POLYPODIUM, § EUPOLYPODIUM. 211 



species with perfectly simple and undivided pinnae, wliich I take to he the really 

 normal state of the plant, as tlie Po/i/jjod. vulgare is the type of the P. Cambricum 

 and its various ahnorinal forms. The plant is most variahle in size, with fronds 

 not 3 inches long hy 2 wide, wholly pinnatifid, to a length of nearly li foot and 

 a diameter of 5 inches. In all, the scales of the upper side of the frond are 

 multifidly ciliate with a long spicule-hke apex, or formed of stellate hairs, all 

 more or less deciduous; those of the under side are suhovate, close-pressed, 

 ciliated, white with a dark disk. It is very like to prove an abnormal form of 

 P. squamatum, L. 



111. P. (Eupolypodium) lanosum, Fee; "fronds linear, 

 segments obtuse contorted opaque cartilaginous, when dry 

 subcontorted, clothed above with very long white hairs at the 

 base mixed with scattered scales, beneath densely clothed 

 with soft reddish long wool, superior segments alone fertile, 

 sori thick and confluent 3-4 in each segment, capsules ovate, 

 annulus with 12-13 articulations, spores thick oval." — Fee, 

 Gen. Fil. p. 237. Met ten. Poly pod. p. 69. 



Hab. "Chili. A singular elongated Fern, with short segments, resembling the 

 pods of some Ervtim or Vicia." Fee. 



112. P. (Eupolypodium) lepidopteris, Kze. ; caudex long 

 creeping stout clothed with ferruginous ciliated or glabrous 

 subulate scales, stipites distant short 1-3 inches long scaly, 

 fronds subcoriaceous stout generally very short 1-4 inches 

 long, fronds 3 inches to nearly H foot long 1-2 rarely 3 

 inches broad lanceolate or linear-lanceolate caudato-acumi- 

 nate subcoriaceous in general remarkably attenuated at the 

 base by the dwarfing of the pinnte often to within an inch of 

 the caudex pinnated below, above the middle more or less 

 pinnatifid, while young and the fronds not fully developed 

 clothed with very long glossy almost golden paleaceous hairs, 

 in age the clothing is singularly variable sometimes composed 

 chiefly if not entirely of the ovate ciliated hair-pointed ap- 

 pressed peltate pale scales brown in the disk so common, to 

 this group, more frequently accompanied with long pa- 

 leaceous hairs more or less abundant and very coj)ious and 

 persistent on the under side varying in colour from ferrugi- 

 nous to white, pinnae approximate varying extremely in 

 length and breadth horizontally patent broad-adnate and 

 more or less decurrent at the base ovate and frequently sin- 

 gularly undulato-sinuate at the margin at other times oblong 

 or oblong-linear or subspathulate and entire, lowest ones 

 singularly and gradually abbreviated, (venation oi Marginuria, 

 Pr.) sori in two rows intermediate between the costule and
