The following new varieties and species have been met with in 

 the course of elaborating the family for the Flora of Tropical 

 Africa. A number of species of the genus Urera have been already 

 described in this Journal (1916, p. 368). 



Flel'rta tjrticoides Engl. var. glabrata, var. nov. Planta 

 pilis urentibus deHexis munita sed a specie differt indumento hispidulo 

 nisi in inllorescentia deficiente. 



Hah. Mt. Kilimanjaro ; Marangu at 8700 ft. Volhens, 980 ! 

 Herb. Mus. Brit. 



Apparently a geographical forin ; the species occurs in the 

 Cameroons. 



Pile A tetraphtlla B1. var. major, var. nov. Herha habitu 

 speciei similis sed omnino major. Caules e basi profuse radicante 

 usque ad 4 dm. alti et 3 mm. crassi, internodiis 6-13 cm. long., ramis 

 elongatis suberectis. Folia in caule robusto 4'5-6 cm. long., 2*5- 

 5 cm. lat., in ramis et caulibus debilibus minora. Inflorescenticd 

 2 '5-3 cm. long. 



Rah. Cameroons ; Buea at 7000 ft., Preuss, 1001 ! Herb. Mus. 

 Brit. ; Herb. Kew. 



ELATOSTEMiiA Welwitsciiii Engl. var. CAMEROONENSE, var. nov. 

 Herha quam in specie major foliis majoribus sessilibus vel interdum 

 breviter petiolatis, usque ad 12 vel 15 cm. long, et 4*5-6 cm. lat. ; 

 nervis 2 lateralibus basalibus ssepius ultra laminae medium extensis, 

 eo in latere angustiore supra basm ineunte. 



Hah. Cameroons ; Johann-Albrechtshohe, Staudt, 839 ! West 

 of Buea, Preuss, 607 ! Fernando Po ; Clarence Peak, at 4000 ft., 

 Mann, 632 ! Herb. Kew. ; Herb. Mus. Brit. 



The Cameroons specimens were originally distributed as a distinct 

 species, E. kamerimense Engl, but Engler subsequently referred 

 them to his E. Welwitschii (see Engl. Bot. Jahrb. xxxiii. 125).
