LASTREA DILATATA. 



297 



Pinnules usually an inch in length, the posterior pinnules on 

 the basal pinna as much as an inch and three quarters, lanceolate- 

 ovate and acute. The basal ones stalked, above these decurrent, 

 then adnate, and towards the apex confluent. Pinnules pinnatifid 

 almost to the mid vein; lobes oblong, adnate, cut or dentate, all 

 the serratures terminating in a bristle-like point. Fructification 

 extending over the whole frond. Somewhat similar varieties 

 have been found in various places, which are all glandular, 

 yet have more or less difference from the original normal form. 

 I am indebted to Mr. F. Clowes, of Windermere, for fronds.

Texera, Moore. (Fig. 240.) — Found at Windermere by Mr. 

 F. Clowes. More nearly approaching fuscipes than any other 

 variety, yet more divided and more delicate. A very fine 

 glandular form. Frond two to three feet in length, thin, 

 delicate, ovate in form, and tripinnate. Pinnae broad, and 

 caudately acuminate. The posterior pinnules of the two basal 

 pinnae elongate oblong-acuminate, the remainder shorter. 

 Pinnulets sessile below, adnate above, often somewhat falcate, 

 having a tendency to the development of an auricle-like basal 

 anterior lobe, profoundly serrated with acute mucronate teeth. 

 Stipes pale chesnut in colour. Scales lanceolate and dark 

 coloured. Stipes copiously glandular, as well as the rachides 

 and veins underneath. My thanks are due to Mr. F. Clowes, 

 for fronds.
