Type in the U. S. National Herbarium, no. 715709, collected on a thinly for- 
ested hill near La Palma, southern Darién, Panama, flowers, January 25, 1912, 
by H. Pittier (no. 5478). 
This species of Miconia ranks among the largest representatives of the group 
and takes its place between M. poeppigii Triana and M. pyrifolia Naud. From 
the first it differs mainly by its leaves, these being entirely glabrous but for the 
petioles, their petioles shorter and blades longer, and by its glabrous calyx and 
pubescent stamens and style; from the second it is distinguished by its habit, 
the obscurely tetragonous branchlets, and the shape and size of the details of 
the flower. 
Miconia fulva DC. Prodr. 3: 180. 1828. 
Section Chaenanthera. A tree, reaching a height of 10 meters, the trunk with 
a basal diameter of about 30 cm. Trunk straight; crown elongate or pyramidal ; 
bark reddish. Young twigs acutely 4-angled, covered, like the petioles and 
lower face of the leaves, the rachis of the inflorescences, and the calyx of the 
flowers, with a dense coating of golden brown, stellate scales. 
Leaves membranous, opposite or 38 or 4-verticillate, petiolate, smooth and 
almost glossy on the upper face, 3-nerved from the base of the blade with 2 
marginal pseudo-nerves. Petiole angular or sulcate, deeply canaliculate, 5 to 12 
mim. long; leaf blades 7 to 23 cm. long, 1.5 to 5 cm, broad, lanceolate, subacute at 
the base, acute and long-acuminate at the apex; nerves and transverse veins 
impressed above, the former salient beneath, the latter forming with the costa 
an angle of about 68 degrees; margin obscurely sinuate, 
Panicles terminal, 10 to 15 em. long, pyramidal, the primary branches of the 
rachis angular the secondary ones in whorls of 4, subequal. Flowers pentamer- 
ous, sessile, about 4 mm. long, one opening at a time in each small cluster. 
Calyx campanulate, 2 mm. long, irregularly denticulate on the margin, covered 
outside with minute stellate scales, darker in the center. Petals 2.2 mm. long, 
1.5 mm. broad, ovate, irregularly denticulate-truncate at the tip, white. Sta- 
mens 10, 3 to 3.5 mm. long, glabrous; filaments flattened, deflexed; anthers
