versus nune bifurcatis suleatis subbullatis, subtus coneavis rigidis; soris 
copiosis ferrugineo-fuscis in lacinia quaque 12—16 biseriatis venarum 
alis insertis grandibus densis, dein confluentibus, totas fere lacinias 
apice excepto occupantibus ; indusio tenerrimo primo cupulzformi mem- 
branaceo, mox bifido et laceratim evanido; rhachibus secundariis et 
costis costulisque dense vineo-tomentosis et paleis ferrugineis nitidulis 
obtectis.— This species has some affinity to C. crenulata, Bl., but differs 
from it: laciniis acutioribus profunde crenato-serratis, supra bullatis 
rigidioribus, tomento vineo rachium et preprimis sororum copiosorum 
indusio tenuissimo membranaceo, dein subevanido. Stem 40 feet high. 
This Fern grows at the height of 8000 feet on the Gedeh. 
C. leukophaés, Hsskl.; arborea (10—15^, stipite rhachique muricu- 
lato-aculeatis, fronde tripinnatifida coriacea siccando supra candida 
glabra; pinnis oblongo-lanceolatis acuminatis plerumque petiolatis, - 
pinnulis lineari-oblongis acuminatis basi inæqualiter truncatis valde 
profunde pinnatifidis, laciniis lineari-oblongis acutis margine ad apicem 
Serrato-erenatis reflexis, venis pinnatis furcatis, soris ad alam venarum 
insertis globosis, indusio membranaceo lucidulo globoso mox irregula- 
riter lacero et dein toto evanido.—Mr. Teysmann, who superintends 
the Botanic Garden of Buitenzorg, found this Fern on the Dileng 
mountains. Differt a C. dealbata, Sw.: stipite rhachique haud tomen- 
tosa aculeatis, pinnulis subtus haud glaucis, laciniis linearibus nee ob- 
longis, soris fere totis obtectis, basi indusii haud patereeformi remanenti, 
fronde coriacea ;—a C. medullari, Sw., diff. pinnulis haud lato-lanceolatis 
epaleaceis, laciniis acutis et aculeis stipitis et rhacheos haud luridis ;— 
a C. crenulata, Bl., diff. stipite et rhachi muriculatis, pinnulis lineari- 
oblongis, rhachi et costa glabris, laciniis ad apicem crenatis. 
Now I proceed to Alsophila, and I shall begin with the 4. contami- 
nans, Wall. From this species I distinguish five forms or varieties, 
some of which I in the first instance regarded as new species; but 
having found the intermediate links, I think it better not to augment - 
too much the new species. It will I think be necessary to give a 
new diagnosis of the species, that thereby may be included the said 
varieties also, I propose the following one :—Arborea, trunco medulla 
alba crassa pleno et stipitibus basi dense paleaceis cum rhachi primaria 
et secundariis valde armatis; frondibus 2—3-pinnatis subtus glaucis 
preter rhaches secundarias et costas supra tomentellas glabris; pinnis 
oblongis acutis, pinnulis oblongo-lanceolatis subulatis profunde pinna-
