obovata, both stove plants, and natives of Egypt ; though the latter, which is called Italian senna, is 

 found about Rome. 



Chamcef istula (from chamai, ground, and fistula, a pipe ; on account of 

 the species being comparatively dwarf, and of its cylindrical pods) Don' 

 Mill., ii. p. 451., is a genus separated from Cassia, and consists of 27 species. 

 C. corymbbsa G. Don, Cassia corymbbsa Lam. {Diet., i. p. (144., Bot. Mag., 

 t. 63a, and our fig. 370.), affords a very good example of the genus. It is 

 a native of Buenos Ayres, where it grows to the height of 8 ft. or 10 ft. ; 

 and it would form a very handsome plant against a conservative wall. 



Sckbtia. stipuldta Ait. and S. alata Thunb. are Cape shrubs, with crim- 

 son flowers, now kept in stoves and green-houses, but well deserving trial 

 against a conservative wall. S. latifolia Jacq. (Fragm., 23. 1. 15. f. 4., and 

 oury^. 369.) which was introduced in 1816, and grows to the height of 6 ft, 

 will give an idea of the general appearance of plants of this genus. In their 

 native country, the species of this genus are of slow growth, and they 

 form bushes rather than trees. Mr. Bowie observes that planting them 

 under the shade of taller-growing shrubs, or of trees, will draw them 

 up, and, at the same time, not injure them, or preclude them from display- 

 ing their beautiful flowers. These flowers, in all the varied species of 

 Schbto, are produced occasionally on the old wood, though chiefly at 

 the extremity of the young spring and summer shoots ; a habit which 

 ought ahvays'to be kept in view in pruning the plants. 



App. I. Other half-hardy ligneous Species of the Order 

 Legumindcece. 



There being no truly hardy species belonging to the tribes Dalberg?'e<z?, Mimbsea?, and Geoffrey of 

 this order, we are necessarily obliged to devote a separate appendix to them. 



§ i. jDalberg'iess. 



Sect. Char. The species are for the most part climbing shrubs, with impari-pinnate leaves, rarely, 

 but sometimes, pinnately-trifoliolate, or simple. {Don's Mill., ii. p. 373.) 



De'rris sericea G. Don is a Nepal shrub, with small yellow flowers, and leaves covered with a silky- 

 pubescence. D. trifoliata Lour, is a climbing shrub, a native of China, not yet introduced. 



Pterocdrpus peltarius Dec. Leg. M£m., 10. t. 57. f. 2 , is a tree, a native of the Cape of Good Hope , 

 not yet introduced. 



§ ii. Mimbsece. 



Sect. Char. Flowers regular, usually polygamous, rarely all hermaphrodite. Stamens inserted with 



the petals, free or monadelphous, equal in number to the petals, or forming a multiple of that 



number. Leaves abruptly pinnate, or abruptly bipinnate. (Don's Mill., ii. p. 381.) 



Frosdpis L. is a genus of Indian or American trees, of which scarcely any species have been 



introduced ; but P. glanduldsa Torrey (Ann. Lye., 2. p. 192. t. 2.) is a native of North America, on 



the Canadian river, where it is called the algaroba tree. There is a plant belonging to this genus, a 



native of Chili, and, possibly, hardy, P. Siliqudstrum Dec. (Don's Mill., ii. p. 400.), which has stood 



against the wall in '.the Horticultural Society's Garden, with very little protection, since the year 



1832. 



Lagonpchium Stephariinnum Bleb. Stipp., Acacia Stephaiwina Bieb. Fl. Taur., Mimbsa micrantha 

 Vahl, (Breyn. Cent., 1. t. 56. f. 4.) is a small shrub, with scattered prickles, and bipinnate leaves, a 

 native of the arid plains between Caucasus and the Caspian Sea; and of Persia, between Mossul 

 and Bagdad. It was introduced in 1816, grows to the height of 2 ft., and flowers in July and August.
