223. CLEMATIS. 



CLEMATIS VIRGINIANA. L. Traveller's Joy. Virgin's Bower. 



Leaves trifoliate,; leafets heart-shaped, sublobate- 

 angular, climbing ; flowers dioecious. L. 



A climbing hardy vine. The stem gives off at intervals a pair 

 of opposite petioles, which twine round objects of support, serv- 

 ing the purpose of tendrils; each bears three heart-shaped leafets, 

 which are variously toothed and lobed. Peduncles axillary, 

 bearing cymes of white flowers, which are dioecious, the fertile 

 flowers having imperfect anthers. The most remarkable ap- 

 pearance of this plant is when in fruit; the long feathery tails of 

 the seeds appearing like tufts of wool. Grows in low ground. 

 Very abundant on the banks of the Neponset river, Milton. Au-
