 Veraguas, Seemann, n. 1581 ; Guatemala, Skinner ; New Granada, Linden, n. 1495 ; 

 Venezuela, F(?w«?/er, n. 2G4 {caudex 2 inches thick, including the dense paleaceous 

 clothing; young plants with the stipes and under side of the costa black-crinite with 

 the copious scales, while the rest of the frond, of a bright-green, is quite naked ,■ the 

 veins not unfrequently anastomosing) ; Andes of Peru, M' Lean, Mathezvs; Ecuador, 

 forests on the west side of Pichincha, Jameson (splendidly erinaceous). — On the 

 identity of this fine but variable Fern with the African u4. hybridum, it behoves 

 us all to speak with caution. There is nothing improbable nor unusual in the 

 same species inhabiting such widely remote localities ; and'considering the great 

 difference of soil and climate, — the one inhabiting lofty volcanic mountains of 

 Africa, the other the moist forests of tropical America,- — it is possible that much 

 of the difference may be due to local circumstances. 



36. A. (Elaphoglossum) Hystrix, Kze. ; "frond linear- 

 oblong attenuated at the base acuminated at the apex margi- 

 nate glabrous at the margin densely curvato-paleaceous, costa 

 stout canaliculate above sparingly more densely beneath 

 horrid with black rigid deflexed scales (sterile only)." — Kze.

Hab. Peru, Pampayaco, Pffijw/if^r. — " Stipites 2\ inches long, reddish, lineari- 

 paleaceous at the brown base, above, as well as the costa, clothed with lanceo- 

 lato-subulate black scales; fronds 15-20 inches long, above deep, beneath pale 

 green, parallelo-patenti-villose ; scales of the margin of the frond minute, brown, 

 from a subovate base, subulate, curved." Kze. — Surely this cannot be far re- 

 moved from some of the forms of A. scolopendrifolium ? I possess no authentic 

 specimen of the plant. 



37. A. (Elaphoglossum) undulatum, Willd. ; " caudex 

 creeping with the scales lanceolato-subulate brown," stipites 

 5 inches long (equal in the sterile and fertile plant) densely 

 paleaceo-villous with subulate ferruginous horizontal scales 

 not more than 1 line long; sterile frond membranaceous 

 subpellucid 10 inches long 2 inches wide oblongo-lanceolate 

 obtusely cuneate at the base gradually narrowing upwards 

 but in my specimen notched at the apex and proliferous on 

 the costa, the margin entire ciliated with setaceous soft hairs 

 or scales and the same are scattered over the surface of the 

 frond and more copiously on the slightly prominent and 

 reddish costa beneath, veins manifest singularly wide (not 

 less than 2 lines apart) often once- or twice-forked; fertile 

 frond 3 inches long 8 lines wide oblongo-cuneate at the base 

 bluntly acuminate, the margin and costa decidedly ciliated. —
