Captain Stansbory states that the flowers are purple. MALACOTHRIX SONCHOIDBS, Torr. and Gray, Fl. 2, p. 486.- Shore of the Salt Lake, and on Carrington's Island, May 30. The pappus is decidedly double in this species. The outer series consists of five slender, nearly glabrous, and somewhat persistent bristles; the inner 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 Plantm Fendleri-ance, ( p. 113, No. 453,) says that he noticed in « M. $ onchoide* y M. coulteri, and especially in M. californica, that two ( opposite) bristles of the pappus are naked, instead of barbellate, and rather stronger and less deciduous than the others." In M. sonchoides I believe the outer series always consists of five bristles; but in some species they are variable in number, and in others are entirely wanting. CRBPIS ACUMINATA, Nutt. 1. c; Torr. and Gray, Fl. 2,. 489.- Stansbury's Island, Salt Lake, June 23. This is the tallest of our indigenous species of crepis. Some of our specimens are about three feet high. The radical leaves ( including the petioles) are more than a foot in length. Plate VIII. Crepis acuminata, of the natural size.
