EKizome horizontal, thin, shortly creeping. Eronds 12 to 18 

 inches long, usually ovate-lanceolate in the small form, but more 

 triangular-ovate in the larger, in outline, the stipes long, slender, 

 sulcate and densely covered at or near the base with dark brown 

 ovate acuminate scales, bitripinnate, the pinnae and lower pinnules 

 much elongated at the apex, the upper surface glossy, rhachis 

 and costules hairy. Yeins pinnate ending beyond the margin in 

 aculeate teeth. Sori medial. Eound abundant in the Brisbane 

 Eiver scrubs, and at once detected by the shining upper surface 

 of the fronds. This beautiful fern has been for a long time 

 confused with Lastrea acuminata, T. Moore, Aspidium acuminatum, 

 Hort., Aug., but from which it differs in the absence of indusia 

 and in the longer, more aculeate marginal teeth. 



Yar. tropica. This form has been thought to be identical with 

 the species called by Blume F. rufescens. It differs slightly from 

 F. aspidioides in wanting the gloss on the upper surface of frond, 

 is less divided, often wanting the marginal teeth, being more 

 crenulated on the obtuse pinnules, the close, soft, pubescence 

 having also a reddish tinge, these variations might in a great 

 measure be due to climate. Eanges, Trinity Bay Queensland.
