more hardy than the European species. In Britain, it is propagated by im- 

 ported seeds, and is considered more tender than C. 5'iliquastrum ; but it would 

 probably be rendered more hardy by being grafted on that species. 



Statistics. In the environs of London, it is seldom found higher than 10 ft. or 12 ft. ; and then it 

 has more the character of a bush than of a tree; but on the Continent there are some good speci- 

 mens. In France, at Paris, in the Jardin des Plantes, .W years planted, it is Jfift. high, the diameter 

 of the trunk, 10 in., and of the head 20 ft ; in the Rue (Crenelle, in Paris, in the garden of the house 

 No. 122., as we are informed by Mr. Blaikie, there is a tree 40 ft. high, with a trunk 1^ ft. in diameter. 

 In Saxony, at Worlitz, 2j ye.ars planted, it is 10 ft. high. In Austria, at Vienna, in the University 

 Botanic Garden, 9 years planted, it is 16 ft. high. In Italy, at Monza, 24 years planted, it is 13 ft. high. 



Cnimnercinl Statistics. Plants, in the London nurseries, are \s. 6d. each, and 

 seeds 1.?. G(/. per ounce; at Bolhvyller, plants are 1 franc each ; antl at New 

 York, the plants of the species are from 25 to 37^ cents each, and of " Fore- 

 man's new variety," 37 cents each.

Ctvsalpima Ail. is a genus of beautiful flowering trees and shrubs, most of the species of which are 

 natives of tropical countries, and which, in Kngland, are generally kept in stoves ; but there is one 

 species, C. Lebbcko/rffs Dec., a native of China, which, if once introduced, would probably be a valu- 

 able addition to a conservative wall. 



Cadia varia I/Herit. {Don's Mill, 2. p. 435.) is a shrub, a native of Arabia Felix, with impari-pin- 

 nate leaves ; and flowers, at first white, but, as they fade, becoming rose-coloured. It was introduced 

 in 1777, and might be tried against a wall. 



Zucctign\A Cav. is a Chilian genus, of which the species are probably half-hardy. Z. piincliita Cav. 

 Icon., 5. p. 2. 1 403., has abruptly pinnate leaves, and saHVon-coloured' flowers. It grows to the height 

 of 4 a or.'; ft 

 Ceratduia Silligua L. {Bot. Rep. ,t 5i~., and our figs. SG'), 36t> ) is a very interesting tree, a native of 

 rx thesoiithofEuroiK-, particularly Spain ; it is also found in Mau- 



V.-d[^^«Tn->. ritania and the Levant. The leaves are .ibruptly pinnate; the 



3G5 .»-''■: '"— leaflets oval, obtuse, flat, coriaceous, and of a shining dark 



•( " ■ green. The flowers are polygamous or dioecious, and without 



-] petals. The tree grows to the height of from 30 ft. to 50 ft In 

 y the south of Kurojie, when the fruit is per- 

 fectly ripe, the pulp contained in the po<ls is 

 eaten by men, the seeds by horses, and the

 The husks are thought to have been the dry 

 and wretched food that the Prodigal Son was 

 driven to long for, in the last stage of his misery and starvation. The plant has been in British 

 green-houses since 1.770; and the male plant has flowered every autumn, for many years past, in 

 the Mile End Nursery. This tree will very nearly stand the open air in the vicinity of Paris ; and, 

 if planted against a wall in the neighbourhood of London, it would probably stand with very little 

 protection. lU fine large coriaceous dark green foliage ought to be a strong inducement for every 

 one who has an opportunity to give it a trial. As a fruit tree, it may merit introduction into Austra- 

 lia, for which purpose the seeds can be rcndilv procured from Spain. It is remarked in the Kouvcau 

 Dii Hamcl, 1. p. 25,5., that, when the ripe fruit has been eaten by oxen or mules, the seeds which 

 have passed through them without digestion vegetate much sooner than when they are sown in the 

 natural manner. The tree is of slow growth, and the wood is extremely hard and durable. Its roots 

 attach themselves so firmly to the soil, that, in Spain, even in the most 

 exposed situations, in the gullies of mountains for example, the tree has 

 never been known to be blown down by the wind, so as to be torn up by 

 the roots, though large branches have been broken off it by storms. 



Castanosp^rmum nH,s7r"/<? Cunningham [Hook. Bot. Misc., 1. p. 241. t 51. 

 and t 52.) is a New Holland tree, growing to the height of 40 ft. or 60 ft., 

 the legumes of which are produced from two years' old wood ; and they 

 contain seeds as large as Spanish chestnuts, which are eaten roasted by 

 the natives about Botany Bay. As one of the few New Holland trees 

 which produce edible fruit, it is highly interesting, and well deserves a 

 place against the conservative wall, adjoining Ceratfinia. 



Cdssin L. is a genus consisting chiefly of tropical shrubs or herbs, with 

 abruptly pinnate leaves, and vellnw flowers, most of which require to be 

 kept in the stove; hut C. Biircl(ii/ma Swt. (Ft. Austr., t. 32., and our 

 fig. .367.) and C. nu.f^ra//.? Hook. [Bot. Mag., t 2676., and our y/y^. 36,8.) 

 are natives of New Holland, growing to the height of 3 ft or 4 It, and 

 producing their fine showy yellow blossoms from June to August The 

 senna of the druggists is produced from the leaves of two species of this genus, C. lar.ceolata and O
