Cistaceae

Sage- Rockrose (Cistus salviifolius )

The plant family of rockrose ( Cistaceae ) belongs to the order Malvenartigen ( Malvales ).

Description

These are mostly small shrubs or herbaceous plants, often they have an aromatic odor, some species are xerophytes. The change-constant leaves are simple, they can be herbaceous or coriaceous. There are species in which the leaves are partially or completely reduced. As a protection against drying many kinds are hairy, with very different forms of hairs occur, but most often they are star-shaped. Other protective mechanisms are curling or leaf shedding, or the formation of water-storing rhizomes.

The flowers appear singly or in zymösen inflorescences.

The hermaphrodite, radial symmetry, usually five petals are always colored quite striking and have a double perianth. The short-lived, free petals can be very large and often look wrinkled from. Sepals, there are five or three; if five sepals are present, then the outer two are much smaller.

Among the most numerous ( rarely three, often up to 100) stamens mature at the Zistrosengewächsen first the inner ( centrifugal), which is relatively unusual. In many species the anthers hide the scar, and writhe upon contact to the outside ( sensitive stamens ), so that the scar is released. Carpels per flower are three or five to ten exist, they have grown to a superior ovaries. It is a pen and a scar present.

There are made with proteinaceous seed capsule fruits.

Dissemination

The areas of most taxa are in the moderate latitudes of the northern hemisphere. Most species of the family are found in the Mediterranean region (Southern Europe, Asia Minor, North Africa). Only a few species are also found in eastern North America or in small isolated areas of South America ( Crocanthemum, Hudsonia ).

The species usually prefer dry, sunny locations. The family is an important part of scrubland vegetation of the Mediterranean area.

Genera

There are eight to ten genera with 175-200 species:

  • Rockrose (Cistus L.): With about 18 species in the moderate latitudes of the northern hemisphere.
  • Crocanthemum Spach: With about 24 species; they occur in America.
  • Needle florets ( Fumana ( Dunal ) Spach ): With about nine species in Europe and North Africa, including: Ordinary needle florets ( Fumana procumbens ( Dun. ) Gren. % Godr. )
  • Upright needle florets ( Fumana ericoides ( Cav. ) Gandoger )
  • Needle lemon thyme herb ( Fumana thymifolia (L.) Spach )
  • Hudsonia ericoides L.; the species occurs in North America
