Hal). China-. Uongkong, J/hidcs and others ; Chusan, Ale.va/i(h'r. N.W, coast 

 of Formosa, U'ilford. — Allied as this species certainly is to M. triphyllum, our 

 species, ii. .'i, and nnnieroiis as are my specimens of both, 1 find each very constant 

 to its character, exhibiting no intermediate forms. 



2. M. ffi(/anteu/n, Metten, ; caudex?, stipes (in my only 

 specitnen) a foot long dark-l)ro\vn slightly pubescent upwards, 

 frond simple firm-meinbranaceous dark-green paler l)eneath 

 21 inches long 4 inches wide at the middle elongato-oblong 

 acuminated cuneato-subattenuated at the base oI)tusely sinu- 

 ato-dentate at tlie margin, costa stout downy, costules sui)hori- 

 zontal patent slightly curved U))wards slender .5 lines asunder 

 soriferous, transverse veins very numerous (as many as .57) 

 between the costa and margin slightly curved, the whole 

 length occupied by a linear continuous sorus, free veinlets 

 from the two united veins short never extending to those 

 above in my specimen. — Metten. in Fit. Lechl. p. 19. 



llab. Shady moist woods, St. Govan, Peru, Lechler. — Extremely different, as 

 Mettenius observes, from the only other known undivided Meniscium, M. simplex, 

 and a very fine and remarkable species. 



.3. M. triphyllum, Sw. ; caudex long creeping subulato-palea- 

 ceous, stipites pale-brown glabrous 4-5 inches long of the ste- 

 rile, a foot and more long of the fertile ones, fronds coriaceo- 

 membranaceous 3-5-foliolate subdimorphous, pinnce 3-5 

 inches long h an inch to 1 inch wide smaller and narrower in 

 the fertile frond, terminal pinna always the largest and long- 

 petiolate, all of them ol)long acuminate obtuse or cuneate or 

 subhastate at the base, the margin repando-dentate or nearly 

 entire, venation subj)ubesccnt beneath, soriferous veins 4-7-8 

 arched, the sori (apparently at least) solitary extending the 

 whole length of the transverse veinlet between the costules.
