A most distinct little shrub, wbicli is said to be the only fire- 

 wood on the highest mountain-top of the Drakensbergen. It 

 resembles in habit E. calvescens DC. and E. muUiJidus DC, but 

 is well characterized by its undivided leaves.

 altus ; caule stricto 4-angulari, pilis stellatis tomentosulo ; foliis 

 oblongis vel obovato-oblongis obtusis, crenatis, basi in petiolum 

 perbrevem attenuatis, sessilibusve, utrinque pilis stellatis tomento- 

 sulis, superne nunc demum subglabrescentibus, floralibus sensim 

 decrescentibus patentibus ; spica laxa, elongata, verticillis dissitis 

 2-4-floris ; floribus roseis subsessilibus ; calyce campanulato pilis

In regione austro-orientali : In clivis graminosis montis "Mont 

 aux Sources" in terra Orange Free State, alt. c. 8000 ped., Jan. 

 1896 ; J. Thode, 



8. nigricans Bth., 8. simplex Schltr., and 8. sessilis Giirke form 

 so distinct a group in habit that they might well be placed together 

 in a section, 8implicia. Our species differs from the others by its 

 leaves, the indument of the calyx, and the purple flowers.

 erecta vel adscendens spithamsea, plus minus ramosa ; ramis tereti- 

 usculis, laxe fohatis, puberuHs, vulgo tenuibus ; foliis anguste

 lanceolata linearibus, subrecurvis, glabris, nunc flores excedentibus, 

 nunc ?equantibus ; calyce ovato, membranaceo, 1*5-2 mm. longo ;
