Silene littorea is a species of flowering plant within the family Caryophyllaceae.[1] The species has the gynodioecy–gynomonoecy sexual system. It is one of the most studied species with this sexual system.[2]

Description

Silene littorea is a low growing annual plant reaching heights of around 15 cm tall.[1][3] The plant is covered in sticky hairs known as trichomes.[3]

Flowers

Silene littorea flowers are about 2 cm in diameter and possess five petals.[3] The species exhibits flower colour polymorphism: with light pink, dark pink and white flowered colour morphs being present within Silene littorea populations.[4] The flowers of Silene lottorea can either be female or hermaphordite.[5] An individual plant can possess any three sexual phenotypes, with plants possessing either female only flowers, hermaphorodite only flowers or even a mix of both.[5]

Distribution

The species is native to Morocco, Portugal, Spain.[6] The population of this species has been observed to be declining in Spain.[7] The species is rare in Gibraltr and restricted to eastern sandy slopes.[3]

Habitat

Silene littorea grows in sandy soils on coastal locations.[3] It can often be found inhabiting coastal sand dunes.[8]

Subspecies

The following subspecies are recognised:[6]

  • Silene littorea adscendens
  • Silene littorea littorea
