The inflated calyx has twenty main veins and many cross veins creating a reticulate pattern.  The petals have a claw-limb configuration and the distal portion of the claw is dilated.  Note the three styles.

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.
