Description
|
Tree 6-20 m tall; branchlets appressed puberulous when young, glabrescent, terete. Leaves elliptic to narrowly obovate, 6-26 cm long, 2.5-10.5 cm wide, acute to acuminate, cuneate to obtuse at the base, chartaceous, entire or with a few remote teeth towards the apex, drying dark above, brownish below, the midvein slightly impressed above, raised below, the secondary veins plane above and prominent below, tertiary venation prominulous below; puberulous on mid- vein above, below puberulous along the main veins and sometimes sparsely over the surface; petiole more or less puberulous, 1-3.5 cm long. Inflorescence arising from the branchlets below the leaves, paniculate, puberulous, 8-18 cm long, the flowers on short, ca. 1 mm long, pedicels or subsessile, mostly borne singly.

Flowers white or greenish, drying black; sepals broadly ovate, ciliate fringed, otherwise glabrous, 1 mm long; outer petals ovate, thick, ca. 2.5 mm long, the inner petals linear; fertile stamens 2, the filaments linear, the anther thecae broad, ca. 0.5 mm long, separated by the thickened connective; ovary ovoid, glabrous, ca. 0.8 mm long, apically truncate, the style 2 mm long. Fruit pyriform, 2.2-2.5 cm long, 1.7-2 cm wide.

ranges from Panama to western Ecuador.

Note
|
This species is similar to M. glabrata and its segregate M. panamensis. Much of the Panamanian material previously determined as M. panamensis is actually this species. The major differentiating feature between the two species is the persistent pubescence of petiole and main veins of the leaf undersurface in M. occidentalis. As here interpreted the fruit shape characters noted by Cuatrecasas are not constant.
