Comments: | Similar to Annual Celery (Apium annuum) which is generally a smaller erect plant with branches to 20 cm long only, pinnate leaves to 5 cm long only and fruit with noticeable furrows between the ribs. Two varieties of Apium prostratum are recognised. Variety prostratum has long linear to lanceolate leaves or leaf segments, 6-15 times longer than wide. Variety filiforme has divided leaflets with elliptic, ovate or obovate segments, 2-3 times longer than wide. |
