764 FERNS OF NORTH QUEENSLAND, 



fication. I take the broadest view of the two subgenera (seeing 

 it is convenient to follow the accepted classification), as does 

 Sadebeck, and divide the species as follows: 



Ultimate segments entire Euhymenophyllum. 



Ultimate segments serrate or denticulate.. Leptocionium. 



Subgenus i. EuhymenophylluTn. 



Section i. Receptacle not exserted. 



H. AUSTRALE Willd.; H. javanicvm Spreng. 



Evelyn Scrub, mixed with H. Shirley annm Dom.; R. F, Waller, 

 1908 (Hb. Syd.). 



The fronds are considerably larger than any I have seen from 

 New South Wales, though not larger than specimens from the 

 Islands. 

 H. Walleri Maiden & Betche, Proc. Linn. Soc. N. S. Wales, 

 1910, p.802. 



On prostrate tree by creek, Major's Homestead, Ravenshoe, 

 Herberton district; August, 1913. 



My specimens are smaller and mostly more orbicular than 

 those of the type (Evelyn Scrub; Waller). They were growing 

 in association with H. Baileyanum, both species in rather poor 

 condition. 



At first, I intended publishing this plant as a new species, but 

 I am convinced that it is only a small form of H. Walleri. The 

 description of that species will, however, need some slight modi- 

 fication in the light of the additional specimens The fronds are 

 described as " 1^ long and 1" broad, sometimes narrower in the 

 sterile fronds." My specimens range from 1-2 cm. long and 

 broad {i.e., not more than 2/3" in greatest length), though they 

 are sometimes, like the type, a little longer than broad. The 

 overlapping pinnae (in both collections) are very marked; when 

 moist, the pinnules and lobes stand up from the plane of the 

 frond, after the manner of the lobes of a parsley leaf. It should 

 also be noted that scales, similar to those of the rhizome and 

 stipes, are found on the rhachis and costse, and often fringing 

 the base of the indusium. Perhaps it may be allowable to regard 

 my specimens as var. oi'hiculatum, var.nov.
