 This most variable plant is a native of the coast region of the south- 

 eastern btates from Maryland, W. M. Canity, to Florida, Alabama, and, 

 according to RiddelFs Cat., to Louisiana.— Numerous varieties, often 

 difficult to class, have been described in European gardens. 



Linmeus' diagnosis: foliis lanceolatis acuminalis together with the 

 Hab. Virginia, points to the narrow-leaved form of 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 have been obtained 

 from Dr. Mellichamp, of South Carolina, on which the following descrip- 

 tions are based. 



The genuine plant has a short trunk of 2-5 inches or a foot, (Chapm. 

 Fl. 475), stiffer, rougher, " reed-like," dull green leaves and smaller cap- 

 sules than any other variety, and blooms earlier, in S. Carolina in May, 

 in gardens of St. Louis in the first weeks of June.— The narrow-leaved 

 form makes tufts of 60-S0 or 100 leaves, 16 or 18-20 and 22 inches long, i-i\ 

 rarely ih inches wide, widest about the middle, tapering to a hard ob- 

 tusish 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, 

 very soft and smooth, pale green, below with oblique, spatulate bracts, 2, 

 rarely 3 inches long; panicle with numerous nearly horizontal dense-
