to retreat, and then proceeds to eat out the "buds" of the young 

 plants in addition to devouring the leaflets. 



Bordeaux mixture sprayed on the plants when they are first set 

 out, or when they first appear above ground, and continued at intervals 

 of a week or two, should act as a deterrent. 



When cabbage and similar plants are set out they should first be 

 dipped in a solution of arseniate of lead, 4 lb. to 50 gallons of water.

Cactus, Echinopsis x Rohlandii Foerster. By Roland Gosselin 

 (Rev. Hort. p. 304, July 1, 1913 ; plate). — The illustration depicts 

 a Cactus of the Cereus type bearing large and very beautiful light 

 mauve flowers some 3 inches in diameter as the result of crossing 

 Echinopsis tubiftora with the pollen of E. oxygona. Some Mendelian 

 data are given concerning other results of crossing. — C. T. D.

Capoc Trees of Togo. By E. Ulbrich (Not. Konig. Bot. Berlin, 

 vol. vi. No. 52, pp. 39-65, September 1913 ; with 2 text figures). — 

 The present communication consists of the report of the replies received 

 from the principal capoc-growing districts to a circular note of queries 

 which was issued by the Colonial Department of the Dahlem Botanical 

 Gardens in 1911. 



The most important outcome of this inquiry is the establishment 

 of the fact that two well-defined forms (or rather, series of forms) 

 of cotton-wool-yielding trees of Ceiba pentandra (L.) Gaertn., occur in 

 Togo. Typical examples of each are readily distinguished, but a 

 complete series of intermediate forms occur between them. The two 

 forms of Ceiba pentandra are : 



(a) Spinous Capoc-yielding trees. This form grows as a large tree 

 with strongly developed basal roots, dark-green leaves, fruits which 

 burst upon the tree, and spinous branches with a spreading habit. 



(b) Non-Spinous Capoc-yielding trees. This type of tree is usually 

 lower in height, has only slightly developed basal roots, light-green 

 leaves which are narrower than those of type (a), fruits which fall to 

 the ground unopened, and the spineless branches are more erect and 

 less spreading than in the preceding form. 



The spineless Capoc trees possess all the qualities necessary for 

 successful culture of the wool. They are not too tall, they do not 

 shed the wool before the fruits fall to the ground, and they have no 

 basal roots or spines to interfere with gathering the fruits. 



This form of tree, however, requires a more fertile soil for its 

 growth than does the spinous type. 



The present article concludes with a description of four cotton- 

 wool yielding species of Bombax which grow wild in Togo. — R. B.
