localities from tlie coarser, drooping and very frequently re- 
curved L. dilatata. The peculiarity, mentioned by Mr. 
Newman, of the sori being confined to the upper part of the 
frond, certainly does not apply to the plants in this neigh- 
bourhood, as most of the larger, healthy, and well-grown 
plants have the sori distributed all over the backs of the 
frond. A variety occurs in Soothill Wood, with very con- 
tracted pinnules; in some instances, scarcely toothed and 
almost spineless. It dies off much earher than the usual 
form, thus standing brown and withered when all the other 
ferns in its vicinity are fresh and green. From some forms 
of the L. spinulosa that I possess from Emaresborough, I 
believe that this is the fern that was entered in Baines’ 
“ Flora of Yorkshire ” for Lastrea eristata.
