BROAD PEICKLY-TOOTHED BUCKLER FEEN 57 



dwarfish, with broad-ovate or elongate-triangular and 

 sometimes deltoid fronds, remarkable for their glandular 

 surface, and for the large abundant sori produced 

 freely on plants of a very immature age. Some of 

 its modifications have been referred to var. collina, 

 from which, however, they differ in their abundant 

 glands and fimbriated or jagged scales. Miss Beever's 

 plant was found on the fells of Silverthwaite, West- 

 morland, and the same form has been gathered by Mr. 

 Clowes near Hawes Water, and by the Eev. Gr. Finder 

 near Elter Water. 



L. collina is another distinct and permanent variety, 

 a remarkably neat and elegant plant, growing erectly, 

 the frond having sometimes an ovate outline alternately 

 elongated at the apex, sometimes more elongated, ob- 

 long-lanceolate or ovate-lanceolate, dark green, a foot 

 to two feet high, smooth or sparingly glandular, bi- 

 pinnate. The stipes varies from one-half to one-third 

 of the frond, green above, tinged with dark purply- 

 brown at the base, with entire lanceolate dark-brown 

 scales, conspicuously darker in the centre. The scales 

 narrow, with a long subnate point, at the base of the 

 stipes, where they are' most numerous, broader and 

 shorter higher up ; the rachis almost without. The 

 pinnse, especially the lower, distant and spreading, the 

 lowest pair unequally deltoid, the next more elongate 

 and less unequal, the rest narrower, parallel-sided, 

 rounding slightly near the end to an acutish point, not 

 acuminate. Pinnules convex, obtusely oblong-ovate, 

 the basal narrowed to a broadish stalk-like attachment, 

 the rest sessile and more or less decurrent ; the larger
