Lesser Burdock - Arctium minus
Medium to tall plant to 1.5 metres. Stems hairy, often reddish, with down-curved branches. Basal leaves large (to 50 cm) with hollow stalks. Flowers purple - flowerheads 15 to 18 mm (15 to 25 mm in fruit) the outside bracts green or purple tinged often cottony when young.
Greater and Wood Burdocks
A more or less racemose inflorescence (the outer flowers have short stalks or are stalkless). Hollow petiole to the basal leaves. It can have glabrous or hairy flowers.
Arctium nemorosum ( Wood Burdock) is rare in VC55, with sessile outer flowers and glabrous flowers; it is very similar to A minus, with differences in the phyllaries; a specimen would be needed for verification.
