mineous-brown and a little scaly at the base. (Tab. CXXIII.

Hab. East Indies : Mishmee, Griffith. — I have never seen this in any collec- 

 tions but those of tlie late Mr. Grittith from Mishmee. The several specimens 

 are e.\tremely uniform in their character, only varying a little in size, and in the 

 greater or less number of compound pimue at the base of the frond, from one to 

 three pairs; and I can refer to no known species with which it can be con- 

 founded. 



*** Fronds variously divided, rarely once pinnate with the pinnae pinnatifid ; 

 more frequently 2- 3- or 4-pinnate, especially below. — This section includes a 

 heterogeneous group, which it is impossible to separate and characterize, so 

 varied is the ramification even in one and the same species. 



25. Pt. (Eupteris) Madagascarica, Ag. ; frond bipinnate, 

 pinnules distant on rather long petioles linear-lanceolate nar- 

 row acuminate serrated at the sterile apex, inferior ones (on 

 the branch) subpinnate, pinnules few 1-3 short, veins stout 

 (for the size of the pinnules) forked, veinlets spreading, invo- 

 lucres subintraniarginal very narrow membranaceous, rachis 

 slender subflexuose scabrous beneath. (Tab. CXXII. A.) — 

 Ag. Pterid. p. 17- 



Hab. Madagascar, Bojer, in Herb. Nostr. — Agardh describes this as the third 

 species of a singular form of Pteris ; the two others being Pt. laurea and 

 Pt. (Litobrochia) triphylla ; peculiar to Madagascar, more compound than they, 

 subtripinnate. Pinnae elongated, nearly a foot long ; petioles nearly 3 lines long. 

 The pinnules have a tendency to the ternary division, also characteristic of the 

 two just mentioned, but eventually to become pinnate. The form of the pinnules 

 themselves is also different, elongato-lanceolate, much attenuated and lengthened 

 at the apex, and there coarsely serrated. The veins are all forked, their branches 

 patent. Rachis (and also the stipes ?) very scabrous beneath. The branch of 

 this may be from a very compound Fern, and the rachis seems to have a dispo- 

 sition to be scandent and the pinnae to be refracted. It is a very peculiar species, 

 as may be seen from our figure. 



26. Pt, (Eupteris) tr'iphyUa, Ag. ; frond (a solitary and ste- 

 rile specimen) \\ foot long oval membranaceous glossy bi- 

 subtripinnate, all the pinnse long-petiolate, superior ones and 

 secondary pinnse mostly triphyllous rarely pentaphyllous, 

 pinnules oblong terminal ones very much elongated (2-5 

 inches long) all obtuse subcrenate a little serrate towards the 

 apex, veins forked once or twice or more on one and the same 

 pinnule both free and united by arched (or angulato-arched 

 veins) next the midrib (as in Campteria, Ag.), rachises slen- 

 der smooth tawny. (Tab. CXXXI. B.)—Ag. Pterid. p. 16. 



Hab. Madagascar, Dr. Lyall (in Herb. Nostr.). — Professor Agardh's descrip- 

 tion {I.e.) from our specimen is very faithful. "The frond is probably large, a 

 foot and a half long. Rachis brown, very smooth, with about eight pairs of pin- 

 nae. All the pinnae petiolate, petioles an inch long, at length pinnated, pinnules
