26. S. Eminii, Lngl. Pfl. Ost-Afr. C. 314. Stems tall, erect, 
much branched ; branches ascending. Leaves narrowly oblong or lance- 
olate, obtuse; lower shortly petioled; upper 5-7 lin. long, 1-2 lin. 
broad, narrowed into a very short petiole. Inflorescence cymose- 
corymbose ; flowers very small, 4-5 umbellate at the ends of the 
branches, 5-merous; pedicels about 4 lin. long. Calyx-segments very 
unequal, 14-24 lin. long, $-3 lin. broad, linear-oblong, obtuse, with 
recurved-spreading tips. Corolla-lobes 14-2 lin. long, 1—1} lin. broad, 
oblong, obtuse, with a pair of minute ciliate nectaries near the base. 
Stamens 1-1} lin. long. Ovary distinctly narrowed into a stout style 
about { lin. long; stigmatic lobes longer than broad, ovate, obtuse. 
Nile Land. Uganda: on the Lendu Plateau, west of the Albert Nyanza, 
Stuhlmann, 2708, 2758! 
Perhaps to this species should also be referred the following Uganda specimens :— 
Ruwenzori, Scott-Elliot, 7569! and second day’s march from Nandi, Whyte! But 
they differ from the small branch of the type which I have seen, in being more 
floriferous with the sepals but slightly or not at all recurved at the tips, corolla-lobes 
24 lin, long, and the stigma more sessile. Both are very much branched and very leafy 
specimens 10-14 in, high, with exceedingly numerous rather crowded small cymes ; 
the flowers are frequently 4-merous— NW. E. Br. 
27. S. curtioides, Gily in Engl. Jahrb. xxx. 379, A glabrous 
annual, 24-5 in. high ; stems slender, simple, or with about 1 branch.
