obovata, both stove plants, and natives of Egypt ; though the latter, which is called Italian senna, is 
found about Rome. : 
Chamef tstula (from chamai, ground, and fistula, a pipe ; on account of 
the species being comparatively dwarf, and of its cylindrical pods) Don’s 
Mill., ii. p. 451., is a genus separated from Cassia, and consists of 27 species. 
C. corymbosa G. Don, Cassia corymbosa Lam. (Dict., i. p. 644., Bot. Mag., 
‘t. 633., 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. 
Schotia stipulgta 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. t.15. f.4., and 
our fig. 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 
Schdtéa, are produced occasionally on the old wood, though chiefly at 
the extremity of the young spring and summer shoots; a habit which 
ought always to be kept in view in pruning the plants. 


App. I. Other half-hardy ligneous Species of the Order 
Leguminacee. 
There being no truly hardy species belonging to the tribes Dalbergiée, Mimdsex, and Gedffrew of 
this order, we are necessarily obliged to devote a separate appendix to them. 
§i. Dalbergice. 
Sect. Char. The species are for the most part climbing shrubs, with impari-pinnate leaves, rarcly, 
but sometimes, pinnately-trifoliolate, or simple. (Don’s Milz., ii. p. 373.) 
Deérris sertcea G. Don is a Nepal shrub, with small yellow flowers, and leaves covered with a silky 
pubescence, OD. ¢rifolidta Lour. is a climbing shrub, a native of China, not yet introduced, 
Pterocarpus peltarius Dec, Leg. Mém., 10. t. 57, f.2., is a tree, a native he Cape of Good Hope , 
not yet introduced. 
§ii. Mimosee. 
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 Miil., ii. p. 381.) 
_ Prosopis L. is a genus of Indian or American trees, of which scarcely any species have been 
introduced ; but P. glanduldsa Torrey (Ann. Lyc., 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. Siliqgudstruwm Dec. (Don’s Mill., ii. p. 400.), which has stood 
ara the wall in ‘the Horticultural Society’s Garden, with very little protection, since the year 
Lagonychium Stephaniinum Bich. Supp., Acacia Stephanidna Bieb. Fl. Taur., Mimdsa 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.
