The rock florets ( Draba ), few are called hunger flowers, form a genus of plants in the cruciferous family (Brassicaceae). The 350 to 402 species are widespread in Eurasia , northwestern Africa, from North America to Mexico and across the Andes to Patagonia ; most species occur in the northern hemisphere. Most species thrive in the subarctic to arctic and / or subalpine to alpine flora .

Appearance, indument and foliage leaves

Draba species grow as rarely annual, biennial or perennial or usually perennial herbaceous plants , sometimes the stems lignify at their base and rarely are subshrubs . The mostly upright to ascending, rarely lying to prostrate stem axes are unbranched or, mostly in the upper area, branched.

The plant parts are hairless to very different: the trichomes can be stalked, they are simple or, for example, forked, cross-shaped, star-shaped and often several of these trichome forms are present in one species.

The leaves are mostly in basal rosettes and arranged alternately on the stem, sometimes the stem is leafless. The basal leaves are usually stalked, rarely sessile and their simple leaf blades have a smooth or serrated, rarely lobed leaf margin. If stem leaves are present, then they are stalked or sessile and their simple leaf blades with a mostly wedge-shaped or rarely hollowed blade base have a smooth or toothed leaf margin.

Inflorescences and flowers

Draba species usually have umbrella-like inflorescences , the inflorescence axes of which can lengthen until the fruit is ripe and thus develop into racemose inflorescences. Sometimes bracts present. In the inflorescences there are a few to many flowers.

The hermaphrodite flowers are fourfold. The four rarely durable, upright to ascending or rarely spreading sepals are ovate or oblong, rarely elliptical. The edges of the sepals are mostly membranous. The four mostly yellow, white, seldom pink to purple or orange, seldom red petals are obovate, spatulate, lanceolate or linear, seldom circular or oblong, they are indistinctly to clearly nailed and the upper end is blunt, rounded , notched or rarely deeply divided into two parts. The petals are usually longer, rarely shorter than the sepals. Of the six stamens , four are longer and two are shorter. The stamens can be widened at their base. The anthers are ovate or oblong with a blunt upper end. The one, two or four (as the middle ones may be missing) nectar glands stand alone or are confluent. The split by a complete, wrong septum ovary contains 4 to 70 (often up to 88) ovules . The durable, cylindrical and with a length of 0.5 to 17 millimeters barely to clearly recognizable stylus ends in a cephalic scar that is simple or somewhat bilobed.

Fruits and seeds

The thin fruit stalks are upright to ascending or spreading. The bare pods or mostly silicles are ovate, lanceolate, elliptical, oblong, linear, lanceolate or nearly circular, flat or sometimes spirally rotated. The bald or fluffy hairy, paper-like fruit flaps have distinct or inconspicuous central and lateral nerves. The placental frame (replum) is rounded. The fully formed septum is membranous and translucent. In the fruit, the seeds are arranged in two rows. When ripe, the fruits open and release the seeds.

The elongated, egg or circular seeds are mostly flattened, in Draba aleutica and Draba verna only slightly flattened, and mostly wingless, but winged in Draba asterophora , Draba brachycarpa , Draba carnosula , Draba pterosperma . The tiny net-like seed coat (testa) is not slimy when wet. The cotyledons ( cotyledons ) are bent back.

Sets of chromosomes

The basic chromosome numbers are x = 6 to 12, most often 8. The degree of ploidy within the genus is very different from diploid to octadecaploid. The species examined are most common with 23% aneuploid and the second most common with a good 20% tetraploid.

Locations and exposure

Draba species thrive predominantly in alpine or boreal areas, they rarely grow in temperate and low-lying areas of the northern hemisphere. Many species of rock florets inhabit open, stony soils : rocks, crevices, rock debris or gaps in dry grass .

About 14 Draba species are listed on the IUCN's Red List of Endangered Species . Not all states register their species on the IUCN list and there are many more Draba species in the red lists of their home states. For example, nine other species are endangered in Japan.

Systematics and distribution

Taxonomy

The genus Draba was set up in 1753 by Carl von Linné in Species Plantarum , Volume 2, pp. 642-643. The generic name Draba is derived from the Greek word drabe and means "hot", "bitter" or "burning". As Lektotypusart was Draba incana L. by Mary Letitia Green in the Bulletin of Miscellaneous Information , established in 1925, p. 51 Otto Eugen Schulz published a monograph on the Draba genus in 1927 : Cruciferae-Draba et Erophila. In: Heinrich Gustav Adolf Engler : The Plant Kingdom: ... , Booklet 89, IV, p. 105.

