Lonicera Hildebrandiana. By E. Jenkins {Gard.Chwn. No.771, 

 p. 254 ; October 3, 1901).^ — This handsome plant, which was flowered this 

 summer by the late Mr. Ewbank at Ryde, is commented on, and the best 

 position for its growth discussed. — G, S, S. 



Loquat. Anon. {Jour. Hort. p. 423 ; November 1). — This fruit 

 {Eriohotrya japonica) is figured, and its cultivation in Staffordshire 

 described. — C. W. D. 



Lycaste Micheliana, Cogn. (Cogniaux in Diet. Icon. Orch.y 

 Lycaste, S ; 11/1901). — Introduced by M. Marc Micheli, of Geneva, 

 in 1900, from Mexico. Sepals greenish-yellow ; petals and lip orange, 

 the latter spotted with red ; flowers fragrant. This species much 

 resembles L. aromatica, Lindl. — C. C. H. 



Maize Hybrids. By H. J. Webber {U.S.A. Dep. Agr., Div. Veg. 

 Physiology^ Bull. 22 6 1900).— This bulletin is a contribution to the 

 literature on " Xenia," or the immediate effect of pollen upon the 

 character of the seed or fruit. Experimental evidence is adduced in 

 support of the theory that ''xenia" is the result of the double fertili- 

 sation of the ovule by the two nuclei of the pollen grain, and that grains 

 showing "xenia" are always hybrid. "Xenia" is almost always 

 (perhaps invariably) confined to the embryo and endosperm, while it 

 seldom (or never) extends to the pericarp. Gaertner (in 1848) and 

 Berkeley (see Gard. Cliron. 1854, p. 404) both distinctly assert that 

 " xenia " influences the seed-coats of Peas. The paper is illustrated with 

 four plates, showing the changes in form and colour produced by " xenia " 

 in Maize grains, and the differences between the hybrid plants and their 

 parents. — F. J. C. 



Manures, Effect of {Wobimi 2nd Bep. 1900, p. .98).— Amongst 

 many varieties of Gooseberries, Black Currants, and Raspberries, the 

 bushes being young and soil good, little benefit to crop was found either 

 with 12 or 30 tons of dung per acre, or their equivalent in artificials. The 

 only evidence of eftect of manure was in increased luxuriance of foliage 

 and size of berries in Gooseberries when dunged. 



Apple and Pear trees, when young, show little benefit from various 

 kinds of manuring, the conclusion arrived at being that as long as a 

 tree is growing w^ell, and making sufficient amount of firm new wood 

 every season, it requires no additional manure. 



Growing grass over the roots of young fruit trees is found most 

 injurious, even more so than weeds (due probably to increased evaporation 

 and diminished access of air to the roots). — C. H. H. 



Masdevallia erythrochsete, Rchb. f. (Cogniaux in Diet. Icon. 

 Orch., Masdev., pi. 15 ; 3 /1901). — Introduced by Messrs. Sander, of St. 

 Albans, either from Central America or Colombia, in 1882. — C. C. H. 



Masdevallia Schroderiana (Cogniaux in Diet. Icon. Orch., 

 Masdev., pi. 16; 9/1901).— Introduced by Baron Schroder in 1890. 

 Flowers small, crimson and white, with yellow tails. — C. C. H.
