204 EXPERIMENT STATION RECORD. 



Contributions to the physiology of woody plants, K. G. Lutz 



(Bcitratj ici.ss. Hoi. FiinOdiick, J {J8!)'j), pp. l-SO; ahn. in Jour. Roj/. 

 Micros. Soc, 1800, Ko. i, p. J 10). — The experiaients of the author with 

 beech trees showed that between October 10 and November 10 there 

 was a large transference of starch from tlie interior of the trunlc to tlie 

 last annual rin^^ and to tlie bark, and that this starch was then trans- 

 formed into a fatty oil and glucose. If the leaves were removed, the 

 succeeding- growth was destitute of vessels and the tree used up its 

 reserve food material in forming new buds. When pines were stripped 

 of their leaves, very few buds were formed. If this was done early in 

 the season, the reserve materials were used up and no increase in thick- 

 ness took place. 



The point of divergence of Monocotyledons and Dicotyledons, C. E. I^essky 



{Presetiicd he/ore Sec. ^' of the American Jusocialiou for flic Adraiicciiieiif of Science, Aug., 

 1SD6; ahs. in Science, n. ser., 4 {1S96), 2\o. 91, px). 4oS-440).— The author gives his 

 opinion relative to the evolution of these great subdivisions of plants. 



A comparative study of the development of some anthracnosef3 in artificial 

 cultures, Bertha Stoxeman {Presented hcfore Sec. (i of fhe American Association for 

 ihe Advancement of Science, Anfj.,lS'96; ahs. in Science, n. ser., 4 {1896), No. 91, j>. 436). — 

 About 30 species were studied with a view to their separation or definition as based 

 upon their morphological characteristics. 



The significance of the compound ovary, C. E. Bessey {Fresenfed before Sec. G 

 of ihe American Association for tlie Advancement of Science, Anf/., 1S96; abs. in Science, 

 n. ser., 4 {1S96), No. 91, 2yp- 434, 435). — The origin, development, biological signifi- 

 cance, and the application in systematic botany of the compound ovary were dis- 

 cussed. 



Remarks on the northern species of Vitis, L. 11. Bailey {Presented before Sec. G 

 of tlie American Association for the Advancement of Science, Au(j., 1S96; abs. in Science, 

 n. ser., 4 {1S96), Xo. 91, p. 438). — Notes were given on the .systematic position of cer- 

 tain native grapes. 



The origin of sugar in the beet, F. Stkohmer (Xeue Ztschr. IHihen:. Ind., 37 {1896), 

 No. 11. pp. 137-143). 



A contribution on the anatomy of the fruit of the pear and apple, J. Mal- 

 FATTi {Ztschr. Nahrunf/s. Untersuch. nnd Hug., 10 {1896), No. 16, pp. 265-,269, fuia. 10). 



Abnormal hickory nuts, F. H. Herrick {Amer. Jour. Sci., ser. 4, 3 {1896), No. 10, 

 pp. 258-263, pi. 1, figs. 12). 



Sensitive organs of the Leguminosse and Oxalideae, M. RoDRic.rE {Arch. sci. 

 phys. et nat., 32, No. 12; abs. in Bot. CentbL, 67 {1896), No. 11, p. 329). 



The most important adaptations for the protection of plant organs, G. 

 Ramme (Die wichtigsten Sc]nit:ei)irichfHngen der Vegetationsorgane der Pfianzen, Pt. II, 

 Osterprogramm, Fredic. L'eal Gyntnasium, Berlin, 1895, pp. 25; abs. in Bot. CentbL, 67 

 {1896), No. 9-10, pp. 289, 290). 



Structures of the embryo sac, J, ^I. Coulter {Presented before Sec. G of the 

 American Association for the Adrancement of Science, Aug., 1896; ahs. in Science, n. ser., 

 4 {1896), No. 91, p. 431). — The author gives modified definitions of egg apparatus, 

 primary endosperm cell, and antipodal cells. 



A contribution to our knowledge of the relation between growth and turgor, 

 E. B. Coi'ELAND {Presented before Sec. G of tlie .American Association for tlie Advance- 

 ment of Science, Aug., 1896; abs. in Science, n. ser., 4 {1896), No. 91, pp. 432, 433). — The 

 author reported experiments with seedliugs of Vicia faba grown at different temi)er- 

 atures. He concludes that rapidity of growth regulates turgor rather than the 

 turgor regulating growth.
