-li CHAEACTEES OF TEIEES AXD GEXEKA. 



different forms of one species. In the " Synopsis Filicum " 

 a fourtli species is described as belonging- to this section, 

 under tlie specific name of " Michleriaiia," a native of iSTew 

 Granada. It is described as being- pinnate, 12 to 15 inches 

 in length, the pinnas 3 to 5 inches long, the reins forming 

 hexagonal areoles, with free included veinlets, which seems 

 to indicate its affinity -svith Diciijoxiphium ; its mode of 

 vernation is not described, and probably Tchen that is 

 known it will be found not to belong to this tribe. 



152. — (tUEEKIA, J. Sm. 

 Schizoloma sp. Gaud., Isoloma, Fee, Lindsai/a, Hooh. 



Caudex slender, sarmentose. Fronds lanceolate, pinnate, 

 6 to 9 inches long, smooth. Pinnre. ovate oblong, J to f 

 of an inch long, falcate, sessile, articulate with the rachis ; 

 costiB slightly excentric. J'eins reticulate, obscure. Eecep- 

 iacles marginal, immersed in an indusoid groove, forming a 

 linear continuous sorus. 



Type. S'chizoloma Gueriniana, Gaud. 



Illust. Gaud, in Voy. de L'Urinie, t. 18. 



Obs. — The species on which this genus is founded differs 

 in general appearance from the true species of ScJiizoloma, 

 and especially in the pinnas being articulate with the rachis. 



It appears to be a rare Fern, as there is no specimen in 

 the Hookerian herbarium ; but the nature of the stipes of 

 fronds in my herbarium* induces me to believe it to have 

 articulate vernation. 



The presence of white dots on the upper side of the 

 pinufe gives it some claim to be ranked with L<oloma and 

 Nephrolepis, but till more of it is known I retain it here. 



Sp. G. articulata, J. Sm. {S'chizoloma Gueriniaaa, Gaud.) 



Native of the Molucca Islands.
