3.— DRACOCEPHALUM SPECIOSUM, Swt. THE BEAUTIFUL DRACOCEPHALUM. 
Synonyme. — Physostegia speciosa, Dec. | Specific Character. — Stem erect, obtusely quadrangular. Leaves 
Engraving. — Sweet’s Brit. Flow. Card., t. 93. I lanceolate, sessile, sharply serrated. 
Description, &c. — Tins very handsome species is the type of the new genus formed by Professor De Candolle, 
which is called Physostegia. The flowers are pinkish, and are disposed in regular panicles. Several stems grow 
from the same root to the height of three or four feet ; and the plant is quite hardy. It should be grown in a 
light rich soil, and it is readily increased by dividing the root. The species is a native of North America ; whence 
it was introduced in 1820. 
4.— DRACOCEPHALUM SIBERICUM, Lin. THE SIBERIAN DRACOCEPHALUM. 
Synonymes. — Nepeta macrantha, Z)ec.,' Cataria montana, Bwa:. 1 Specific Character. — FloAvers in whorls. Leaves lanceolate-cor- 
Engravings. — Bot. Mag,, t. 2185 ; and our fig. 1, in Plate 90. I date, acuminate, serrated, glabrous. 
Description, &c. — This is a fine handsome plant, but with a very disagreeable smell, wdiich has been 
compared, by some botanists, to rancid oil, and by others, to what is called stinking Ilorehound. The taste, 
when chewed, at first resembles that of peppermint, but it afterwards becomes bitter and nauseous. The species 
is a native of Siberia, whence it was introduced in 1760. 
OTHER SPECIES OF DRACOCEPHALUM. 
D. CORDATUM, Nutt. 
Tliis species is a native of North America, whence it was introduced in 1824. It is now frequently called 
Cedronella cordata, from its habit of growth, which is spreading, and yet in distinct whorls, like a little Cedar. 
D. CANARIENSE, lAn. 
This plant is a native of the Canary Isles, whence it was introduced in 1697* Its common English name is, 
the Balm of Gilead, from its fragrance. De Candolle now calls it Cedronella triphylla. 
D. DENTICULATA, Lin. 
This species is now included in the genus Physostegia, together with several others nearly allied to it. They 
are all handsome plants with their flowers disposed in panicles, and well worthy of cultivation in every garden. 
Two other well-known species are now called Piiysostegia imbricata, and P. virginiana. 
There are some other ornamental plants belonging to the order Labiatm ; but they are generally either 
natives of Britain, or too coarse in their habit of growth to deserve a place in a lady’s flower-garden.

VERBENACE.E. 
Character op the Order. — Calyx tubular, persistent, inferior. 
Corolla hypogynous, monopetalous, tubular, deciduous, generally 'with 
an irregular limb. Stamens usually four, didynamous, seldom equal, 
occasionally two. Ovary two or four-celled ; ovules erect or pendu- 
lous, solitary or twin ; style one ; stigma bifid or undivided. Fruit 
nucamentaceous, sometimes berried, composed of two or four nucules 
in a state of adhesion. Seeds erect, or pendulous ; albumen none, or 
in very small quantity ; embryo always erect. {^Lindley). 
Description, &c. — The plants belonging to this order are generally trees and shrubs which require a hot- 
house in British gardens. The largest tree is the Teak tree, which is used in India for building ships. The
