FOOTNOTES:
[Footnote 1: Notes were also drawn at a later date from “The Useful
Plants of Nigeria,” J. H. Holland. Kew Bulletin, Additional Series.]
[Footnote 2: Macmillan & Co., St. Martin’s St., London, W.C.2 (1926),
20s. net.]
[Footnote 3: The names used for these three groups are applied here for
the convenience of the student. The “Parietales” in this sense are not
the _Parietales_ of either Bentham & Hooker or of Engler.]
[Footnote 4: The flowers of this family (which consist of 5 usually free
sepals, a 5-lobed corolla, 5 stamens and a pistil of 2 carpels) are
peculiar (i) by the _coronal_ lobes, either free or connate, simple or
double at or inside the mouth of the tube of the corolla; (ii) by the
stamens which, although exceptionally free at the base, are usually
connate by the filaments; these, with the anthers and their appendages
forming the _staminal column_, but the anthers being free or united to
the dilated part of the style; the anthers are 2, dehiscing by terminal
or lateral slits and are continued on the margins or below the pollen
cells by wing-like processes (_anther-wings_); the connectives of the
anthers are often produced into membranous (rarely fleshy or inflated)
terminal, sometimes connate appendages, or apiculate, or unappendaged;
(iii) by the pollen which is either granular or more commonly united
into 1 or 2 clavate, waxy masses or _pollinia_; (iv) by the pistil
which, although consisting of 2 carpels, is united above into a dilated
pentagonal disk; (v) by the fruit consisting of 2 follicles or by
abortion one only, the seeds being usually numerous, imbricate, somewhat
like fish scales, generally crowned with a tuft of long silky hairs.]
[Footnote 5: Herbs; stems cylindrical or trigonous, solid. Leaves grass-
like, tough, but sheaths (except in _Eriospora Schweinfurthiana_) not
slit down one side. Infl. umbellate, capitate or panicled, made up of
spikes bearing spikelets composed of an axis (_rhachilla_) and of empty
or flower-bearing bracts (_glumes_). Fl. minute, 1 or 2-sexual, in axils
of glumes. Per. 0, or consisting of 2-6 hypogynous scales or bristles;
sta. 1-3, anthers basifixed; style 2-3 branched, or subentire, base
often thickened; fruit a compressed or 3-gonous nut.]
[Footnote 6: Differs from _Cyperus_ by never being leafless, by
disarticulation of (always winged) rhachilla in one piece above the two
lowest empty glumes, and by the spikelets which, in Cyperus never less
than 5 fld., may here be as little as 1 fld. (although at times up to 20
fld.).]
