POLYSTICHUM ANGULARE. 175 



THE FOLLOWING REQUIRE NO ILLUSTRATIONS. 



Incompletum. — A subtripinnate form of large size. Piniias 

 linear-lanceolate. Pinnules very irregular. The superior basal 

 pinnule longest, the lobes of it divided to the costa, the other 

 pinnules varying much in size and shape, all very strongly 

 lobed and biserrate, frequently flexuose and laciniate. Very 

 scaly. My thanks are due to Mr. Charles Elworthy, of Net- 

 tlecombe, for fronds. 



Decompositum-Elworthii, Lowe. — A most lovely form of 

 Decompositum, found near Nettlecombe by Mr. C. Elworthy. 

 Length above two feet, width six to seven inches. The pinnae 

 in lower half of frond opposite, in upper half alternate; they 

 commence quite at the base, lea\ang no stipes. Colour of 

 fronds vivid green. Pinnee and pinnules crowded, the latter 

 deeply cut, very hirsute, and the sori on every pinnule, even 

 to the basal pinnae. My thanks are due to Mr. Elworthy for 

 fronds. 



Pulchrum-irregulare, Sim, MSS. — A handsome variety 

 found near Nettlecombe by Mr. Charles Elworthy. Length of 

 frond above two feet, width from six to eight inches, the apex 

 ending abruptly and irregularly. Pinnae opposite on the lower 

 half and alternate on the upper half of the frond. Stipes 

 and rachis very stout and densely scaly, deeply fluted. Pinnae 

 long, narrow, and acuminate, five inches in length, except the 

 upper six inches, where from two inches to less than an inch, 

 the smaller pinnae almost as broad as the others. Pinnules 

 stalked almost to the apex of the pinnae; the lower ones some- 

 what larger than the superior ones, deeply cut, strongly auricled, 

 the auricle divided to the base, sharply dentate. The upper 

 pinnules not auriculate, and undivided. The fronds I have 

 seen of this variety are not sufficiently irregular to warrant 

 its name; it is, however, a very pretty form. My thanks are 

 due to Mr. Charles Elworthy, of Xcttlecombc, for fronds.
