The bare, bluish-green frosted, somewhat fleshy leaves are 1.5 to 4 centimeters long, narrowly lanceolate to linear and three-veined.
Inflorescence and flower
Bald, racemose inflorescences are formed. The flower stalk is about as long as the sepals.
The hermaphrodite flower is clearly zygomorphic , five-fold and has a double flower envelope . The 9 to 13 millimeter long corolla has two lips. The (pale) yellowish to lilac-white or pale bluish-purple and dark purple longitudinally striped petals are fused. The split upper lip is slightly bent back and veined purple. The lower lip ridges are lemon yellow or rarely white. The straight 3 to 5 millimeter long spur is trimmed.
Fruit and seeds
The 3 to 4 millimeter long capsule fruit is almost spherical. The reticulate-wrinkled seeds are ellipsoidal-triangular and without a skin border.
Chromosome number
The number of chromosomes is 2n = 12.
ecology
The flowering period extends from June to September with the peak in July and August. The striped toadflax grows as a geophyte or hemicryptophyte . The pollination is done by insects. The diaspores are spread out by the wind.
Occurrence
It is an oceanic-sub-Mediterranean floral element . The distribution area of the striped toadflax is mainly in southwest Europe , from northern Spain and northwestern Italy to western Germany and Belgium . By carryover was made to expand the area to England and Scotland , central Sweden and southern Finland , eastward to Poland and the Czech Republic .
In the Austrian federal states of Lower Austria, Upper Austria, Styria, Carinthia, Salzburg (there only in the city of Salzburg), Tyrol and Vorarlberg, it rarely occurs as an inconsistent or locally naturalized neophyte .
The striped toadflax colonizes ruderal areas, especially railway systems and dams as well as gaps in overgrown roadsides and forest clearings on lime-poor, rocky-loose, nitrogenous soils in warm summer locations of the colline to submontane altitude . The striped toadflax occurs in Central Europe in societies of the order Galiopsietalia segetum and the associations Epilobion angustifolii, Trifolion medii or Dauco-Melilotion.
