Description, &c.— A very pretty little plant, with pink flowers, looking very much like a kind of Lychnis 
or Silene. It is a native of the Levant, and was introduced in 1713. As it seeds freely and will grow in any 
soil and situation, it has kept its place in gardens, while much handsomer flowers have fallen out of cultivation. 
There are several other annual species, but this is the only kind grown in British gardens. The name of Knautia 
was given to this genus in honour of Dr. Knaut, a Saxon physician, residing at Halle, who died in 1694.
