An illustrated flora of the northern United States, Canada and the British possessions, from Newfoundland to the parallel of the southern boundary of Virginia, and from the Atlantic Ocean westward to the 102d meridian. Botany; Botany. 2. Dichromena latifolia Baldw. Broad- leaved Dichromena. Fig. 840. Dichromena latifolia Baldw.; Ell. Bot. S. C. & Ga. 1: 90. 1816. Culm stout, obtusely triangular or nearly terete, the leaves lanceolate or linear-lanceo- late, tapering gradually to a long-acuminate apex from a broad base, i4"-4" wide, some- times overtopping the culm, but the lowest much shorter, those of the involucre 7-10, strongly reflexed when old. Head globose, 6"-9" in diameter; spikelets oblong, subacute; scales ovate-lanceolate, nearly white, rather obtuse; achene nearly orbicular in outline, pale brown, faintly wrinkled transversely and lon- gitudinally, so as to appear reticulated; tu- bercle decurrent on the margins of the achene. In wet pine barrens, Virginia to Florida and Texas. June-Aug. 13. RYNCHOSPORA Vahl, Enum. 2: 229. 1806. Leafy sedges, mostly perennial by rootstocks, with erect 3-angled or terete culms, nar- row flat or involute leaves, and ovoid oblong or fusiform, variously clustered spikelets. Scales thin, l-nerved, imbricated all around, usually mucronate by the excurrent midvein, the lower empty. Upper flowers imperfect, the lower perfect. Perianth of 1-20 (mostly 6) upwardly or downwardly barbed or scabrous bristles, wanting in some species (no. 2). Sta- mens commonly 3. Style 2-cleft, 2-toothed or rarely entire. Achene lenticular or swollen, not 3-angled, smooth or transversely wrinkled, capped by the persistent base of the style (tubercle), or in some species by the whole style. [Greek, referring to the beak-like tubercle.] About 200 species, widely distributed, most abundant in warm regions. Besides the following, some 35 occur in the southern United States.
