OTHER SPECIES OF THALICTEUM. 
T. CLAVATUM Dec. 
The seed-vessels are inflated, and spread out like a star. It is a native of North America, where it is found 
on sand-hills, near Hudson's Bay. It was introduced in 1820. 
T. CORNUTI Lin.; T. REVOLUTUM Dec. i T. CANADENSIS Cornuti. 
A native of North America, introduced in 1806. The flowers are white, or pale purple ; and the leaflets 
are glaucous beneath, and somewhat revolute at the edges. 
T. ALPINUM Lin. ,- Bot. Mag. t. 2237 ; Eng. Bot. t. 262 j 2ai edit. t. 772. 
A very pretty little plant, with an upright stem, and delicate, feathery, nodding flowers. The leaves are 
very small and roundish, like those of the Columbine. It is a native of hilly places through all the north of 
Europe, and it has also been found wild on the mountains of Scotland and Wales. It is quite hardy, and very 
suitable for rock-work. 
T. PETALOIDEUM Lin. 
The sepals of this species are white, and longer than the stamens ; and, though they soon fall, the filaments 
of the stamens are so much dilated as to look like little flesh-coloured petals vrith a yellow ball (the anther), at 
the tip of each. The seed-vessels are striped, and they have no foot-stalks. The species is a native of the north 
of Asia, and it was introduced in 1799. There are many other species of Thalictrum ; but they are seldom seen 
in British gardens. 
GENUS III. 
HEPATICA Dec. THE HEPATICA OR LIVERWORT. 
Lin. Syst. POLYANDRIA POLYGYNIA. 
scries. Stamens and ovaries numerous. Carpels tailless. Leaves 
evergreen, three or five lobcd. 
GiENKBic Chahacter. — Involucre of three entire leaves in the form 
of a calyx close to the flower. Petals wanting in the single flowers. 
Calyx of six to nine petal-like coloured sepals disposed in two or three 
Description, &c. — The European Hepaticas are so well known in every garden, that I need only remind my 
readers that they are dwarf evergreen plants with three-lobed leaves, and very pretty flowers, which are either 
bright blue, bright pink, or white, but never yellow. Like the Clematis, the single Hepaticas have no petals, 
the coloured part of the flower being only a calyx, while that part which looks like a calyx is the involucre ; it 
being separated from the flower by a small portion of the stem, which is never the case with the true calyx. 
The American Hepaticas are probably only varieties of H. triloba. The name of Hepatica signifies belonging to 
the liver, and the English name of the plant is Liverwort, but why these are applied seems doubtful.
