While it is possible that not enough stems have been meas- 

 ured to give the exact averages for either hyemale or robustum, 

 it is believed that a further examination of material will not 

 materially change the results if care is exercised to count strictly 

 mature stems. The most likely effects will be to throw the maxi- 

 mum stem length for robustum above 34 inches and the raising of 

 the average diameter of the stem and the average number of 

 grooves in the stem, up to or slightly beyond the average for 

 hyemale. The average length of joint in either species will 

 probably not be changed, and all the averages for hyemale as 

 expressed by the Patterson specimens are likely not to be shifted 

 more than one point in either direction. 



I am therefore convinced that robustum is properly only a 

 stouter form of hyemale. It differs from the form in the Eastern 

 States in retaining the teeth of the sheaths, in producing branches 

 more freely, and in being usually larger. 



Extended measurements of this kind are very much to be de- 

 sired in other closely related species, and I take the liberty of sug-- 

 gesting that a similar bond of union may be found to exist be- 

 tween B. laevigatum and B. Funstoni. It is likely, also, that 

 measurements of B. palustre, B. Huviatile and B. arvense would 

 show which has the closest affinity for the so-called B. littorale 

 and probably indicate its parentage if a hybrid.

REMARKS ON SOME FERN WORTS OF WESTERN 

 NEW YORK. 



By E. J. Hill. 



When reading the article of Mr. Gilbert on the "Fern Flora 

 of New York" in the Fern Bulletin for October, 1903, it oc- 

 curred to me that some extension could be given to the geo- 

 graphical range of a few species which occur in the western part 

 of the State, or uncertainties removed and other matters of in- 

 terest added. Being a native of the region, my study of botany 

 and collecting began there, and have been supplemented by visits 

 at various times since. An effort has also been made to keep 

 informed of botanical work represented in the local floras oc- 

 casionally published.
