The upwardly curved cabbage (Brassica repanda) , also known as mountain cabbage , is a species of the cruciferous family . He is endemic to the Southwest Alps .

description

The upward-curved cabbage is a very variable species in terms of characteristics, for which several subspecies are described. The upwardly curved cabbage grows as a perennial , cushion-forming herbaceous plant . Depending on the subspecies, it reaches a height of about 5 to 15 centimeters, but also 30 to 50 centimeters. The leafless, bare stem is unbranched. He has an ascending to upright growth. The stalked basal leaves develop a length of about four centimeters to 15 centimeters, depending on the subspecies. The glossy leaf blade varies in shape from spatulate to lanceolate. It has a meaty consistency. The leaf margin usually has a perforation. Some subspecies form leaf lobes. The stalked yellow flowers are grouped in a single cluster of two to ten, or thirty or more flowers, depending on the subspecies. The hermaphrodite single flower has a double perianth . The four green to yellowish-green sepals are upright and about 5 to 6 millimeters long. The clearly nailed four yellow petals develop a length between 10 and 15 millimeters. The ovary is on top. The fruit is a 20 to 50 millimeter long and 3 to 4 millimeter thick pod that protrudes upright from a 4 to 12 millimeter long stem. It is hairless and equipped with a 2 to 3 millimeter long beak. The fruit valves have a well-developed middle nerve, the side nerves are less well developed. The flowering period extends from June to August.

ecology

The upwardly curved cabbage is counted among the hemicryptophytes in terms of its life form . Pollination takes place via insects . The spread of the seeds is ensured by barochory .

Occurrence

The crooked cabbage is an endemic species of the southwestern Alps. The distribution area extends from the Maritime Alps to the Savoy Alps . Its area is characterized by gaps in distribution, so it is disjoint . It usually inhabits the subalpine and alpine altitude levels and rises to about 2600 meters. Lime and gravel rubble and stony lawns are preferred as locations.

Systematics

Brassica repanda subsp. blancoana

The upwardly curved cabbage belongs to the genus Cabbage (Brassica) within the family of the cruciferous plants (Brassicaceae) . The first description by the French botanist Augustin Pyrame de Candolle , which is valid today , was published in 1821 in his Regni Vegetabilis Systema Naturale , Paris. Before that, Willdenow had placed the species under the name Sisymbrium repandum in the genus of the rocket in 1800 . Synonyms are Diplotaxis humilis ssp. repanda (Willd.) P. Fourn., Diplotaxis saxatilis DC. Sensu lato, Sisymbrium repandum Willd. Several subspecies of Brassica repanda have been described:

The subspecies Brassica repanda ssp. glabrescens (Poldini) Gómez Campo was granted species status as Brassica glabrescens Poldini by some taxonomic authors as of 2011 . Brassica glabrescens has been recognized as a separate species since 2012 .
