CYSTOPTERIS ANGUSTATA. 107 
Scot. 678, to have been acquainted, like Mr. Dickson, with our 
Cystva ( Cystopteris) angustata under that name ; and he quotes 
Gerarde rightly, justly objecting to Plukenet's t. 179. f. 5. 
Lightfoot's description is excellent, though he submits, as I 
have formerly done, to Haller, Weis, and others, who con- 
sider it as a variety of our O. fragilis. The late Mr. Davall 
took it for Haller's n. 1705 ; but that plant, with many 
errors in the synonyms, is certainly Aspidium dilatalum. Our 
Cystea (Cystopteris) angustata may be w. 1708 of Haller, but 
his references are confused. Mr. Hudson, on seeing Mr. 
Davall's specimens of the Fern in question, declared it very 
different from his own Polypodium rhteticum, which indeed 
is Aspidlum dumetorum. I have little scruple in referring 
the obscure and long-disputed figure of Clusius, reprinted 
in Gerarde, as above quoted, to this Cystea (Cystopteris) 
angustata, though the draughtsman has omitted the ultimate 
divisions of the leaflets, well enough expressed by Hoff- 
mann and Villars. I have never received this Fern from 
Wales, but if it be not Ray's Polypodium ilvense, it is wanting 
in the Synopsis. The wooden cut of Dalechamp, copied in 
J. Bauhin, and quoted doubtingly by Ray, should rather 
seem to be the totally different Acrostic/turn Marantte, as 
Bauhin himself suspected." 
The cultivation required by this Feru is the same as 
for Cystopteris alpina, stated at page 102. It requires, 
however, more shade, and does well under the shadow 
of other plants in a cool greenhouse.
