11/3. S. foetida (Cav.) Blake var. decipiens Blake, n. var., 

 pappo nuUo, achenio glabro. As the typical form, but achene gla- 

 brous and pappusless; leaves mostly entire, but at least the upper 

 auriculate-petioled.— It is barely possible that the specimen is a 

 hybrid with S. exaristata, with which species it was identified by Dr. 

 Gray; but the heads and leaf -bases are quite those of S. foetida. 



Specimen examined: Chihuahua: southwestern part, Aug.-Nov. 

 1885, Palmer 440 part (type in Gray Herb.). 



41 " Vulg. Mirasol amarillo ou Lampotillo" (i. e. j^ellow turnsol or little fire).
