Climbing Dielytra. PI. cl. 
Cult. A pretty genus of perennial herbaceous plants. They 
thrive best in a light rich soil, and are easily increased by divid- 
ing the plants at the roots or by seeds. The D. scandens beng 
an annual plant, will only require to be sown in the open border, 
or to be raised on a hot-bed, and afterwards planted out.
