Context paragraphs:
Barbarea: Barbarea (winter cress or yellow rocket) is a genus of about 22 species of flowering plants in the family Brassicaceae, native to temperate regions of the Northern Hemisphere, with the highest species diversity in southern Europe and southwest Asia.  They are small herbaceous biennial or perennial plants with dark green, deeply lobed leaves and yellow flowers with four petals.

Cryptotaenia elegans: Cryptotaenia elegans, Spanish: perejil de Monteverde ("Parsley of Monteverde"), is a plant species in the genus "Cryptotaenia" endemic of the Canary Islands, Spain.

Barbarea australis: Barbarea australis is a morphologically and ecologically typical "Barbarea" species with an unusual distribution: it is an endemic and threatened species from Tasmania.  The leaves have a large end-lobe and only few side lobes, much like the leaf-shape of "Barbarea stricta" and "Barbarea orthoceras".  With regard to defence chemicals (glucosinolates), it is similar to other members of the genus.

Cryptotaenia: Cryptotaenia, also honewort, is a genus of two species of herbaceous perennial plants, native to North America, Africa, and eastern Asia, growing wild in moist, shady places.
