to the other: the present however is much the smaller plant, the sterile pinnules 

 are shortly petiolate, free and distinct, not confluent with the adjacent ones, en- 

 tire or nearly so. The terminal pinnae never become so remarkably elongated as 

 in the Pt. crenata (for which Loureiro's name of " PL caudata " is a very appro- 

 priate one), and we do not tind that gradual change from the sterile into a fertile 

 frond that is common iu Pi. crenata. Perhaps, though a very minute character, 

 that which distinguishes this species the most certainly from Pt. crenata is the 

 slender cartilaginous margin of the sterile pinnules. This structure does not 

 exist at all in Pt. Cretica, nor do the pinna?, in our present species, show any dis- 

 position to become confluent. In the fertile fronds, too, the pinnules are not only 

 sessile, but decurrent for a short way upon the rachis. 



I think I am correct in referring Mr. Reward's Pt. concinna to Pt. mutilata, 

 as a more compound state or variety. Mr. Smith's specimens, all that I have 

 seen, are only fertile fronds. 



12. Pt. (Eupteris) Hookeriana, Ag. ; " frond pinnate, pinnae 

 on each side 5-6, upper ones sessile, 2-3 of tlie inferior ones 

 petiolulate, sterile ones serrated, stipes smooth stramineous 

 trisulcate," Ag. — Ag. Sp. Pterid. p. 12. 



Hah. Ceylon, Emerson, Mrs. General Walker, Gardner, n. 1242. — " Species," 

 says Agardh, " ut crediderim, bene distincta, inter antecedentes simpliciores se- 

 quentesque pinnulatas, quasi intermedia. Ab antecedente," Pt. multiaurita, Ag., 

 which I consider simply a much developed form of Pt. Cretica, " substantia cori- 

 acea, piimis paucioribus attamen magis divisa, earumque forma facile distinguitur." 

 Specimens in our Herbarium, which are the authority for this species, differ in 

 no essential particulars from Pt. Cretica. 



13. Pt. (Eupteris) scabripes. Wall.; "frond pinnate, pinnae 

 on each side 2-3 sessile, uppermost ones decurrenti-confluent, 

 lowest bi- or tri-partite, sterile ones lanceolate serrate, fertile 

 ones linear-ensiform, veins once forked, stipes scabrous black- 

 purpHsh," Ag.— Wall. Cat. n. 9. Ag. Sp. Pterid. p. 11. 



Hab. Mountains of Penang, Wallich. — This again, I fear, is only a variety of 

 Pt. Cretica, with dark-coloured scabrous stipes, yet the careful Agardh held it to 

 be distinct. 



14. Pt. (Eupteris) ^n'om^is ; "fronds pinnate unequally bi- 

 partite at the base sometimes pinnatifid, rachis pale striated 

 glabrous, frondules shortly petiolate rather obtuse rounded at 

 the base entire, sterile ones linear-lanceolate acuminate ser- 

 rated above with unequal teeth crenate below the base entire, 

 nervelets bifurcate slender not reaching to the margin, fertile 

 ones linear crenate towards the sterile apex, rhizome aljout as 

 thick as a swan's quill, sporothecia narrow, indusia thin mem- 

 branaceous, sporangia ovate, annulus of twenty joints, spores 

 thick trigonous, sporangiastra intestiniform torulose con- 

 torted and whitish," Fee, Gen. Fit. p. 127-
