Description
editThe distribution of Cardamine barbaraeoides is restricted to the northern part of the Southern Pindos mountains and the southern part of the Northern Pindos mountains.[1] C. barbaraeoidies grows in wetter soil, commonly growing along small streams, stream banks, wet rock faces, and in springs on wet meadows or pastures.[2] At elevations between 1,000 and 1,800 meters above sea level.[1][2] It is a perennial and grows primarily in the temperate biome. C. barbaraeoides has a petal color that is white with violet anthers; the overall inflorescence is racemose.[1][2] The stigma is inconspicuous absent basal leaves and is as wide as the style.[1][2] The basal leaf rosette is glabrous, pinnate, with 1–2 leaflets, and is loosely congested near the glabrous stem base.[1] 9–21 Stem leaves are equally distributed on the stem, are pinnate, and are similar to basal leaves[1]
Cardamine barbaraeoides is a tetraploid with 32 chromosomes.[3] Analysis of sequencing suggests and allopolyploid origin with its progenitors being derived from two major clades of diploids C. amara and C. acris.[3] A second possible scenario is that wide-ranging genomic changes in the polypoid in response to a “genomic shock”, including nonhomologous recombination, significantly transformed and differentiated the polypoid genome from its diploid progenitors.[2]
