[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.
[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.
[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.
[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.).
