Brassicaceae tribe Camelineae

Annuals, biennials, or perennials; eglandular. Trichomes stalked or sessile, stellate, dendritic, or forked, sometimes mixed with simple ones. Cauline leaves usually sessile, rarely petiolate or subsessile; blade base auriculate or not, margins usually entire, sometimes dentate or, rarely, lyrate. Racemes ebracteate [bracteate], often elongated in fruit. Flowers actinomorphic; sepals erect, spreading, or ascending, lateral pair usually not saccate basally; petals [absent] white, yellow, pink, lavender, or purple [orange], claw present, often distinct; filaments unappendaged, not winged; pollen 3-colpate. Fruits silicles or siliques, dehiscent or indehiscent, unsegmented, terete, latiseptate, or angustiseptate; ovules 2–200[–numerous] per ovary; style often distinct; stigma usually entire [2-lobed (subentire in Turritis)]. Seeds biseriate or uniseriate [aseriate]; cotyledons accumbent or incumbent.

Distribution

North America, Europe, Asia, Australia.

Discussion

Genera 7, species 37 (6 genera, 12 species in the flora).

Camelineae appeared as a monophyletic lineage in M. A. Beilstein et al. (2006); the sampling included seven genera and, with study of further genera, the boundaries of tribe may well need to be redefined.
