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 

 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 West Indies to Brazil and Peru. Doubtfully distinct from 

 M. reticulatum. 



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

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

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

 rachis and both sides naked or nearly so ; main veins l|-2 lin. apart ; areolce 

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



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

 urophyllum, with which Hooker united it. M.villosum, J. Sin., and M. Parishii, Bed- 

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

 M. Cumingii, Fe"e, is a glabrous form, with narrower and thinner pinnae, the lateral 

 ones few or sometimes absent. 



10. M. reticulatum, 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. sorbi- 

 folium, Willd. (M. Kapplerianum, F^e), is a form with narrower pinnae than usual, the 

 lower ones slightly stalked. 



GEN. 55. ANTROPHYUM, Kaulf. 



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

 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. sulfalcatum, 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 each side the 

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

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

 Cent. t. 79. 



Hab. Borneo, Fiji, and Samoa.
