The pappus is decidedly double in this species. The outer series consists of five slender, nearly glabrous, and somewhat persistent bristles; the in^ er of about fifteen scabrous capillary bristles, which are caducous, and separate in a ring. I have seen the same character in two or three other species. Dr. Gray,, in his Plantoe Fendleri-anae, ( p. 113, No. 458,) says that he noticed in " M. eonchoitjes, itf. oouUeriy and especially in M. californida, that two ( opposite) bristles of the pappus are naked, instead of barbellate, and rather stronger and less deciduous than the others." . In M> sonchoides 1 believe the outer series alwayB consists of five bristly; l> ut in some specieb they are variable in number, and in others are entirely wanting. - CREPIS ACUMINATA, Nutt. 1. c.; Torr. and Gray, Fl. 2, 489.- Stansbury's Island, Salt Lake, June 28.
