 crowded, from the centre of the fronds upwards overlapping each other, 

 about five inches long, and ending in lengthy narrow apices.

 of Messrs. Veitch, of Exeter: it is much narrower. Mr. Sim's form is 

 very good: it is well crested, and exceeds two feet in length, and is 

 more crested than in Messrs. Veitch's form. The Eev. F. Mules has also 

 found a very tine form. I have received additional fronds from the 

 Rev. C. Padley, of Bulwell Hall, and the Rev. F. Mules, of Marwood.
