356 CHARACTERS OF TRIBES AND GENERA. 



rangia sessile few, seated in concave segments formed by 

 the revolute margin, globose, opening vertically on their 

 exterior side. 



Type. Mohria thurifraga, 8w. 



Illust. Hook, and Bauer Gen. Fil., t. 104, B ; Moore Ind. 

 Fil., p. 93, A ; J. Sm. Ferns, Brit, and For., fig. 145 ; 

 Hook. Syn. Fil., t. 8, fig. 66. 



OBS. This genus is founded on a solitary species, a 

 native of South Africa and Madagascar. 



Sp. M. thurifraga, Sw. (v v.) (M. achillcefolia, Lowe's New 

 Ferns, t. 42, B.) 



OBS. This Fern much resembles some species of Cheilan- 

 thece, the concave segments containing the sporangia being 

 similar to Myriopteris. 



209. SCHIZ^A, Sm. (1793). 



Hook. Syn. Fil. 



Vernation fasciculate, erect, acaulose, rarely distant. 

 Fronds linear, simple, stipitiform, simply forked or flabellate, 

 2 to 20 inches high. Veins forked, free ; fertile appendices 

 terminal, pinnate, cristseform ; margins of the segments 

 involute, each bearing on its inner side two compact rows 

 of sessile oval sporangia, attached by their base, and 

 opening vertically. 



Type. Schizc&a pectinata, Smith. 



Illust. Hook, and Bauer Gen. Fil., t. 19 ; Moore Ind. 

 Fil., p. 91 B. ; J. Sm. Ferns, Brit, and For., fig. 146 ; 

 Hook. Syn. Fil., t. 8, fig. 64. 



OBS. This is a curious genus, differing from Anemia in 

 the sporangia being borne on crestlike terminal spikes, 

 which being resupinate give the appearance of the spo- 

 rangia being produced on the upper surface.
