NEW GAMOPETAL^ FROM THE SOUTH CAMEROONS 229 



Allied to p. nigrescens Afzel., but our species is much more 

 slender, with smaller flowers and differently-shaped leaves.

 plus minus 9 cm. x 4 cm. 



Bitye : February 20th, 1915. Bates 710 ! 



Keadily distinguished from the type specimens by the markedly 

 oblong shape of the relatively narrower leaves. 



BORAGINACEJ^.

Frutex ramulis sparse novitatibus densius subappresse pilosis. 

 Folia firme chartacea, elliptica 10-20 cm. x 1-8 cm., acutissima 

 longe acuminata, utrinque nisi in venis proesertim central! sparse 

 rufo-hirta glaberrima, petiolo validiusculo nigrescente ± 1-5 cm. 

 longo rufo-piloso. Flores in cymis paucifloris laxiusculis fusco- 

 tomentosis in ramulis terminalibus ; cahjx extus fulvo-tomentosus 

 alte sulcatus 14 cm. longus, dentibus triangularibus 4-5 mm. 

 longis: corollce glabrae tubus vix calycem excedens 1-5 cm. longus,

 1 cm. exsertte. 



Bitye : shrub at edge of rubber-field, December 1st, 1914. 

 Bates 638 I 



This species is clearly allied to C. Dusenii Glirke, but is readily 

 distinguished by the hairy branchlets, short calyx-lobes, and 

 corolla-tube scarcely exserted from the calyx. 



ACANTHACE^. 



Brillantaisia majestica sp. nov. 



Herbacea, necnon caule ad multos pedes attingente, suberecta— 

 caule insuper pubescente desuper glabrescente. Folia lanceolata

 obtusa, nonnunquam in petiolitm tenuiusculum appresse pube- 

 scentem decurrentia, supra in vena centrali appresse alitor sparse 

 pilosa, subtus sparsissime nisi in venis densiuscule pilosa, margine 

 subintegra. Cymuloi in rachide elongate distantes sessiles, spicam 

 terminalem formantes : bractece anguste spathulatae ± 6 mm. 

 longee pilis longiusculis instructtp. Calycis lobi lineares fere ad 

 1 cm. longi acuminati acutissimi sparse appresse pilosi nee glandu- 

 lares : corollce extus griseo-pubescentis tubus 1-5 cm. longus, labia 

 2-8 cm. longa, inferior 2-3 cm. latum. 



Buea, by path, 3500 ft. December 31st, 1915. Bates 817 ! 



Allied to the eastern B. madagascariensis T. Anders., but 

 readily distinguished by the small spathulate bracts and acute, 

 eglandular calyx-lobes. 



Macrorungia Batesii sp. nov.

 ad 27 cm. x 11 cm., margine distante crenato, sub-elliptica
