upwards, all filiform, tortuous and intermingled over the top of the 

 stamens and style ; the entire lobe 1^-1 J lin. long, the undivided part 

 rather more than h lin. long. Stamens about h lin. long; filaments 

 very short, about \ as long as the glabrous anthers, the lobules ajter- 

 nating with them very rudimentary and not forming a very evident 

 ring. — Pleurostelma africanum, Schlechter in Journ. Bot. 1895, 303, t.

XHozamb. I>lst. Britisli East Africa : without precise locality, but, according 

 to the number, was probably collected between Maungu Mountain and Mbuyuui, in 

 Tiiita district, growing in red sand, Scott-Elliot, 6175 ! 



I can find no character to separate this plant from Tacazzea ; the coronal-lobes 

 may be conii)ared with those of T. venom, var. Martini, N. E. Br. except that they 

 :ire trifid instead of bitid. They are inaccurately described and figured in the 

 Journal of Botany. 



2. T. volubiliSy N. E. Br. Stem climbing, stout, woody, more 

 or less branching, greyish-brown, with small scattered tubercles, 

 glabrous. Leaves and flowers fascicled on very short (2-G lin. long) 

 stout lateral branches. Leaves very shortly petiolate, ^-1 in. long, 

 2-3|- lin. broad, lanceolate- oblong, obtuse or subacute, cuneately 

 narrowed towards the base, subtomentose or velvety-pubescent on both 

 sides. Cymes subterminal on the short lateral branchlets, umbel-like, 

 3-4-flowered, subsessile or wqth peduncles, J-^i ^^°- ^^^o 5 pedicels 

 1-1^ lin. long, tomentose. Sepals |-1 lin. long, |-J lin. broad, ovate, 

 subacute, tomentose. Corolla 5-lobed nearly to the base, rotate, 5| lin. 

 in. diam., quite glabrous; lobes 2J lin. long, IJ lin. broad, oblong, 

 obtuse, with a thick fleshy subquadrate sulcate tubercle at their base. 

 Coronal-lobes inserted at the base of the stamens at the sinuses of the 

 corolla, and connected in a ring at the base with the tubercles on the 

 corolla-lobes, 2 lin. long, simple, filiform, spreading in the basal part, 

 then inarched in a bold curve over the stamens, tortuous at the apex. 

 Filaments of the stamens J lin. long, glabrous, anthers h lin. long, 

 oblong, apiculate, glabrous, connivent or slightly cohering at their tips 

 over the very short conical apex of the st^le. Raj^hionacme voluhilisy

This plant in no way resembles a Raphionacme, its structure and habit is entirely 

 that of Tacazzea. 



3. T. pedicellata, K. Schum. in Engl. Jahrh. xvii. 115. Stem 

 somewhat quadrangular in the younger parts (in the dried state), 

 slightly scabrous, dark red-brown. Leaves with sparsely puberulous 

 petioles 3-5 lin. long; blade 2-4J in. long, i-lj in. broad, oblong- 

 lanceolate, acute or shortly acuminate, rounded at the base, quite 

 glabrous on both sides ; veins numerous, horizontal, straight and 

 parallel, intramarginal vein about J line distant from the margin.
