formation too late in the autumn of 1835, 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 
Carlsruhe, which has not yet flowered, that it is nothing more than Wistirza frutéscens.

Lupinus arboreus Sims (Bot. Mag., 
t. 628., and our fig. 361.), the tree 
lupine, is somewhat shrubby, and, as 
a standard, will grow to the height 
of 6ft. Its native country is une 
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 Jarge 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.

other species described in Don’s Mil/er, bearing the same general character, but most of which have 
not yet been introduced.

Half-hardy Species of Phasedlee. 
Délichos lignosus L. (Smith Spic., 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. 
Pachyrhizus trélobus Dec., Dolichos trilobus Lour., is a twining shrub, a native of China and 
Cochin-China, where it is cultivated for the tubers of its roots, 
which are cylindrical, being about 2 ft, 
long, and are boiled and eaten by 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. , 
Mucitna macrocdrpa Wall. (Pl. ds. > 
Rar., 1. p. 41. t.47., and our fig. 363.) e 
is a twining shrub, a native of Nepal, 
on the mountains. The flowers are 
party-coloured, the standard green, 
the wings purple, and the keelbrown. 
The legumes are very large, as are 
the racemes of flowers. It has not 
yet been introduced, but, when it is, 
it will probably be found half-hardy 
or hardy. : 
Erythrina Crista-gdlli L. (Smith 
Exot. Bot., 2. p. 95.; Swt. 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. \aurifolia Jacq., the E. Crista-galli 
of Bot. Reg., 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 bya little straw ; 
and, even if kiiled 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, prebably, many of the 
tove species would stand out with some protection.
