ing, rather stout, chaffy : stalks slender, chaffy with thin narrow- 

 acuminate long-ciliate scales; fronds 5-7 inches long; the sterile 10 

 lines wide, oblong-linear, narrowed at the base, subacute at the apex, 

 beneath sparingly resinous-dotted, both surfaces and the edges webby- 

 pubescent with slender stellate hairs, veins mostly twice forked, vein- 

 lets crowded ; fertile fronds half the width of the sterile, acuminate, 

 stellate-pubescent above. Rio Blanco, in wet shady spots in ravines ; 

 August. (333.) — Fertile stalks 7 or 8 inches long ; sterile ones about 

 2 inches long. A. Miilleri, Fournier, has a similar pubescence of 

 very delicate 6-8-rayed stellate hairs, but is a much smaller plant 

 with oval-lanceolate fronds. More abundant specimens might possibly 

 show a connection between the two. 



PoLYPODiuii AUREDM, Linn., var. areolatum. Tequila, growing 

 in the crevices of rocks. (376.) — This fern is usually epiphytic, al- 

 though Galeotti collected it (P. fulvum, Mart. & Gal.) on calcareous 

 rocks. Liebmann found it only on trees, and questioned the accuracy 

 of Leibold, who reported it as growing on the graves of Indians.
