On our first investigation of this species, we were disposed to consider it an undescribed one; | 
but upon comparing it carefully with the character of the P. Peruvianum of Desvaux in the work 
above quoted, we believe it to be the same; for that author has correctly pointed out the marks by 
which it is distinguished from P. trichomanoides,—namely, its elongated stipes clothed with long 
spreading hairs. MM. Desvaux, however, has omitted to notice the long spreading hairs on the 
underside of the frond; and instead of the fronds being c«spitose, they decidedly arise from a long 
creeping caudex. |
