 a week or two then may have disastrous results later on if the autumn 

 be cold and wet. — E. T. C. 



Carnations, Malmaison Tree, 'Chatillon,' • Madame Bixio.' By 



G. T. Grignan (Rev. Ilort. pp. 14-15, Jan. 1, 1904 ; coloured plate illustrat- 

 ing these two varieties).— Those forms resulted from crossing ' Malmaison ' 

 with a French variety named * Tige de fer ' (iron-stalked) by M. Nonin, 

 Chatillon-sous-Bagneux, near Paris, and as shown by the plates are very 

 fine forms indeed. ' Chatillon ' a very double, broad-petalled, slightly 

 fimbriate form, of a deep rose, and ' Madame Bixio ' (' La Fiancee,' ' Tige 

 de fer ' x ' Malmaison,' double rose), described as white striped with bright 

 cherry- red, but in the plate the white has a nuance of salmon. — C. T. D. 



Catalpa, The Hardy, as a Farm Crop. By W. J. Green (U.S.A. 

 Agr. Exp* Stn. Ohio, Bull. 149). — There are two distinct species of Catalpa, 

 C. bignonioides, or the Indian Bean, and C. speciosa, both being perfectly 

 hardy in this country and fairly plentiful as ornamental flowering trees> 

 For timber purposes both stand in great esteem, the lasting properties of 

 the wood having been long ago recognised, particularly when brought in 

 contact with the soil. Elaborate directions regarding raising the Catalpa 

 from seed, transplanting, and thinning are given, also the usual rate of 

 growth and quantity of timber produced in a given period. For posts, 

 poles, and railroad ties the timber of the Catalpa has been found most 

 valuable.— A. D. W. 



Catasetum monodon. By F. Kranzlin (Gard. Chron. No. 910, 

 p. 854, June 4, 1904).— This new species is said to be a native of Brazil, 

 but nothing is known of its habitat. The plant is described both in 

 English and Latin, but it does not seem to be a very distinct species.

Cattleya Disease. Sur une Maladie des Cattleya. Par MM. Maublanc 



et Lasnior (Bull. Soc. Myc. France, xx. fasc. 8, 1903 ; 1 plate). — This 

 disease has appeared for several years on the leaves of Cattleya around 

 Paris, and is here determined to have at first the fructification of Glceo- 

 sporium (15 20 x 4-6 /<), which is the conidial form. This, it is admitted, 

 may be the same as some other species of Gloeosporium found on Orchids. 

 Under cultivation perithecia were developed on the under surface of the 

 leaves, which produced asci and sporidia (the latter oblong, slightly 

 curved, continuous, 20 25 x 5-7 /<)• The perithecia were developed on 

 dead leaves, and the authors entertain no doubt of its being the perfect 

 and ascigerous stage of the Gloeosporium. — M. C. C. 



Cattleya Mendeli, var. Lackneri (Gartenflora, Jan. 1, 1904, p. 1 ; 



coloured plate). — This Orchid was raised in the nurseries of Herr Otto 

 Beyrodt, of Marienfelde, Berlin. The sepals and petals are white flushed 

 with pink. In the labellum the purple is divided into two distinct zones ; 

 the outer one dark purple Hushed with white, the inner /one being violet 

 veinod with a lighter shade of the same colour. The upper part of the 

 labellum is white, and the throat deep yellow veined with a light yellow.
