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, suff rutescent, 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. 



Mindanao, Zamboanga District, Mount Tubuan, Bur. Sci. 

 36655 (type) , 36689 Ramos & Edano, October, 1919. In forests 

 along streams at low altitudes. 



A species strongly characterized by its indumentum, the 

 rather stiif, 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.
