Trifolium fragiferum
Strawberry Clover (Trifolium fragiferum )
The Strawberry Clover (Trifolium fragiferum ), also raspberry Klee, a species of the subfamily Fabaceae ( Faboideae ) is belongs to the legume family ( Fabaceae or Leguminosae).
Features
The strawberry clover is a perennial herbaceous plant; it grows prostrate / creeping, branched, and is 20 to 30 inches long. The alternate and spirally arranged, petiolate leaves are clover typical three parts. The leaf blades of the leaflets, 5-30 mm long, 4,5 up to 18 mm wide, are ovoid, have a finely serrated edge and bluish - green. The petiole is 1.7 to 16.3 cm long. The stipules are fused to the petiole.
The little head shaped buds contain 10 to 30 flowers in flowering state, and have a diameter of about 10 millimeters, crop time to 20 ( 25 ) mm. The flower stalk is 0-1 mm long. The hermaphrodite flowers are zygomorphic and fünfzählig. The pink flowers are - in contrast to the Persian clover ( Trifolium resupinatum ) - not rotated (the " flag " that is facing upward, the keel down). The calyx is indistinct 20 - annoying, double lip and 3.5 to 4 mm long. The crown is 4.5 to 8 mm long. The flowering period extends from June to September. There is insect pollination.
The pulse is 1.5 to 2 mm long and 0.8 to 1 mm wide. At the time the fruit calyx hairy upper lip is distended vesicular, whereby the seed heads get a very striking appearance, in the form of a berry fruit reminds ( hence the name ).
Habitat requirements
The Strawberry Clover is a characteristic type of coastal salt marshes, for example, on the North Sea - where it occurs in beach thrift companies. Also on the Baltic coast, there are regular occurrences. Inland salt particular points ( saline groundwater outlets places in the environment of potash and the like) are populated, which are also sound - bödig and often calcareous. May also be mentioned comb grass companies, impact and flood lawn and digging and roadsides with corresponding site conditions.
Dissemination
Trifolium fragiferum is described as Mediterranean and sub-Mediterranean, so rather Flore southern European element in the temperate - continental region of Europe has its center of gravity, but was deported including through grassland management in other regions. While in southern Europe and northwest Africa the subspecies subsp. bonannii is represented ( in Germany only ), and on the coasts of southern Scandinavia, the nominate subspecies grows in northern central Europe subsp. fragiferum. The species occurs mainly at lower altitudes; in the central mountain range only within Keuper areas ( on the Swabian Alb probably down to 880 m above sea level ). While the spread on the coasts of Central Europe is very steady, the finds are scattered in the interior as a function of the salt- tolerant and other ecological behavior of plant and irregular. A certain accumulation of evidence can be observed within Germany in the northeast German lowlands ( including, inter alia, in Lower Saxony Wendland, from where the photos were taken ). As Stromtalpflanze there are also areas along the Elbe, Rhine and other large rivers.
Outside Europe, this species was introduced to different regions of the world, as in the U.S. (especially in the western states ), to New Zealand and South Australia.
Strawberry Clover nationwide will not result in the red list of endangered species, but in different German states.
