1306 ARBORETUM AND FRUTICETUM. PART III. 
cinnamon tree, is a native of the Island of Ceylon, and other parts of the East ; andit has been in- 
troduced into South America, and the Isle of France, where it is cultivated for the bark, It is com- 
monly considered as a stove plant, but it has ripened seeds in the conservatory of M. Boursault, at 
Paris, from which young plants have been raised, in 1827, 1828, and 1829, and these plants have stood 
the winter in the open air there for several years, with very little protection. It well deserves a trial, 
therefore, against a conservative wall, in British gardens. 
C. Cassia D, Don; Latrus Cassia L.; L. Cinnamdmum Bot. Rep.; Pérsea Cassia Spr.; the 
Wild Cinnamon, Bot. Rep., t.596., which is a native of Ceylon, where it grows tothe height of 50 ft. or 
60 ft., with large spreading branches, is thought to be nothing more than C. vérum in a wild state. 
Other ligneous plants belonging to this order, natives of Japan, Mexico, the Cape of Good Hope, 
and of New South Wales, and usually kept in green-houses, will be found enumerated in our Hortus 
Britannicus. Most of them, we have na doubt, could make a much better appearance against a flued 
conservative wall, than ever they can do in a house.

OF THE HALF-HARDY LIGNEOUS PLANTS BELONGING TO THE 
2 ORDER PROTEA‘CE®. 
ALL the plants of this order are ligneous; and, with very few exceptions, are natives of Australia, 
and the Cape of Good Hope. Many species have been introduced, belonging to upwards of 30 
genera; and, doubtless, there are a great number of these, particularly the natives of New Holland, 
which would stand the winters of the climate of London against a conservative wali. 
Bénksia littoralis R.‘Br. is a native of New Holland, where it forms 
a bush 8 ft. high, A plant stood against a wall in the Horticultural 
oe Garden, from 1832 till it was killed by the severe spring of 
1 
B. oblongifolia Cav., Bot. Cab., 241., stood out with us at Bayswater 
for four years, but was killed in the spring of 1836. 
Grevillea_rosmarinifolia Cun. (fig. 1176.) is a very elegant plant, a 
native of New South Wales, where it grows to the height of 4 ft. or 
5ft. Aplant has stood out in front of the stove at Kew, since 1826, 
flowering freely every year. 
G. acuminata R. Br. ( figs. 1177, 1178.) is also a native of New South 
Wales, and is considered equally hardy with G. rosmarinifolia. 
Hakea aciculdris R, Br., Vent. Malm., 3.; H. swavéolens R. Br. ; 
and H. pugioniférmis R. Br., Bot. Cab., 353., and our fig.1179. ; have 
stood out in the Horticultural Society’s Garden since 1832. 
It is probable that most of the species belonging to this order are 
equally hardy with those above enumerated; and we should have 
no hesitation in asserting that, against a flued wall, with straw hur- 
dles to be set against it during severe weather, and taken off for an 
hour or more every fine day, all the Protedcee might be exhibited in 
the climate of London in greater vigour and beauty than they are in 
their native country. This may be thought a bold assertion; but, as 
it holds good in the case of Erica and Pelargonium, we see no reason 
why, if the same care were applied, the same should not follow in the 
case of all the plants of this very interesting order.
