This plant is a foot and a half long. Frond linear-oblong, with patent short primary pinnae of a delicate 
membranaceous texture. Sori one or two on each lobe. 
8. Asplenium diplazioides ; glabrum, fronde bipinnata, pinniilis subremotis paten tibus 
lanceolato-acuminatis pinnatifidis, lobis ovali-oblongis obtusis crenato-lobatis, soris numero- 
sissimis obliquis ssepe geminatis. 
Neither among the many Asplenia that have been published, nor among the Diplazia, do we find any 
species that accords with this, which, indeed, partakes as much in the character of the one genus as of the 
other. The fronds (and we have no perfect stipites) are broadly, almost deltoidly ovate; the divisions 
rather remote; the primary ones broadly lanceolate, 4-6-8 inches long; the secondary ones or pinnules 2-3 
inches long, and half an inch in breadth. Fructifications very copious, at length almost confluent. 
9. Asplenium ambiguum? Sw. — Schkuhr, Fil. t. 75. a. h. 
Without the lower part of the frond, which is wanting in our specimen, it is difficult to say if this be 
decidedly the A. ambiguum of Swartz. 
10. Asplenium Poiretianum ; frondibus fasciculatis decompositis utrinque glabris (2-3 
pedalibus), foliolis pinnatis, pinnis ovato-lanceolatis acutis pinnatis basi superiore auriculi- 
formibus, pinnulis lineari-lanceolatis subcoadunatis acutis serrato-pinnatifidis rachi ramu- 
lisque submarginatis margine laciniato-squamuliformibus, soris subreniformibus minutis 
costae mediae approximatis, caule subarboreo prostrate. Gaud, in Freyc. Voy. p. 321. t. 13. 
1. Darea flaccida. Willd. Sp. PL p. 295. pinnis subbipinnatifidis. 
This may perhaps prove to be a species distinct from D. flaccida. It is often two feet or more in height. 
The fronds are very flaccid ; the pinnae have the segments (which are linear and bearing one sorus in D. flac- 
cida') again pinnatifid with two or three segments, and bearing two sori. 
1. Sadleria cyatheoides; pinnulis remotiusculis enerviis, raebi nudo glaberrima. — Kaulf. 
Enum. Fil. p. 162. 
2. Sadleria ; pinnulis approximatis nervosis, rachi paleacea. Hook, et Arn. p. 75, 
hujusce operis. 
See page 75 of the present volume, for some remarks on this plant. 
1. Pteris pedata. Willd. Sp. PI. p. 358. Langsd. et Fisch. Ic. Fil. p. 17. t. 20. 
This is indeed a very variable plant, yet easily recognised in its dififerent states by the peculiar ramifica- 
tion of the frond. The P. geraniifolia of Raddi, Fil. Bras. t. 67, tolerably correctly represents the state of 
the single specimen of this plant in the Collection. 
2. Pteris alata; frondibus (3-4 pedal.) tripinnatifidis tetrapinnatifidisve, pinnis oppo- 
sitis, pinnulis lineari-lanceolatis irregulariter lobato-pinnatifidis acuminatis, laciniis oblongo- 
lanceolatis subobtusis integris plerumque abortivis, inferioribus dentato-subcrenulatis, rachi 
late alata, stipite triangular! atro-rubro basi paleaceo. Gaud, in Freyc. Voy. p. 391. t. 19,

1. Doodia Kunthiana; frondibus fasciculatis lanceolatis subacutis serrulatis superioribus 
adnatis inferioribus petiolatis basi cordatis infimis subauriculatis, stipite elongato rugoso 
basi squamoso. Gaud, in Freyc. Voy. p. 401. t. 14.
