§ 153. Publications.—1. American Journal of Science and Arts. 
The important paper by Dr. J. H. Gilbert, F.R.S., etc., on the 
“Sources of the nitrogen of vegetation in general, and of agricultural 
production in particular,” begun in the January No., and continued 
in that of February, is completed in the March No. In the February 
No. is a notice by Dr. Gray, of Darwin’s new work, on the “ Effects 
of Cross and Self Fertilization in the Vegetable Kingdom,” and Prof. 
Farlow has some interesting notices of European Cryptogamic publi- 
cations in this and the April No. In the March No., Dr. Gray favors 
the use of the terms dextrorse and stnistrorse, as viewed from without; 
as a common screw, in which the spiral rises towards the right, is 
recognized as a right-handed screw. Grandeau and Bouton find that 
the stem of the mistletoe differs essentially from that of the tree on 
which it grows. In the April No., Dr. Crozier, of Louisville, Ky., 
tells of the destruction of forests of black walnut by the American 
mistletoe (Phoradendron flavescens, Nutt.).—2. Field and Forest for: 
Feb. has notes on the preservation of fungi, by M. E. B., and an 
interesting account of Botany at the Centennial Exhibition, by Dr. 
Vasey.—3. Botanical Gazette: The February No. contains a list ot 
Illinois lichens, by J. Wolf; a useful notice of changes in botanical 
nomenclature since the publication of the last edition of Gray’s 
Manual, by Dr. Porter; a continuation of Dr. Garber’s botanical 
rambles in East Florida; and a list of additions to Mr. J. Schneck’s 
Flora of the Lower Wabash Valley. In the March No., Dr. Porter 
describes a new species of Prunus (P. Alleghaniensis), from Western 
Pennsylvania: “Stone turgid, somewhat obovoid, with a blunt point, 
a shallow groove on one side, and a broad flat ridge on the other. 
Nearly allied to /. maritima, Wang. var. b. T. & G. (P. pygmea,

of Oregon ; Mr. Austin gives Bryological notes; Mr. Green records 
Verbascum Thapsus, L., Lepidium Draba, L., and Datura Tatula, L., 
as introduced into California; and Mr. Schneck an interesting dis- 
covery of root leaves of Alisma Plantago.—4. Onion Smut: An 
Essay presented to the Massachusetts Society for Promoting Agri- 
culture, by Prof. W.G. Farlow. This new fungus vo Cepule, 
Frost, MS.) seems nearly confined at present to New England, where 
it is becoming mischievous, and is supposed to be derived from some 
wild onion.—5. Prof. Farlow sends us also, Remarks on some Alga 
found in the water supplies of the City of Boston.—6. Woolson & 
Co.’s Price List and Descriptive Catalogue of Handy Perennial Plants. 
Passaic, N. J., P. O. Box 180.—7. forest Culture and Eucalyptus
