Oowea angustifolia. By Sir J. D. Hooker (Bot. Mag. tab. 7870).

Cucumbers and Tomatos, Root-knot Disease in. Anon. {Jour. 



Bd. Agr. vol. ix. No. 3, 1902, p. 360, pi. v.). — This root-disease is effected 

 by the Root-knot Eelworni (Hcterodera radicicola). The remedies given 

 are carbolic acid, one part to twenty parts of water. Thoroughly saturate 

 the soil three times at intervals of a fortnight. 11 A second remedy is 

 mixing the soil intimately with gas-lime. 



" In either instance the soil so treated must remain for at least six 

 weeks before it can be used. 



" 'When soil in a house is infected, it is safest to remove the whole 

 and treat it outside ; the interior of the house should then be thoroughly 

 washed with carbolic acid one part, water eight parts."

Cyclamen europseum. By C. Wolley-Dod (Garden, No. 1613, 

 p. 261, 18/10/02). — Nearly every week in autumn I see mistakes made in 

 the flower notes of gardeners, who wrongly call the hardy autumn Cyclamen 

 C. europaum. I only know one hardy autumn Cyclamen, and its right name 

 is C. neapolitanum, Tenore. C. neajjolitanum, native of South Italy and 

 Sicily, begins to flower in ordinary seasons about the last week in August. 

 G. europium, Linna?us, is a native of South-Eastern France and Switzer- 

 land. In spite of repeated importations from Aix-les-Bains, where it 

 abounds, I have never been able to make it thrive. — E. T. C. 



Cymbidium x Mantinii {Orch. Rev. p. 361, fig. 37, Dec. 1902).— 

 Historical and other particulars are included with the illustration of this

 2-3 ft. long. Raceme pendulous, 10-20 fld. ; flowers 2 ins. broad. Sepals 

 and petals greyish white, with a blood-red central streak. — G. H. 



Cypripedium x auriferum (L. Linden in Bind. xvii. t. 771 ; 

 1/6/1902). — A hybrid of doubtful parentage, raised, it is said, from the 

 same capsule as C. x Beechnani, but totally different. — C. C. H. 



Cypripedium x Glonerianum (L. Linden in Bind. xvi. t. 753 ; 

 25/11/1901). — A new hybrid between C. Victoria- Mar ice and C. x 

 Beeanu?n, raised by Messrs. Linden of Moortebeek, interesting as the first 

 hybrid from C. Victoria-Mar ice. — C. C. H. 



Cypripedium x Stepmaniae (L. Linden in Bind. xvi. t. 765 ;
