Description
|
Glabrous shrub 1-3 m. tall; petioles stout, 1-3 cm. long; leaf-blades red-purple beneath, narrowly oblong to lanceolate, 12-25 cm. long, a fourth to a third as wide, acuminate, entire but ciliate, acute at the base, 3-nerved with a conspicuous pair of submarginal nerves; panicle small, 5-10 cm. long, sparingly branched; flowers sessile, secund, subtended by triangular bracts about 1 mm. long; hypan- thium subglobose, 2-2.5 mm. long at anthesis; calyx-tube very short, truncate or nearly so around the summit; petals white to pink, oblong-obovatlong, oblique; stamens isomorphic; anthers slenderly oblong, 1.7 mm. long, 2-celled; connective simple; ovary almost completely inferior, 5-celled; style stout, 2.5 mm. long, abruptly bent near the summit; stigma punctiform.

Note
|
Stern & Chambers 193 and 187, both from Pifias Bay, Darien, have recently been referred by Wurdack to M. robinsoniana Cogn., a species otherwise endemic to the Galapagos Islands. In the artificial key to the genus Miconia, this species would fall next to M. hondurensis, differing however in the quadrate branches, denser leaf blade venation, secund flowers, and eglandular stamen connective. The affinities of M. robinsoniana are with species 40-45 of Cogniaux' familial monograph, as well as with M. curvipetiolata Cogn. & GL. ex GI., M. blakleaefolia Gl., and M. transverse Gl. With such an obvious superfluity of epithets, no phytogeographic speculations concerning the apparent distribu- tional disjunction of M. robinsoniana would be valid at present.

Specimen
|
COCLE: north rim of El Valle de Anton, near Cerro Turrega, 650-700 m., Allen I74. COLON: summit of Cerro Santa Rita, 360-500 m., Allecn 5098. PANAMA: Cerro Campana, 600-800 m., Allen 2642.

|
Note
|
Allen 5098 is referred here with some doubt, since it was described by the collector as a vine and the panicle is more widely branched than in typical plants.
