768 FERNS OF NORTH QUEENSLAND,, 



superiore. Indusium breviter obconicum, tubo brevi, striis 

 paucis (2 vel 3) prsedito, labiis magnis, duas partes tertias ex 

 indusio occupantibus, apice rotundato, sinuato-denticulato ad 

 sinuato-subfimbriato. Receptaculurti validum, exsertum. Sporae 

 mediocres, leves, flavae. 



Frencliman's Creek; July, 1913. On rocks. 



In the absence of specimens of H. Neesii and the allied Bos- 

 chian species, this new species is set up with some hesitancy. 

 None of these allied plants have, however, so far as I can find, 

 been previously recorded for Australia, and the present plant 

 appears to differ sufficiently, (l)from H. Neesii by the sinuato- 

 denticulate wing of the stipes, the absence of the muricate denta- 

 tions on the indusium, etc.; (2) from H. aculeatum by the much 

 narrower wing of the rhachis; and (3) from other species by the 

 striking elongations that often mark the dentations of the wing 

 throughout. The fruiting specimens in my collection are few 

 and old, so that the description of the receptacle and the base of 

 the indusium is liable to correction. The few striae appear to 

 reach half-way up the indusium, and, in one or two specimens, 

 seem to end in a free seta.

 Domin (Prodr., pp. 28-29) distinguishes vars. normalis and 

 lobulata, the former, in accordance with the original description, 

 having the pinnules crenato-serrate in the upper Iialf only, and 

 the latter being lobulato-crenate down to the base. The var. 

 lobulata is set up for the specimen figured by Bailey in Liths., 

 PL 3 2 (collected on Bellenden Ker). I possess a frond of this 

 form, kindly sent to me by Mr, Bailey, under the name A. 

 Reheccce. Domin does not seem to have collected this variety, 

 nor did I, though but few of my specimens are, strictly speaking, 

 crenato-serrate in the upper half only. On many of the pinnae, 

 the loiver pinnules are almost entire below and serrate in the 

 upper half, while the higher pinnules are serrate throughout, the 

 terminal pinnule often conspicuously lobed. Very few of my
