Silene noctiflora
 
Night-Flowering Catchfly

Petal and Stamen

Just South of Armit
24-July-2020

Each petal has two appendages at the junction of the claw and the limb.  At each side of this junction is an auricle.

Note that Budd's Flora recognized two related genera - Silene and Lychnis. Today Lychnis is subsumed in a larger Silene. Therefore the answers separating Silene from Lychnis have been removed from the answers leading to the genus and added to the answers leading to the species.
