GENERA OF FERNS. 393 
Obs. I have been induced to designate this as a genus dis- 
tinct from Marattia, in order to mark the peculiarity of its 
pedicellate multilocular sporangium, which has already been 
noticed at page 190 of the preceding volume, where its ana- 
logy to Spheropteris is shown. The name Eupodium 1 have 
adopted from a manuscript of Mr. Brown’s, originally in- 
tended for Spheropteris.

Veins forked. — Venules direct, parallel, their apices arcuate 
and anastomosing at the margin. Sporangiferous receptacle 
occupying the whole length of the venules. Sporangia 
linear, biserial, multilocular, each cell opening by a circular 
pore. 
Fronds pinnate, rarely simple, 1 to 3 feet in length. Pinne 
lanceolate, entire or serrate. Fertile fronds usually somewhat 
contracted, densely and compactly sporangiferous over their 
whole under surface.

Obs. The compact parallel linear sporangia, opening by two 
rows of pores, readily distinguish this genus from the two 
preceding, and, as in them, I consider the multilocular spo- 
rangia of this genus to be formed by two series of united 
sporangia, not separating lengthwise into two parts or valves, 
Which is the case in Marattia.

Veins costeform, parallel. Venules compound, anasto- 
mosing with free veinlets terminating within the areoles. 
Sporangiferous receptacle compact, round. Sporangia rotate, 
multilocular; cells opening by an oblong slit on their inte- 
rior side, 
Fronds ternate, broad, stipitate; segments oblong-elliptical,
