formation too late in the autumn of 1S3.5, to be able to examine the plant, so as to determine any 

 thing certain respecting its species. Possibly, it may be a new species ; but we think it more pro- 

 bable, from the leaves of a plant in our own garden, also raised from the seeds we brought from 

 Carlsrahe, which has not yet flowered, that it is nothing more than Wistana frutescens. 



App. I. Siiffi'idicose hardy or half-hardy Species ofYhaseblece. 



ht/pinus arboreus Sims {Bot. Mag., 



t. 6ilS , and out Jig. S61.], the tree 



lupine, is somewhat shrubby, and, as 



a standard, will grow to the height 

 361 of fi ft. Its native country is un- 

 known ; but it has been in cultiva. 



tion in British gardens since 1793 ; 



and it produces its pale yellow flow- 

 ers in July and August. There is 



a large plant of it, trained against a 



wall, in the garden of the London 



Horticultural Society; but, though 



it grows as high as the wall, it cannot 



be considered as truly ligneous; and 



it is rather tender. Flowers fragrant. 

 L. multifloriis Desrous., with azure 



blue flowers ; "L.dthifrons Benth. {B. 



Rcg.,t. 164'-'.), ashrubby Californian 



species, with deep blue flowers; L. \

L. versicolor Swt. Fl.-Gard., 2d. ser. 



t. 12. ; L. pulc/ic/liis Swt. Fl.-Gard., 



2d. ser., t. 67. ; are all technically 



considered somewhat suftVuticose, 



and will grow to the height of from 



3 ft. to 6 ft. when trained against 

 a wall lasting 2 or 3 years, if not dcjitroycd during winter by severe frost, i h 

 other species described in Don's Miller, bearing the same general character, but 

 not yet been introduced. 



App. II. Half-hardy Species of Vhaseblece, 



Dilichos lignosus L. {Sm:th Siiic, t 21.) is a ligneous climber, with rose-coloured flowers, having a 

 purplish keel, which is tolerably hardy : it has been an inhabitant of our green-houses since 1776, 

 and flowers in July and August , ,„ , - . , . . , , 



Pacht/rhizns trilobus Dec, Dolichos trilobus Lour., is a twninig shrub, a native of China and 

 CochinlChina, where it is cultivated for the tubers of its roots, which are cylindrical, being about 2 ft 

 long and are boiled and eaten 1)V the natives, in the .same manner as yams are in the West Indies 

 The'flowers are of a bright purple, with a yellow spot in the centre of the standard. This species 

 has not yet been introduced. 



Mucilna macrocdrpa Wall. [PI. As. 

 Bar., 1. p. 41. t. 47., and our Jig. 363.) 

 is a twining shrub, a native of Nepal, 

 on the mountains. The flowers are 

 party-coloured, the standard green, 

 the wings purple, and the keel brown. 

 The legumes are very large, as are 

 the racemes of flowers. It h.is not 

 yet been introduced, but, when it is, 

 it will probably be found half-hardy 

 or hardy. 



Erythrina Crlsta-gtUli L. (Smith 

 Exot. Bot.,2. p. 95. ; Swi. Fl.-Gard., 

 p. 214.), the coral tree, is a splendid 

 plant, a native of Brazil, where it 

 grows to the height of 20 ft. In Bri- 

 tish gardens, it will grow at the base 

 of a wall, with a little protection dur. 

 ing winter, and produce its bright deep 

 scarlet flowers from May to July. 

 E. \aurifdlia Jacq., the E. Crista-galli 

 of Bot. Beg., t. 313., is considered by 

 some as a species ; and by others as a 

 variety of E. Crista-galli. It pro- 

 duces its rich but dull crimson flowers 

 from July to September. No con- 

 servative wall ought to be without 

 these plants, since they may be easily 

 protected at the root by a little straw ; 

 and, even if killed down every year, 

 they will produce shoots, which will 

 terminate in long spikes of coral-like 

 flowers every season. They require 

 a deep sandy soil, somewhat rich ; and 

 are propagated by cuttings of the 

 shoots, or division of the root. There 

 are some other green-house species, 

 not yet introduced, which are probably equally hardy with the above; and, probably, many of the 

 tove species would stand out with some protection.
