Annual. July — September. 



An elegant little plant, varying in height from one inch to 4 or 5, 

 with a square, downy, leafy stem, either simple or branched. 

 Leaves ^ or | an inch long, almost entirely opposite, ovate or 

 heart-shaped, downy, strongly ribbed and furrowed, with sharp 

 tooth-lilce serratures. FL axillary, solitary, very abundant, in- 

 odorous, but remarkable for their brilliant variegated aspect, on 

 which account, it seems, the plant became celebrated as good 

 for weak eyes. The corolla varies much in size as well as co- 

 lour, being commonly white with deep purple streaks, and a 

 yellowish palate ; the anthers violet. On the mountains of 

 Scotland there is a more slender variety, with smaller but more 

 richly tinted blossoms ; on the Alps a dwarf, large-flowered, 

 more purple variety is common. The seeds are few, somewhat 

 angular, thin at the edges, strongly striated, or furrowed, at the 

 sides.
