422 TAMARIX GALLICA. 



Obs. I have some doubts of this being a new species, as 

 it appears to answer well to the description of Polypodium 

 siifolium of Willd., which Blume has placed in Aspidium; 

 and, it is very probable, that Aspidium menisciicarpon, A. 

 sanctum, and A. lineatum of Blume, are only different states 

 of the same plant: one thing to be said against its being 

 either of these is, that no trace of an indusium is to be 

 found even in very young sori.

When describing the Tamarix Canariensis, Willd., for the 

 Phytographia Canariensis, forming part of the Histoire Na- 

 turelle des lies Canaries, which I publish in conjunction with 

 M. Berthelot, I was necessarily obliged to take a cursory 

 view of the whole of this intricate genus, and particularly of 

 its European species. I then came to the conclusion that 

 two of these had been confounded under the name of Tama- 

 rix Gallica, and that the true T. Gallica, Linn., was usually 

 found more abundantly on the western coasts of France, whilst 

 much of the Mediterranean form known under that name 

 was to be referred to T. Canariensis^ Willd. The accompany- 

 ing plate and descriptions sufficiently prove the existence of
