The above plant, collected by me in 1836, corresponds with the description given 

 by MiiUer of the Cape-Prio plant, from nearly the same locality. It is a rather low 

 shrub, with glabrous, pallid, striate, often flexuous branches, with more or less approxi- 

 mate axils 5— 2 in. apart, much incrassate and charged with several acute warty glands 

 between the petioles ; leaves broadly ovate or oblong, subacute and plicate at the base, 

 roundish and suddenly contracted at the summit into an acute acumen 2 lines long, 

 chartaceous, with thin, subrevolute margins, fuscous green and very opake above, with 

 semi-immersed fine nerves, opake and reddish ferrugiuous beneath, the nerves being 

 scarcely prominulent. If- 3 in. long, 1-lf in. broad, on slender petioles 6-9 lines long ; 

 racemes 2, terminal, on bare peduncles ^-1 in. long, bearing upwards about 7 alternate 

 flowers, on spirally twisted pedicels, 3 lines apart and 2^-4 lines long, with a small, acute, 

 deciduous bract ; sepals acuminate, 2 lines long, with pellucid margins ; tube of corolla 

 1^ in. long, narrowly contracted and scarlet at the base for a length of 5 lines, broadly 

 funnel-shaped and paler above, with membranaceous segments, rhomboidally dolabriform, 

 mucronate, 6-7 lines long, and of a rose colour; stamens inserted in the constriction 

 of the tube ; filaments niveo-tomentose ; anthers cohering, of a reddish colour, with 2 

 basal, obtuse, parallel prongs ; disk of 2 very short rounded lobes, one sixth the length of 

 the 2 conical, oblong ovaries. 



5. MicBADENiA HiKSUTULA, nob. In Brasilia : v. s. in herb, meo (Claussen, sine loco). 



An erect species, apparently of low stature, the specimen being 8 in. high, the basal 

 portion being divided iuto 2 branches, one of which is broken off ; it is clothed with 

 whitish retrose or patent hairs ; the upper axils 1^ in. apart, with warty excrescences ^ 

 line long ; the leaves are subovate, gradually rounded or subcordate at the base, roundish 

 below the summit and constricted into a broadish acute point, rigidly chartaceous, sparsely 

 and rigidly pilose above, with approximate, parallel, fine, immersed nerves, subferrugi- 

 nously opake below, sparsely pubescent, hirsutulous on the prominent midrib, l|-lf in. 

 long, 7-10 lines broad, on pubescent broad petioles l|-2 lines long ; the terminal raceme 

 has a straight, stoutish, pubescent peduncle 2^ in. long, bearing 3-4 distant, alternate 

 flowers, on pilose pedicels 6 lines long, supported by an acute bract 2 lines long ; sepals
