Nymphoides peltata is a typical representative of higher aquatic plants. Despite its wide geographical distribution, N. peltata is a rather rare species. The development of effective measures to protect a species in any territory is possible only if there is complete information on the status of its populations. Study of the size and morphological structure of plants plays an important role in the system of population studies. The purpose of this publication is to characterise the dimensional values of N. peltata plants growing in the waters of the Desna River basin and to assess the impact of the leading ecological and coenotic factors on them. Five N. peltata cenopopulations were studied. Morphometric analysis was used, which was accompanied by the recording of 12 static metric morphoparameters. The results of the study showed that N. peltata plants respond to changes in ecological and cenotic conditions with a statistically significant change in the values of the leading morphological parameters and total size. As a result, plants of a characteristic habit and morphostructure are formed in each habitat. Based on the results of the study of plant size and the assessment of the influence of the leading ecological and coenotic factors, it was found that the most favourable for the formation, growth and development of N. peltata coenopopulations are large floodplain lakes, which are characterised by the following set of indicators: no current, water depth of 30–80 cm, transparency of at least 75–80% of the maximum depth, muddy bottom sediments, and projective coverage of the species of 70–95%. The habitats of the Nymphoides peltata subpurum (floodplain lake) and Nymphoides peltata–Ceratophyllum demersum (floodplain lake) communities most closely correspond to the parameters of the ecological and cenotic optimum.
