Cassini, in his description of this plant (l. c. p. 91), says 
that the pappus is formed of three squamules, between which 
there exist some rudiments of smaller imperfect squamellules. 
€ fact is that the pappus is biserial, the exterior composed 
of two or three ariste continuous with the nerves of the 
angles of the achenium, the interior shorter, of many ariste 
fringing the margin of the disk (pulvillus, Cass.), which 
Surrounds the base of the corolla and nectarium. This 
latter organ is slightly elongated in the form of a beak, more 
50 indeed in this species, than in any other of the genus.
