)Iab. Andes of Ecuador, Jamoson, Hartweg, n. 1501, Spruce, n. 5327. Parano

 Met ten.). — This belongs to the same group as P. Frederic ksthaliavnm and P. 

 muro)~um ; it is much less finely divided tlian the former, and more compound 

 than the latter, yet very distinct, I think, from both. Yce's P. rnacrosorum is 

 identical with this, and equally with my original s|)eeiniens of /'. onustum from 

 Quito (Jamenon), and is an excellent representation of the narrowest-segmented 

 form, while my figure exhibits that with the broader and shorter segments. 

 Mettenins, singularly enough, as it appears to me, places my P. Tweediamtm, Ic. 

 PI. t. 86, and P. mtirornm (n. 120), together with P. macrosortim of Fee (which he 

 therefore considers distinct iromomistnm), as separate varieties of P. sporodolepis 

 of Kze. Herb, (a previous unpublished j)lant), possessing three difterent kinds of 

 venation and of insertion of the sori ; viz. a. P. Tweedianum, Hook., " nervi 

 repetito-furcati ; rami antici apice vel dorso medio soriferi ;" j8. P. murorum, 

 Hook., " laciniaj (pinnarum) nervuni repetito-furcatum excipientes, plerumque 

 ad furcaturam rami antici soriferi;" y. P. macrosorum, Fee, " lacinia: nervum 

 furcatum excipientes, in dorso vel apice rami antici soriferse." The nature and 

 opacity of the frond renders it very difficult to confirm the correctness of these 

 distinctions, and unnecessary, inasmuch as there are, as appears to me, tangible 

 characters, independent of them, for specific distinction. 



122. P. (Eupolypodium) Fredericksthalianum, Kze.; cau- 

 dex long creeping paleaceous nearly as thick as a writing pen, 

 stipites 4-G inches long rather stout and as vvcU as the 

 whole under side of the plant furfuraceous w^th pale-coloured 

 ovate toothed silvery appressed scales, frond subcoriaceous 

 10-16 inches long ovato-oblong or oblong 2-4 inches broad 

 bipinnate quite naked on the upper side, primary pinnee 

 subovate acuminate petiolate, pinnules all linear obtuse ^ an 

 inch and more long distant with generally short spreading 

 obtuse subspathulate segments, veins solitary costuliform fol- 

 lowing the course of the segments, sori subglobose terminal 

 on a veinlet. — Kze. in Schk. Fil. Supjjl. ii. p. 55. t. 123.

Hab. Guatemala, Linden {Kze.) ; Vera Paz, Salvyn. Mexico : Chiapas, Linden, 

 n. 1528 and 1540 {in Herb, nostr.). — A very elegant Fern; but I fear tlie two 

 supposed species described and figured by Kunze, in reality are but slight varieties 

 of one and the same. 



**** Fronds pinnate, or pinnatifid only towards the apex. 123-143.

123. P. (Eupolypodium) teneilnm, Forst. ; caudex very 

 much elongated scandent woody, the younger portion clothed 

 with black ovate scales bordered with Ijrown, stipites 

 scattered distant generally short 1-3 inches long tawny
