produced in abundance but reproduction by spores is a 

 precarious business for the spores may not lodge in 

 the proper place. Stolons sent out by the plant, how- 

 ever, can wander on until a good location is secured, 

 and thus the extension of the colony is accomplished. 



Forms of Botrychium obliouum. — It is inter- 

 esting to note that M. A. Chrysler finds the anatomv 

 of Botrychium tematum, intermedium, dissectum 

 and obliquum practically identical and states that no 

 basis is afforded for distinguishing them by this 

 means. The late Geo. E. Davenport after studying 

 the forms sufficiently to write a monograph on the 

 subject, came to a similar conclusion from other indi- 

 cations. It has remained for later plant students to 

 make 'new species founded on the cutting of the sterile 

 segments. Chrysler also finds that the vascular sys- 

 tems of B. mat ricariae folium and B. lanceolatum are 

 much alike. 



POLYSTICHUM ACROSTICHOIDES MULTIFIDUM. Mr. 



Chas. T. Druery has called our attention to the fact 

 that the fern whose name stands at the head of this 

 note was cited as multiiida in a recent number of this 

 magazine when it should have been multifidum. 

 Furthermore it turns out that the fern was originally 

 named mnltifida though the name should have ended 

 in urn to agree with the generic name. The error is 

 due to a mere lack of watchfulness upon the part of the 

 editor and the form name is, of course, multifidum. 

 While such names are not of very great significance, 

 it is well to note that they, like all specific names, 

 should agree with the generic name in gender.
