POLYSTICHUM AXGTJLARE. 189 



gQ.—Multifiihim, p. 89. MuUicristatum, of Wollastou, 



another name for KitsonicB. 



97.— Miiltifoniie, p. 132. 98.— Mult ilobum, p. 121. The Eev. 



F. Mules, of Marwood, has sent some very fine fronds. 



99. — Obtmisshmm, p. 122. Found also at Littleham, in North Devon- 

 shire, by the Eev. C. Padley. This, although somewhat narrower, 

 approaches very near to Ohtiisissimum. 



100. — Ohtusum, p. 87. One of the Bisen-aium, section.

lOZ.—Oxu, p. 158. 104-.—Oxijphyllum, p. 116. This 



Fern to me is quite distinct from Mtdf ilobum. The fronds I have 

 received are much more acute in the lobes, the pinnae and pinnules 

 more sharply pointed, and the inferior pinnules above twice the length 

 of the superior ones, the pinnules resembling branches, with distant 

 and stalked lobes. Pinnae bending upwards. Densely scaly. Length 

 two feet, width eight inches and a half. 



Padleijense. A foi-m of Proliferum.

107.— Phylloideum, p. 139. 108.— Plenum, p. 165. 



Plumoso-gracile, of Moore, another name for Incisum. 



109. — Plumosum, p. 113. The late Mr. Jackson's form is closer in 

 pinnae than that of Mr. WoUaston's. The pinnae overlapping, sub-opposite 

 below, alternate above, about thirty-five pairs of pinnae, the basal pair 

 much the largest, and inclined downwards. The pinnules on the lower 

 side of the pinnae twice the length of those on the upper side. In 

 fronds received from the Eev. C. Padley, of BulweU Hall, the lowest 

 pinnae are not larger, and are not inclined downwards. 



110. — Polydados, p. 145. 111. — Polydactylum, p. 114. Messrs. 



Stansfield, of Todmorden, have sent me a variety that is apparently 

 different; the frond is broader, the pinnae larger, and the pinnules near 

 the rachis exceedingly small, not so large as the auricles of the larger 

 pinnules, occasionally linear, long, narrow, and strongly auricled, and 

 distinctly stalked. About eleven pairs of pinnae, besides the apical 

 portion. 



112. — Polydadylum-comutum, p. 115. 



113. — Polueides, p. 141. * 114. — Pnemorsiim, p. 88. The Eev. 



C. Padley has found in Devonshire a form of this Fern, with fronds 

 from twenty to twenty-two inches long, and five inches and a half 

 wide, except the upper half, which gradually becomes narrower. Pinnae 

 opposite and sub-opposite below, alternate above. Somewhat similar to 

 the Irish form, except that the frond is not altered or praemorse, except 

 near the apex. Mr. Elworthy has sent me a form found near Nettle- 

 combe, formerly called Ahnijptum, (a variety not sufficiently distinct from 

 Prcemorsum.) Length fourteen inches, width very narrow, only two 

 inches and a half in the widest part. Pinnas more or less abrupt; 

 pinnules remote, very various in size and shape, more or less laciniated 

 or depauperated; the two or three basal pairs of pinnules smaller than
