A RICH FERN LOCALITY. 



IN the October Bulletin Dr. Underwood reports the finding, 

 near Jamesville, Onondaga county, New York, of thirty-four 

 species of ferns within a circle whose diameter was not over 

 three miles ; twenty-seven of which species grew in the immediate 

 vicinity of Scolopendrium Lake, and asks if there is any other local- 

 ity in the United States where so many species of ferns have been 

 found within such narrow limits. 



Near Pittsford, Rutland county, Vermont — the end of a tam- 

 arack swamp, a field less than a mile away, and some limestone 

 cliffs three miles from both the field and the end of the swamp, 

 form the corners of a triangle. Within this triangle I have found 

 thirty-nine species and eight varieties (or so-called varieties), al- 

 though not quite so many species at any one point as Dr. Under- 

 wood found at Scolopendrium Lake. 



My list is as follows: Species — Polypodium vulgare, Adian- 

 tum pedatum, Pteris aquilina, Pellsea atropurpurea, P. Stelleri, 

 Asplenium platyneuron, A. Tricomanes, A. angustifolium, A. 

 acrostichoides, A. ruta-muraria, A. Filix-fcemina, Camptosorus 

 rhizophyllus, Phegopteris Phegopteris, P. Dryopteris, Cystopteris 

 bulbifera, C. fragilis, Dryopteris Noveboracensis, D. thelypteris, 

 D. spinulosa, D. cristata, D. Boottii, D. Goldiana, D. marginahs, 

 D. acrostichoides, D. cristataXmarginalis, Onoclea sensibilis, O. 

 Struthiopteris, Woodsia Ilvensis, W. obtusa, Dicksonia punctilo- 

 bula, Osmunda regalis, O. Claytoniana, O. Cinnamomea, Botry- 

 chium matricariaefolium, B. simplex, B. lanceolatum, B. ternatum, 

 B. Yirginianum and Ophioglossum vulgatum ; varieties — Dryop- 

 teris spinulosa intermedia, D. spinulosa dilatata, D. cristata Clin- 

 toniana, D. acrostichoides incisa, Onoclea sensibilis obtusilobata, 

 Osmunda cinnamomea frondosa, Botrychium ternatum obliquum, 

 B. ternatum dissectum. — Margaret S/osson, Summit, N. J. 



— Mention has several times been made in this journal of the 

 revision, which is being made by Dr. L. M. Underwood, of the 

 ferns of the Botrychium ternatum group. In a paper recently 

 presented before the Torrey Botanical Club, four new species 

 have been segregated. When the work is completed a synopsis 

 of it will be published in these pages.
