According to description this only differs from S. pumila, Hochst., in its more 
numerous and filiform stems, which in S. pumila are } lin. thick. 
12. S. crassiuscula, Gilg in Engl. Jahrb. xxvi. 107. A perennial 
herb, 2—5 in. high; stems many, glabrous, erect or decumbent at the 
base, root-leaves and lower stem-leaves with a_ thick elliptic-oblong: 
obovate blade 4-3 in. long, 24-4 lin. broad, narrowed gradually into a 
petiole 4—1 in. long; upper Jeaves smaller, spathulate or obovate-cuneate.. 
Cymes 1-3-flowered, corymbose ; flowers 5-merous. Calyx } in. long; 
lobes obovate or obovate-oblong, obtuse. Corolla pale blue (Johnston), 
yellowish in the dried state; lobes 4-5 lin. long, oblong, with a pair of 
ciliate nectaries near the base. Stamens much shorter than the corolla- 
lobes. Ovary elliptic-lanceolate, slightly narrowed to the very obtuse 
sessile 2-lobed stigma.—S. pumila, Engl. Hochgebirgsfl. Trop. Afr. 398,.

Sir Harry Johnston states that the flowers are pale blue, but in the dried state 
they are yellowish, with some of those that are faded dull lilac. 
13. S. Volkensii, Gilg in Engl. Jahrb. xxvi. 108. A dwarf 
glabrous perennial, 2-4 in. high, with a thick many-headed rootstock. 
Radical leaves crowded or rosulate, 3-1} in. long, 14-5 lin. broad, 
ascending, lanceolate, obtusely pointed, tapering into a long petiole 
below ; stem-leaves in about 2-3 distant pairs, 5-8 lin. long, 1—2} lin. 
broad, sessile, narrowly lanceolate or ovate-lanceolate, obtuse (very 
acute, ex Gilg), all apparently somewhat fleshy or subcoriaceous, not 
membranous as originally described. Flowers about 3 in a terminal 
cyme, 5-merous; pedicels 14-6 lin. long. Sepals 2—5 lin. long, #1 lin. 
broad, lanceolate, acute, about as long as the corolla. Corolla-lobes 
rather thick, 34-54 lin. long, 14-2 lin. broad, lanceolate, acute, or rarely 
oblong, obtuse, without nectaries (with 2 nectaries, ex Gilg) at the 
base. Stamens 2-2} lin. long; anthers apiculate, somewhat acutely 
sagittate at the base. Capsule 34-4 lin. long, about 1} lin. broad, 
elongate-ovate, acute ; valves tipped with the very short (about 4 lin. 
long) style ; stigma small, about } lin. broad, very obtuse. 
Mozamb. Dist. German East Africa: Kilimanjaro, on the lava-field of the- 
western slope of Mawenzi Peak, 14400 ft, Volkens, 1357! 
A remarkable species, very like S. crassiuscula, Gilg, in appearance, but with 
acute sepals, and much thicker petals than in any other species. In a port‘on of the: 
type specimen, kindly lent by Professor Engler, I could find no trace of the fringed 
nectaries which are described by Gilg as present near the base of the petals, so they 
may perhaps be present or absent in this species. N.E. Br.
