reniform indusium, and placed on the anterior branches of the 

 venules, forming one or two rows along the lobes ; spore-cases 

 brown. Side of a small brook, in the valley to the right of the 

 Paignton road, near the railway tunnel. Wood near Milber 

 Down. Woods at Lindridge. Berry Pomeroy woods. Grid- 

 leigh, near Chagford, etc. The variety dumetorum : " fronds 

 dwarf or dwarfish, oblong-ovate or triangular- ovate, bipinnate ; 

 stipes, rachides, and veins beneath clothed with glands ; pin-

4. liastrea semula (liay- scented^ or triangular pricJcly- 

 toothed Buckler- Fern.) "Fronds triangular or tria igular- ovate, 

 spreading, tripinnate, pinnules concave ; pinuulets pinnatifid ; 

 the mucronately serrate lobes curved upwards ; scales of the 

 stipes concolorous, narrow-lanceolate, laciniate, or fimbriate, 

 contorted ; indusium margined with minute sessile glands " 

 (Moore's Handbook). (Aspidium spinulosum, var. 7, Hooker and 

 Arnott. Lastrea Foenisecii, Bab. Moore, Nat. Print. Ferns, t. 

 27. Sowerby, Ferns, t. 14.) I have never found this species 

 myself in South Devon, but Mr. Moore, in the list of habitats at 

 the end of his 'History of British Ferns' gives "Devil's Tor,

 Caudex stout and either upright or decumbent, scaly, giving off 

 hard, wiry, dark-coloured roots. Stipes about 1-third or 1-fourth 

 the length of the entire frond, purplish-red or green, covered, 

 especially below, with reddish-brown or very dark-coloured lan- 

 ceolate or linear scales, the rachis is also sprinkled with smaller 

 and narrower ones. The fronds frequently grow in the vase-like 

 arrangement of Lastrea Fiiix-mas, and vary in height from 1 to 

 5 feet, they also vary much in their division and form, sometimes
