syn: Galium ibicinum Boiss. & Hausskn.
Dichotomously branched small annual herb with 4-angled stems with retrorsely scabrid angles; leaves in whorls of 4-6, 10-15 mm long, 2-4 mm broad, oblanceolate, retrorsely scabrid along margin, apex mucronate-cuspidate; cyme 1-flowered on 15-25 mm long peduncle; flowers white, 1.5 mm across; fruit didymous, 2-3 mm across, covered with long slightly hooked hairs without broad base.
The plant is closer to G. aparine but clearly differs in less than 6 leaves at each whorl (6-8 in G. aparine) and single flowered cymes.
