Nearest Pt. mnronnta DC. which iL much resembles in leaves and invo- 

 lucral leaves. Ihough Ihe involucres Ihemselves are much raore markedly 

 lurbinale. The heads of Pt. Dinteri have but 5 floscules. those of 

 Pt. mucronata 12—15, and the corollas and achenes of the two are 

 markedly différent.

A well-marked species known from ils perennial congeners hy its 

 very slender habil. its narrowly linear leaves both of slem and of invo- 

 lucre, the very narrow receptacular paleae and Ihe ray-florels wilh a 

 setose (inner) as well as a paleaceons (ouler) pappus. This last characler 

 il shares wilh A. strigosus Less. from which, however. it is distinct in 

 several parliculars.
