Different as the present plant appears, at first sight, from the Wigandia Caracasana figured in the Bot.
Begister, tab. 1966, yet the inflorescence and the structure of the flowers are so similar, that without mature
fruit we dare not venture to separate it. It is quite shrubby, the glabrous stem exuding a gum-resin. Leaves
3-4 inches or more long, alternate, coriaceous, elliptical-lanceolate, tapering gradually into a short petiole,
quite entire, above glabrous, rather indistinctly reticulated with depressed veins; below strongly reticulated
with prominent veins, which are rendered more conspicuous by the areolæ being filled with very short
whitish down. In two or three of the upper leaves, and at the apex of the branch, the small flowers, (scarcely
more than half an inch long) are collected into dense capitate circinnate racemes. Corolla infundibuliform,
thrice as long as the deeply divided linear-oblong calyx-segments. Stamens included. Filaments unequal,
inserted below the middle of the tube, and then decurrent to the base of the tube ; the decurrent portion
alone slightly hairy. Anthers of two oval cells, not mucronate. Ovary ovate, slightly hairy, with no evident
hypogynous disk, 1-celled, with two opposite parietal placentæ ( ^ ) , resembling two T’s, to the free edges
of which several ovules are attached, exactly as in W. Caracasana (see Dr Lindley’s excellent figure above
quoted.) Styles 2, nearly as long as the filaments. Stigmas capitate, depressed at the top.
