70 ENGLISH BOTANY. 



between Filix-mas and spinulosa ; and Mr. Clowes writes, " I have 

 no doubt that L. remota of Moore and Braun is a hybrid. It has 

 been sown over and over again, and always produced L. Filix-mas, 

 var. paleacea. I do not know whether L. dilatata or spinulosa has 

 ever come up from its spores ; but as the plant called L. remota has 

 never come from its spores, I cannot think it a species or variety. 

 I do not know whether it is a hybrid between L. Filix-mas and 

 L. dilatata or L. spinulosa." 



It appears to be a plant of extreme rarity, as only 3 stations are 

 known for it — namely, near the Cataract of Geroldsau, in the Grand 

 Duchy of Baden, where it was found growing with L. spinulosa and 

 Filix-mas by A. Braun in 1834 ; in the Aachener-Busch, between 

 Aix-la-Chapelle and Altenberg, found by Braun in 1859 ; and at 

 Windermere, in 1854, by Messrs. Huddart and Clowes, but it was not 

 recognised till sent to Mr. T. Moore in 1859. In 1870 the late Mr. 

 J. Ward sent to the Botanical Exchange Club some examples of a 

 Fern from the Black Plantation, near Richmond, Yorkshire, July 

 1870. The specimens were named by Mr. Ward 'L. dilatata, var.' 

 Mr. H. C. Watson named them ' spinulosa.' I was inclined to refer 

 them to Filix-mas, var. incisa. The specimens are almost barren, 

 and evidently malformed ; but, except for the shorter and broader 

 fronds (1^ to 2 feet by 5 to 8 inches), less acute teeth, and the 

 shorter stipes, they agree best with L. remota. It is to be hoped 

 that some botanist will examine the locality.
