 Peruvianuni). Andes of Peru, Herb. Ruiz, n. 58 (K/otzsch). — I give Mettenius's 

 character ratlier than that of tlie original describer, Dr. Klotzsch, to whom, 

 nevertheless, I am indebted for the only specimen I possess, for it seems to be 

 the most accurate. If there be any real distinction between this and P. Peru- 

 vianum, which Metteuiiis very properly doubts, it must be sought in the slender, 

 filiform, creeping, scaleless caudex, a foot long in my specimen, with small fronds 

 not 2 inches long and 2-3 inches apart, whereas Klotzsch describes the fronds as 

 cffispitose. 



58. P. (Eupolypodium) PtT?/yiawz<m, Desv. ; caudex creep- 

 ing setaceous with blackish subulate scales or often (perhaps 

 in first year's plants) small and inconspicuous, apparently a 

 mass of matted fibres, stipites ^-3 inches and even more 

 long scattered and distant on the creeping caudex, tufted in 

 the absence of distinct caudex patently villous, fronds 3-5 

 inches long ^ of an inch wide coriaceous firm linear-lanceo- 

 late acuminate and quite caudate at the apex gradually ta- 

 pering at the base deeply to the rachis })innatifid, segments 

 subtriangular-ovate obtuse with the lower margin decur- 

 rent and a few scattered hairs on the margin and on the 

 costule entire or rarely sinuated, veins immersed inconspicu- 

 ous, sori rather large 2-4 on each segment with a few hairs 

 among the capsules. — Desv. Mem. Soc. Linn. vi. p. 321.

 figure in Ic. Fil. well represents the caudicate form of this plant, but the stipites 

 are longer than in any of our other specimens. Most of those from New Granada 

 have shorter stipites and no really visible caude.x.
