Catasetum ochraceum. By R. A. Rolfe (Orch. Bev. p. 327, 

 Nov. 1902). — Interesting particulars of this peculiar Orchid and its 

 history are recorded. — H. J. C. 



Catasetum quadridens, $ x $ . By Sir J. D. Hooker (Bot. Mag. 

 tab. 7864).— Nat. ord. Orchidea, tribe Vandece. Native of ? The 

 nearest affinity, according to Mr. Rolfe, is C. comutum of Demerara. It 

 is monoecious. The flowers are 2 ins. long, the sepals being pale green, 

 with large dark red-purple blotches. The petals resemble them, but 

 the lip is golden yellow speckled with dark purple, and having the margins 

 fimbriate-dentate. — G. H. 



Catalpa bignonioides, and allied Forms. By C. K. Schneider 

 (Die Gart. p. 88, 22/11/1902, splendidly illustrated).— The specimen of 

 our illustration grows at Vienna in the Rathhaus Park. C. ovata (syn. 

 C. Kaempferi), C. Bungei, and C. speciosa are also mentioned, but the 

 above is no doubt the best of all, and is much more used on the Continent 

 than here. Unfortunately, the species is doubtfully hardy, excepting in 

 the southern and western countries of the Continent. — G. B. 



Catalpa, The hardy (U.S.A. Agr. Exp. Stn. Kansas, Bull. No. 108 ; 

 April 1902). — There are two species of Catalpa in the United States— 

 C. bignonioides, indigenous in the South-East, and C. speciosa, first 

 distinguished as specifically distinct by Warder in 1855, inhabiting the 

 Central West. 



From a purely economic point of view the Catalpas are of great 

 value, the annual consumption for railway tree timber alone being 

 considerable, while as post and pole timber the durable quality renders it 

 specially valuable ; indeed it has been said that the Catalpa possesses 

 more and greater advantages than any other indigenous tree. 



The Catalpa plantations at the Agricultural College are said to have 

 given encouraging results, even on very poor thin soils, the trees being 

 adapted for posts in from seven to ten years, and in twenty years are useful for 

 lumber and cabinet work. Under the head of " Commercial Catalpa 

 Plantations " much interesting information is given as to the area and for- 

 mation of plantations in the Forlington district, and where success has 

 certainly crowned the efforts to establish breadths of this most useful forest 

 tree. Appended are a series of illustrations of the Catalpa tree, experimental 

 plantations, sections of the timber, with fruiting branches of the two species, 

 all beautifully executed. Those showing fencing posts which had been in 

 the ground for twelve and fifteen years, and yet, practically speaking, free 

 from decay, are of particular interest, and form an excellent object-lesson. —

Cattleya Brymeriana Rchb. f. (Gartenflom, 1/2/1902, p. 617, pi. 

 1505). — A coloured plate of this Cattleya (which Reichenbach assumed to 

 be a natural hybrid between C. superba and C. Eldorado), from a photo- 

 graph obtained in Brazil. — J. P.
