Flowering of Lemna L. species in Lithuania. – Botanica Lithuanica, 2(2): 193–197

Data on the flowering of Lemna gibba and L. minor in Lithuania are presented. Flowering L. gibba was collected in 1936 and 1936, L. minor – in 1971, 1973 and 1995. The air temperature of those years was analysed, however, no clear relations between the flowering and air temperature were revealed. The flowering probably depends on microclimatic and ecological conditions of a habitat. The map of known localities where Lemna species flowered is presented.
