Phenology, seed morphology, seed viability and germination behabiour of some wetland plants in control at moist filter paper in petridishes was carried out in wetland plants-Aeschynemone asper L. (Fabaceae); Eragrostis unioloides (Retz.) Nees exsteudel (Poaceae); Hygrophila auriculata (K. Schum) Heine (Acanthaceae); Pesicaria barbatum (L.) Hara (Polygonaceae); and Rumex dentatus L. (Polygonaceae) were studied at Biratnagar. Number of seeds per gram ranged between161-12722. Viable seeds of A. asper (98%) and P. barbatum (55%) had no germination but E. unioloides had cent percent germination; H. auriculata, and Rumex dentatus showed 96% germination. A.asper and E. unioloides germinated in early rainy; spent vegetative phase up to August- September; and completed flowering, fruiting and seed maturation before winter.
