188 PTERIS. 



the Pt. biaurita of Swartz and Willdenow, though not of Linnaeus, which is a 

 species having more or less anastomosing veins, but it is never the case vvith this. 

 Our figure in the ' Icones Filicum ' will show what is intended by this species. 



48. Pt. (Eupteris) Kingiana,^x\d\.; "frond pinnated, pin- 

 nae subpetiolate pinnatisect the lowest ones pinnulate, seg- 

 ments lanceolate-linear obtuse serrated decurrenti-subappen- 

 diculate, veins forked basal inferior one arising from the main 

 costa bifurcate, stipes and costa (the latter sometimes stra- 

 mineous) black-purple glossy /M//. — Engl. Prodr. Fl. Norfolk, 

 "p. 13. Ag. Sp. Gen. Pterid. p. 34. 



Ilab. Moist shady places, Norfolk Island, All. Cunninffham, C. J. Simmom, 

 Esq., Dr. V. Thomson, Milne, in TJenJianis Surveying Voyage, " Species, ut credi- 

 derim certe distincta, at characteribus dilficilius circumscribenda. Frons tota 

 atro-virescens, costis discoloribus variegata, inter pulcbriores totius generis." — I 

 can agree with most of the above observations of Agardb ; yet were it not for the 

 high authority of Endlicher and Agardh, I should be disposed to consider it one of 

 the many forms of Pt. tremula, of which I have recently received specimens from 

 New Zealand that I can scarcely distinguish from what Agardh has considered 

 and marked as Pt. Kingiana, from Norfolk Island. Agardh is of opinion that 

 this is the South African Pt. elegans of Jacquin, which Kunze, with more justice, 

 perhaps, refers to Pt. flabellata. (See our notes on the affinity of Pt. tremula, 

 p. 175, with Pt. arguta.) 



49. Pt. (Eupteris) Trattinickiana,^nd\. ; "frond membra- 

 naceous tripartite, branches pinnate, pinnae pinnatifid, seg- 

 ments oblong-linear obtuse distinct [discreta) sliarply serru- 

 late, veins forked, sori interrupted." — Endl. Prodr. Fl. Nor- 

 folk, p. 14. Ag. Sp. Gen. Pterid. p. 44, note. 



Ilab. Norfolk Island, Ferd. Bauer {Endl). " Kami pinnati laterales divari- 

 cato-patentes. Pinna; approximatim alternae, paribus 1^-2 pollicares dissitis, 4-5- 

 pollicares, usque ad costam pinnatifidae. Laciniae oblongo-lineares, erecto-paten- 

 tes obtusae, 9 lineas longae, 3 lineas latae, alternae, discretas, infima basi subpinna- 

 tifidae, omnes argute serrulatae. Indusia membranacea, interrupta, sa;pius unila- 

 teralia." — If tliis had been placed by Endlicher next to his Pt. Kingiana, I should 

 have thought it quite likely to be a state of that plant, passing into Pt. tremula, 

 and the venation is the same (§ Eupteris) ; but lie has placed his Pt. Zahlbruck- 

 neriana between the two, which is of the Litohrochia section. I am still disposed 

 to consider it may be such, as some of my New Zealand specimens of that very 

 variable plant Pt. tremula sufficiently correspond with it. 



50. Pt. (Eupteris) j9?/rop%//a,*Bl.; "frond pinnated, pinnae 

 petiolate subpinnatisect, lower ones auriculated the lowest 

 ones pinnulate, segments oblong linear obtuse entire equal 

 at the base, veins forked the ])asal ones arising from the axil 

 of the costule and terminating at the margin above the sinus, 

 stipes purplish-brown," Ag. — Bl. En. Fil. Jav. p. 212, Ag.
