566 EXPERIMENT STATION RECORD. 



Concerning Cinctractia seymouriana, P. Magnus {Ber. deut. lot. Ges., 14 (1896), 

 No. 9, i)p. S91, 59^").— This parasite was first described as UsHlago crus-galli n. sp. by- 

 Tracy and Earle (Torrey Bui., 2.2 {1S95), p. 175), hence the name becomes, with the 

 change necessary in transposing it, Cinctractia crus-galli. 



The common Ustilago of maize, J. C. Akthuh (Bot. Gas., 23 (1897), No. 1, jijp. 

 44-4:Q).—'Y\\& author has investigated the synonomy of the common corn smut and 

 states that the name shouhl be written Ustilago zco'. 



Some observations on Uredineae, H. T. Soppitt {Gard. Chron., ser. 3, 21 {1897), 

 No. 520 pp. 67, GS). — Notes are given of Puccinin historta, the a'cidial host of which 

 is Conopodiiim deiiudatitm. 



Contributions to the anatomy and physiology of the lower organisms, 

 E. Crato (Beitrdge Biol. Pflanz., 7 (1896), No. 3, p. 407; abs. in Naturiv. Bundschau, 

 12 {1897), No. 1, pp. 7-9). 



Some recent biological investigations, F, Hildebrand {Ber. deut. bot. Ges., 14 

 {1896), No. 9, p. 325). — Notes are given of the sterility of certain crucifers to their 

 own pollen and changes observed in various plant stocks, as dahlia, petunia, and 

 cyclamen. 



Effect of bacteria on germination, A. Lagervall {Red. verks. Ultuna landtbruk- 

 inst, 1895, pp. 49-52; abs. in Centbl. Bakt. und Par. Allg., 2 {1896), No. 22, pp. 714, 

 715). — Experiments are reported on the effect of bacteria on the germination of rye, 

 wheat, and peas. Sound seed and some that had their seed coats punctured were 

 inoculated and then germinated. In each case the check Jots gave the highest per- 

 centage of germination. Where the seed coats were injured the germination of the 

 inoculated seed was lowered considerably below that of the check. 



Investigations on the formation and regeneration of periderm, epidermis, 

 cork, and cuticle, H. Tithmann {Pringsheim's Jahrb. w/ss. Bot., 30 {1896), No. 1, pp. 

 116-154). 



Contributions to the knowledge of artichokes, G. Meyer {Ber. deut. bot. Ges., 

 14 {1896), No. 9, pp. 347-362, pi. 1). — Studies are given of the morpliology, anatomy, 

 and physiology of artichokes, Helianthus tuberosus. 



On the structure of the fundamental protoplasm of a species of Mortierella, 

 L. Matrxjchot {Conipt. Bend., 123 {1S96), No. 26, pp. 1321-1323). 



On the correlation of grow^th as a consequence of the mechanical checking 

 of growing, F. Hering {Pringsheim's Jahrb. tviss. Bot., 29 {1896), pp. 132-170, figs. 4; 

 abs. in Bot. Centbl., 58 {1896), No. 12, pp. 405-408). 



Pollen bearing vs. plant vigor, M. G. Kains {Garden and Forest, 10 {1897), No. 466, 

 p. 38). — Notes are given of some experiments in emasculating llowers that seem to 

 indicate au increased vigor in the plants thus treated.
