on each side: the stalk rises two feet high; ihey are slender, smooth, 

 and of a light purple colour: the leaves ovate-lanceolate, indented, 

 near two inches long, and three quarters of an inch broad, of a pale 

 green on their under side: the flowers are produced in short bunches 

 from the axils almost the whole length; the lower spikes are an 

 inch long, but the upper ones are almost round : the flowers are of 

 a brimstone colour, and appear late in August. It is a native of 

 Canada. 



The tenth species is remarkable for its red slalk, higher than a 

 man, with very smooth and somewhat fleshy leaves, a little rugged at 

 the edge, continuing the whole winter; it flowers very late, so that 

 in the Northern countries the frost commonly prevents them from 

 opening. It is a native of North America. 



Culture. These plants are all readily increased by slipping or 

 parting the roots, and planting them out in the autumn or winter 

 soon after their stems decay, or very early in the spring before they 

 begin to shoot ; but the former is the better season, in the places 

 where they are to grow: they succeed in almost any soil or situation, 

 and afterwards require only to be kept clean from weeds, and to have 

 the decayed sterns cut down when they begin to decay in the autumn. 

 When they have increased considerably in the roots, they should 

 always be slipped as above. 



In planting out they require much room, as they spread consi- 

 derably. 



They afford considerable variety and ornament in larger borders 

 and clumps.
