deorsum angustatis, basi cuneatis, breviter petiolatis, margine 
crenato-dentatis, nervis utrinque 6 vel 7, perspicuis; inflorescen- 
tiis axillaribus, sessilibus vel breviter pedunculatis, plerumque 
3-floris, floribus sessilibus, dense rufo-ciliatis, bracteis binis ob- 
longo-ellipticis ad ovatis ciliatis 10 ad 12 mm longis deciduis 
instructis; calycis dense ciliatis, 9 ad 11 mm longis, lobis lan- 
ceolatis, caudato-acuminatis, tubo subaequantibus; ovario glabro; 
fructibus oblongo-cylindraceis, usque ad 11 mm longis, glabris. 
An erect, suffrutescent, usually unbranched plant, or sparingly 
branched from the base, up to 35 cm high, the stems 2 to 3 
mm in diameter, straw-colored, glabrous except at and below the 
nodes where they are conspicuously ciliate with castaneous, 
elongated, jointed hairs. Leaves opposite, those of each pair 
subsimilar in shape, but one usually about one-half as large as 
the other, chartaceous, oblanceolate to oblong-oblanceolate, 6 to 
12 cm long, 2 to 3.5 cm wide, acute, narrowed below, base cu- 
neate, margins crenate-dentate and usually conspicuously ciliate, 
the upper surface olivaceous, the lower pale, both surfaces 
conspicuously ciliate with dark-brown, spreading, elongated, 
jointed, rather stiff hairs, these widely scattered on the upper 
surface, mostly on the midrib, nerves, and reticulations beneath; 
lateral nerves 6 or 7 on each side of the midrib, prominent as 
are the lax reticulations; petioles ciliate, 5 to 12 mm long. Inflo- 
rescences axillary, the flowers few, umbellate or fascicled, the 
peduncles up to 4 mm long, ciliate, or wanting, the two bracts 
subtending the flowers oblong-elliptic to ovate, ciliate on both 
surfaces, 10 to 12 mm long, 5 to 10 mm wide, sessile, deciduous. 
Flowers sessile, usually three in each inflorescence. Calyx 
densely ciliate, the tube 5 to 6 mm long, the lobes lanceolate, 
caudate-acuminate, 4 to 5 mm long. Corolla densely ciliate. 
Disk glabrous, crenulate, 1 mm high. Ovary and style glabrous. 
Fruit oblong-cylindric, glabrous, 8 to 12 mm long, 5 mm in 
diameter.

along streams at low altitudes. : 
A species strongly characterized by its indumentum, the 
rather stiff, jointed hairs up to 3.5 mm in length being brown 
to castaneous in color, occurring on the stems near and below 
the nodes, both surfaces of the leaves, and on the petioles, bracts, 
calyces, and corollas. It does not appear to be closely allied to 
any previously described form.
