Var. glandulosa, Newm. A very glandular plant is found 

 agreeing in most particulars with this variety. Rhizome de- 

 cumbent. Fronds upwards of 2 ft. high, oblong-lanceolate ; the 

 lowest pinnae are twisted into nearly a horizontal plane, pointing 

 forward, forming an acute angle with the rachis. Stipes, rachis, 

 and under surface of the frond, densely covered with stalked 

 glands ; scales dark in the centre ; lowest pinnae broad and 

 unequally deltoid, pinnules ovate -lanceolate, pinnatifid almost to

 acuminate, lowest unequal-sided, the next nearly equal. Pinnules 

 somewhat convex, basal ones stalked, next decurrent. Sori 

 small, nearer the midrib than margin. Indusia with stalked
