6. M, sedoides Hiern, sp. n.

 of Sedirni ; stems pale-ashy, glabrate, fleshy -wiry, dichotomously 

 branched ; branchlets pubescent, the flowering ones elongated ; 

 leaves rosulate-fasciculate, oval, obtuse or rounded at the apex, 

 sessile or subsessUe, shaggy-hoary, -j- to |- in. long by -J to |- in. 

 broad, entire or repand-crenate, thick ; flowers bright violet in 

 colour, ^ in. long, sessile or subsessile,»in subsecund rather dense 

 often pedicellate spikes of 2- to f in. long, arranged in terminal 

 and sometimes also axillary panicles which are 1|^ to 3 in. long ; 

 calyx about -^^ in. long, hispid with thick pale hairs, shortly 

 toothed ; corolla bilabiate ; the tube nearly glabrous, narrowly 

 funnel-shaped ; the limb somewhat bearded at the back ; the

 compressed and hooded at the apex ; stamens 4, didynamous,

PtJNGO Andongo. — On the elevated rocks of Pedra Cabondo, 

 plentiful but only on the north-west side, in the preesidium, where in 

 the dry season, that is, from May to October, in its apparently dead 

 state it covers them with a very sad colour ; but in March after the 

 enlivening effect of the December rains it very pleasantly ornaments 

 these rocks with its crowds of lilac flowers ; fl. April 1857. Nos. 1629,

 a Sedum, puberulous with glandular papillae ; root tuberous ; 

 stems slender, firm, sinuous, elongated, ascending and branched 

 at the terminal inflorescence ; leaves opposite or apparently 

 verticUlate by reason of the presence of leafy axillary shoots, 

 narrowly eUiptical-oblong, narrowed at both ends, sessile or sub- 

 sessile, entire repand or pauci-denticulate, mostly secund, J^ to \\ 

 in. long by ^ to |- in. broad ; flowers violet-purplish, about ^ in. 

 long, sessile or subsessile ; verticils 2- to 4-flowered, bracteate at 

 the base, distant, arranged in spikes ^ to 2^ in. long; spikes
