 mens in my herharivim, justify me, I think, in bringing most of the above syno- 

 nyms and'locahties under the Aspid. terminans of Wallich, and certainly these 

 specimens have a pecuhar aspect, mainly arising from the sori being apicular, if I 

 may so say, confined to the rather short lobes of the pinnae, and often not ex- 

 tending so far down as to the sinus, but leaving a broad longitudinal disk, with 

 thecosla in the centre, quite free from sori. But, again, I have specimens -with 

 sori approaching the costa, and then the difficulty is to distinguish it from some 

 forms of \Yhat 1 have here called N. unituin. 



23. N. (Euneplirodium) Arbuscula, Desv. ; caudex creep- 

 ing, stipites approximate a span to a foot or more long, fronds 

 firm-membranaceous scarcely subcoriaceous pubescent 1-2 

 feet long a span broad oblong-lanceolate acuminate a good 

 deal yet abruptly attenuated at the base, pinnated, pinnee ap- 

 proximate subpetiolate from a dilated base frequently auricled 

 above and rotundate below narrow-oblong gradually and 

 finely acuminated coarsely crenato-serrate, lower ones (several 

 pairs) dwarfed remote subdeltoid and subtrilobed, three or 

 four pairs of the veinlets anastomosing, a few free veinlets only 

 in the teeth, sori solitary near the middle of each veinlet ex- 

 cept on the teeth, indusium small rotundato-reniform. — Aspi-

 Dr. Wallich's Aspid.*Hookeri (figured in the ' Icones Flantarum ') does not differ 

 from it ; and striking as are the dwarfed lower pinnules upon our specimens, we 

 know that in N. molle, and other Jspidiaceous species, they are not always con- 

 stant. 



24. N. (Eunephrodium) lineatum, Pr. ; "rhizome ascend- 

 ing, fronds dimorphous, sterile stipites 4-5 inches long 

 hairy above, fronds rigid, G\ inches to 1 foot long pubescent 

 at length nearly glabrous ovate or lanceolate pinnated, pinnas 

 five to eight pairs sessile 1-4 inches long -i of an inch 

 wide from a truncated base generally auricled above oblong 

 entire or serrated repando-serrate towards the apex which 

 is rather obtuse or shortly cuspidato-acuminate confluent 

 into a pinnatifid apex, or the lateral pinnae are 4 lines long
