According to Hortus Keweusis, the Ameritan Atrageue was introduced to English 

 gardens by Messrs. Loddiges, in the year l79t. It is the earliest flowering species, but, as 

 the flowers are produced before the foliage, it is less adapted than some others for garden 

 decoration. In its native haunts, in the rocky and bushy woods, it is an agreeable surprise 

 to the botanist to find its charming blossoms among the withered leaves in the early season 

 of spring flowers. 



2. — Clematis Virginiana, Limmus. 



Stem shrubby, climbing. Leaves opposite, petioles twisted and clasping as tendrils, 

 leaflets three, stalked, ovate or somewhat cordate, acute, lobed, and coarsely toothed. Ped- 

 uncles opposite, each bearing a large panicle or cluster of numerous flowers. Sepals four, 

 rather large, petal old. Petals absent. A climber, ten or twelve feet high, clinging to 

 bushes and small trees for support. Flowers white, fragrant. The plant is very conspic- 

 uous in the fall season, as the leafless stems with their numerous clusters of plume-tailed 

 achenes form large feathery wreaths. The leaflets are always prominently toothed, some- 

 times almost lobed, never entire, as they sometimes are in C. Vitalba, of Europe, and 

 constantly in several Indian species. Very variable in length aud breadth and di^'^ision 

 of leaflets.
