Two Odd Ophioglossums. 



While collecting Ophioglossum vulgatum on July 12, I found 

 two that present an interesting case of reversion. One of these 

 has a spike with 19 sporangia on one side, on the other side the 

 six terminal sporangia were normal. Below this there was no 

 evidence of fruiting, the axis being expanded and leaf-like. The 

 other plant had a spike 1 in. long, the lower half being normal, 

 and the upper flat and leaf-like. This shows that the spike is a 

 modified leaf, which, of course, was known before ; but it is re- 

 markable that in a plant of such simplicity the essential organs 

 should be so completely aborted. Botrychium presents fertile 

 sporangia, or even fertile spikes, on the sterile branch, but I have 

 never found the spike reverting to a leaf.— A. A Eaton. 



OWR MISeELLAMy. 



Mr. Howard P. Wells of Philadelphia, has recently collected 

 a plant of Asplenium ebenoides in Monroe county, Pa., some ten 

 miles above the Delaware Water Gap. The plant was surrounded 

 by luxuriant specimens of the walking fern and ebony spleenwort. 



Polypodium polypodioides is quite common here. Its favorite 

 places of growth are on rocks and tree trunks near the ground It 

 is most commonly found on rocks where there is but little 

 earth, and often a mass of it may be stripped from the rock leaving 

 it bare. In time of drought it will roll up and seem dead, but a lit- 

 tle moisture will soon revive it. I have rarely found it on tree 

 trunks, though Chapman gives that as its place of growing. — H. A.

In the article "Dryopteris simulata in Maryland," it may have 

 struck many of the readers of the Bulletin as strange that the 

 sterility of D. thelypteris growing near D. simulata was particu- 

 larly mentioned. In Mr. Davenport's original article it was stat- 

 ed that the latter species is found "growing naturally and fruiting 

 heavily under conditions where D thelypteris is invariably weak- 

 growing and sterile." My mention of the fact was to confirm this 

 argument against the hybridily of D. simulata, first advanced by 

 Mr. Davenport. — C. E. Waters. 



Having lived not far from Atsion. N. J. for some years, I visit- 

 ed the Schizrt3a locality several times. At Quaker Bridge the 

 plant was found ; I think on the left side of the bridge going from
