and found near Brooklyn, N. Y., Pennsylvania and Virginia. I thought perhaps it 

 might interest your readers to hear of it so far west as this Will some of your readers 

 tell me how to preserve herbarium specimens of Cacti? — Matthew H. Panton, Juiic-

Recent PuBLicAxroKs. — American Jcmriuil nf ^rieu.ce and Arts, April. The Dic- 

 tionnaire de Botanique, by M. H. Baillon, Paris, is in a fair way to become a bulky 

 work. The third fascicle is now out and about 300 pages will be devoted to the first 

 letter of the Alphabet. The Cretaceous deposits of Spitzbergen have yielded T/ixo- 

 ffiutn, Sequoia, Ci/pern.s, Carer, Alisnia, seven Poplars, t^^o Alders, three Hazels, a 

 Hornbeam, a Beech, four Oaks, an Elm, a Plane-tree, an Ivy, five species of Cornus, 

 two of JSfi/sm, two of Magnolia, a T'dui, three Maples, three Hawthorns, and a veritable 

 fossil strawbery I It seems that the American Mistletoe is making great ravages among 

 the elm and black walnut trees in the latitude of Louisville, Ky. *'As soon as a bunch 

 of mistletoe fixes itself upon a branch, the outward extremity ceases to grow, and finally 

 dies. The tree soon ])resents a clubby appearance, followed by death." The mistletoe 

 grows in great abundance about Hanover, Indiana (fortj- miles from Louisville), Init we 

 have never appreciated that it was such a dangerous customer. It grows on the elm, 

 walnut, honey-locust and various other trees, but we have yet to notice tne first deatlen- 

 ing efiects. We are glad to have our attention called to it and will watch it more 

 closel}'. 



American Nataralixt, April. — We quote: "Fournier gives as the result of his 

 study of the grasses of Mexico the following statement: 'Among grasses Avith sepa- 

 rated sexes, the female fiowers difter very little, if at all, as regards the situation or 

 form of the fioi-al envelopes, when the sexes are borne on different plants ; l)ut when 

 the plant is monoecious the glumes of the two sexes are widely difierent. These dif- 

 fej-ences are most marked in certain genera of Chloridea% normally dio'cious and acci- 

 dentally monoecious.' The grass described by Engelmann imder the name Burhloe 

 daetyloiden is a curious example in point. Beside this is now placed Opizia xfolonifera, 

 of which Presl had seen only the female plant. Although the female flowers of these 

 l>lants differ very widely, their male jilants resemble each other so much that they 

 have been put in the same genus. CasioKtcf/a /iinnilin. is the male form of Bar/doe, and 

 C. anonai/ais the male form of Ojriziay From the Flora of Colorado we (juote the fol- 

 lowing sentence in regard to Buchloe as being of interest in this connection: "Nuttall, 

 who had only the male plant, referred it to the genus Se.sleria, and described it as <v. 

 ffarfi/loides {Gen. \. p. M.) Steudel founded another genus on the female plant, J »- 

 fephora a.villiflora, (Glum. \. p. 111). The true relationship between them was first de- 

 tected by Dr. Engelmann, and clearly set forth by him in his masterly ailicle in the 

 Trans. St. Louis Acad." 



The Gardener's Monthly, April.— An article on "Self-Fertilization and Cross-Fertili- 

 zation of Flowers," is begun by Mr. Meehan in this number. 



Bulletin of the Torrey Botanical Cluh, March and April.— Francis Wollc adds one 

 hundred species to the Fresh Water Algte of our countrj% and C". F. Austin describes 

 several new species of Mosses. 



Field and Forest, April. — Mr. Martindale gives an interesting little note in regard 

 to the Scandinavian herbarium M'hich he purchased at the Centennial. He says that 

 it contains about 1500 species and is ]>rol)ably one of tlie most complete representations 

 of the fiora of Sweden to be found in this country. He mentions two or three points 

 of interest in comparison with our own flora. Sweden has ;{0 species of Ilierachim, 

 but only one Aster and one Soiidago!
