STNomfME. — Physostegia epeciosa, Dec. 
EvGRAViNo.^Sweet's Brit. Flow. Gard., t. 93. 
Specific Character. — Stem erect, obtusely quadrangular. Leaves 
lanceolate, sessile, sharply serrated. 
Description, &c. — This 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 tha root. The species is a native of North America ; whence 
it was introduced in 1820. 
4.— DRACOCEPHALUM SIBERICUM, Lin. THE SIBERIAN DRACOCEPHALUM. 
Synonymes. — Nepeta Tuacrantha, Dec; Cataria montana, Bux. i Specific Character. — Flowers in whorls. LeaTes lanceolate-cor- 
Engravings. — Bot. Mag., t. 2185 ; and our Jig. 1, in Plate 84. I date, acuminate, serrated, glabrous. 
Description, &c. — ^This is a fine handsome plant, but with a very disagreeable smell, which has been 
compared, by some botanists, to rancid oil, and by others, to what is called stinking Horehound. Tlie 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 DEACOCEPHALUM. 
D. CORDATUM, Null. 
This species is a native of North America, whence it was introduced in 1824. It is now frequently called 
Cedronella cordata. 
D. CANARIENSE, tin. 
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 tripliylla. 
D. DENTICULATA, Liu. 
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 Physostegia imbricata, and P. virginiana. 
There are some other ornamental plants belonging to the order Labiatae ; 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. 
CHAPTER XLI 
VERBENACE^. 
Character of the Order. — Calyx tubular, persistent, inferior. 
Corolla hypogynons, monopetalous, tubular, deciduous, generally with 
an irregular limb. Stamens usually four, didynamous, seldom equal, 
occafiionally two. Ovary two or Sour-celled ; ovules erect or pendu- 
lous, solitary or twin : style one ; stigma bifid or undivided. Fruit 
nucamcntaceoua, 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
