CHAP. XV. 
OF THE HARDY AND HALF-HARDY SUFFRUTICOSE PLANTS OF THE 
ORDER LINA‘CEX. 
Tuts order is included in our catalogue for the sake of the tree 
flax, Linum arbireum L. (Bot. Mag., t. 234., and our jig. 86.) It is 
a native of Candia and Italy, on the mountains, and forms a neat 
little evergreen bush in dry soils, in warm situations in the neigh- 
bourhood of London, requiring little or no protection, except during 
the most severe winters. The largest plants which we have seen 
of it were in a sandy border in the garden at Nonsuch Park, in 
Surrey. They were about 2 ft. high, and 3 ft. broad, and they pro- 
duced their fine large yellow flowers from May to September; in 
the same situation ripening seeds, from which, or from cuttings, 
they are readily propagated. Linum tatricum W., from Tauria, 
which grows to the height of 12 ft., and L. salsoléides Lam., with 
pink flowers, are equally hardy with L. arboreum ; and all three 
should be included in every complete arboretum and fruticetum. 
L. suffruticdsum, from Spain, an old inhabitant of our green-houses, 
with pink flowers, is, in all probability, as hardy as the others. 
CHAP. XVI. 
OF THE HARDY AND HALF-HARDY LIGNEOUS PLANTS OF THE 
ORDER MALVA‘CEX. 
DIsTIncTIVE Characteristics. Thalamiflorous. (H. B.) Calyx with a valvate 
zestivation, mostly with an involucre. Stamens with the filaments monadel- 
hous, and the anthers l-celled. Pubescence starry. (Lind. Introd. to N. 8.) 
he hardy ligneous species of this order are few, but splendid; the Hibiscus 
syriacus, and its different varieties, being among the most ornamental of flow- 
ering shrubs. Chemically, all the species abound in a nutritive mucilage ; 
and, medicinally, they are emollient. The fibrous threads of the inner bark 
may, in most.of the species, when properly prepared, be manufactured into 
cordage or cloth. The genera containing hardy or half-hardy species are 
two: Lavdteraand Hibiscus ; the distinctive characters of which are: — 
Lava’rer4 L. Carpels capsular, 1-seeded, disposed into “a ring around the 
axis. 
Hisrscus L. Carpels joined into a 5-celled capsule.

Monadélphia Polyandria.

Synonymes. The Tree Mallow ; Lavateére, Fr. and Ger. 
Gen. Char., &c. Calyx 5-cleft, girded by a 3- or 5-cleft involucel ; its leaflets being joined as far as 
the middle. Carpels capsular, 1-seeded, disposed ‘into a ring around the axis, which is variously 
’ dilated abovethe fruit. (Dec. Prod.,i. p. 438.) The half-hardy ligneous species are L. mar{tima, 
triloba, subovata, and africana.
