 Herb, nostr. — ^My autbentic sjiecimcus of Mettenius (from Tovar) I sbould bavc 

 been disposed to refer to tbe P. apiculatum, Kl., or, what I believe is the same 

 tiling, a small var. of P. Planmla. It resembles a good deal Fee's figure of the 

 following speeies, but does not accord well with the description. The two are 

 from the same country. 



50. P. (Eupolypodium) leptostomum, Fee ; " fronds nar- 

 row, stipes short brown clothed with capitate hairs (vis- 

 cose?), rachis of the same colour but clothed with acute 

 hairs, segments linear-lanceolate glabrous acute rigid erect, 

 lateral veinlets simple short, capsules lax 5-7 central, spo- 

 rangia rounded, ring of twelve joints, prominulous at the open- 

 ing, spores ovoid, caudex erect woody bearing very long brown 

 radicles." — Fee, 7me Mem. Foug.Nouv. p. 58. t. 2,1. f. 2.

 inches long pinnatifid broad-linear membranaceous stipitate 

 adpressedlv scabrous viscidulous, segments 3-5 lines long 

 lanceolato-linear subobtuse horizontal alternate distant mul- 

 tisorous, veins pinnately branched branches short soriferous, 

 sori small dirty-brown uniserial opposite, stipes and rachis 

 filiform brown at length glabrous." Kl. inLinncea, xk. p. 377*

 feet, Schlim, n. 843. — Among other difficulties attending the study of tbe Ferns, 

 is that arising from not finding the descriptions of authors tally with their own 

 specimens. In the present case of the plant which is authority for tbe species, I 

 possess an original from Klotzsch as 332 of Moritz, and tbe same is quoted by 

 Mettenius ; but my specimens are not scabrous, nor have they linear (Metten.) or 

 linear-lanceolate (Kl.) segments, but rather oval-oblong ; and certainly none of 

 my specimens approaches 1-1. i foot in length, with segments l.V inch long, ac- 

 cording to Mettenius, as may be seen by our figure. The species is remarkable 

 for tbe long purplish hairs on the stipes, and still longer on the margins of the 

 segments. 



52. P. (Eupolypodium) Jamesotioides, Fee ; " surculus 

 slender erect, stipes short filiform, fronds linear multipartite 

 fasciculate viscid nearly glabrous with the evolution at the 

 apex indefinite, segments diminishing in size from the base
