ACHYRANTHES, Our Sp. of this Genus 

 appear to form a peculiar Genus indicated by 

 Elliot, see Steiremis. The genera akin Gom- 

 phrena^ lllecebrum, Celosia are yet in great 

 confusion like this; see Adoketon, PfiylejU' 

 dum, Xerandra of mine, and Philoxerus, 



The A, repens of Elliot was a Gomphrena 

 of Linneus.

 ovate, and truncate without teeth : leaves oppo- 

 site, flowers peduncled, autumnal, yellow rays, 

 disk blackish.

 ments, rays 5 to 12 tridentate, seeds compres- 

 sed, sub4gone, chaff* obovate. Creeping plants 

 annual ?
