Rootstock none or shoi't, not creeping nor stoloniferous nor branched, 

 but producing usually numerous stems from the point where it appears 

 above ground, but no barren tufts. Stems erect, or the lateral ones 

 ascending, rather stiff, generally branched, with the pubescence in the 

 lower part rather thin, stiff, spreading. Lower leaves oblanceolate, 

 gradually attenuated towards the base into an indistinct petiole, svib- 

 obtuse; stem leaves sessile, subdecurrent, oblong, or the upper ones 

 lanceolate-oblong, acute, thickly clothed with short stiff spreading 

 pubescence. Fruiting racemes shorter than the leafy part of tlie stem. 

 Pedicels rather slender, spreading-ascending, usually not secund, all 

 •\vithout bractSj generally exceeding the calyx, the lower ones often 

 twice as long. Calyx with a few long adpressed hairs, and very 

 numerous spreading hairs, all of which are hooked-pointed, ovate-ovoid 

 and closed in fruit; segments triangular-strapshaped, divided more 

 than half-way down. Corolla limb less than twice as wide across as 

 the length of the tube, usually concave; segments not so broad as 

 long, entire. Style less than half the length of the calyx. Nucules 

 indistinctly keeled towards the apex on the face, bordered all round. 

 Plant dull green, without any lustre.
