288 cxxiiiD. URTiCACE^ (Rendle). [Pouzolzia. 



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, 

 1-1 i 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 3-1-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. — AVedd. Monogr. Urtic. 403 and in DC.

Var. ahyssinica, Rendle. Stem slender, 8-20 in. high, with short branches 

 not exceeding the leaves or diffusely branched, hairy as in the species. Leaves

 shorter than the leaf. Flowers fewer but otherwise as in the species. — P.
