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 -4. dichotoma of Mx. quite distinct 

 by broad leaves elliptic, stem filiform smooth, 

 flowers as in 837. 



338, Anychia 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 

 ad pressed 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, tsessiliflora N. 

 but his jP. 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 ciUolate, stipules 

 lanceolate acuminate, flowers solitary. — Des- 

 cribed from a specimen from Florida anony-
