ADOXA MosciiATELiNA L. Said by Torrey

 acute. Phoranthe fiat chaffy. Rays 5 fertile, 

 equal small and opposed to sepals, ligules short 

 trilobe white, ovary and seed shut between the 

 sepals and internal palea or chaff, similar to se-

1. PARviFLORA Raf. Stem slender branched 

 diffuse smooth, leaves petiolate ovate acute an-

 spontaneous for several years in the orchard

 the South. Annual, Estival, pedal. Leaves

 genus, nearest Achillea, but habit calix and seed 

 unlike. Named after its adventitious produc- 

 tion near Philadelphia. Probably a Florida 

 plant. Seen alive.
