divided, with, concave pinnae and strongly convex 
pinnules ; it is also somewhat glandular. 
L. aljoina is remarkable for being more delicate and 
membranaceous than other forms of the species ; the 
fronds normally oblong, or straigbtsided, with the 
point tapering off as in the typical spinulosa , but in 
some specimens even broadly ovate, almost or quite 
tripinnate below, bipinnate upwards. Found by Mr. 
Clowes at Hawes Water.
