North American Ferns. ^ D. W. Fellows * gives an account of the 

 fern-flora of Maine. Though the whole of the state has not been 

 explored, it yields 08 species and 10 varieties of ferns, and 27 species 

 and 6 varieties of fern-allies. B. D. Gilbert t describes a new and 

 peculiar variety of Polypodmm imlgare from Pennsylvania. W. N. 

 Clute X gives a brief account of the genus Oleander, and figures one of 

 the species. H. H. Negley§ gives field-notes upon some 14 rare 

 species of ferns and the conditions under which they grow in a remote 

 part of Florida. T. C. Palmer |1 records the reappearance of the rare 

 fern Aspleiiium eheiioides in Chester Valley, Pa., near its original 

 station. It is associated with A. flatijneuron and Gamptosorus, to the 

 former of which it shows some external resemblance. R. J. Smith If 

 somewhat enlarges the narrow distribution of Selaginella Bigelowii in 

 South California. J. H. Ferriss ** has been trying to cultivate in 

 Joliet Park, 111., all the North American ferns. He relates his vicissi- 

 tudes. Some of the species grew like weeds ; others died off at once or 

 in a few months. The Canadian species are as difficult to grow as 

 those brought from rock or desert. For some of them suitable nooks 

 have been found by experiment. The writer has travelled in the 

 South Western States collecting specimens and noting their habitats, 

 but says that much more of such local knowledge is requisite. W. N. 

 Clute tt fignres and describes a curious new form of Osmwida regaJi.x 

 with overlapping orbicular pinnules. It grows in Vermont. W. A. 

 Squires IJ records a new station, in Northern Idaho, for the rare 

 SelagiaeUa Douglasii. Previously it was known only between Northern 

 California and British Columbia. Mrs. J. J. PufPer§§ describes 

 successful attempt to transplant Woodsia ilvensis from the arid exposed 

 rocks on Mount Tom, Mass., to a stone wall in her garden, in which 

 position it now grows luxuriantly. W. N. Clute |{|| continues his check- 

 list of North American fern worts, enumerating 22 species, with their 

 varieties. P. Dowell ITIT describes some habitats of Drgopteris Boottii 

 Underw. in the eastern United States — in Staten Island, New York, and 

 New Jersey. This fern appears to be suited by the same swampy con- 

 ditions which are favourable to the growth of D. cristata, D. GUntoni, 

 D. spimdosa and its subspecies intermedia. The author's observations 

 do not enable him either to prove or to disprove whether D. Boottii is a 

 hybrid ; he points out a few characters which distinguish it from both 

 its proposed parents. Until it has been raised by artificial crossing from 

 these latter, we are not justified in pronouncing it to be a hybrid. The 

 same author *** gives a list of 31 pteridophytes from Staten Island, 

 together with their distribution.
