Suffruticosa, erecta, simplex vel parce ramosa, usque ad 50 cm alta, 
omnibus partibus plus minus brunneo-ciliatis ; foliis inaequilateraliter 
obovatis vel anguste obovatis, base angustatis oblique leviter cordatis,

An erect suffrutescent plant 30 to 50 cm high, simple or sparingly- 
branched, all parts more or less ciliate with long brown hairs, the younger 
parts densely so. Leaves obovate or narrowly obovate, 6 to 10 cm long, 
3.5 to 6 cm wide obliquely inequilateral, narrowed to the obliquely and 
slightly cordate base, the broader side rounded, the other acute, apex 
acute, margins irregularly and coarsely sinuate-lobed, the lobes acute, 
the sinuses broad, shallow, both surfaces ciliate-setose, the nerves on the 
lower surface densely so ; basal nerves about 5, the outer ones very short, 
the lateral nerves above the basal ones 3 or 4 on each side of the midrib ; 
petioles 5 to 12 mm long, densely ciliate-setose with brown hairs ; 
stipules oblong-ovate, acuminate, ciliate, about 8 mm long. Panicles 
narrow, few-flowered, about 3. cm long, ciliate, solitary in the upper 
axils, the lower one or two flowers female, the upper ones male; bracts 
prominent, oblong-ovate, acuminate, somewhat ciliate, membranaceous, 
8 to 10 mm long, the upper ones smaller than the lower ones. Male 
flowers apparently pili^their pedicels slender. Sepals 2, ovate, obtuse, 
9 to 10 mm long. Petkp none. Stamens about 25. Capsules, including 
the wings, obovate, about 12 mm long, 15 mm wide, equally 3-winged,
