Notes
A pair of follicles collected by G. Mann in Fernando Po in 1860 (about the same time as the flowering specimen No. 177, quoted above) belongs very probably to S. Preussii. The follicles are hornshaped with rather obtuse ends, 10 in. long, 1 1/2 in. in. diam., reddish-brown and smooth. The seeds are oblong-lanceolate, obtuse at the base, long acuminate, brown, downy, 5–6 lin. long; the naked foot of the awn measures 1 2/3–2 in., the plume 3/4– 1/4 in. The follicles collected by Mann in Fernando Po in 1860 referred to by me in a to S. Preussii do not belong to this species, as Gilg who had an opportunity of examining seeds of this species has pointed out. A description of the follicles and seeds will be found under S. bracteatus, Franch., which Gilg, after an examination of an authentic specimen, declares to be identical with S. Preussii .
