crenato-serrate, soil intennediate between the margin and 

 costa, involucres glabrous at first closed afterwards bursting 

 at the to)) with an irregular roundish contracted 0))ening, 

 stipes and rachis with lew snuiU deciduous hair-like scales.

Tiab. Guatemala, Mr. Skinner. — Neailj' twice the size of the preceding, 

 with all the herbaceous portion glabrous ; the segments of the j)inniE more 

 remote, more serrated or erenate. Sori pale brown, membranaceous, re- 

 maining long closed or entire at the top, then bursting and persisting 

 with a contracted loose mouth. 



3. W. Pertoid/ut, Hook. ; fronds oblong-lanceolate bipin- 

 nate piloso-glandulose, primary pinnie nearly opposite remote 

 sessile, ovate-acuminate, pinnides opposite or rarely alternate 

 oblong obtuse sessile and decurrent so that the rachis is wing- 

 ed somewhat pinnatifid with shallow bicuspidate lobes, sorus 

 solitary in each lobe subglobose at first entire afterwards 

 bursting at the top w ith an irregular contracted mouth, stipes 

 and main rachis glabrous. (Tab. XXI. B.) 



Hab. Shady places, Iluaraantanga, Andes of Peru, Mutheivs, n. 602. — A 

 very distinct species, and the tallest of any I am acquainted with, the frond 

 with a portion of the stipes being 14 inches long. This frond is twice pin- 

 nated, the pinnules almost all opposite, very patent, rather remote, cut in a 

 pinnatilid manner into a number of small lobes, which are bicuspidate, ter- 

 minating in two, rarely three, sharp teeth. 



4. W. (Physcmatium, Kze.) Ciimiiujiaua, Kze. ; " frond 

 narrow-lanceolate deeply pinnato-pinnatifid, pinna? somewhat 

 remote sessile lanceolate subacuminate rather obtuse glabrous 

 above, beneath on the costa veins paleaceo-hirsute, segments 

 oblong rounded glanduloso-dentate decurrent, sori solitary 

 upon the teeth, involucres glabrous, rachis and stipes (of mo- 

 derate length) subglabrous purple." Kimze, Anal. Pterid. 

 p. 43. 



Hab. " Probably in Chili," Cumimj, (in Herb. Ktmte). — " Between W. 

 Physematinm) incisa and Perriniana, but different from both. Stipes 

 3 inches, frond 7^ inches long, 2 broad. Lower pinnie and superior ones 

 smaller. W. incisa differs in the narrower pinnae piloso-glandulose, obtuse, 

 obtusely toothed, in the involucres being at length laciniated, the laciniEe 

 retlexed. P. Perriniana differs especially in the pinna l)eing deltoideo- 

 ovate, minutely glanduloso-pilose, in the involucres being deeply cut, and 

 the stipes and rachis chaffy." — I place this in the present group rather 

 than the following, though the species is quite unknown to me, because in 

 contrasting the involucres with tliose of the W. incisa and Perriniana (be- 

 longing to the next group) the author speaks of the deeply cut involucres of 

 the latter, and their spreading segments, as if a contrary character existed 

 in U'. Cuntini/iana. It is probably allied to our W. Peruviana, and very 

 likely not (rom Chili : at least I possess no such plant from Cuming gathered 

 either in Chili or in Peru, and I had the choice of his collections immedi- 

 ately on his return from tiiose countries.
