Description
|
Epiphytic shrub 0.5-1 m tall, vegetatively glabrous throughout; branchlets terete. Leaf blades drying coriaceous, oblong elliptic to ovate, 5-8(-10.5) cm long, 2-3(-5) cm wide, basally rounded or broadly obtuse, apically acute to rounded, entire and with a thickened ridgelike border, 5-plinerved, the veins almost plane to moderately prominent above and slightly elevated beneath, the midvein prominently elevated beneath, the veinlets inconspicuous; petioles thick, drying corrugated, 4-8 mm long. Inflorescences axillary, usually in the axils of the upper leaves, fasciculate or obscurely racemose, 2-4-flowered; pedicels stout, 5-11 mm long, bracts minute, triangular to deltoid, 0.5-1.0 mm long, bracteoles 2, papery, ovate to deltoid, acute, 0.6-1.2 mm long borne at or a little above the middle. Flowers with the hypanthium articulate with the pedicel, prismatic to cylindric at anthesis, 3-5 mm long and distinctly 5-angled, glabrous; calyx limb suberect and about 2 mm high including the lobes, the lobes 0.5-1 mm long, triangular to broadly deltoid with acute to rounded sinuses; corolla tube thinly fleshy, cylindrical at anthesis, glabrous, 17-18 mm long, basally 3-5 mm in diameter, slightly contracted apically, bright red to scarlet, the lobes 5, deltoid to narrowly oblong, acute, 1.5-3 mm long, dark green, in- ternally whitish puberulent; stamens 10, the filaments membranaceous, ca. 3 mm long, distinct, the sacs 4-4.5 mm long with a single rigid tubule ca. 3 mm long opening by an oval cleft 2.5 mm long; style about as long as the corolla.

Note

There is now reasonable question as to the distinction of M. epiphytica from M. insignis. The primary basis for separating the two species has rested upon the separate filaments of M. epiphytica in contrast to the connate filaments of M. insignis. However populations and specimens have been encountered in Panama with connate, weakly coherent, and separate filaments. Dark green corolla lobes are often noted as occurring on the specimens with separate fila- ments but this has not been noted on the more northern specimens of M. insignis with connate filaments. It is urged that careful notes be made of the flower colors exhibited by these plants.
