3. S. ForTIpA (Cav.) Blake var. decipiens Blake, n. var., 
pappo nullo, 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: CatavanHua: southwestern part, Aug.—Nov. 
1885, Palmer 440 part (type in Gray Herb.). : 
41“Vulg. Mirasol amarillo ou Lampotillo” (i. e. yellow turnsol or little fire).
