264 cxxiiiD. URTiCACE^ (Rendle). \Urera, 



the petiole, with numerous stinging hairs. Flowers sessile or sub- 

 sessile, just over J lin. long; perianth sac-like, completely enveloping 

 the ovary which is ovoid with a definite oblique apex which projects 

 through the mouth of the perianth and bears a short densely peni-

 in the succulent perianth, the short beak-like oblique apex alone

15. U. repens, Rendle. A low herb with a persistent thin woody 

 glabrous creeping stem up to IJ lin. in diam., rooting at the nodes. 

 Leaves long -stalked, cordate, somewhat abruptly shortly acuminate, 

 margin very obscurely crenate, 3-nerved at the base, with 4 pairs of 

 opposite upcurving nerves above ; nerves slender and somewhat 

 prominent beneath, as are the slender cross-unions ; 2J-4 in. long 

 and slightly wider, thinly membranous when dry, glabrate, both 

 faces with visible cystoliths, which are shortly linear on the nerves 

 and veins and dot-like between ; petiole slender, 4-6 in. long, longi- 

 tudinally furrowed when dry, puberulous. United stipules short, 

 ovate, acuminate, persistent, 2 lin. long. Male inflorescences corym- 

 biform, springing from leafless nodes ; peduncles slender, as long as 

 the petioles and similarly puberulous ; flowers subumbellate at the 

 ends of the slender branchlets ; pedicels 1-1 J lin. long, glabrescent, 

 with a minute basal bract ; buds depressed globose, about f lin. in 

 diam. ; perianth deeply 5-partite, segments concave, ovate, with a 

 few short stinging hairs on the back ; rudimentary ovary short, 

 inverted-turbinate. Female flowers and fruit unknown. — Laportea 

 repens, Wedd. in DC. Prodr. xvi. i. 81.

The characters of the foliage suggest Urera rather than Laportea, especially 

 the form and arrangement of the cystoliths. 



Imperfectly known species. 



16. U. Pischeri, Engl. Pfl. Ost-Afr. C. 162. A climber with stem 

 thinly hairy. Leaves large, ovate, rather obtuse, margin with very 

 short broad teeth, 6 in. long, 4f in. wide, sparsely hairy on the upper 

 face, densely and softly hairy below : petiole half as long as the leaf, 

 thinly hairy and bearing towards the apex long linear or forked out- 

 growths. Female inflorescence forming a rather dense panicle 

 longer than the petiole.