Synonyms for Draba L. are: Aizodraba Fourr. , Coelonema Maxim. , Dolichostylis Turcz. non Cassini , Drabella Nábelek non (DC.) Fourr. , Drabopsis C. Koch , Erophila DC. , Holargidium Turczaninow ex Ledebour , Leptonema Hook. non A.Juss. nec Rabenh. nec J.Sm. , Nesodraba Greene , Odontocyclus Turcz. , Pseudobraya Korsh. , Schivereckia Andrz. ex DC. , Stenonema Hook. , Thylacodraba (Nábelek) OESchulz .

Species and their distribution

Draba is the most species-rich and taxonomically most difficult genus of the Brassicaceae family. Over 950 taxa , almost a quarter of them as infraspecific taxa, have been published. Some authors used to associate some species with the hunger flowers ( Erophila ). But the spring hunger flower ( Draba verna L. ), for example , is considered accepted in the Flora of North America 2010 and in Ingrid Jordon-Thaden 2010, since most authors, such as Al-Shehbaz, have all Erophila species in the genus Draba can be placed.

The 350 to 402 Draba species are mainly found in the northern hemisphere in Eurasia and North America as well as in North Africa. They especially thrive in arctic, subarctic , alpine and subalpine regions. Only a few species thrive in the lower altitudes of the temperate areas of the northern hemisphere. About 70 species occur in South America in the Andes from Colombia to Patagonia . There are about 121 species in North America. There are about 48 species in China , 16 of them only there.

External system

The genus Draba belongs to the tribe Arabideae within the family Brassicaceae .

In the 21st century, due to molecular genetic data, some changes were necessary in the tribe Arabideae, this also affects species that were classified in the genus Draba and some genera poor in species were reactivated or newly established:

No longer belonging to the genus Draba :

The monotypic genus Drabella Nábelek was reactivated for one species :

The monotypic genus Pseudodraba Al-Shehbaz, DAGerman & M.Koch was established for one species in 2011 :

  • Draba hystrix hook. f. & Thomson → Pseudodraba hystrix (Hook. F. & Thomson) Al-Shehbaz, DAGerman & M.Koch

Another monotypical genus is Pachyneurum Bunge:

Since Al-Shehbaz 2012, some species previously classified by Draba have belonged to the genus Tomostima Raf. (it contains about six types):

  • Draba araboides Wedd. (Syn .: Draba arabisans var. Superiorensis Butters & Abbe , Draba incana var. Arabisans (Michaux) S.Watson , Draba incana var. Glabriuscula A.Gray ) → Tomostima araboides (Wedd.) Al-Shehbaz, M.Koch & Jordon -Thaden : It occurs in northern central to eastern North America.
  • Draba australis Hook. f. → Tomostima australis (Hook. F.) Al-Shehbaz, M.Koch & Jordon-Thaden
  • Draba cuneifolia Nutt. ex Torr. & A.Gray → Tomostima cuneifolia (Nutt. Ex Torr. & A.Gray) Al-Shehbaz, M.Koch & Jordon-Thaden : It is widespread from the USA to northern Mexico.
  • Draba platycarpa Torr. & A.Gray → Tomostima platycarpa (Torr. & A.Gray) Al-Shehbaz, M.Koch & Jordon-Thaden
  • Draba reptans (Lam.) Fernald → Tomostima reptans (Lam.) Al-Shehbaz, M.Koch & Jordon-Thaden (Syn .: Tomostima caroliniana (Walter) Raf. , Tomostima hispidula (Michaux) Raf. , Tomostima micrantha (Nuttall) Lunell ): It is widespread in North America.
  • Draba sonorae Greene → Tomostima sonorae (Greene) Al-Shehbaz, M.Koch & Jordon-Thaden

Two species previously classified by Draba have belonged to the genus Abdra Green since Al-Shehbaz 2012 :

  • Draba aprica Beadle → Abdra aprica (Beadle) Al-Shehbaz, M.Koch & Jordon-Thaden : It occurs in the US states of Arkansas, Georgia, Missouri, Oklahoma and South Carolina.
  • Draba brachycarpa Nutt. ex Torr. & A.Gray → Abdra brachycarpa Greene : It is widespread in the USA.
