point at the apex, whilst in S. angvstissimum and S. Whyiei the keels are 

 produced into the point or points, the hody itself being obtuse behind the base of 

 the point. 



3. S. angustissimum, A^ Schum. in Engl. Jahrh. xvii. 123. 

 Stems 3-4 ft. high, branched above, piiberulous. Leaves sessile, 

 J-2J in. long, J-1 lin. broad, linear, with strongly revolute margins, 

 puberulous. Umbels numerous, sessile, lateral at the nodes, 

 6-l()-fiowered ; pedicels IJ lin. long, slender, puberulous. Sepals 1 lin. 

 long, lanceolate, acuminate, puberulous. Corolla rotate, lobed nearly to 

 the base; lobes IJ-lf lin. long, J to scarcely § lin. broad, oblong- 

 lanceolate or linear-oblong, acute, pubescent on the back, villous within 

 on the apical part and margins with long white woolly hairs and thinly 

 covered on the central part with minute very often obtuse papilla-like 

 hairs, hardly distinguishable by the eye. Coronal-lobes arising \ lin. 

 above the base of the staminal-column and twice as long as it, |-1 lin. 

 long (including the horn) subquadrate, very obtuse and variously crenu- 

 late at the apex, with a linear-subulate horn arising just below the 

 apex on the inner face and 2 keels decurrent from it, sometimes the 

 horn is more or less deeply bifid or trijSd. Staminal-column \ lin. long, 

 not dilated at the base of the anthers ; anther- appendages ovate, obtuse, 

 inflexed over the truncate apex of the style. — K. Schum. in Engl. Pfl.

I can find no character whereby to separate S. elatum from S. angusfissimum ; 

 the horn on the coronal-lobes is usually subulate, but occasionally it is bifid or even 

 trifid at the apex, a variation which also occurs in other species. 



4. S. Whytei, X. E. Br. Stems apparently 3-1 ft. high, puberulous, 

 branching. Leaves l|-3 in. long, J-l lin. broad, linear, abruptly acute, 

 ascending, or erect, very revolute along the margins, nearly glabrous or 

 with a thin and very minute pubescence above, puberulous along ,the 

 midrib beneath. Umbels numerous, sessile, lateral at the nodes, many- 

 flowered ; pedicels IJ-lj lin. long, pubescent. Sepals 1-1 J lin. long, 

 J-Jlin. broad, lanceolate, acute, pubescent. Corolla 4-4 J lin. in diani., 

 purple-brown, pubescent on the back and inner face with fine short 

 white acute hairs and bearded at the tips and along the margins of the 

 lobes with long woolly hairs ; lobes 2-2^ lin. long, nearly 1 lin. broad 

 when flattened out, oblong or oblong-lanceolate, acute, ascending- 

 spreading, replicate throughout their length, incurved at the tips.
