Japanese Dwarf Trees. By M. Tsumura {Jour. Hort. p. 536 ; 

 December 12). — Abstract of a lecture before the Japan Society giving 

 some account of the rearing of these. — C. W. D. 



Jugflans eordiformis. By W. Bean {Gard. Cliron. No. 773, p. 292 ; 

 October 19, 1901). — This Walnut, a Japanese species originally described 

 by Maximowicz in 1873, is being sent out by some Continental nurserymen 

 and promises to be a very handsome tree. Its leaves are often over 2 feet 

 long, and the male catkins are 12 or more inches in length. It is said to 

 be likely to thrive in this country. — G, S. S. 



Juniper Disease. By A. v. Jaczewski {Zeit. f. Pflanz. xi. pp. 203- 

 207, 7 figures; 11/1901).— Description of mode of attack and the 

 characters of a fungus parasitic on Juniper, abundant in the Smolensk 

 district of Russia. It agrees with Coryneum jwiij^erimim, Ellis, of North 

 America, but in agreement with Karsten, who found it in Finland, 

 Jaczewski places it in the genus Exosporium, under the name Ex. juni- 

 ])erinum (Ellis) Jacz. — W. G. S. 



Kiefer Pear, past, present, and future. By J. S. Harris 



(U.S.A. Hort. Soc. Maryland, 1898), — Previous to the introduction of 

 the Kiefer Pear, the Bartlett was the popular Pear. The former has 

 materially improved in the Maryland climate, and it is now a favourite. 

 Instructions are then given as to cultivation. It is the general opinion 

 that less than one fifth of the Kiefer Pear trees now planted in the 

 State have reached the age for full crops. In this lie the hopes for 

 the future, since the Kiefer Pear has " attained to a dangerous popularity."

Kochia SCOparia. Anon. {Gard. Chron. No. 777, p. 359, fig. 110; 

 November 16, 1901). — A curious plant belonging to the order Clieno- 

 l^odiacece. Forms a very compact bush. In autumn its leaves turn a 

 reddish-crimson colour, and it is then a very striking plant. — G. S. S. 



Lselia (Cattleya) x exoniensis (Leonard Barron in Amer. Gard. 

 xxii. p. 861, fig. 176; 21/12/1901).— One of Mr. Dominy's fine old 

 hybrids obtained in Messrs. Veitch's nurseries at Exeter in 1863. 

 Sepals and petals delicate blush, lip velvety rose-purple with white 

 margin, throat golden-orange veined purple. This hybrid is of rather 

 doubtful parentage ; it was at first thought to be from Cattleya Mossue $ 

 and Lcelia imrimrata ^ . Mr. Barron thinks that it is from L. crifipa 

 iind L. imrijurata; but Mr. Rolfe (in Orc/t. i^cr. 1893, p. 5 ; 1896, p. 258) 

 says it is certainly a Lcelio- Cattleya, and from L. crispa and either 

 C. Mossice or C. lahiata. Judging from the excellent photograph in 

 Amer. Gard., I think there is little doubt that it is from L. crispa and 

 C. MossicE.—C. C. H. 



Lgelia flava aurantiaca (Cogniaux in Diet. leon. Orch., Lcelia, pi. 

 19a; 5/1901). — Flowers larger than type, bright orange yellow. L. 

 Coivani, introduced from Brazil in 1898 by Messrs. Cowan, of Liverpool, 

 is probably synonymous with this. — C. C. H.
