(i/ilaisis, 5 and hence likewise must be synonomized with B. alau- 

 sensis. 



It is interesting to note that Bidcns critkmifolia H. B. K. was 

 suspected by Sprengel (Syst. Veg. ed. i6 m . p. 454. 1826) of be- 

 longing to B. alaiiscnsis. A study of the types of both species 

 shows, however, that they are entirely distinct.

Bidens tenella L., Amoen. Acad. 6:96. 1763. — This species, 

 was included by DeCandolle (Prodr. 5:605. 1836) among the 

 "species non satis notae." A sheet with two specimens exists 

 however, in the Linnaean Herbarium. These are in good condi- 

 tion and show at once that the species is in no way a Bidcns, and 



s B, valparadisiaca was based (Colla, /. c.) upon a specimen from Valparaiso, 

 while B. chilensis, which DeCaxdolle himself equated with it, was based upon a 

 specimen collected in the immediate vicinity, but to the northeast ("circa Quillota," 

 DC, I.e.).
