A species strongly characterized by its very narrow, slender, 
caudate-acuminate, thin leaves, which are supplied on the lower 
surface with rather numerous, scattered, white, shining, stellate 
scales which do not, however, form a continuous covering.

longis; capsulis depresso-globosis, 12 mm diametro, leviter ad- 
presse pubescentibus, sepalis accrescentibus, persistentibus, usque 
ad 12 mm longis et 6 mm latis. 
A dioecious shrub, 1 to 3 m high, the younger parts more or 
less pubescent, branches terete, glabrous, grayish. Leaves lan- 
ceolate, entire, chartaceous, 12 to 20 cm long, 2.5 to 4 cm wide, 
Subequally narrowed to the usually cuneate base and to the

surface dark olivaceous, slightly shining, glabrous, smooth, the 
lower surface usually brownish, sparingly pubescent along the 
midrib; lateral nerves 9 to 11 on each side of the midrib, prom- 
inent on the lower surface, distant, arched-anastomosing, the 
reticulations lax, often rather distinct; petioles somewhat pubes- 
cent, 5 to 15 mm long. Pistillate inflorescences axillary, slen- 
der, simple, up to 6 cm long, spicate or subracemose, pubescent, 
few-flowered, the bracts lanceolate, 8 to 14 mm long, 2.5 to 3

Sepals eglandular, lanceolate, acuminate, slightly pubescent, 6 
mm long, 2.5 mm wide. Petals glabrous, dark purple, 5 to 6
