238 ARBORETUM AND FRUTICETUM. PART III. 
it seldom ripens seeds in England (see p. 236.) ; but, as it is dicecious, it is pos- 
sible that he possessed only the male plant. 
Geography, History, §c. Found in North America, from Canada to Florida, in 
hedges, on the margins of woods, and on the grassy banks of rivers. It was 
cultivated by Miller in 1767; and, though it is not so ornamental as most of 
the other species, it still finds a place in botanic gardens, and may be purchased 
in some nurseries. Price, in London, Is. 6d. a plant, and 6d. a packet of 
seeds ; at Bolwyller, 3 francs a plant ; and in New York, 25 cents a plant, or 
2 dollars a quart of seeds.

Description, History, §c. Yt does not appear that this species has yet 
flowered in Europe ; and hence it cannot be positively determined whether it is 
a Clématis, or an Atragéne. De Candolle appears to have seen a living plant in 
the Paris Garden; and he notices that it had not there flowered; which is the 
case, also, with the plant in the garden of the London Horticultural Society. It 
is a low feeble-growing plant, and might almost be considered as herbaceous.

Derivation. The derivation of Viorna has been already given under C, Vitaiba. Leathery-flow- 
ered virgin’s bower refers to the remarkably thick texture of the sepals; the German name is a 
translation of Vidrna.

Variety. C. Simsii is, in all probability, only a variety of this species, as may 
be possibly, also, C. reticulata. 
Description, §c. This species is striking in 
the dissimilarity of its flowers to those of most 
other species. They may be compared to large 
pendulous acorns ; but the terminal parts of the 
sepals are curled upward from the terminal part 
of the acorns, and towards its sides. The species 
is (in suitable soil) of vigorous growth, and, exclu- 
sive of its flowers, assimilates to C. Viticélla; but 
its stems and branches are less decidedly ligneous. 
De Candolle has cited from Barton, that the herb 
of this species (by which, perhaps, is to beunder- 
stood the growing parts of it) is intensely acrid. 
The stems are numerous, slender, and round; the 
peduncles of the flower are long, deflexed to- 
wards the tip, rendering the flowers pendulous, (7 
the sepals never open, except at their extreme @ 
ends, which are bent back, giving the whole 
flower a bell shape, but with the mouth of the 
bell narrower than the body. The sepals are of a greenish purple, or reddish 
lilac, on the outside, and of a very pale green within. The stamens scarcely 
emerge from the sepals. The carpels are broad and flat; as they ripen, the 
tail becomes bent in and plumose, and of a brownish-ereen colour.
