sparsè pilosa, apice truncata, in disco magno dilatata, pappo

Has. In the dried up sandy beds of streams near Icó, Province of

Descr. Herba annua, dichotomo-ramosa, subpedalis. Rami 
teretes, striati, villoso-hirsuti, foliosi. Folia alterna, sessilia, basi 
amplexicaulia, obtusa, bipinnatifido-lobata, lobis latis obtusis 
mucronatis utrinque hirsutis, sesquipollicaria, 8-10 lin. lata.

The plant on which I establish this genus has quite the habit of 
Grangea, and agrees with it, besides, in several points of structure; 
but the single series of ligulate florets prevents it from being asso- 
ciated with the Baccharideæ, and removes it to the subtribe 
Asterinee. ts characters otherwise resemble the Be//idez, and 
its situation seems to be between Myriactis and Garuleum. The — 
plant in all its parts has a powerful smell of Chamomile, and it w 
used as a substitute for it by the inhabitants of the districts in 
which it grows.
