262 cxxniD. URTiCACEiE (Rendle). [Urera, 



axillary ; male generally slightly exceeding the petiole, 1 J-lf in. long, 

 with a short peduncle and a few spreading branches, bearing the 

 shortly stalked flowers in small clusters ; bud 1 lin. in diam. ; perianth 

 4-partite, segments bearing dorsally a few short stinging hairs. 

 Female inflorescence ultimately longer than the male, up to 2 in. long, 

 somewhat laxly paniculate ; flowers in small sessile clusters protected 

 by tufts of short slender stin2;ing hairs ; perianth shallow'ly 4-lobed 

 with ciliolate margin, enveloping the spheroidal young ovary, the 

 large transversely ellipsoidal mass of short ferruginous stigmatic 

 hairs alone projecting ; wdth development the ovary becomes ovoid 

 and somewhat compressed ; when about 1 lin. long the upper 

 third projects from the shallowly lobed perianth, bearing the stigma 

 at the oblique tip. Fruit compressed-ovoid, enveloped except at 

 the extreme apex by the succulent perianth forming a broadly ellip- 

 soidal drupe-like structure a little over 1 lin. long. — Durand & Schinz,

Sfx^cimens collected by Swynnerton (nos. 1518 ! and 1518a !) in very young 

 male flower in the Chirinda Forest and referred by S. Moore to U. obovata, Bentli. 

 (in Journ. Linn. Soc. xl. 20()), are probably referable to U. earner oonensis. 



The South African V. Woodii, N.E. Br., is very closely allied ; the specimen 

 from Angola (Welwitsch, 0294 !) has the shorter proportionately broader leaves 

 of the South African plant.
