Lychnis dioica

Isol. from the roots of Silene inflata and from Lychnis dioica. 

Isol. from roots of Lychnis dioica. Occurs in vegetative parts of all species of Caryophyllaceae tested, [ajo +153.5 (c, 0.5 in H2O). 

The pistil is the last of the floral structures to be differentiated during flower formation. In some dioecious species, such as Lychnis dioica, pistil initiation is linked to the presence of a sex chromosome (Westergaard 1958). In many species, however, sexual expression is more subject to modification by environmental factors acting on metabolic processes. This aspect has been studied frequently in monoecious members of the Cucurbitaceae. In these species, as in other monoecious types, light and temperature are particularly potent factors influencing the production of stamens and/or pistils.
