6. Elaphoglossum longipes, Sp. Nov. (Tab. 9.) 



E. rhizomafe repente dense squamoso; stipitibus elongatis gracilibus parce 

 squamosis; frondibus lineari-lanceolatis utrinque attenuatis supra 

 squamosis, fertilibus rninoribus lanceolatis obtusis; squamis oblongo- 

 lanceolatis spinuloso-dentatis ; venis patentibus ; venulis plerumque fur- 

 catis. 



Hab. Banos, Andes of Peru. 



Rootstock long and creeping, about the thickness of a crowquill, 

 covered with narrow, lanceolate, blackish, rigid, spinulose-dentate 

 scales. Stipes of both kinds of fronds equal in length, from 7 to 8 

 inches long, slightly compressed, squamose, the scales covering about 

 half of the surface. Sterile fronds from 3 to 5 inches long, and about 

 6 to 8 lines broad, someivhat linear-lanceolaie and attenuate at base, the 

 upper surface only covered with oblong-lanceolate, spinidose-dentate 

 scales; the fertile shorter, 2£ to 3 inches long, lanceolate, obtuse, slightly 

 attenuate at the base, squamose on the upper surface. 



This is related to Acrostichum lepvdotum of Willdenow ; but it differs 

 in the fronds being squamose only on the upper surface, and also in 

 the greater length of its stipe.
