species, bul tlie descriptiou of Blume is too short to be satisfactory ; though 

 1 liave followed Mr. J. Smith in considering^ our plant the same. The 

 main racliis is of a rich chestnut brown color; the principal pinnules have 

 a distinct petiole, a line or a line and a half long: the texture is coriace- 

 ous, the surl'ace singularly glossy, with the veins having the same appear- 

 ance as to color and surface as" tlie frond. Fructifications dark brown, 

 sometimes occupying the greater part of the pinnule, which is then con- 

 tracted, or confined to the lower segments, when they become contracted so 

 that the broadest part is above the middle. A few minute dark brown bul- 

 late scales are seen on the costa. Veins simple. 



48. A. contaminans. Wall.; aculeolate, frond bipimiate co- 

 riaceous glaticous beneath, pinnules oblong-lanceolate acu- 

 minate decjily pinnatifid, segments oblong falcate the fertile 

 ones narrower rather obtuse crentilate, sori upon forked veins 

 in lines parallel with the costa and covering nearly the whole 

 segment, capsules mixed with hairs. (Tab. XVIII. B.) A.

 Cuming, n. 71 . South Camarines, Cumhiff, n. 291. — i3. Isle Negros, Phi- 

 lippine Islands, Cuming, n. 345. — A well marked species, with rather rigid 

 coriaceous fronds, becoming very dark colored in drying, but always retain- 

 ing their glaucous hue beneath. The stipes is muricated with very short 

 sharp points, and the same extend to the main raohis and to that of the 

 pinnae, in this respect resembling the A. c.vcelsa. I retain the name of its 

 iirst discoverer, Dr. Wallich, by whom it has been extensively distributed. 

 Blume thinks it probable it may be the Cyathea glauca of Bory. 



49. A. cauclata, J. Sm.; unarmed, frond bipinnate glabrous, 

 pinnules sessile oblong-lanceolate broadest at the base the 

 apex suddenly contracted into a long narrow serrated tail-like 

 acumen coriaceo-membranaceous paler and slightly glaucous 

 beneath, the segments oblong a little falcate rather obtuse ser- 

 rated, veins simple or more generally forked, bullate scales 

 none, sori close to the midrib, occupying the lower part of 

 the segments. (Tab. XX. B.) J. Sm. in En. Fil. Philipp. 

 {name oihj). 



Hab. Manilla, Lugon, Cuming, n.2G7. — The most marked character 

 about this plant is the sudden contraction of its pinnule into a long tail- 

 like point. The general form of the pinnules and segments approaches 

 those of Ah. contaminans, but the under surface is scarcely glaucous. Mr. 

 .1. Smith thinks this species may not be different from A. lunulata, our 

 n. 44. 



50. A. Brunoniana, Wall. ; unarmed, fronds bipinnate 

 pinnules lanceolate acuminate deeply pinnatifid coriaceous 

 glaucous beneath, veins once or twice forked, bullate scales 

 none, margin recurved entire or crenulate, sori in two rows
