POLYSTICHUM AXOrLAKE, 177 



deltoid, sliglitly auricled, only occasionally proliferous in the 

 lower part of the rachis. This form differs from the old Pro- 

 liferum in the frond being much narrower and much less 

 proliferous. I am indebted to ^lessrs. Stansfield, of Todmorden, 

 for fronds. 



Arctatum, 31oore. — Found at Barnstaple, by the late Mr. 

 C. Jacjvson. A handsome and large variety, bearing somewhat 

 the resemblance of Lineare, but being, however, less abnormal 

 in its development. The pinnules are tolerably uniform; seldom 

 depauperated. The pinnae are also not confluent into a lengthy 

 linear lobe, but diminishing in the ordinary manner. The 

 pinnules are almost linear, acute, having a very large acute 

 anterior auricle. Xear the base of the frond they are somewhat 

 more oblong, yet even here narrow.
