The above first records from Myanmar and Thailand are based on Keenan et al. 3918 (E) and Maxwell 90-149 (MO), respectively.
Cardamine flexuosa is one of the most variable species of Brassicaceae, especially in stem direction, plant height, density of indumentum, flower size, degree of zigzagging of the raceme rachis, orientation of fruiting pedicels and, most dramatically, number, shape, size, base (sessile vs. petiolulate), and margin of lateral leaf lobes. Although Schulz (Bot. Jahrb. Syst. 32: 464-473. 1903) recognized 20 infraspecific taxa in C. flexuosa, an examination of the types of most of these reveals that he confused the limits of least four different species, including C. parviflora, C. scutata, and the North American C. pensylvanica Muhlenberg ex Willdenow. Only a small fraction of the vast number of variants of C. flexuosa have been accorded infraspecific ranks, but all of those occur sporadically throughout the range of the species, and the present authors prefer to avoid the recognition of infraspecific taxa that are based on unreliable characters, especially the morphology of lateral leaf lobes.
Although Cardamine occulata was based on Chinese material, it was not mentioned in FRPS, and it represents only a minor variant of C. flexuosa.
Cardamine flexuosa is used medicinally.

Cardamine flexuosa
provided by wikipedia EN
Cardamine flexuosa, commonly known as wavy bittercress or wood bitter-cress, is an herbaceous annual, biennial, or short-lived perennial plant in the cabbage family (Brassicaceae).[1]
Description
This is a small flowering plant growing to a height of no more than 30 cm, usually perennial, with few short, erect stems. The leaves pinnate, mostly at the base, each with about 5 pairs of rounded leaflets. Flowers very small, white, 3 – 4 mm across with 6 stamens. Fruits of C. flexuosa generally do not overtop the flowers, a feature distinguishing it from Cardamine hirsuta.[2]
Distribution
Common throughout the British Isles[3]: 401 and Europe.[4]
Habitat
In Ireland common in woods shady and damp places.[5][2]
Uses
In Northeast Indian State, Manipur, it is eaten and often used as garnishing Eromba and known as Chaantruk.
