ⓘ Boechera

Boechera is a genus of the family Brassicaceae. It was named after the Danish botanist Tyge W. Bocher, who was known for his research in alpine plants, including the mustards Draba and Boechera holboellii. According to recent molecular based studies Boechera is closely related to the genus Arabidopsis which also includes the widely known model plant Arabidopsis thaliana.

Until recently, members of this genus were included in the genus arabis, but have been separated from that genus based on recent genetic and cytological data. Unlike the genus arabis x=8 Boechera has a base chromosome number X=7. Many taxa are triploid. Boechera is a primarily North American genus, most diverse in the Western United States, but its range also includes Greenland and the far East. The genus is poorly known, and species are difficult to separate morphologically though some clearly distinct from each other types are known.

Most members of the genus-perennials with hairy leaves with stellate hairs, narrow curved fruit, and small white to purple flowers in elongated racemes. Relationships within the genus are unclear, and some Eastern North American species, including Boechera laevigata can be a treasure different from the other members of the genus.

A very interesting feature of many species of the genus asexual reproduction, a process known as apomixis. Microsatellite data showed that some of apomictic lines of hybrids between two or more sexual parents.
