the calyx short, cut almost to the bottom into five narrow acute seg- 

 ments: the corolla is pale purple, appearing late in July, and often 

 followed by seeds which ripen in autumn. It is a native of North 

 America, flowering in August and September. 



The second species has white flowers, moderately sweet-scented. 

 It is a native of North America, flowering in July and August. 



The third has upright stalks, of a purplish colour, closely covered 

 with white spots, and about three feet high: the leaves about three 

 inches long, and one broad at their base, ending in acute points. 

 Towards the upper part of the stalks are small branches opposite, 

 each terminated by a small bunch of flowers; but on the top of the 

 principal stalk is a long loose spike of flowers, composed of small 

 bunches from the axils at each joint; each cluster having one com- 

 mon peduncle near an inch long, but the pedicels are short. The 

 flowers are of a bright purple colour, and appear late in July: if 

 the season be temperate, or the soil moist, they continue in beauty 

 a great part of August, but rarely perfect seeds in this climate. It 

 is a native of North America, flowering in August. 



The fourth species has the stalks about a foot high: the leaves 

 narrow-lanceolate, ending in acute points, sessile, a little hairy: the 

 calyx cut into acute segments almost to the bottom : the tube of the 

 corolla slender and pretty long, cut at top into five ovate spreading 

 segments: the flowers light purple, appearing at the end of June, 

 but seldom producing seeds in this climate. It is a native of North 

 America. 



The fifth resembles the sixth, but the stem is three times as high, 

 and somewhat rugged: the leaves wider, and ovate-lanceolate: the 

 corymb consisting of numerous flowers, with several peduncles from 

 the uppermost axils of the leaves, erect, and fastigiate into a sort of 

 corymb of a dark purple colour. It grows naturally in Carolina, 

 flowering from July to September. 



The sixth species has the stalks near a foot and half high, dividing 

 into three or four small branches towards the top, each terminated 

 by a corymb of flowers: the lower leaves opposite, three inches long, 

 and near half an inch broad at the base, ending in long acute points,
