Date Trees in Spain [Jicr. Ilort. Bcbjc, May 1901.)— Contrary to 

 the usual opinion that dates do not ripen in S. Europe, there is at least 

 one locality where trees produce excellent fruit. Elche is a small town 

 near the ^lediterranean which has an "oasis" of Date trees yielding 

 excellent fruit equal to those of the Algerian Sahara. They were intro- 

 duced and grown by the Moors when ruling Spain ; to whom also was the 

 introduction of the Orange due into Valencia and Portugal. The Dates are 

 of a good variety. They are multiplied, just as the African Arabs used to 

 do it, by separating the shoots from the base and not by sowing the stones. 

 Twenty-five female trees are fertilised by means of one male. — G. H.

Dendrobiums, Hybrid. By H. J. Chapman {GanJ. M(uj. 2471, 

 p. 1 18 ; 9 o 1901). — A synopsis of all hybrid varieties of Dendrobium 

 in cultivation. The parentage of each hybrid is given, and in most cases 

 the name of the raiser and place of origin. The descriptive notes in 

 many instances are insufficient for identification, but the list is undoubtedly 

 valuable, as it includes no fewer than eighty-four hybrid varieties. The 

 account is continued in the following number (2472). — W. G. 



Dendrobium (Stachyobium) Jonesii, Piendle. By Dr. A. B. Kendle 

 {Juiirn. Bot. 402, p. 197; -Iiinc 1901.)- Description of a new species 

 received by Mr. J. Sparkes from Mr. Arthur Owen Jones, J. P., Nortli 

 Queensland. The species is nearly allied to D. gracilicaule, F. Muell : 

 and possibly identical with D. (j mcilicaulc var. Howeamoii, Maiden, from 

 Lord Howe Island. It is tropical, and was flowered by Mr. Sparkes at 

 Ewhurst, Surrey, in January 1901. — G. S. II.
