MAJOR CONVOLVULUS. Ill 



collected by Mr. Samuel Richardson, in the province of 

 Gruanaxuato, in Mexico, and were sent over to Mr. Powles, 

 of Stamford Hill, who liberally distributed them. 



This fine plant has purple-tinted branches, large cor- 

 date pale green leaves, and axillary clusters of flowers, 

 which are most elegantly wreathed in spiral folds of red 

 and white while in bud, but finally open to flowers that are 

 five-lobed, and of a clear pale blue colour, sometimes striped 

 with white. Being raised from seed, and sown in February 

 or March, and carefully grown on in a warm house, the 

 plants may be put out in June in a warm, sheltered 

 situation, and soon after will begin to show their lovely 

 flowers. 



The minor convolvulus (already figured and described : 

 Vol. IV., p. 61) is known as Convolvulus minor and 

 Convolvulus tricolor, the three-coloured convolvulus. This 

 is truly a hardy annual, that may be sown in autumn 

 to stand the winter, or with other annuals in the spring. 

 It forms a beautiful bed when in a sunny position on the 

 north or west side of a house within view from the win- 

 dows. The fresh flo-wers that oj)en with the morning will 

 all turn their faces to the south or east, and thus will be 

 seen to peculiar advantage. The combinations of blue, 

 yellow, and white in the flowers afford a rare lesson in 

 colour. There are many varieties, and mixtures are gene- 

 rally preferred. But the finest form is undoubtedly the 

 dark purple ; it is truly sumptuous in colour. 



A sweet rockery plant is the Mauritanian convolvulus 

 (C. Mauritanicus) , of dwarf habit, producing in summer 

 lovely light blue flowers. It is not quite hardy, and must, 

 therefore, be wintered with other tender bedding plants 

 under glass, and planted out again in summer. It is
