148 ENGLISH BOTANY. 



EXCLUDED SPECIES. 

 ASPLENIUM REFRACTUM. Moore. 



A. fontanum, var. Milde, Fil. Europ. p. 70. 



A. ebeneum, Ait. Var. refractum, Lowe, Our Native Ferns, Vol. II. p. 169. 



" Fronds linear, subbipinnate. Pinnas short, oblong, obtuse, re- 

 fracted, pinnate at the base, pinnatifid above. Pinnules (the lowest 

 anterior one only distinct, the rest more or less confluent) roundish, 

 with a few coarse angular mucronate teeth, the upper two four- 

 toothed, the lower ones overlapping. Sori short, oblong-oblique, in 

 a line on each side near the costa of the pinnae. Raehis chestnut- 

 coloured, marginate above, not winged, bulbil-bearing." Moore, 

 'Nat. Print Brit. Ferns,' 8vo. ed. vol. ii. p. 66. 



This plant is known only in cultivation. First seen in 1851 by 

 Mr. T. Moore, from the gardens at Peper-Harrow Park, Surrey. 

 Afterwards exhibited by Mr. Parker, nurseryman, Hornsey. 



" These plants being reported by Mr. Williams, then of Hoddesdon, 

 to have been received by him a few years previously as A. viride, 

 from a gardener whose friend, named Filden, who it appears died soon 

 after the occurrence, had found them in Scotland and sent three 

 roots." — Moore. 



Judging from Mr. Moore's description and the figure in Lowe's 

 ' Native Ferns,' vol. ii. pi. xlii., I believe this to be a distinct species, 

 but the evidence that it occurred in Scotland is far too slight to 

 entitle it to a place in the ' British Flora.' 



LOMARIA ALPINA. Sprmg. 



A plant of the temperate parts of the Southern Hemisphere, which 

 was reported to have been found by a lady "in the crevices of an 

 old stone wall, by the side of a mountain torrent, not far from Loch 

 Tay, Perthshire, Scotland, June, 1856." Mr. Gr. B. Wollaston, in 

 ' Phytologist,' series ii. 1859, p. 157. Doubtless an error. 



ONOCLEA SENSIBILIS. Linn. 



A North American plant, which has escaped from cultivation or 

 been planted in a few localities. Seen by Mr. H. Baines "in a lane 

 at Moreby, near York, now extinct ?" Suppl. Fl. Yorksh. p. 144, and 

 Phytol. vol. i. p. 453. Also naturalised near Warrington, Lancashire ; 

 Mr. Borrer writes concerning it, " Onoclea sensibilis was thriving
