On old walls, and in the moist shady fissures of rocks. Ray as- 

 serts that it dies whenever it gets upon burnt bricks. 



Perennial. June — October. 



Root tufted, dark brown. Fronds several, three or four inches 

 high, of the colour and aspect of Rue leaves, each with a long- 

 ish slalk ; the upper part doubly pinnate, or rather twice ter- 

 nate, the middle branch only being alternately pinnate. Leaflets 

 stout, wedge-shaped, or partly rhomboid, stali<ed, spreading ho- 

 rizontally, or a little deflexed, the extremity abrupt, or round- 

 ed, im equally notched. Masses several, close together about 

 the middle of each leaflet, and at length confluent, covering the 

 whole of its under side. Cover pale, crenate. Capsules dark 

 brown. 



The variety /3, delineated by Plukenet, I have not seen. This, ac- 

 cording to Dillenius in Ray's Synopsis, is what Mr. Vernon ga- 

 thered at Wambrise orWarbrise (perhaps Wambridge); but he 

 justly suspects that Ray confounded with it some young plants 

 of our Cystea regia. See the remarks upon that species, p. 303.
