sea, and 1050 feet above the town of Settle : and also on rooks called White 

 Scars, above Ingleton, on the left or north side of the valley." 



Lancashike. — It was found by the Kev. J. Smythes, near the top lock 

 of the Lancaster and Kendal canal. (See Phytol. i. 478). 



(SoMEESETSHiHE. — " I beg to inclose a frond of what I beUeve to be the 

 true Lastrea rigida. I found a single plant, bearing only four fronds, in 

 a somewhat bleak and exposed situation within a few nules of Bath. I 

 searched diligently for other plants, but without success." — Mr. J. E. Vize, 

 in Phytol. iv. 1101. " Observing in the last number of the ' Phytologist ' 

 that a solitary plant of Lastrea rigida had been found near Bath by Mr. J. 

 E. Vize, may I suggest the possibihty, if not the probability, that it had 

 been planted there by Potter, a well-known fern-collector, now dead, en 

 route to Cheddar for Polypodium calcareum ; having heard from his own 

 mouth that he did so vpith other plants, in order to save their extermina- 

 tion."— Mr. Q. B. WoUaston, in Phytol. iv. 1134). 



In Ieeland it has been found in one locality only, and that on a wall. 

 I am indebted to Mr. Lovett Darby for a specimen, accompanied by the 

 following note: — " I gathered this fern early in the present month (Septem- 

 ber), in the county Louth, at Townley HaU, the residence of Mr. Balfour. 

 It was grovring on a wall, buOt of clay-slate, and much over-hung with 

 trees ; T saw about thirty plants of it." — Mr. 0. L. Darby, Phytol. iv. 726. 



I have to acknowledge my obligation to all the botanists 

 mentioned above, for specimens from the various localities, 

 with the exception of that in Lancashire. 



The radicles are long, and the caudex large and tufted : the 

 stipes is unusually thick at the base, and very densely clothed 

 with large, pale red, concolorous scales, which are present, al- 

 though less abundant, throughout its entire length ; the pro- 

 portion of the stipes to the frond varies between a fourth and 

 a half : the frond is nearly erect, lanceolate, and pinnate : the 

 pinnules are more or less crowded ; those towards the base are 

 more distant than those in the middle and upper part of the 

 frond ; they are also sometimes shorter and somewhat triangu- 

 lar, but this character appears rather the exception than the rule, 

 for in the specimens so kindly and liberally supplied me, I find 

 by far the greater number have the first pair of pinnae fully as 

 long as either of the others : all the pinnae are pinnate : the
