softly hairy on both faces and margin, especially on the nerves 
beneath, sometimes thinly white-tomentose beneath, older leaves 
more or less scabridulous with dotted cystoliths on the upper face ; 
petioles slender, hairy, up to one-fifth the length of the leaf but 
generally less. Stipules ovate, acuminate-caudate, glumaceous, 
1-14 lin. long, with long soft hairs on the back of the mid-vein and 
margin. Inflorescence dense, few- to many-flowered, androgynous ; 
bracts small, scarious, hairy; some of the female flowers are sub- 
tended each by a larger foliaceous broadly ovate or orbicular-ovate 
reniform blunt stipulate bract, hirsute with short hooked hairs, 
which envelopes the fruit. Male flowers sessile or subsessile ; peri- 
anth 3-4-partite, segments broadly elliptic, hirsute on the back 
with short hooked hairs. Female flowers sessile ; perianth ovoid, 
densely hairy, with a narrow tubular mouth immediately above 
which the style bears the oblong red-brown stigma ; stigma shorter 
than the perianth. Fruiting perianth broadly subcompressed-ovoid, 
base shallowly cordate, sides 4-nerved, about 1 lin. long, edge narrowly 
margined except at the base, and nerves hairy. Achene dirty white, 
each subtended by a small scarious bract, or a large broadly-ovate 
leaf-like enveloping bract.—Wedd. Monogr. Urtic. 403 and in DC.
