794 FERNS OF NORTH QUEENSLAND^ 



Judging from the descriptions in A. van Rosenburgh (Malayan 

 Ferns, p. 607), allied to P. stetiobasis Bak., (from Sumatra), and 

 P. craterisorum Harr., (from the Philippines) ; but sufficiently 

 differing from both. The crater-like receptacles of the sori, with 

 their more or less setaceous edges, are very marked. It differs 

 greatly from P. fusco-pilosum, of which Mr. Bailey kindly sent 

 me typical specimens. 



Subgen. Goniophlehium. 

 P. VERRUCOSUM Wall. 

 Babinda and Frenchman's Creek; July, 1913. 

 P. SUBAURICULATUM Bl., with(?)var. serrati folium {Brack.) Hook. 



Very frequent throughout the Cairns district, on trees or rocks. 

 Good specimens from Ravenshoe, mostly epiphytic on trees. 



Domin (Prodr., p. 172) holds that many of the Australian 

 specimens determined as P. suhauriculatum belong to the var. ser- 

 rati folium. My own numerous specimens vary considerably in the 

 nature of their serration, but are, all, more or less serrate. A 

 van Rosenburgh (Malayan Ferns, pp. 662-3), says, of P. suhauri- 

 culatum, "the edge entire, slightly crenate, or faintly toothed;" 

 and, of the var. serratifolium, "Pinnae coarsely toothed" ; Hooker 

 (Sp. Fil. v., p. 33) says, of this species, "serrated." H.B. (Syn. 

 p. 344) describe the species as herbaceous or subcoriaceous, "the 

 edge entire or slightly toothed," and the var. as "deeply toothed 

 herbaceous form." Hooker, in Sp. Fil. {loc. cit.) cites Blume's 

 figure of P. suhauriculatum (Fl. Jav., ii., t. 83) as "very good"; 

 and Blume's figure is distinctly serrated, though not, or scarcely, 

 auriculate. Bailey's figure (Liths., 162), which Domin considers 

 to be "certainly" var. serratifolium, shows stronger serrations 

 than Blume's figure, but very distinctive auricles. Beddome, in 

 Ferns of Brit. Ind. i., t. 78, figures P. suhauriculatum with strong 

 serrations, though the pinnae are scarcely typical; his description 

 is "serrated." The name "serratifolium^' certainly seems to be 

 misplaced, even if the variety itself should be recognised. Blume, 

 in Fil. Jav. p. 177) makes no mention of an entire pinna, but 

 simply says "serrulatae," the accompanying figure, as stated above, 

 is serrated somewhat strongly.
