POLYSTICHUM ANGULARE. 



the superior basal pinnule, is conspicuous on the second, and 

 then gradually becomes indistinct and ceases. There is no 

 difference in the size of the basal pinnules in the lower portion 

 of the frond, but they increase in size from the centre of the 

 frond upwards. The edges of the pinnules are minutely ser- 

 rated; they are devoid of spines, except a solitary one at the 

 rounded apex, and also at the apex of the auricle. The upper 

 third of the frond differs considerably, the pinnules being much 

 smaller and narrower as they approach the apex, at length 

 becoming linear. The apex of the frond is an axact Linearc. 

 My thanks are due to the Rev. C. Padley for fronds. Illus- 

 tration a basal pinna, and an apical pinna.

Multiforme, WoUaston. (Fig. 108.) — This veiy pretty 

 variety was found in Devonshire, by Mr. G. B. Wollaston, of 

 Chiselhurst. The frond is natural in outline; the pinnae also 

 natural, but irregularly notched. The pinnules, however, are 

 of every conceivable shape, from a simple vein to a pinnule of 

 an inch and a half in length, pinnate, the pinnulets being 

 distinctly stalked.
