1. DUPATYA FLAVIDULA (Mx.). 
Eriocaulon flavidulum, Mx. F\. ii. 166 (1803). 
Pepalanthus flavidulus, Kunth, Enum. iii. 532 (1841). 
Dupatya flavidula, Kuntze, Rev. Gen. Pl. 745 (1891). 
Leaves 1 to 2 inches long, three to five-nerved, linear-subu- 
late, floccose at base and smooth or sparingly pubescent above. 
Scapes numerous, five-sulcate, pubescent, 4 to 12 inches high. 
Sheaths longer than the leaves, obliquely fissured, slightly inflated 
at the summit, pubescent like the scape. Heads 2 to 3 lines in 
diameter. Involucral scales straw colored, scarious, smooth, shin- 
ing, oval or ovate, obtuse, somewhat hairy at base, Receptacle 
pilose. Bracts very thin, white, linear, rounded or pointed at 
the apex, about as long as the flowers, slightly hairy, often obsolete. 
Flowers about 1% line high, trimerous, long pedicellate. Sterile | 
flowers—outer perianth segments woolly at base, obovate or trun- 
cate and pilose at the apex. This encloses the inner part of the 
perianth consisting of a smooth, delicate, white; campanulate, 
somewhat three-toothed tube; stamens three, slightly exserted. 
Fertile flowers—outer perianth segments distinct, hairy at base, 
linear, acute, smooth, white, upper similar but much narrower, 
enclosing the ovary and connate over it nearly to the top. Style 
three-parted, forming three stigmas. Seeds sparingly and ob- 
scurely costate when mature. Roots spongy, scarcely nodose, 
Kornicke (Linnza, 27, 590) under the name /riocaulon flavi- 
dulum, Mx., following Pursh (Fl. 1, 92) and Elliott (Bot. ii 566) 
states that two plants have been sent from North America under 
this name and that he regards Kunth’s P. flavidulus as some- 
thing distinct from the plant of Michaux. That which he de- 
scribes is undoubtedly something distinct and is clearly an 
Eriocaulon, but, so far as I can judge, it corresponds very nearly, 
if not quite, to &. articulatum. The plant of Elliott is also, I 
think, that species. Michaux distinctly calls his species puberu- 
Jent and the scapes aggregated and five-striate, while his other 
characters correspond very well with our plant. There is not, 
so far as ascertained, any other in the habitat given by him, 
“ Carolina” that bears such characters. 
Low sandy pine barrens, So, Va. to Florida. March—July.
