BOTRYCHIUM TERNATUM f. ALABAMENSE (Maxon.) 



B. alabamense Maxon. Another of the ecological 

 forms of the common grape fern. 



ASPLENIUM PLATYXEUROX INCISUM (E. C. Howe) 



is offered as a substitute for A. ebeneum Hortouac 

 Dav. or A. platyucurou Hortouac (Day.) It may well 

 be questioned whether the law of priority should be 

 either expected or allowed to interfere with the name 

 of a mere monstrous form of a fern. A plant well- 

 known under a form name is not in any need of a 

 change. 



Poly podium vulgare xixwcristatum Moore reported in 

 Gray's Xew Manual of Botany is properly the yariety 

 bifido-multifidum Druery. The plant is a mere mon- 

 strous form and not in any way entitled to a place in a 

 work supposedly dealing with normal species and varie- 

 ties, but since it has been listed under an erroneous 

 name it may be pointed out that when Mr. Gilbert 

 made his study of Poly podium vulgare in America he 

 had a set of named British forms for comparison sent 

 by Mr. C. T. Druery. In this set were both cristatum 

 and bifido-multifidum and Air. Gilbert was most posi- 

 tive that the latter, and not cristatum is the form found 

 in America. 



Death of J. G. Lemmon. — Prof. J. G. Lemmon 

 died in Berkeley, Calif., Nov. 24, 1908, aged 74 years, 

 Prof. Lemmon was one of the best known botanists 

 on the Pacific Coast and contributed much to our 

 knowledge of the ferns of that region. A species of 

 Polystichum found near Mt. Shasta, California, and 

 at first referred to Aspidium mohroides was later 

 named in his honor by Dr. Underwood.
