aspera, A. armata, A. infesta and A. sessilifolia. Of the 

 Cyatheas, we may mention C. Concinna, C. Tnssacii 

 and there are plenty of others. So far as the editor's 

 observation goes, prickly tree-ferns are by no means 

 rare. — Ed.] 



Still Another Nephrolepis. — The naming of 

 new forms of the old Boston fern (N. exaltata) goes 

 merrily on. The latest is, to give the full name, 

 Nephrolepis exaltata elegantissima compacta. It is 

 a compact form of that plant with much-divided fronds 

 known as Nephrolepis elegantissima, but in reality a 

 form of N. exaltata as indicated above. While the 

 names given to plants by gardeners and florists have 

 very little significance to the scientific botanist we shall 

 be none the worse for keeping these trivial names in 

 mind. Although rather cumbersome and usually 

 gradiloquent they represent forms that are quite dis- 

 tinct from the view point of the cultivator. 



Permian Ferns. — The note on Coal Measures ferns 

 in the January 1909 Fern Bulletin called to mind a 

 deposit of Permian ferns or fern-like plants discovered 

 in 1906 by one of the field parties of the University 

 Geological Survey of Kansas. We were mapping the 

 Permian-Dakota contact in Washington County, Kan- 

 sas and noted a fern horizon in a layer of limestone 

 concretions near the top of the Winfield (?) limestone. 

 The next day we returned to the exposure with some 

 tools and opened up the deposit. By properly splitting 

 the limestone, whole fronds were exposed in an almost 

 perfect state of preservation. A large quantity of the 

 material was shipped to the University of Kansas 

 where it was identified by Prof. E. H. Sellards and will 

 soon be published, along with other Permian plants.
