imagine, however, that there were very few specimens of this 

 fern, as it was priced very high, and Eaton says it was "scantily 

 collected." The final result of Eaton's examination will be found 

 in his series of " New and Little-Known Ferns of the United States. 

 No 13." published in The Bulletin of the Torrey Botanical Club 

 of March, 1883, It appears under the head of Asplenium Glenniei 

 Baker. Prof. Eaton says: "It is a small fern growing in little 

 tufts like A. montanum, but the fronds are lanceolate, etc., etc. 

 The fern comes near the Old World A. fontanum, but is not closely 

 allied to any of our common species. I am obliged to Mr. Baker 

 for the identification." 



So near and yet so far! On the whole, it was better to have 

 Asplenium Glenniei added to the United States flora than A. fon- 

 tanum, as the former is, so far as known, a much rarer species in 

 the world at large. Besides, as you have shown, A. fontanum 

 does occur in the eastern states, while Arizona is the only region 

 " in this country " where A Glenniei has been found. 



URING the spring of 1896, while examining specimens of 



the plant subsequently published as Isoetes Eatoni, I came 



across one of very peculiar aspect. The leaves were tor- 

 tuous and interlaced or "snarled," the macro-spores large and 

 crested, the microspores present in about equal quantity, the 

 sporangia spotted. A minute search among hundreds of speci- 

 mens failed to discover another, and the only specimens in my 

 herbarium of similar aspect were some collected by Macoun on 

 Vancouver Island in '90 and sent under name of Xuttalli (the real 

 Nuttalli was, however, sent from the same section). Wishing to 

 determine whether this was a freak or a new species, 1 made 

 extended search in 1896 at the type locality of Eatoni. The pond 

 is formed by damming Powow River in East Kingston, N. H., so 

 it floods a space X~K mi l e wide and 1^ miles long, extending 

 back well into Kingston. 



In the lower part of this pond — the type locality f or Eatoni — the 

 search was futile ; but in the upper part, in Kingston, I found it in 

 the greatest abundance, in places lining the banks in a strip a rod 

 wide and 4 or 5 rods long, to the utter exclusion of everything 

 else, the leaves, about 18 inches long, being so close set that they
