Vegetative characteristics

Lomatogonium species grow as annual or perennial herbaceous plants . Some species form rhizomes as persistent organs. A few side roots either start from a main root or they are fleshy and are formed on the rhizomes. The prostrate, ascending to upright stems are branched to unbranched and have stripes or edges. The cross-opposite leaves are simple.

Generative characteristics

The flowers are terminally single or usually in terminal or lateral zymous inflorescences . The flower stalk is usually longer than the flower. The hermaphroditic flowers are radial symmetry and usually five, rarely four or ten. The usually five sepals are fused at least at their base. The usually five white, pale blue to blue, clearly two-colored petals are fused at least at their base. Each petal has two ciliate nectaries at its base. There is only one circle with mostly five (rarely four or ten) stamens . The somewhat flattened stamens start at the base of the corolla tube and do not twist in a spiral. The mostly blue, rarely yellow anthers are at most as long as the stamens. The ovaries are sword-shaped, cylindrical or ovate-ellipsoid. There is no stylus. In the seated scars , the scar flaps run down the ovary sutures.

The bilobed capsule fruits contain many seeds . The seed coat is almost smooth.

Systematics and distribution

The genus Lomatogonium was established in 1830 by Addison Brown in Flora , 13, p. 221. Synonyms for Lomatogonium A.Br. are: Pleurogyne Eschscholtz ex Chamisso & Schlechtendal , Swertia subgen. Lomatogonium (A.Braun) Satake , Pleurogynella Ikonnikov . The genus Lomatogonium belongs to the subtribe Swertiinae from the tribe Gentianeae within the family Gentianaceae .

The generic name Lomatogonium is derived from the Greek words loma, lomatos for hem and gonia for corner, and refers to the scars running down the ovary. The common German name Saumnarbe also refers to this feature.

The Holarctic distribution area includes North America and temperate Eurasia . The center of biodiversity is China with 16 species. Only two species occur in Europe. The only Central European representative is the Carinthian Tauernflower ( Lomatogonium carinthiacum ).

The genus Lomatogonium includes 18 to 21 species (here with their distribution):
