“ Professor Lindley mentions the plant to be annual, and only three or four inches high: in the greenhouse of the Botanical Garden of Glasgow its duration is more than annual, and it attains to about two feet. It is a very charming plant, no less deserving of cultivation for its beauty, than for the singular property of the column of stamens being endowed with a very active irritability, so that if touched with a pin on the out-side when curved, it bounds over to the opposite side of the flower and becomes inverted: this property is observable, in a greater or less degree, in the whole Genus. ”
