AGRICULTURAL BOTANY. 



Linnaeus's lectures on the cultivation of plants, M. li. Swederus (Uppmla 

 Univ. Aarsskr. lUOl. JJiuicfcst KA/'. J, pp. 17// + i07).— This is a translation 

 into German of a series of lectures on the cultivation of plants that are sup- 

 posed to have been delivered by Linnaeus at the I'niversity of Upsala about 

 1759. The manuscript was found in St. Petersburg a few years ago. 



The weeds and suspected poisonous plants of Queensland, F. M. Bailey 

 (Brisbane, 1906, pp. 2'io, figs. Jf08). — Brief botanical descriptions are given of 

 the orders, genera, and species of weeds and suspected poisonous plants of 

 (Queensland. In each instance the locality is named from whence the speci- 

 mens were obtained and notes are given regarding their economic, noxious, 

 medicinal, and other properties. With a few exceptions, a portion of each plant 

 is illustrated. 



Triple hybrids, H. de Tries (Bat. Gas., J,l (1909), No. 1, pp. 1-8).— Xn 

 account is given of studies of evening primrose hybrids in which the possi- 

 bilities of so combining the species as to form triple and even quadruple hybrids 

 are described. The author states that twin hybrids are produced when the 

 pollen of (Enothera Jamnrckiana or of one of its derivatives is crossed with the 

 European subspecies of (E. biennis or of CE. muricatd. Triple hyl)rids may be 

 produced by combining one of these with species such as (E. lata and <E. scin- 

 iilhuis. The segregation of characters in the progeny is discussed. 



The chemistry of plants, G. Andre (Chimie Vegetale. Paris, 1909, pp. XII + 

 560, figs. 14). — This is issued as a portion of Encyclopedie Agricole, published 

 under the direction of G. Wery. While essentially an elementary work, the 

 author designed this treatise for those who want to gain something more than a 

 superficial knowledge of the processes of plant nutrition. 



ChaiJters are given on the essential elements, structures, and function of 

 vegetable material in general, after which the function of chlorophyll, forma- 

 tion of intermediate ternary compounds, assimilation and elaboration of nitro- 

 gen, chlorophyll and other plant pigments, germination, respiration, mineral 

 composition, the forms under which various mineral substances are found in 

 plants, and the role of water in the plant kingdom are discussed. 



While the treatment is popular in its nature, the author has incori>orated the 

 results of many recent investigations and states the more recent theories on 

 plant life and processes. 



The bio-chemistry of animals and plants, O. Rosenheim (Sei. Prog. Twen- 

 tieth Cent., 2 (1908), No. 8, pp. 616-699; S (1908). No. 9, pp. 106-123).— This^ 

 is a summary giving the present status of the bio-chemistry of plants and 

 animals, the first part of the pai)er being devoted to a discussion of the nitrogen 

 cycle, including nitrification, denitrification, and nitrogen fixation, the synthesis 

 of proteids, and the history, occurrence, properties, classification, etc., of pro- 

 teids. In the second portion of the paper the significance of proteids in the 

 plant is discussed, and the occurrence and function of a number of other com- 

 l)0unds, such as phytotoxins, toxolecithides, lipoids, inosite. organic phosphoric
