losa, so beautifully figured by Moore in his "Nature Printed 

 Ferns." Let me transcribe a few sentences from Moore's de- 

 scription. Fronds "bipinnate above, tripinnate below; longest 

 pinnae nearly six inches long and about two inches wide just 

 above the base ; posterior pinnules on lower pinnae largest, one 

 and three-fourths inches long; stipes one- third to one-half the 

 entire length and clothed sparingly with ovate, bluntish or 

 lanceolate-pointed scales, which are generally pale brown, 

 scarcely tawny. Fructification is copious over whole frond and 

 forms two lines on each of the smaller pinnules or on the lobes of 

 the larger ones ; and the sori are covered by indusia which are 

 fringed with stalked marginal glands." These are the chief 

 points, except that the rachis and under surface are also covered 

 with glands when the fronds are young. These do not appear in 

 our mature specimens. In a general way, the description fully 

 agrees with the ferns I have gathered, and Mr. Clute sent me a 

 frond of the same from some place in Connecticut, except that it 

 is rather smaller. My fronds are three feet long and nine inches 

 wide. Without taking note of minute details, I should say that 

 this' was a good form of dilatata. It is broad at base, and has 

 the prolonged posterior lower pinnules of that variety, but is 

 larger, and longer than, and not so nearly deltoid in shape as the 

 common Rocky mountain form. It certainly does not agree with 

 either spinulosa or intermedia, unless it should be claimed that 

 the glandular indusium ought to rank it with the latter, irre- 

 spective of other characters. But if so, then how can our smooth 

 involucred form be ranked under the same name as the form with 

 glandular indusia found abroad ? The fact is that such a dis- 

 tinction is too trivial to offset broader and more general charac- 

 teristics. Perhaps it might be advisable, in order to give this a 

 local habitation and a name, pending the revision of this whole 

 section of Dryopteris which must be made some day, to style 

 this form Dryopteris spinulosa glandulosa, as I have no doubt 

 it is to be found in many parts of the country.

— Miss Gertrude E. Dane writes of finding several plants of 

 Onoclea sensibilis, var. obtusilobata, at Pepperill, Mass., from 

 which the sporangia disappeared as the fronds matured. She 

 asks if anyone has found this variety with fully developed spores. 



— Mr. C. C. Kingman reports finding a large patch of Marsilia 

 quadrifolia on the Concord river, near Billerica, Mass.
