than the whitish pappus. — Black Hills, S. Dakota; Dr. W. H. For- 

 wood, June, 1887. Allied to H. Fendleri. 



ERiOGONUii (Eriantua) Alleni, Watson in Graj's Manual, 

 6 ed., p. 734. Perennial, white-tomentose ; stems naked below the 

 dichotoraous branches, 1|- to 2 feet high: radical leaves long-petiolate, 

 ovate-lanceolate, cuneate to subcordate at base, the blade 4 inches 

 long, greener above ; upper leaves in whorls of 4 or 5 at the nodes, 

 short-petiolate, ovate to oblong or oblong-ovate, acute, the lower 1^ 

 to 3 inches long, much reduced above : involucres tomentose, those 

 in the forks short-pedunculate ; flowers glabrous, on tomentose pedi- 

 cels, yellow, the segments elliptical, very obtuse, scarcely over a line 

 long. — Collected on rocks, about a mile from the White Sulphur 

 Springs, W. Virginia, by Dr. T. F. Allen in 1874. Closely allied 

 to the more southern E. tomentosuin^ which differs in its more leafy 

 stem, the lower leaves oblanceolate and long-attenuate at base, the 

 upper sessile, and in the larger tomentose white flowers with broadly 

 lanceolate segments. 



Spiranthes precox, Watson, 1. c. 503. {^S. graminea, Lindl. (.''), 

 Gray, Manual, 4 ed., p. xcviii. S. gram{7iea,\a.v. Walteri, Gray, 1. c, 

 5 ed., p. 505.) A comparison of specimens of true S. graminea (col- 

 lected by Dr. E. Palmer in Jalisco, Mexico) with the plant of the 

 Atlantic and Gulf coasts that has been referred to it, shows too 

 important differences to permit the latter to be considered merely a 

 variety. The more leafy stems of our plant, its broader and more 

 hyaline and usually more acuminate bracts, its larger flowers, its 

 narrower and much less recurved li}), the more acutely beaked rostel- 

 lum, and the narrower capsule, should suffice to characterize it as a 

 distinct species. 



Iris Caroliniana, Watson, 1. c. 514. Rootstock rather stout: 

 leaves elongated, 3 feet long by 12 to 15 lines broad, thin and lax, 

 bright green, not glaucous or scarcely at all so : stem slender, 2 feet 

 high ; peduncles 2-flowered ; bracts scarious, exceeding the pedicels : 

 ovary 8 lines long, bearing a cylindric-campanulate tube 6 lines long ; 

 petals distinct at base, the outer 3 inches long, broadly spreading, 

 with a yellowish green claw veined with brown, the elliptical blade 

 lilac veined with purple and with a yellow spot reaching to the cen- 

 tre ; inner petals oblong-spatulate, 2^ inches long, the blade lilac and 

 claw yellowish : anthers as long as the filaments : wing of the stigma 

 continuous with the erosely toothed lilac crest : capsule nearly 2 

 inches long, oblong, somewhat triangular with very rounded angles : 

 seeds in one row in each cell, very large (4 or 5 lines broad and 2
