ticum in the Sydney Herbarium (from the Philippines), which 

 have a long, un winged stipes, a different cell-formation, and 

 shorter rows of sori. Domin's var stenorhaceuin (from Allumbah 

 and Lake Eacham) does not seem to be represented in my 

 collection. 



P. Selliguea Mett., var. Sayeri (F.v.M.) Dom. ; Grammitis 

 memhranacea Bail.; Polypodiiim Baileyi C. Chr. 



Herberton district (Ravenshoe, etc.); August, 1913. 



In general appearance much like P. amplum, but the rows of 

 sori are shorter, and the cell-formation is different. It is common 

 in the scrubs on the Tableland, at Ravenshoe, but not in the 

 coastal scrubs. Domin (Prodr., pp. 184-7) gives a careful account 

 of its different forms. His var. normale has simple fronds; and 

 A. van Rosenburgh( Malayan Ferns, pp. 67 1-3) defines F. Selliguea 

 Mett., in that sense. The Queensland form, which has divided 

 fronds, must, therefore, be regarded as a var, {Sayeri). I did not 

 find the form with simple fronds. 



Cyclophorus Desv. 

 C, CONFLUENS (R.Br.) C. Chr. 

 Cairns district (Hoc); July- August, 1913. 



C. ACROSTiCHOiDES (Forst.) Presl. 



Throughout the Cairns district, but found in large quantities 

 on the northern side of the Barron River, at Kuranda; July- 

 August, 1913. 



Domin's notes on the genus Cyclophorus (Prodr., p. 187) are 

 very useful. He does not recognise C. serpens on the Australian 

 continent, except in the var. rupestris; and he sets up a new 

 species, C. spicatus. The structure of the scales on the rhizome 

 is an important factor in the determination of the species of this 

 interesting genus. 



Drynaria J. Sm. 

 D. RiGiDULA (Sw.) Bedd.; Polypodium Sw. 

 At many places throughout the Cairns-Herberton district. The 

 varieties Vidgeni and cristata, published by Mr. Bailey, are inter- 

 esting bushhouse plants.
