricated, the two 

 iaterior much narrower ; corolla salver-shaped, yellow ; tube cylindrical, twisting, 1 in. 

 long, with expanded segments inequilaterally obovate and obtuse, shorter than the tube ; 

 anthers sagittate, seated in the middle of the tube; disk fleshy, investing 2 ovaries. 

 Prof. De Candolle rightly placed this species in Malouetia, as the kind of inflorescence 

 here indicated is unknown in any plant of the Taberncemontanece, but is not uncommon 

 in Malouetia : the structure of the flower is that of this genus.

A lactescent tree, with smooth, terete branches ; leaves oblong, narrowly acute at the 

 base, acuminate, with obsoletely undulate or repand margins, membranaceous, nerves 

 remote, prominent beneath, 6-7 in. long, 2-2J in. broad, on channelled petioles 6 lines 

 long, their margins conjoined across the node by a transverse ridge ; cymes opposite and 

 interpetiolar, much shorter than the leaves; peduncle dichotomously divided into 4 

 approximated, divaricated, many-flowered spikes ; flowers the size of those of jessamine, 

 on close pedicels 3 lines long, bracteolated at the base. This species quite conforms ' 

 with M. riparia in the character of its inflorescence and structure of its flowers.

This species, with flowers like those of jessamine, evidently belongs to this genus, as 

 Kunth suspected; its opposite, oblong leaves, acute at the base, subacuminate, sub- 

 membranaceous, are 3-4, in. long, 14-18 lines broad, on petioles 3 lines long; in a 

 specimen from Turbaco (perhaps another species) they are 5-6 in. long, 20-21 lines 

 broad, on petioles 6 lines long ; peduncle 6-15 lines long, bearing several flowers on 

 slender pedicels 6-7 lines long; sepals ovate, 1 Kne long; tube of corolla 4 lines long, 

 swollen at the base, the segments being expanded, obovate-oblong, 5 lines long ; stamens 

 placed in the mouth of the tube, linear, biaristate at the base ; the 2 ovaries surrounded 

 by the disk ; style slender ; clavuncle adhering to the anthers.

The descriptions of De Candolle and Mixller accord so well together that they denote 

 identically the same species. The leaves are elliptic-oblong, acute at the base, obtusely 

 acuminate, 3-4 in. long, 10-15 lines broad, on petioles 2-3 lines long; the peduncle is 

 3 lines long, bears 4 to 7 flowers, on slender pedicels 8-10 Hues long ; sepals subulately 

 lanceolate, reflexed at their apex, 2 lines long; tube of corolla 4 lines long, constricted 

 in the middle; the segments, as large as the tube, are linear, acute, glabrous outside, 

 puberulous within; stamens partly exserted; anthers dorsally hispidulous; disk of 

 5 erect lobes; ovaries 2, hispidulous at the apex; follicles 12 in. long, 4 lines broad, 

 obtusely attenuated.
