ATHYRIUM FILIX-FCEMINA. 



the pinnae tliemselves are either totally wanting, or have merely 

 their midribs present. The variety grows well in Mr. Clowes' 

 out-door Fernery at Windermere, and is quite constant to its 

 odd-looking peculiarities. The illustration is from a division 

 of the original plant, forwarded by Mr. C. Monkman. The 

 variety is more curious than pretty.

Acuminatum, Moore. (Fig. 286.) — Found some years ago 

 on Snowdon by Mr. W. Pamplin. This interesting and singular 

 variety is of dwarf habit. The fronds, which are broadly 

 lanceolate, are somewhat more than twelve inches in length. 

 The pinnae are crowded, brief, deflexed below, the longest 

 pinnae terminating in a serrated acuminate point. The pinnules 

 distinct, but decurrent, linear-oblong in form, blunt at the 

 apex, and frequently narrowed below, numerous, patent, {%. e. 

 spreading at an angle of 45°,) pinnatifid in the basal part. The 

 dentation of the pinnules and lobes also long and acute. Sori 

 in lines near the costa, and abundant. The chief peculiarity 

 of this slender and graceful variety consists in its acuminated 

 pinnae, and narrow oblong pinnules. 



PoLYCLADOS-iRREGULARE, Moore. — Found by Mr. G. B. Wol- 

 laston, of Chlselhurst, in Pett's Wood, near Chiselhurst, Kent, 

 and at Hulm, near Windermere. Fronds frequently branched, 

 and multifid at the apex; the apices also of the irregular 

 confused-looking pinnae frequently forked. Pinnules irregular 

 both in size and form, sometimes ovate and profoundly pinna- 

 tifid, occasionally linear, with narrow lobes, or distorted, or 

 abbreviated. Dentation not prominent, brief, and acute. It is 

 not necessary to give an illustration.
