hairs. Leaves coriaceous, ovate to oblong-ovate, 5 to 7 cm long, 
2.3 to 4 cm wide, green on both surfaces when dry, when fresh 
deep purple beneath as are the branches and infiorescences, brit- 
tle, base rounded, apex acuminate, both surfaces scabrous from 
the short, scattered, hispid hairs; lateral nerves about 6 on each 
side of the midrib, prominent, curved-ascending, anastomosing, 
deeply impressed on the upper surface, both surfaces somewhat 
bullate; petioles 6 to 13 mm long, pubescent; stipules triangular- 
ovate, acuminate, sparingly toothed, pubescent, about 5 mm long. 
Inflorescence a somewhat leafy terminal panicle up to 18 cm 
long, rather prominently pubescent, the lower branches subtended 
by somewhat reduced leaves. Flowers numerous, somewhat 
corymbosely crowded on the branchlets, about 5 mm long, 4- 
merous, their pedicels pubescent, 5 mm long or less, the subtend- 
ing bracteoles linear-lanceolate, 1.5 mm long. Calyx 2 mm long, 
the tube ovoid, terete, 1 mm long, the teeth as long as the tube, 
‘narrowly ovate, obtuse to acute, 1 mm long. Corolla-tube 2 
mm long, the lobes narrowly ovate, obtuse, 1.3 mm long, the

Ramos & Edaio, May 7, 1917, on the forested summit of the 
mountain, altitude apparently about 1,000 meters. 
This characteristic species is described by Ramos as having 
the stems, inflorescences, calyces, and the lower surface of its 
leaves dark-purple in color, but when dry the leaves are uniformly 
greenish on both surfaces. It is well characterized by its sca- 
brous, ovate to oblong-ovate leaves, which are more or less bullate 
on both surfaces, its nerves deeply impressed on the upper sur- 
face and prominent beneath.
