800 NOTES FKOM THK BOTANIC GARDENS, SYDNEY, NO. XVI., 



inch broad, lanceolate in outline, cut down nearly to the rhachis^ 

 into erecto-patent entire or indi-stinctly lobulate blunt lobes with 

 slightly recurved margins, the lower shortened gradually into the 

 undulately winged short stipes, the upper ones shortened into an 

 undulately lobed blunt point. Veinlets simple or forked, con- 

 cealed amidst the almost herbaceous texture. Sori orbicular, 

 superficial or very slightly sunk into the tissue, comparatively 

 large, 3 or 4 on the longest lobes, solitary on the short ones. 



Filix parva, pallide virens, glaber prseter squanias lineari-lan- 

 ceolatas basi stipitis brevissimi. Froudibus lanceolatis 1-2" longis 

 et circiter I" latis, pinnatisectis fere ad rhachem in lobis lineari- 

 obtusis, marginibus leviter recurvatis; lobis inferioribus in rhachi 

 undulate alato contractis, lobis superioribus in apice undulato 

 contractis. Venis simplicibus in textura fere herbacea occultis; 

 soris orbicularibus, superficiariis, 3 v. 4 in lobis brevibus. 



This interesting small fern is so closely allied to Polypoduirn 

 sarmeiitosani Brackr., from the Sandwich Islands, that it may 

 perhaps be looked upon by some as a small form of it, but the 

 union would be rather forced. Besides the great difference in 

 size, the Queenslan<l fern difFeis from it in the very short stipes, 

 in the more herbaceous texture, in the slightly less deeply cut- 

 down lobes, and in the recurved margins of the lobes. Its posi- 

 tion in the Australian flora is next to P. blechnoides Hook., and.

This fern was originally described by C. B. Presl, in the 

 year 1836, in his " Tentainen Pteridographice," but it has since 

 been united with A. uidlaterale Lam., (.4. resectum Smith, in 

 Hooker & Baker's " Synopsis Filicum "). The Queensland fern 

 is so very distinct from A. unilaterale, that we are unable to 

 follow C. Christensen and Aldervelt van Rosenburgh in uniting 

 the two species; but ratiier follow R. Schlechter, who keeps A. 

 amcenum as a distinct .species in his " Beitrage zur Kenntniss der
