KErOKT ON THE BOTANY OF JUAN FERNANDEZ AND MASAFUERA. 39 



places, so that the specific distinctness of this and Gnaphalium/ernandezianum, from all 

 previously described forms, is problematical, and only to be ascertained by studying the 

 whole of the species of this group of the genus. 



Gnaphalium fernandezianum, Pbilippi. 



GnapTudium fernandezianum, Philippi in Bot. Zeit, 1856, p. 646. 



Juan Fernandez and Masafuera. Philippi. 



Specimens collected in Juan Fernandez by Peed and Moseley agree fairly well with the 

 description; but they are named, perhaps correctly, Gnaphalivm berterianum, DC, a 

 common Chilian species. 



[Ghiaphalium decurrens, Ives, is recorded (Gay, Fl. Chil., iv. p. 224) from Juan Fer- 

 nandez, probably through an error in naming. It is a North American species, not unlike, 

 though distinct from, Gna/phalium ckeiranthifolium^] 



Galinsoga parviflora, Cav. 



Galinsoga parviflora, Cav., Ic. PL, iii. p. 41, t. 281; DC, Prodr., v. p. 667; Gay, Fl. Chil., iv. 

 p. 267. 



Juan Fernandez. Philippi. 



An annual plant generally diffused in cultivated ground, roadsides, &c, in North and 

 South America, as well as in many parts of the Old World, where, however, it is known to 

 have been originally introduced. It is doubtless a colonist in Juan Fernandez.

As the name Balbisia is retained for a genus of Geraiiiaceae, it is only right to restore 

 Meissner's appropriate name 1 Rhetinodendron for this genus.for there is no doubt that he had 

 the same plant under consideration which De Candolle described and named Balbisia berterii. 

 Meissner founded his genus without giving any specific name or citing the collector of the 

 plant he described. By an oversight Rhetinodendron was not taken up in the Genera 

 Plantarum of Bentham and Hooker, though Steudel and Pfeiffer both include it as a 

 synonym of Balbisia, DC. Baillon, perceiving that the name Balbisia was already 

 occupied, replaced it by Vendredia, overlooking the fact of the existence of Rhetino-
