Winter Cress, Barbarea



The Fairlawne field just before the Cricket Bat Willow plantation has thousands of a Barbarea plant on it, about 25 - 30 cm high.

The fruit \are curved initially but appear to straighten up and also become more appressed when mature.

The styles may lengthen slightly as the fruit mature, but the longest one I measured was still no more than 2 mm long. Equally the longest fruit I have measured so far was no more than 40 mm, (4 cm).The pedicel was stou, definitely not more slender than the fruits themselves.

The flowers were about 5 mm when measured across, with the petals about twice the length of the sepals,

The uppermost leaves were quite lobed at the base, so it is unlikely to be B. vulgaris or B. stricta.



The leaves tasted quite sour, so it is unlikely to be B. verna.
