1. E. Kaulfussii, J. Smith (Marattia alata, Raddi; M. Kaulfussii, Kunze ; M. laevis, Kaulfuss). —An orna¬ 
mental evergreen stove Fern, from Brazil. Fronds glabrous, triangular, three-branched, grass green, from three 
to four feet high ; branches tripinnate ; ultimate pinnules ovate or oblong obtuse, sessile membranous, pinnatifid, 
obliquely truncate at the base, and obtusely lobed at the margin. Midrib of pinnae and pinnules winged through¬ 
out. Stipes roundish, about half the length of the frond, and, as well as the pinnae, swollen at the base and 
indistinctly articulated. 
t NGIOPTERIS, Hoffman. —Named from aggeion , a vessel, and pteris, a fern; alluding to the formation of the 
sori. 
IP Sori linear, continuous, compound, submarginal. Spore-cases obovate 
sessile emarginate, laterally confluent, and definitely arranged in two opposite 
series ; each series containing from five to seven distinct entire cells ; each 
cell opening by a vertical slit internally. Sporangiferous receptacle medial. 
Veins simple or forked, free. Fronds large, stipitate, bi-tripinnate, from 
six to ten feet long. Rhizome large, fleshy, subglobose.—Only a solitary 
species of this genus is at present in cultivation; it is one of the most robust- 
growing of herbaceous Ferns, and so precisely coincides with Marattia, in 
aspect, habit, and venation, and in the circumscription of the fronds, that it 
cannot be determined with certainty even by the best pteridologists, except 
by the aid of the fructification. The geographical distribution of plants is 
frequently found to be a valuable auxiliary in the determination of genera 
or species; and so in the present instance, whilst Angiopteris is confined to 
the Fast Indies, no species of Marattia, according to Dr. "Wallich, has been 
detected there; though one if not two species are found in the islands 
of Mauritius and Bourbon. The 
genus is readily known when in 
fructification by the spore-cases 
being definitely disposed in two 
opposite rows, each row laterally 
confluent, each spore-case distinct, 
and opening with a vertical slit on 
the inside. Fig. 94 represents a 
pinnule of A. evecta (med. size), and 
a sorus (magn.) 
1 . A. longifolia , Greville et 
Hooker ? (A. evecta, Hort.) —An 
ornamental evergreen stove Fern, 
from Ceylon. Fronds glabrous, 
bi-tripinnate, from six to ten feet 
Fig. 94. 
high, deep olive green ; pinnules lanceolate-petiolate, five to ten inches 
long, coriaceous, shining, serrate at the apex, roundish or obliquely 
truncate at the base, and finely crenate-serrate at the margin. Stipes 
terete, three to four feet long, very stout, and scattered over with woolly 
scales, especially when young. Both stipes, pinnae, and pinnules are 
swollen at the base, and indistinctly articulated. Midrib of pinnae mar- 
ginate, or slightly winged. This plant was introduced to Kewin 1845, 
and has been recently imported, by Messrs. Rollisson of Tooting, from 
Java.

>ANiEA, Smith. —Name commemorative of Pierre M. Dana, a writer 
on the plants of Piedmont. 
Spore-cases linear, biserial, multilocular, each cell opening by a 
circular pore. Sporangiferous receptacle occupying nearly the whole 
length of the venules. Veins forked ; venules direct, parallel, arcuate on 
their apices, where they anastomose with a cartilaginous margin. Fronds 
of two kinds, sterile and fertile, simple or pinnate, from one to threefeet 
long ; pinnae lanceolate, entire or serrate on the margin. Fertile fronds 
usually contracted, and densely sporangiferous throughout the under sur¬ 
face. Rhizome thick, fleshy, decumbent, and creeping.—Two or three 
minor characteristics exhibited by this genus serve to distinguish it from 
the other portion of Marattiaceae, namely, the curved venules anastomos-

ing with the cartilaginous margin, and the decumbent rhizome. The essential character, however, consists in the
