760 FERNS OP NORTH QUEENSLAND^ 



lobulas breves divisis, apicibus rotundatis; nervus validus, pinna- 

 tus; venulse dichotome ramosse, infra apicem evanidse; venulae 

 spuriae numerosae, breves, flexuosse, inter nervos irregulariter 

 dispersse, non marginales ; cellulse irregulariter sexangulares, 

 muris crassis, levibus. Sori in lobulis terminalibus immersi. 

 Imlusium infundibuliforme, vix dilatatum, vix hilabiatum. Re- 

 ceptaculum breviter exsertum. 



Falls, near Major's Selection, Ravenshoe, Herberton district;

The very distinct spurious venules make it doubtful whether 

 this plant is a true Gonocormus, but I place it here tentatively. 



The other species of this section recorded for North Queens- 

 land are T. digitatum Sw.,(Bellenden Ker; Domin); T. nanum 

 V.d.B.,(7^. Kurzii Bedd.) var. australiense Bail.; and T. WiJdii 

 Bail.,(nr. Cairns; C. J. Wild). These T did not find. Christen- 

 sen, in Index Fil., regards T. Wildii as a doubtful species, and 

 Bailey described it with some hesitancy; but it is a good species. 

 It should, perhaps, be described as " pinnatifid," rather than 

 "pinnate," though the lowest segments are sometimes pinnate. 

 The striking characters are the large indusium occupying, 

 upwards, almost the whole segment, with a wide but not two- 

 lipped mouth, and the uninterrupted border of two lines of 

 elongated cells, the inner denser so as to make, apparently, an 

 intramarginal spurious vein, the outer not so long, as a rule, and 

 hyaline. The cell-formation is open, and reminds of that of T. 

 nanum var. australiense, but the cells are larger. In 2\ nanum 

 also, there is a distinctly thickened submarginal line, and the 

 hyaline cells of the border are short, with thick walls at righc 

 angles to the edge, while in T. Wildii the hyaline cells are 

 longer and have thinner walls that, for the most part, are slant- 

 ing (Plate Ixxxvi., fig.4,a-c).

T. Barnardianum Bail. 



Frenchman's Creek; July, 1913. 



This species was also found in the Evelyn Scrub by Mr. R. F. 

 Waller, in 1908 (Hb. Syd.). It would appear to be fairly
