25. A. ( Pol ysti chum) microphyllum, Bl. ; "frond bipin- 

 nate coriaceous slightly hairy beneath, pinnules trapezoid 

 mucronate mucronately serrulate, lowest ones auricled at the 

 base above (auricles rotundato-mucronate), sori scattered, 

 rachis and stipes paleaceous." BL En. Fil. Jav. p. 163. —

Hab. Java, Blume, Zoll'mger, n. 408 z.— Blume's character is much too hrief 

 for any practical use. Kunze says, " e grege A. vesliti" a plant which we refer 

 to A. (Polyst.) aculeatiun. — May not the East Indian A. tacticopterum, Kze. 1. c, 

 be the same .' or some form of aculeatum ? Again, of his A. amblyotus, from Java, 

 Kunze says, " praecedenti (^A. microphyllo) affine ; sed pinnulis basi lobatis, medio 

 et apice acute serratis diversum et multo majus." It is a hopeless task to deter- 

 mine them without access to authentic specimens or faithful figures. 



26. A. (Polystichum) obtiisum, Mett. ; caudexa short thick 

 scaly rhizome, stipites 4-5 inches long squarrose with cojii- 

 ous ferruginous ovate very long pointed soft scales mixed with 

 narrow subulate ones which continue up the rachis, fronds a 

 span to nearly a foot long coriaceo-membranaceous slightly 

 villous above ferrugineo-hirsute beneath oblong bipinnate, the 

 apex long gradually acuminated, inferior pinnae 2-3 inches long 

 linear obtuse, their pinnules ^ of an inch long obovato-rhom- 

 boid very obliquely cuneate at the base, superior margin and 

 apex chiefly spinuloso-serrulate, superior pinnae oblong- 

 rhomboid obliquely cuneate at the base, auricled above, veins 

 forked close indistinct, involucres fringed at the margin.

Hab. Luzon, Cuming, n. 234, Thos. Lohb. — Mr. J. Smith speaks of this as a 

 doubtful species. My specimens are very uniform. Thomas Lohb has found the 

 same plant in the same island. It is remarkable in the lower half or rather 

 more being bipinnate, the rest pinnate. Mr. J. Smith does not say to which spe- 

 cies of the genus the present is most allied ; I should say it cannot be far re- 

 moved from some of the protean forms of Aspid. aculeatum. 



27. A. (Polystichum) ocidatum, Hook, (not Wall.); caudex ? 

 stipes a span long rather stout stramineous flexuose paleace- 

 ous with rather large rigid subulato-lanceolate black pale- 

 margined scales, these scales are continued on the rachises 

 but are smaller less deeply coloured and are mixed with
