Title
The name of the young may also be worn by another plant - sedum ( lat. Sédum ácre ) from the same Crasty family [4] .
Some species of this genus (as well as some species of other crass jugs) have the Russian names “Kamenny Roza” and “Rabbit Cabbage”.
Botanical description
Perennial fleshy grasses , pubescent with glandular hairs, less often almost naked, forming very thick multi-leaf rosettes of leaves 1–15 cm in diameter and numerous stolons bearing small rosettes of leaves.
Flowering stems are usually pubescent with fine glandular hairs, erect and unbranched. Monocarpics . Succulent leaves , alternate, entire, usually ovate or oblong, sharp or pointed, ciliate along the edge.
The flowers are regular, 8-20-dimensional, bisexual, with a double perianth , almost sessile, gathered in corymboid-paniculate inflorescences , separate inflorescences of which are monochasions . Sepals are fleshy, fused at base, entire, usually covered with short, simple or glandular hairs, rarely bare. The petals are lanceolate , always longer than the sepals, usually starry prostrate, on the edges and the outside are white, yellow, yellow-green, red, pink or purple. Stamens twice as large as the petals, from 16 to 40; the opposite to the petals grow at the base to them, and the next to the petals are free. Filaments usually flattened, pubescent or, less commonly, bare. Anthers oblong ovate. Nectar glands subpedic, small, plate-shaped, whole on top. Gynetsa is free from 8–20 uneven-borne, oblong-ovoid, usually glandular, sedentary carpels . Stilodii slightly shorter ovary , straight, naked. Stigmas are small, capitates.
Fruit of 8–20 oblong ovate or nearly lanceolate, pubescent with glandular hairs, multi-seeded leaflets .
Origin and distribution
The genus includes about 30-50 species . Distributed in Central , Southern , Eastern Europe , the Caucasus , in Small and Southeast Asia , mainly in mountainous areas.
In Central Russia , one species grows - the young ( Russian) ( Sempervivum ruthenicum ), in the Caucasus - the young Caucasian ( Sempervivum caucasicum ).
Very easily hybridizes both in nature and in culture . There are many varieties .
Types
Representatives of the genus Sempervivum are easy to recognize, but it is quite difficult to distinguish between its species, since even representatives of the same species may look different under different growth conditions and at different times of the year. Many species of molodilas have been described without clear distinctive features among themselves. The problem of establishing species is complicated by the high frequency of occurrence of natural interspecific hybrids .
