238 ARBORETUM AND FRUTICETUM. PART III. 



it seldom ripens seeds in England (see p. 236.) ; but, as it is dioecious, it is pos- 

 sible that he possessed only the male plant. 



Geography, History, $c. Found in North Am erica, 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 maybe purchased 

 in some nurseries. Price, in London, 1*. 6rf. 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.

 Synanymcs. ^tragfene tritermxta Desf. Hort. Par. 



Spec. Char. Leaves biternate or triternate, smoothish ; leaflets oval, cuneated, 

 three-nerved, acutely trifid. (Don's Mill., i. p. 6.) Flowers white? 1806 

 Height 5 ft. 



Description, History, $c. It does not appear that this species has yet 

 flowered in Europe ; and hence it cannot be positively determined whether it is 

 a Clematis, or an Jtragene. 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. Vit&lba. Leathery-flow. 



ered virgin's bower refers to the remarkably thick texture of the sepals ; the German name is a 



translation of Vidrna.

Spec. Char. Peduncles 1 -flowered. Sepals connivent, thick, acuminated, re- 

 flexed at the apex. Leaves smooth, pinnate ; leaflets entire, 3-lobed, alternate, 

 ovate, acute, floral ones entire. (Don's Mill., i. p. 8.) Flowers purple 

 without, and yellow within. June to August. 1730. Height 12 ft. 

 Variety. C. Stmsu is, in all probability, only a variety of this species, as may 

 be possibly, also, C. reticulata. 

 Description, fyc. This species is striking in 

 the dissimilarity of its flowers to those of moist, 

 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. Viticella ; 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 be under- 

 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, 

 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-green colour.
