8. M, serratum, Cav. ; st. 1-3 ft. 1., stout, brownish, glossy ; fr. 3-4 ft. or 

 more 1., 1 ft. or more br. ; pinnae 1-3 in. apart, 6-12 in. 1"., \-2 in. br., oblong- 

 lanceolate, the base cordate or cuneate, the apex acuminate, the edge finely 



V toothed ; texture subcoriaceous ; both sides naked ; main veins ^ in. apart ; 

 areolce 12-20 between the midrib and edge. — Hk. Sp. 5. p. 165. M. palustre, 

 Raddi. 



Hab. Mexico and AVest Indies to Brazil and Peru. — Doubtfully distinct from 

 M. reticulatum. 



9. M. cuspidatiim, Blume ; st. 1-2 ft. 1., stout, naked ; fr. 2-4 ft. 1., 1 ft. or 

 more br. ; pinnce 6-9 in. 1., 1-3 in. br., tlie point acuminate, the edge nearly 

 entire, the base cuneate or rounded, often slightly stalked ; texture subcoriaceous ; 

 raclds and both sides naked or nearly so ; main veins \\-2 lin. apart; areolce 

 6-20 between the midrib and edge. — Blume, t. 45. 



Hab. Himalayas, Malaccas, Philippines. — Very probably a Meniscioid form of Polyp. 

 uropliylluTii, with which Hooker united it. M. villosum, J. Sm., and M. Parishii, Bed- 

 dome, have pubescent and more herbaceous pinnae than the form described above, and 

 M. Ciimingii, F^e, is a glabrous form, with narrower and thinner pinnae, the lateral 

 ones few or sometimes absent. 



10. M. reticidatum, Sw. ; st. tufted, 1-3 ft. 1., stout, brownish, glossy ; fr. 2-4 

 ft. 1., 1 ft. or more br. ; pinnae 6-12 in. 1., 1-4 in. br., the apex acuminate, the 

 edge entire or subrepand, the base rounded or cuneate ; texture subcoriaceous ; 

 rachis and both sides naked or slightly pubescent ; main veins 1-1| lin. apart ; 

 areolce 8-12 between the midrib and edge. — Hk. Sp. 5. p. 165. 



Hab. Mexico and West Indies to Brazil and Peru. — M. macrophyllum, Kze., appears 

 to be a form with a few large pinnae. M. molle, Mett., gathered in New Granada by 

 M. Triana, has the rachis and under surface softly hairy, and quite entire pinnae 1 ft. 1., 

 1 in. br., truncate on the upper and rounded on the lower side at the base. M. sorhi- 

 folitmi, Willd. (M. Kapplerianum, F&), is a form with narrower pinnse than usual, the 

 lower ones slightly stalked. 



CrEN. 55. Antrophyum, Kaidf. 



Sori carried along the veins, imperfectly reticulated. A small genus of closelj/ 

 allied species almost restricted to the tropics, all with simple fronds of firm but 

 fleshy texture and copious uniform, hexagonal areolce. Tab. VI. fig. 55. 



* Sori sunk in a distinct groove. Sp. 1-8. 



1. A. lineatum, Kaulf. ; fr. 6-12 in. 1., ^-| in. br., the point acute, the edge 

 entire, the lower half narrowed very gradually to the base ; a distinct slender 



^ raised midrib throughout ; areolce very long and narrow ; sori in 2-3 almost 

 continuous lines on each side of the midrib parallel with it, sunk in deep furrows 

 with raised edges. — Hk, Sp. 5. p. 175. Polytsenium, Desv. 



Hab. Cuba and Mexico to Ecuador and Brazil. — Habit of Vittaria, but the sori multi- 

 serial. 



2. A. sid)falcatum. Brack. ; fr. 6-12 in. 1., J-| in. br., the point acute, the edge 

 entire, the lower part narrowed very gradually to the base or a short stem, an 

 indistinct midrib in the lower part ; areolce vertical, about two on ^ach side the 

 midrib, several times longer than broad ; sori moderately immersed, in 2-4 long 

 interrupted lines, hardly uniting. — Hk. Sp. 5. p. 175. A. Brookei, Hk. 2nd 

 Cent. t. 79. 



Hab. Borneo, Fiji, and Samoa.
