36 ON A NEW SPECIES OF FERN, I have taken no notice of such weeds as Polygonum aviculare, L. ; Erigcron canadensis, L. ; and E. Mnifolms, some species of Apium, Altemantliera, &c, as my object lias rather been to point out those naturalized plants which especially distinguish the colony. It will doubtless be a matter of suprise that, in a colony like Queensland, where so much cultivation is carried on, and in such an extensive range of plants, more than the above are not naturalized amongst us. On a new species of Fern, Asplenium Prenticei. By F. M. Bailey, Esq., F.L.S., Hon. Mem. Linn. Soc. N.S.W. I beg to bring before the Society and thus to introduce to science a species of Asplenium which I do not think has ever been previously described. I was so fortunate as to discover it in one of the deep umbrageous gullies of Trinity Bay Range, whose tropical richness will no doubt yield many other botanical novelties when fully explored. I saw it first when collecting in April 1877, and I then regarded it as a peculiar variety of A. decussation, Swartz. I find however, when I had leisure for a more careful examination and comparison, that the species belongs rather to the section Euasplenium than the section Diplasium, to which, had I been right in my first determination it should have been referred. In company with this species were some fine specimens of the noble A. laser ipitiifolium, Lam., and close to the rocks beside it was the small hairy-fronded Poh/podium Hookeri, Baker, and AnthropJvyum reticidatum, Kaulf., with plantain-like leaves. In the same gully the stately fern Aspidium confluens, Mettenius, was also very abundant, and the edge of the running streams was fringed with Trichomanes rigidum, Swartz. I may here remark that I have never found this latter fern in perfection except where its roots were washed with running water. It was on the trunk of the trees in this locality that I first noticed
