672 ARBORETUM ET FRUTICETUM BRITANNICUM. 
all respects closely resembled a catalpa. It is readily propagated by 
cuttings of the roots or shoots; flowers vigorously in any common soil, 
tolerably dry, and will doubtless speedily become as common as the catalpa 
throughout Europe. Horticultural Society’s Garden. 
Orver LV. LABIA‘CE. 
Orb. Cuan. Calyx tubular, persistent, 5-cleft or 5—10-toothed, regular, or hi- 
labiate. Corol/a tubular, bilabiate ; the upper lip undivided or bifid, and the 
lower one trifid. Stamens 4, didynamous, 2 of which are often sterile, inserted 
under the sinuses of the lower lip. odes of anthers usually divaricated. 
Ovaria 4, naked, seated on a glandular disk, and connected with the base 
of the style. Stigmabifid. Achenia 4, or fewer. Albumen wanting, or sparing. 
— The opposite leaves, free 4-lobed ovarium, bilabiate corolla, and 
didynamous stamens distinguish this order from Boraginee ; and the 4-lobed 
ovarium separates it from Verbenaceze and Acanthacer, &c. (G. Don.) 
Leaves simple, alternate, exstipulate, evergreen ; small, crowded. Flowers 
axillary or terminal. — Low shrubs, for the most part so small as to be 
treated as herbaceous plants ; natives chiefly of the South of Europe. 
Though there are a number of genera belonging to this order containing 
species which are technically ligneous, yet there are none that can popularly 
be considered as shrubs fit for an arboretum, with the exception of Phlomis 
fruticdsa, Rosmarinus officinhlis, Lavandula Spica, and Salvia officinalis ; 
these plants are so well known, that we consider it unnecessary to do more 
than give figures of them, with the following slight notices : — 
Phlomis fruticdsa L (N. Du Ham., 6. t. 40.; Bot. 
Mag,., t. 1843. ; and our jig. 1309.), Jerusalem Sage, 
is a native of Spain, with yellow flowers, appear- 
ing in June and July. This is a greyish evergreen 
shrub, growing 4 or 5 feet high, and, in dry soils, 
enduring 10 or 12 years. The flowers are pro- 
duced in large whorls, and have a very conspicuous 
appearance. The plant well merits 
a place in collections, on account 
of the remarkable appearance of 
its foliage, independently altogether 
of its flowers. 
Rosmarinus officindlis L. (Fl 
Grec., 1. t. 14.; and our jig. 1310.) 
is a well-known evergreen shrub, 
a native of the South of Europe, 
which has been an inhabitant of 
our gardens since 1548. There 
are plants of it in different gardens in the neighbourhood 
of London, which, as bushes in the open border, in 5 or 6 
years have attained the height of as many feet, and breadth 
in proportion; thus forming very handsome evergreen 
bushes. As the plant flowers from January to April, it 
forms, when so treated, a very desirable garden ornament. 
There are, also, a variety with.the leaves variegated with 
gold colour, and a silvery-leaved variety; but these are 
often rither weaker, and more dwarf, than the species. 
Lavandula Spica L. (N. Du Hamn., 3. t. 42.; and our fig. 7 
1311.),the common Lavender, is a well-known fragrant shrub, ~ 
a native of the South of Europe and North of Africa, which 
like the rosemary, has been long an inhabitant of British gar- 4 
dens. In deep, dry, calcareous soils, it will grow tothe height 1310. a. omicinaiis.
