DESCRIPTIONS OF THE SPECIES 
177 
separate, roundish, flabellate, one-sided, decurrent, sub-opposite, 
toothed pinnules, clothed on the under side with reddish linear 
scales; upper side glabrous. Veins free. 
Pappe and Rawson describe this as annual, but that 
applies to the fronds only, not to the plant.

The var. bipinnata of our first edition is now separated as 
Notholaena bipinnata. 
Genus 21. Blechnum Linn. 
Fronds dimorphous, the fertile pinnae usually narrower 
than the barren. Sori linear, parallel with the mid-rib and 
intramarginal, or occupying the whole under surface of the 
fertile pinnae (variable in some species). Indusium present, 
opening toward the mid-rib. A very natural genus in which 
most of the species agree in habit, having dimorphous fronds, 
and sub-erect rhizomes, or erect caudices. One of our species, 
B. punctulatum , sometimes adheres to the above generic 
character, but the sori vary, and forms of it occur answering 
to Blechnum, Asplenium, and Scolopendrium. B. australe 
also varies very considerably. 
As now constituted, Blechnum includes both Blechnum 
and Lomaria of our first edition, which are now looked upon 
s. f. s. A.
