The Colorful Bellardie ( Bartsia trixago L. , syn .: Bellardia trixago (L.) All. ) Is a plant type from the family of Broomrape family (Orobanchaceae). Pliny the Elder uses the word trixago for noble germander , its etymology is unknown.

features

The Bunte Bellardie is an annual , herbaceous semi-parasite that reaches heights of 15 to 70 centimeters. It is hairy, upright and usually simple, but sometimes more branched in the upper area. The rhizome is short and clearly thickened. The leaves are linear to linear-lanceolate, 15 to 90 × 1 to 15 millimeters in size, sitting, opposite and blunt to elliptical. The leaf margin is roughly and bluntly serrated.

The inflorescence is a dense, terminal spike . Its bracts resemble the foliage leaves in the lower area, becoming smaller towards the top, ovoid to heart-shaped and with entire margins. The flower color varies greatly even within a population. The flowers can be pure yellow or white with purple-pink, plants with pure white flowers are also rare. The chalice is bulbous to bell-shaped, 8 to 10 millimeters long and deeply divided into 2 short-toothed sections both above and below. The calyx lobes are shorter than a quarter of the length of the tube. The corolla is 2 to 2.5 inches long and fused. The end of the tube is a helmet-shaped upper lip and a blunt three-lobed, flat lower lip. There are 4 stamens that have grown in the corolla tube. The anthers have bristly hair. At the upper ovary the end of the style is thickened like a club.

The capsule fruit is a glandular hairy, spherical and as long as the calyx. The numerous small seeds are elliptical to kidney-shaped, ribbed lengthways, finely striated and up to 0.7 millimeters long.

The flowering period extends from April to July.

The number of chromosomes is 2n = 24.

Occurrence

The colorful bellardia occurs from the Mediterranean to Central Europe in the north, to the Canaries in the west and to Iran in the east. It is also native to Madeira and southern Africa. It is a neophyte in Ethiopia, Kenya, Yemen, Australia, Texas, California and South America.

Systematics

The systematic classification of the species has not been clarified beyond doubt. Some authors classify it as Bellardia trixago in a monotypic genus, but molecular biological studies have shown that the genus Bartsia is not monophyletic to the classically recognized extent . From these studies, the species Bartsia trixago is classified in a clade which, in addition to Bartsia trixago and Bartsia crenata, also contains both representatives of the genus Parentucellia :

Bartsia crenata
