xh, Célsia lanata Jac., Bot. Reg., t. 438., and our fig. 
I. 1126., is a suffruticose plant of uncertain origin, but 
with showy yellow flowers, which it produces from 
July to September. It is commonly kept in a frame, 
but would thrive well on conservative rockwork, in a 
favourable situation. 
Capraria lanceolita L.; Freelinia salicifolia Bot. 
Mag., t. 1556. ; is a native of the Cape of Good Hope, 
introduced in 1774. A plant has stood against the wall 
in the Chelsea Botanic Garden for several years; 
and, though it is generally klled down to the ground 
‘ in winter, it has always hitherto sprung up again in 
spring, and made a much finer appearance than it 
could possibly have done in a pot.

against a conservative wall in the south of England. 
1129 If, after perusing what is stated in this work respecting the half-hardy ligneous 
plants of any order or tribe, the reader will turn to the same natural order or tribe 
in our Hort. Brif., he will generally find a number of other species, green-house or stove plants, and 
suffruticose or completely ligneous, from which he may increase his selection for trial in the open air.

OF THE HARDY LIGNEOUS PLANTS OF THE ORDER LABIA‘CER. 
Aumost the whole of the plants of this order, which are technically ligneous 
or suffrnticose, may be more properly treated, in gardens, as herbaceous plants 
than as shrubs; nevertheless, as 
this work would be incomplete 
without noticing them, we shail 
name some of the principal species, 
and refer for the remainder to 
our Hortus Britannicus. The best 
situation for a collection of lig- 
neous Labiacez, is on dry rock-

Saturéja montana L., Fl. Graec. t. 543., and our Jig. 1131., is a well-known 
culinary herb, a native of the south of Europe, which, on dry calcareous soil, 
: will form a neat little evergreen bush, 
from 1ft. to 2ft. in height. S. 
capitita Willd., a native of the Le- 
vant, is equally hardy, and, indeed, 
appears to be only a variety of the 
former. There are, also, some species 
or varieties from Sicily, Candia, and 
the Ionian Islands, which are con- 
sidered as frame plants, and may 
be tried on conservative rockwork. 
Thymus vulgaris L., and our 
Jig. 1132., forms a neat little ever- 
green shrub, when kept in dry cal- 
careous soil, or on rockwork : and 
T. grandifiorus Hort.; T. Masti- 
china L., Black., t. 134.3; isa native 
of Spain, with hoary, hairy calyxes. ~ 
In an arboretum where every single 1133 
DY 4 species or variety is to be exhibited 
g by itself, such a beautiful and fragrant genus as 7hymus 
may have a small cone or hemisphere of rockwork devoted to each species 
or variety. There are some half-hardy species, which might also be tried. 
They are not only beautiful when in flower, but are highly fragrant, and 
attractive to bees. 
Hyssopus officinalis L., and our fig. 1133., forms an undershrub of 2 ft. in
