Annual herb, stems up to ±50cm, erect or ascending, pilose with spreading glandular and eglandular hairs. Stipules ovate, acuminate. Radical leaves tufted, petioles up to ±250 mm long, pilose as the stem; blade up to ±65 mm in diam., divided less than halfway to the centre into 5.7 lobes, lobes cuneate in outline, deeply crenate, both surfaces thinly pilose; cauline leaves similar, but petioles progressively shorter and blade reduced. Peduncles opposite the upper leaves and shorter than they, eventually forming compound cymes, usually 2-flowered, pilose with spreading hairs mostly gland-tipped. Pedicels similar to peduncles. Sepals ±4.5 x 1.5 mm, pilose. Petals ±7.5 x 2.5 mm, oblong, tips rounded or slightly notched, pink. Rostrum pilose with spreading glandular and eglandular hairs. Carpels smooth, pilose.
A native of Eurasia, with more rotund lvs cleft only to about the middle, the segments shallowly lobed about the rounded or truncate summit, and with smaller fls, the sep at anthesis 4–5.5 mm, blunt or shortly subulate-tipped, the fr 15–20 mm, is rarely adventive in our range. It might sometimes key to G. molle, but has the mature carpel-bodies hirsute and not wrinkled.
