NOTES MD NEV5. 



The January number of the Fern Bulletin contains an illustrated 

 article by Mr. Will R. Maxon on the finding of great numbers of 

 young plants of the rare Hart's-tongue fern {Pliyllitjs Scolopendriuni) . 

 The locality is at Green Lake, two miles east of Jamesville, N. Y., 

 and only a few miles from the well-known Chittenango Falls station. 

 According to Mr. Maxon, the youngest frond form is simply spatulate, 

 becoming somewhat lobed. The frond shade is successively spatulate, 

 spatulate-oval, cordate, ligulate-cordate, and in the more mature fronds 

 simply ligulate with auriculate or cordate base. 



A new fern, under the name of Botrychiuvi tenebrosuni, is de- 

 scribed by Mr. A. A. Eaton in the last number of the Fern Bulletin. 

 It is allied to both B. simplex and B. matricaricB folium^ and has the 

 "sterile lamina above the middle, often immediately under the fertile, 

 short-petioled, simple, lobed or usually with 1-3 pairs of distant, 

 alternate, lunate, decurrent, entire segments." The fertile division is 

 usually short-stalked, simple or with one or two short branches. The 

 spores are very large and roughened. It grows in rich, shady situa- 

 tions, usually among maples at the borders of swamps, and has thus 

 far been found in Rockingham county, N. H., Essex county, Mass., 

 and Charlotte, Vt. 



In the April, 1898, number of Plant World, Dr. Edward L. 

 Greene described an apparent case of parthenogenesis in Antennaria 

 neglecta, a newly-detected species found in the vicinity of Washington, 

 D. C. In this connection it is interesting to note that Dr. H. O. Juel 

 reports in the BotaniscJie Centralblatt, vol. 74, pp. 369-37?, that he has 

 recently observed a similar phenomenon in the European Antennaria 

 alpina. He found in general only female plants, and when the male 

 plants were obtained the pollen was either entirely lacking or feebly 

 developed. In the species described by Dr. Greene the male plants 

 were common enough, but they were in flower about two weeks in 

 advance of the female plants, even when growing together, so that, 

 by the time the stigmas are developed in the female plants, the flowers 

 of the male are dry, dead, and their pollen gone. Dr. Greene did not 

 study minutely the species he mentioned, and it would be extremely 

 interesting to know whether the pollen is not functional or whether 

 the parthenogenetic state has been induced by the different flowering 

 times of the two sexes. We hope some of our readers will be tempted 

 to make observations in this interesting field during the coming season.
