POLYSTICHUM ACULEATUM, var. ACROCLADON (Lowe) 
Mrs. Agar Thompson. S. Devon. 1858. 
1209-1117 
By Mr. Wollaston. The only densely-crested form of aculeatum 
—and perhaps it is chiefly from this cause that some have doubted 
whether it belongs to this species. Mr. Padley, who has had 
more opportunity of observing this plant than anyone else, and 
has brought to bear on these matters as large an experience and 
as sound a practical judgment as anyone, has no doubt whatever 
that it is aculeatum. |
