Specimens have the pinnules really entire in the lower half. 

 Bentliam, in Fl Austr., vii., 710, says of A. Bebeccm, "secondary 

 pinnae undivided, entire or crenate-serrate," and on the same 

 page, "crenate or obtusely serrate." I would suggest that, for 

 the normal form, the description "supra medium crenatis " 

 (F.V.M.), or "supra medium leviter crenato-serratis " (Dom.), 

 should be changed to " supra medium vel ad basin plus rainusve 

 crenatis vel crenato-serratis." The var. lobulata would still be 

 retained. 



Var. LOBULATA Dom. 



Herberton district; R. F. Waller, 1908 (Syd. Herb.). 



Two pimifP, in Mr. Waller's collection, correspond, the one 

 exactly, and the other approximately, to this variety. One of 

 these fronds is even more lobed than Mr. Bailey's specimens. In 

 some of the pinnules, the lobe-divisions reach to the rhachis, 

 forming distinct pinnulse. 



A. Baileyana Dom.; A. Rebeccce var. commutata Bail., 3rd Suppl. 

 Q. FL, 1890; Liths , P1.33. 

 Mr. Bailey calls this the "Wig Fern," and says, that the long 

 hair-like scales and the metamorphosed lower pinnse " crown the 

 stem with a wig-like growth." Domin compares these veinless 

 growths with the " Adventivblatter " of Hemitelia capensis, 

 figured by Dr. Christ, in Farnkr., p. 322, fig. 1023. These wig- 

 like pinnae are so distinctive that, though the ordinary pinnae 

 resemble those of A. Rebeccce so closely that Mr. Bailey might 

 well regard this fern as a variety of it, I think Domin is right 

 in making it a new species. The pinnules are wider and longer 

 than those of A. Rebeccce, and^ for the most part, a free vein stands 

 between the branched veins throughout. This fern I did not 

 collect, l)ut there is a specimen in the Syd. Herb., collected by 

 Waller, in the Herberton district— a mere scrap. 



A. CooPERi Hook. 



Street's Gully, Kuranda; July, 1913. 



A.excelsa, A. Cooperi, and A. australis have given considerable 

 trouble to botanists, lari^ely owing to the inadequacy of the 

 material in Herbaria. Tlie pinnules alone are quite insufficient.
