C. scopdrius L., and C. fléridus L., are natives of the Canaries, where they form trailing shrubs , 
from 1 ft. to 3 ft. in height ; and they might probably be treated as half-hardy.

OF THE HARDY AND HALF-HARDY LIGNEOUS PLANTS BELONGING 
TO THE ORDER BORAGINA‘CER. 
2 Lithospérmum fruticosum L. (Garid. Aix., p. 68. t. 15.) is a native of the south of Europe and 
north of Africa, where it forms a shrub from | ft. to 3ft. high, producing its blue flowers in May 
and June. It was introduced in 1683, but is not common in collections. ; 
2 L. fruticdsum mijus Lehm. ; L. rosmarinifdlium Tenore, Bot. Reg., t. 1736. ; and our fig. 1101. 
is anative of Naples, and on the mountains of the Grecian Archipelago. 
Det ollie gly ¢. L. prostratum Lois. Fl, Gall., 1. p. 
rls WAL y 105, t. 4., isa prostrate suffruticose plant, 
UC | anative of France. Introduced in 1825. 
Bi SAN The corolla is of a bluish purple; and 
a) the whole plant is pilose and canescent. . 
It is, in all probability, only a variety of 
L. fruticdsum. 
E‘chium L. There are some species of 
this genus natives of Teneriffe, the Ca- 
nary Islands, and Madeira, on rocks. 
They have mostly splendid blue or white 
flowers, and some of them, such as £. gi- 
gantéum, grow as high as 10 ft. On dry 
rockwork, in a warm sheltered situation, 
we have no doubt they would all prove 
half-hardy. £. candicans L., Bot. Reg., 
and t. 44., our fig. 1102.,is one of the most 
common species in British green-houses. 
It is anative of Madeira, on high rocks ; 
was introduced in 1777; grows to the 
height of from 2 tft. to 4 ft. ; and produces 
its blue, campanulate flowers in May and 
June. 
Heliotropium peruviinum L., H. p. 
hgbridum Hort. Brit., and H. corym- 
bosum Ruiz et Pav., Bot. Mag., t. 1609., 
+ 1101 are Peruvian under-shrubs, well known 
for their fragrant flowers, and on that account introduced into every flower-garden. Plants are raised by 
cuttings early in spring ; and, being turned out into a bed of rich light soil, they flower freely all the 
summer, till they are destroyed by frost. Two or three stock plants should be kept through the 
winter, in the green-house or pit, to be ready to be placed in a hot-bed or stove, in order to furnish 
abundance of cuttings in spring. (See the mode of treating 2dsa {indica by Mr. Elles, noticed p. 801.) 
CHAP. LXXXIII. 
OF THE HALF-HARDY LIGNEOUS PLANTS OF THE ORDER CORDIA‘CEZ, 
Ehrétia serrata Roxb. Cor., 1.t. 55., and ourf¢g. 1103., is a 
low tree, a native of the East Indies and China. Introduced 1103 
in 1795, and generally kept in stoves; but a plant has stood, - 
since 1830, against a wall in the Horticultural Society’s Gar- 
den; where it grows rapidly, flowers freely, and appears 
ue hardy. A plant, as a standard, in the open garden, at 
essrs. Loddiges’s, has the shoots killed down every year to 
within 1ft. of the ground; but the stool sends out fresh Bye | 
shoots every spring, which generally attain the height of 3 ft. 4 
or 4ft. in the course of the summer, and makea fine appear- Iwene 
ance, from the large size of their leaves. The circumstance 
of a plant like this, a native of the East Indies, and so long 
considered as a stove plant in England, having lived in the 
open garden for several years; and, against a wall, having not 
only lived, but flowered freely; ought to be a great encourage- 
ment to cultivators to try almost every kind of plant, what- 
ever be its native country, in the open air, when they have 
an opportunity. Wedo not recommend the trial of scarce 
and valuable stove plants; and from the palms, Orchidacezx, 
and other endogenous orders or tribes, perhaps little is to 
be hoped for in the way of acclimatisation: but all her- 
baceous plants that die down annually to the ground, and 
all exogenous ligneous plants, deserve a trial, when a plant 
can be spared without injuring the collection to which it 
belongs. Uf, after a thousand trials, one species only should 
have proved sufficiently hardy to endure the open air in our 
climate, the recompense to the cultivator will be ample. 
Let him not forget, in making experiments of this kind, that 
Aticuba japonica was originally treated as a stove plant, and 
Kérrva japé6nica as an inhabitant of the green- house.
