description

Egyptian ox tongue, flowering and fruiting

Flower with the appendages in the center

The Egyptian ox tongue is an annual plant that can reach heights of 5 to over 40 centimeters. The growth is prostrate to ascending, it is branched from the base and the side branches are also ascending. The stems are bristly. The leaves are lanceolate to obovate; the lower ones are stalked, the upper ones seated. They are 2–12 centimeters long and 1–5 centimeters wide, bristly, prickly serrated and on the blade with large white bumps. The small flowers are in loose and few-flowered inflorescences. The short and bristly flower stalks are slightly shorter than the calyx; they lengthen and curve at the fruit time. The salver-plate-shaped corolla, with slightly hairy and outwardly curved scales, appendages to the throat, is pale yellow and slightly unevenly five-lobed. The edge is about 5–6 millimeters wide, the short flower tube is almost straight and somewhat the same length as the bristly calyx with narrow tips, which is divided almost to the base. The stamens are very short and at the bottom of the corolla tube.

The flowering period is February to May. There are Klaus fruits formed in stable chalice.

The number of chromosomes is 2n = 16.

distribution

The Egyptian ox tongue occurs in the eastern Mediterranean region, in the Middle East and on the Arabian Peninsula. So far the westernmost outpost was in Tunisia , but the species was newly discovered in Spain. It also occurs in Turkey. The species grows on sandy beaches, in the garigue and on ruderal areas .

Taxonomy

The Egyptian ox tongue was first described by Carl von Linné as Lycopsis aegyptiaca in Sp. Pl .: 138, 1753. It was written by Alphonse Louis Pierre Pyrame de Candolle in Prodr. 10:48, 1846 as Anchusa aegyptiaca (L.) A.DC. placed in the genus Anchusa .
