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 , Phylepi- 
dum , Xerandra of mine, and Philoxerus . 
The A . repens of Elliot was a Gomphrena 
of Linneus.
