most variable plant is a native of the coast region of the cham Sead from Maryland, W. M. Canby, 
to Florida, Alabama, and, maces to Riddell’s Cat., to Louisiana. — Numerous varieties, often difficult to class, have 
been ‘verter European garden

form an what I have described as the genuine plant, as the one he and Gronovius had in view. Of this and other 
forms numerous specimens and full notes hive been obtained from Dr. Mellichamp, of South Carolina, on which the 
following descriptions are based. 
4 nuine plant has a short trunk of 2-5 inches or a foot (Chapm. Fl. 475), stiffer, rougher, “ reed-like,” 
dull green leaves and smaller no than any other variety, and blooms earlier, in S. Prin in May, in gardens 
of St. Louis in the first weeks of June. — The narrowsleaved form makes tufts of 60-80 or 100 leaves, 16 or 18-20 and 
22 inches long, 1-1} rarely 14 fees anne widest about the middle, tapering to a hard sollte point, with numerous 
rather thin curly fibres. The broad-leaved variety has only 30-60 leaves, 20-24 inches long, 2-3 inches wide about 
the upper third, and broad to the almost obtuse blunt tip; outer shorter leaves often broad-spatulate and quite obtuse ; 
margin with fewer, coarser, more curly threads. The scape of both forms is 4-8 or 9 feet high, stout, eth soft an 
smooth, pale green, below with oblique, spatulate bracts, 2, rarely 3 inches long; panicle with numerous nearly 
horizontal dense-flowered branches as long or longer than the naked part of the scape. Flow 2 34-3 ish [53] 
wide, white, tinged with green ; stamens as long as the pistil, at last spreading, the patie eventually 
recurved stigmas rather shorter than the ovary. Capsule 13 inches long, more or less constricted, thin, smooth, and 
papery in some localities, hard, wrinkled, and longer beaked in others; secondary dissepiments mostly very eure. 
not reaching to the centre, but in a Maryland ena and in some ‘pallivaied ones, of the ordinary form, so that 
specific character can be based on them ; seeds 6 mm. diam. — Forms intermediate between a. and 6. are found wild 
and in cultivation ; leaves sometimes more loud a fewer fibres, shorter stamens or stigmas, longer capsules, 
larger seeds, 
The variety flaccida is described from plants in common cultivation about St. Louis; wild specimens I have not 
seen. It is donhtfal whether it is Haworth’s plant, which has fila validissima, or of the Refugium, with broad, involute 
leaves, but the short attenuated stigmas fully agree; the characters indicated in Gard. Chron. 1. c., “an irregular,
