Hab. Andes of Peru, Bolivia, and Chili, Haenke, Gillies, Mathews (San Luis), 

 n. 600, Tireedie (Tucuman), Cuming^ n. 600, Maclean, Brackenridye, Lechler, n. 

 2009. Island of Massa Fuera, Cuming, n. 1352. — Mettenius, in his monograph 

 of Polypodium, unites my P. Tweedianum with P. sporadolepis, Kze. I agree 

 most fully with him in a subsequent observation, that it should rather be referred 

 to P. macrocarpum, Pr. 



120. P. (Eupolypodium) murorum, Hook.; caudex rather 

 stout long creeping paleaceous with linear-subulate rather 

 crisped scales, stipites distant 4-6 inches long furfuraceous 

 as well as the whole under side of the plant with more or less 

 copious and- deciduous scales, fronds coriaceous 4-6 inches 

 long ovato-oblong acuminated pinnated pinnatifid at the acu- 

 minated apex, pinnee rather distant H inch long from a con- 

 tracted and subpetiolated base narrow oblongo-lanceolate 

 more or less deeply and regularly pinnatifid (rarely broader 

 near the base in the lowest pair of pinnae and then very 

 deeply pinnatifid), segments short subovate obtuse mostly 

 entire, veins sunk obscure, sori copious large subglobose one 

 or more on every segment. — Hook. Ic. Plant, t. 70 [very cha- 

 racteristic). P. sporadolepis, j3, Metten. Polypod. p. 67 

 {according to his reference to Hook. Ic. PL). 



Hab. Quitinian Andes, Jameson (on walls) ; on trees at Guayrapata, Spruce. 

 New Grenada, Purdie, Morits, n. 361, I/ardveg, Schlim, n. 449 and 81i; Bo- 

 gota, Holton. Caraccas, Linden, n. 507. — The much less compound frond of this, 

 with the almost regularly and not very deeply pinnatifid pinnae, are what chiefly 

 distinguish this from P. on nstum ; there are modifications, indeed, of these forms, 

 but I have never had a difficulty in distinguishing the two. 



121. P. (Eupolypodium) onustum, Hook.; caudex long 

 creeping branched thick as a duck's quill clothed with subu- 

 late imbricated scales, stipites distant 4-6 inches and more 

 long and as well as the under side of the plant subfurfura- 

 ceous with close-pressed deciduous ovate scales, fronds co- 

 riaceous 5-6 inches long oblong-ovate acuminate bipinnate, 

 primary pinnoB petiolate ovato-lanceolate, pinnules j-| of an 

 inch long scarcely petiolate oblong pinnatifid with short ovate 

 unequal rather obtuse entire or rarely sublobed segments, 

 venation sunk indistinct, sori very large prominent subglo- 

 bose one on almost every lobule and generally broader than 

 the segment. Hook. Ic. Plant, t. 749. Metten. Pohjpod.
