No. 2, pp. 85-100, pi. 1, figs. 7). — An examination of the material of tlie Austra- 

 lian desert kumquat preserved in the herbaria of Eurox)e and America and a 

 study of living plants novs^ growing in the greenhouses of this Department lead 

 the author to conclude that this plant is out of place in the genus Atalantia, 

 being much more closely related to Citrus. The author here proposes the name 

 Eremocitrus for this genus, which, as far as known, includes only one species, 

 E. glauca. 



This species is described with reference to its distribution, hardiness, drought 

 lesistance, uses, and value for breeding purposes. Attention is also called to the 

 general need for taxonomic study of the wild relatives of cultivated plants. A 

 review of the literature cited is given. 



The Australian desert kumquat can be readily grafted or budded on all of the 

 commonly cultivated species of Citrus and the various species of Citrus graft 

 easily on this plant. It is also believed that the desert kumquat will hybridize 

 with different species of Citrus. Hence its value for breeding new types of 

 hardy citrus fruits is suggested. 



Babylonian dates for California, P. B. Popenoe {Pomona Col. Jour. Econ. 

 Bot., 3 (WIS), No. 2, pp. 459-477) .—This comprises a descriptive list of the 

 varieties of dates grown in Babylonia. The list is prepared both with reference 

 to the utilization of these varieties in California and also as a guide to future 

 visitors to Babylonia. The author considers this region as the most promising 

 from which to draw a large supply of high-grade offshoots for the United States. 



Statistics on the production, of grapes and olives in 1913 (Estadistica de 

 las Prodncciones Viticola y OUvarera en el Ano 1913. Madrid: Oovt., 1914, 

 pp. 8). — This is the usual statistical review relative to the production of grapes, 

 wine, olives, and olive oil in the various regions and Provinces of Spain (E. S. 

 R.. 29. p. 439). 



Study of the influence of various grape stocks on the quality and quantity 

 of the harvest, H. Faes and F. Porchet {Etude de Vlnfluence de Divers Porte- 

 Greffes sur la Quality et Quantity de R6colte. Lausanne, 1914, PP- 4^, figs. 

 29). — An account of this work has been noted from another source (E. S. R., 

 30, p. 43). 



The direct bearers, G. Verge (Prog. Agr. et Vit., {Ed. VEst-Centre) , 84 (1918). 

 No. 50, pp. 757-759; 35 (1914), Nos. 1, pp. 15-27, figs. 2; 2, pp. 48-53; 3, pp. 

 84-89; 5, pp. 153-156; 6, pp. 175-180. fig. 1; 7, pp. 215-218, fig. 1; 8, pp. 247-251;

 fig. 1; 13, pp. 408-412, fig. 1; /.}, pp. 440-443; 15, pp. 4S8-474; fig. 1; 17, pp. 520- 

 527, figs. 2; 18, pp. 563-567). — The author here summarizes observations made 

 during the past 15 years on direct-producing hybrid grapes growing in the 

 Montpellier experimental vineyard. 



Summing up his observations as a whole, the author concludes that there is a 

 considerable choice of direct-bearing hybrid grapes to meet for the most part 

 conditions of climate, production, etc., but in order to secure longevity all of 

 these hybrids should be grafted. 



Forcing strawberries with, ether and with warm water, G. Bultel (Jardin, 

 28 (1914), No. 652. pp. 120, 121, fig. 1). — In continuation of previous investiga- 

 tions (E. S. R., 27, p. 145) the author made in 1912 a comparative test of 

 ether vapor and the warm water bath (E. S. R., 23, p. 40) for forcing straw- 

 berries. Both processes were satisfactory In producing early fruit. The test 

 was repeated in 1913 with similar results; hence both processes are recom- 

 mended for the production of early strawberries.
