A VERY beautiful Fern apparently distinct from Lastrea 

 dilatata. This is one of the scented Ferns, the fronds giving 

 out a fragrance like newly-mown hay. 



The fronds, which are triangular-ovate, sometimes quite 

 triangular, are tripinnate, having concave pinnules, and on 

 this account it is sometimes called the "Concave Buckler 

 Fern." Scales of the stipes whole coloured, narrow lance-shaped 

 in form, and laciniate or fimbriate on the margin, frequently 

 contorted. The pinnulets are pinnatifid, the lobes mucronately 

 serrate, and curving upwards. 



The indusium has minute sessile glands on the margin. 



The caudex thick and copiously scaly. 



The stipes is usually about half the length of the whole 

 frond, rigid, somewhat stout, and purplish brown in colour. 

 Copiously scaly. 



Rachis greenish, and less scaly. 



Rachis, stipes, and secondary rachides bearing many small, 

 sessile, spherical glands. 



Fronds numerous. Height from twelve to twenty-four 

 inches, breadth from five to eight inches. Colour rich bright 

 green, paler beneath. Elongate-triangular, tripinnate, the 

 upper surface crispy. 



Pinnae opposite or subopposite. Broadly and unequally 

 deltoid. 



Pinnules in the anterior side less than those on the posterior 

 side. Profoundly pinnatifid, the lobes oblong and serrated. 



The basal pinnae, pinnules, and pinnulets stalked. 



The margins of the pinnules and lobes mucronately toothed, 

 the margins turning upwards from the drooping fronds so that 

 all the divisions are concave, giving the whole frond an elegant 

 crispy appearance. 



Fructification occupying the whole under surface of the frond.
