Caralluma crenulata, Wallich. By A. Berger (Gard. Chron. 

 No. 889, p. 19, fig. 9 ; Jan. 9, 1904). — This rare species, which has 

 been flowered for the first time in Europe by Sir Thomas Hanbury in his 

 garden at La Mortola, was received by him last May. The stems are 

 irregularly branched, and from 2 to 6 inches in length. The flowers are 

 about an inch in diameter, and are yellow in colour, nearly covered with 

 dark brown-red spots and lines ; they grow in a terminal umbel, and are 

 nine in number ; " the colour and shape of the flowers are very pretty, 

 and the scent is not at all disagreeable. I hope to be able to propagate 

 the species, as it makes subterraneous shoots, which soon make roots, and 

 help to increase the plants." — G. S. S. 



Carbonic Acid, Plants Grown in Excess of. By E. Demoussy 

 (Compt. Bend. Nov. 1904, p. 883). — A series of experiments proved that in 

 the majority of instances plants benefited by being grown in an atmosphere 

 containing carbonic-acid gas in excess of the quantity present in the 

 ordinary air. The average augmentation of gas was to five times the 

 quantity normally present in the atmosphere. The plants experimented 

 upon were grown in closed glass cases for two months, and included 

 sixteen different families, among which may be mentioned Beseda, Coleus, 

 Geranium, Centaurea, Mentha, Nicotiana, Bicinus, Fuchsia, Sec. An 

 equal number of check plants were grown under similar conditions, but not 

 supplied with excess of carbonic-acid gas. At the end of the experiment 

 the two lots of plants presented much the same aspect, those grown in 

 excess of gas being more robust than the untreated lot. Many of the 

 plants bloomed, and those growing in excess of gas flowered earlier and 

 more abundantly than those growing in normal air. 



Fuchsias alone did not profit by an excess of gas, but they did not 

 suffer.— G. M. 



Cardiospermum (oleiferous and fodder-plant). By G. 



Papasogli {Bull. B. Soc. Tosc. Ort. 12, Dec. 1903, p. 364).— It 

 belongs to Sapindacece. The calyx consists of four persistent sepals ; the 

 four petals are furnished at the base with four petaloid appendages, united 

 to form a cylinder around the sexual organs ; there are eight stamens ; 

 the trigonous ovary is surmounted by three short styles ; the fruit is 

 composed of three swollen capsules united to form a triangular bladder- 

 like structure ; the seeds, one in each capsule, are globose, smooth, with 

 the hilum marked by a remarkable cordiform spot, hence the generic 

 name of the plant. There are eight species, the greater number being 

 herbaceous : they are indigenous to Asia, Africa, and America. The 

 shoots are, as a rule, weak, mounting upwards by means of tendrils 

 attached to surrounding plants. 



C. vesicarium (C. Halicacabum L.) grows wild in the East Indies 

 and has graceful, glabrvtus shoots, rising under cultivation to three metres 

 in height, and annual ; the leaves are stalked, glabrous and alternate ; 

 the small, white, insignificant flowers occur to ; the number of two or three
