 hairy, hairs ferruginous. Fronds stipitate, ovate to cimeate, the margins even 

 repand or lobed, 4 to 6 lines long. Veins pinnately costseform, between these are

 Receptacle slightly exserted.— Syn. Ql. Fl. 686 ; Bail. Litho. Ferns Ql. 21.

 very short or wanting, the lamina tapering to the base. Costa prominent, the 

 lateral veins simple or forked, joining at the margin into a vein and marginal
