Has. Honduras. Introduced in.1844 by Mrs. Col. Macdonald. 
Oss. This is apparently an undescribed species, closely allied 
to P. squamulosum, Kaulf,, but differing in the larger size, obscure 
venation, and absence of scales on the mid-rib.  T have not seen 
the sori and possess no native specimen in my herbarium.

Has. Mexico. Received in 1843 from Mr. D. Cameron. 
Oss. Although under cultivation these three preceding species 
maintain pretty distinct appearances, yet I have doubts whether 
they, and Polypodium areolatum, Willd., should not be considered 
rather varieties of P. avreum, differing chiefly in the fronds being 
more or less glaucous: a character depending greatly on, the 
place of growth. biter
