There may be more than one species included here, but in the dried state I am 
quite unable to distinguish any of the above from S. viminale; if differences exist, 
they require to be made out and noted from the living plants. To S. viminale I 
am also inclined to refer S. Daltoni, Decne. in Hook. Niger Fl. 149, t. 14, from the 
Cape Verd Islands. This only appears to differ from S. viminale in its much 
stouter stems, which are 2-3 lin. thick in the dried state. ‘To S. Daltoni the 
following references and synonymy belong.—Schmidt, Fl, Cap. Verd. Ins, 214; 
Krause in Engl. Jahrb, xiv. 412; Henriques in Bolet. Soc. Brot. xiii. 144. S.

2 S. andongense, Hiern in Cat. Afr. Pl. Welw. i. 689. Stems 
2-3 lin. thick. Inflorescence as in S. viminale. Corolla larger, pale 
greenish-yellow, sulphur-coloured or whitish; lobes 3-34 lin. long, 
oblong, obtuse, with strongly reflexed margins. Corona like that of 
S. viminale in structure, white. Follicles 3-34 in. long, 3-34 lin. thick, 
terete, acuminate. Seeds (immature) elongate-ovate, with a broad 
margin, glabrous on both sides.—S. Welwitschit, Hiern in Cat. Afr. Pl. 
Welw. i. 689.

Lopollo, Welwitsch, 4261! 
This may be only a variety of S. viminale, but the stems are usually stouter, the 
flowers are much larger and tle seeds glabrous.

Calyx 5-partite. Corolla-tube campanulate or cylindric; lobes 5, 
widely spreading, overlapping to the left in bud. Corona double; 
outer corona at the base of the staminal-column, membranous, annular, 
shortly 5-lobed ; lobes subquadrate or oblong, obtuse, truncate, or 
denticulate ; inner corona of 5 erect fleshy lobes adnate to the staminal- 
column up to the anthers, free above and produced into subulate horns 
‘incurved over the staminal-column, at the base produced into spread- 
ing or deflexed spurs. Staminal-column arising at the mouth of the 
corolla-tube, entirely exserted ; anthers erect, terminated by a mem- 
branous appendage, inflexed over the apex of the style. Pollen-masses
