line high. Receptacle hairy as in No. 2. Styles divided into 

 three simple stigmas. 



Kornicke attributes this species to Ebenezer, a place in mid- 

 dle Georgia, collected there in July by Beyrich. Tt was dis- 

 tributed as L. glabrum by Curtiss, No. 3,022, collected by him 

 on " Sandy shores, Walton County, N. W. Florida." September. 



Bentham and Hooker (Gen. PL iii. part 2, p. 1,024) regard 

 Kornicke's plants as well developed specimens of L. anceps, but 

 the species is quite distinct both from L. anccps 2S\(S. L. glabrum. 

 From the former it is distinguished by its much smaller size, 

 numerous scapes, smaller and more elongated heads, obtuse 

 involucral scales, far smaller flowers and simple stigmas ; from the 

 latter b}^ its hairy scapes, grayish-villose, nearly globose and far 

 smaller heads.

L. digynnm, Korn. Linnaea, xxvii. 570, (1854). 



I have not seen specimens of this. Kornicke attributes it to 

 Alabama, from whence it was sent by Bentham, and describes it 

 as having a leafy epigean stem ^^ to i ^ inch in length. 

 Leaves smooth, nervose-striate, flat, bright green, 4 to 7 lines 

 long. Scapes smooth, 3 to 5 inches high. Sheaths obliquely 

 fissured, sparsely pilose, a Httle longer than the leaves. Heads 

 semi-globose, i line in diameter, grayish-villose. Involucral 

 scales oblong, acute, ciliate at the apex and villous on the back, 

 at length glabrescent, fuscous. Bracts spatulate, carinate. Re- 

 ceptacle pilose. Flowers pedicellate ; segments of the perianth 

 connate toward the base, spatulate, rounded and hairy at the 

 apex. Stamens three, anthers oblong, white; the triple seg- 

 ments of the rudimentary pistil in the sterile flower papillose. 

 Fertile flowers sessile, segments of the perianth free, obovate, nar- 

 rowed at the base, pilose at the top of the back. It differs, ac- 

 cording to Kornicke, from all the preceding species in having a 

 two-celled ovary, two appendices, a two-parted style and bifid 

 stigmas. 



It is regarded by Benth. and Hook. 1. c. as probably a 

 depauperate form of L. aticeps, with heads not yet well devel- 

 oped, but it appears to me to come much nearer to L. Bcyrichia- 

 num. Fresh specimens are very desirable.
