774 FERNS OF NORTH QUEENSLAND, 



D. TRUNCATA (Poir.) O. Ktze. 

 Creeklet at base of Bartle Frere; July, 1913. This is the only 

 spot at which I saw this fine fern during the whole of my trip. 



Subgen. Goniopteris. 

 D. UROPHYLLA (Wall.) C. Chr. 



By creek, Yungaburra; August, 1913. 



Domin records two forms of this magnificent fern, viz., f. sub- 

 integra and f. crenata (both from Harvey's Creek). The descrip- 

 tion of Polypodium uropliyllum in H.B., Synops., p. 314, is, "the 

 edge entire or very slightly lobed." My specimens (all taken from 

 one spot, though probably not all from one plant) show consider- 

 able variation in the nature of the leaf-margin ; in some pinnae, the 

 lower half is subentire and the upper crenate. 



D. PCECILOPHLEBIA (Hook.) C. Chr. 



Rocky Hill, Kuranda; also near Yungaburra, and on the banks 

 of Lake Barrine; July- August, 1913. 

 (?)yar. DENSA, var.nov. 



Textura densior; sori ma j ores; inferior pinnarum margo saepe 

 profunde incisa. 



This variety is set up with some doubt. The deeply incised 

 lower margins are very noticeable where they occur, and the much 

 denser consistency of the leaves is very marked. I place here my 

 own specimens, collected, I believe, at Lake Barrine, and also a 

 specimen of D. pcecilophlehia sent to me by Mr. F. M. Bailey; 

 collected on the Endeavour River by Miss Lovall. 



(?)D. HiLLii (Bak.) C. Chr. 

 A single frond, among my specimens of D. pcecilophlehia, 

 shows distinctly villose costae, and may possibly belong to D. Hillii, 

 a species w^hich I have never seen. The figure in Bailey's "Liths." 

 (149) is, as pointed out by Domin, that of a different species. D. 

 Hillii, according to H.B., Synops., p. 505, is "simply pinnate." 

 D. TRIPHYLLA (Sw.) C Chr.; Meniscium triphyllum Sw. 

 By creeklet, at base of Bartle Frere, aiid also in Palm scrub at 

 eastern end of the mountain, near railway line; July, 1913. Mr.
