Subsect. Noveboracenses.

 tegerrima vel margine scepe serrulata. Inflorescentia cynioso- 

 -paniculata, plana vel concavo-depressa, amhitu oh py ramidata,

 Involucrum late campanidatum. Beceptacidum planum, nudum. 

 Pappi setce interiores persistentes, numero 40 — 70, tenues, fili- 

 formes, scepe purpurascentes, exterioribus subindistinctis, ince- 

 quilongis, anguste linearihus vidgo 8-plo longiores. Corollce satis 

 longce, 8 — 10 mm in speciebus examinatis, glahrce, tubo - 3 long, 

 corollce. Antherce idtra 3 mm longce, ligida ^'5 — ^ g long, antherce,

This subsection includes several Mexican species, and all 

 North American ones. It matches Gleason's Panicidatce veroe, 

 except his Alamaniance. It differs from the PolyantJies chiefly 

 in its flat or depressed inflorescence, larger corollas and anthers, 

 and nearly glabrous achenes. 



Only one West Indian species belongs here. viz. F. insii- 

 laris Gleason, described as from the Bahama Islands. Evi- 

 dently the origin of this species can be traced back to Florida, 

 where related species are common.
