or slightly acuminate at the apex, ciliate on the margins; receptacles 
themselves subglobose, glabrous, strongly umbonate when dry, 6-8 mm 
long, 5-6.5 mm in diameter, the ostiole showing 6 or 7 rather conspicuous 
teeth; one set of receptacles containing female flowers only, the other, 
borne sometimes at least on the same branches, with male, gall, and im- 
mature gall flowers : male flowers about 20-25 in each receptacle, forming 
a band about 0.5 mm wide below the ostiole, on pedicels 0.6-0. 7 mm long; 
perianth-segments 5, separate, blackish-purple, oblong, 0.7 mm long, 0.4 
mm wide, acuminate at the apex, rounded at the base, pubescent within 
at the base, fleshy; stamens 2, the filaments usually united for about 0.2 
mm, and the lower and smaller anther then very nearly sessile, the upper 
and slightly larger anther with a filament in all 0.5 mm long, but rarely 
in the same receptacle with filaments entirely free and anthers attaining 
a length of 0.5 mm, anther-cells 2, oblong, truncate or rounded at either 
end : supposed gall flowers sessile, the perianth very inconspicuous, sheath- 
ing the very base of the stalk of the ovary; the stalk 0.7-0. 8 mm long; 
the ovary angled, irregular in outline, about 1 mm in length and diameter ; 
the stigma small, lateral or subterminal : minute flowers also present, 
with flattened ovaries 0.3 mm in diameter, nearly oblong in outline, 
supposed to be rudimentary gall flowers : female flowers in receptacles 
slightly longer-pedunculate than the male, sessile, perianth lobes 4, 
broadly ovate, 0.7 mm long, 0.5 mm wide; ovary sessile, obovoicl, 1.7 mm 
long, 1.2 mm wide, the style attached to the back nearly halfway to the 
top, 1.3 mm long and then divided into 2 diverging arms' about 0.5 mm 
long. 
Variable in habit, described as a vine, a bush, and a tree 6 nr high 
with a stem 10 cm in diameter ; bark of the older branches gray, of the 
younger brownish, striate, somewhat nodose, glabrous or very nearly so; 
leaves with minutely pubescent petioles 2-6 mm long, the lamina lanceo- 
late, elliptic, oblanceolate, or obovate, 4-11 cm long, 1.7-3. 6 cm wide, 
acute or rounded at the base, at the apex rounded, or shortly or moderately 
blunt-acuminate, revolute on the margins, coriaceous, glabrous, bluish- 
or yellowish-green on the upper surface, brownish and densely though 
minutely papillose beneath ; midrib alone of the veins prominent, all 
other veins very thin, and obscure on both surfaces, primary veins on 
each side probably 7-10.
