Trojan Snowdrop (Galanthus trojanus)

Troyan snowdrop (Galanthus trojanus) is a perennial, bulbous and endemic plant species belonging to the Amaryllidaceae (Narcissaceae) family. First described to the scientific community in 2002, this species is distinguished from other snowdrop species by its morphological characteristics. Particularly its broad and bright green leaves and the characteristic green markings on the inner tepals form the defining features of the species. With a limited distribution range, the Troyan snowdrop snowdrop is among the critical species of Türkiye’s flora requiring conservation.

The Troyan snowdrop has spherical or egg-shaped bulbs with a diameter of approximately 1.2 to 2.5 cm. The leaves become prominent during the flowering period and typically reach a length of 11 to 23 cm and a width of 1.2 to 2.5 cm. The leaf color is a bright dark green, and the waxy (glaucous) layer found in some other snowdrop species is absent in this species.

When examining the flower structure, the outer tepals measure 18 to 25 mm in length while the inner tepals are 9 to 12 mm long. A distinctive green mark in an inverted "V" or "U" shape is present at the tip of the inner tepals; in some specimens this marking may extend toward the base of the leaf. Flowering occurs between January and March, depending on local climatic conditions.

Galanthus trojanus is found only in northwestern Türkiye, specifically within the boundaries of Çanakkale Province on the Biga Peninsula. The plant inhabits areas at elevations of approximately 350 to 600 meters above sea level.

The ecosystems preferred by this species are typically open areas dominated by oak (Quercus), Turkish pine (Pinus brutia), and prickly juniper (Juniperus oxycedrus), as well as stream banks. Partially shaded areas with moist, humus-rich soil provide the optimal environment for its growth.

Due to its extremely restricted distribution, the Troyan snowdrop is classified as a species under very high threat. According to the criteria of the International Union for Conservation of Nature (IUCN), it holds the status of "Critically Endangered" (CR).

The main threats to the species' survival include habitat loss, overgrazing, land clearing for agriculture, and illegal collection. Additionally, the population’s confinement to a limited area renders the species particularly vulnerable to environmental factors such as fire and climate change. In response, the General Directorate of Nature Conservation and National Parks has developed species-specific conservation action plans and initiated efforts to protect the plant in its natural habitat (in-situ conservation).
