OF NORTH AMERICA. 43 



segments hardly acute, not nervose, A var. 

 my A. conferta atl. j. has the same habit, but 

 flowers crowded, leaves subserrulate. I have 

 several other var. of this Genus, my A. poly go- 

 noides is the 2d (A. canadensis or Nuttal and 

 most of our botanists,) it is quite erect with nar- 

 row longer leaves often uncial patent subciliate, 

 flowers nervose acute. The A. capillaris N. 

 is the real A. dlchotoma of Mx. quite distinct 

 by broad leaves elliptic, stem filiform smooth, 

 flowers as in 837. 



338. Anyciiia nudiflora R. smooth, erect, 

 branches unilateral, leaves linear acute ; flow- 

 ers in terminal naked cymes with few leaves, 

 pedunculated, caliculated by radiate oval stipu- 

 les, calix nervose hardly acute — from Fiorida 

 collected by Kin, a small plant forming a pas- 

 sage to Argyrocoma, but flowers as in Anychia 

 and leaves small. 



839. Argyrocoma imbricata Raf. Parony- 

 chia argyrocoma N. Anychia do Mx. has crow- 

 ded leaves and flowers narrow linear elongate 

 adpressed imbricate, flowers with imbricate 

 silvery bracts or stipules. — While the A. dicho- 

 toma which is Achyranthes do Linn, lllece- 

 brum do Wild ^c, has flowers corymbose with 

 lax and less silvery bracts ; both have the calix 

 long with very thick dorsal nerves, end very 

 acuminate. A third sp. is Par. sessiliflora N. 

 but his p. herniarioides is probably of next 

 Genus. 



810. Plagidia rufa Raf. Anychia hernia- 

 roides Mx ? dichotome scabrous, much branch- 

 ed fastigiate entirely rufous, leaves obliqual 

 crowded elliptic mucronate ciholate, stipules 

 lanceolate acuminate, flowers solitary. — Des- 

 cribed from a specimen from Florida anony-
