Description

This biennial or perennial herb was not higher than 12 cm and had a glabrous stem. The light green leaves were thick and fleshy. The stipule was cut and had an entire central lobe. The relatively large flowers were zygomorphic. The petals were light violet. The spur was with six to seven millimetres larger than the calyx. The flowering period was from May to June.

Extinction

The Cry violet occurred in strongly restricted limestone outcrops in the region of Cry southeast of Tonnerre in the French department Yonne. Due to the habitat destruction because of the limestone quarrying and due to overexploitation by plant collectors it was thought to be extinct in the wild by 1930.[1] This plant might have survived in cultivation until 1950.[2]

gollark: Well then use it??!??!?!?!
gollark: What?
