Cymules solitary, 2-flowered; peduncle 0.5-8 cm. Pedicel 0.5-1.5 cm, with 1-1.8 mm patent nonglandular trichomes and 0.2-0.5 mm patent glandular and nonglandular trichomes; bracteoles lanceolate. Sepals (1-)2.5-5.5(-6) mm, mucro 0.1-0.2 mm, ratio of mucro/sepal length = 0.03-0.1, outside with 1-1.5 mm patent nonglandular trichomes and 0.2-0.5 mm ± patent nonglandular and glandular trichomes, outside glabrous. Petals bright purple, 3-8.5(-10.5) mm, erect to patent, both surfaces glabrous, margin basally ciliate, apex emarginate with a 1-2.5 mm notch. Staminal filaments whitish, lanceolate, glabrous except proximal half with some 0.1-0.2 mm cilia; anthers purplish, 0.7-1.5 mm. Nectaries 5, hemispheric, glabrous. Stigma purplish. Fruit 0.8-1.4 cm, erect when immature; mericarps transversely wrinkled, without a basal callus, glabrous but with a few cilia at base; rostrum 6-11 mm, with a 1-3 mm narrowed apex; stigmatic remains 1-2 mm.

Annual herb, stems up to ±45cm long, decumbent or ascending, pilose with glandular and eglandular hairs. Stipules ovate, acute. Radical leaves tufted, petioles up to 250 mm long, pilose as the stem; blade up to 60 mm in diam., divided halfway or more to the centre into 5-9 lobes, lobes oblong-obovate, deeply 3-fid, both surfaces thinly pilose; cauline leaves similar but petioles progressively shorter and blade reduced. Peduncles opposite the upper reduced leaves eventually forming large compound cymes, usually 2-flowered, pilose with spreading hairs often gland-tipped. Pedicels similar to peduncles. Sepals ±2.5-4 x 1.5-2.5 mm, pilose. Petals ±3-7 x 2-3 mm, deeply notched, purplish-pink. Rostrum glandular-pubescent. Carpels transversely ridged, glabrous.
Ähnlich wie G. pusillum, aber Stängel und Blütenstiele nebst kurzen Haaren mit 1–2 mm langen, abstehenden Haaren. Obere Blätter meist wechselständig, nur bis etwa zur Mitte 5–9teilig. Kronblätter 4–7 mm lang, rosa, vorn tief und spitz aus
