point at the apex, whilst in S. angustissimum and S. Whytei the keels are 
produced into the point or points, the body itself being obtuse behind the base of 
the point. 
3. S. angustissimum, X. Schum. in Engl. Jahrb. xvii. 123. 
Stems 3-4 ft. high, branched above, puberulous. Leaves sessile, 
{-2} in. long, 3-1 lin. broad, linear, with strongly revolute margins, 
puberulous. Umbels numerous, sessile, lateral at the nodes, 
6-10-flowered ; pedicels 14 lin. long, slender, puberulous. Sepals 1 lin. 
long, lanceolate, acuminate, puberulous. Corolla rotate, lobed nearly to 
the base; lobes 14-13 lin. long, } to scarcely 3 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 4 lin. 
above the base of the staminal-column and twice as long as it, 3-1 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 trifid. 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. angustissimum ; 
the horn on the coronal-lobes is usually subulate, bat occasionally it is bifid or even 
‘trifid at the apex, a variation which also occurs in other species. 
4. S. Whytei, V. £. Br. Stems apparently 3-4 ft. high, puberulous, 
branching. Leaves 14-3 in. long, 3-1 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 14-13 lin. long, pubescent. Sepals 1-1} lin. long, 
4-4 lin. broad, lanceolate, acute, pubescent. Corolla 4~44 lin. in diam., 
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. 
Coronal-lobes arising } lin. above the base of the staminal-column and
