Hypohydrophilyis a true hydrophily that occurs beneath the surface of water. Is Lotus Water pollinated flower? Answer. All Characteristics, some of the leaves are floating at the surface of the water, the leaf blade is obovate (egg-shaped, but with the widest point above the middle of the leaf blade), the leaf blade is triangular, with the stalk or attachment point on one of the sides, the flowers grow out of the axil (point where a branch or leaf is attached to the main stem), the inflorescence has only one flower on it, the stamens are not fused to the petals or tepals, the plant lives only a single year or less, the tip of the floating leaf blade is obtuse (bluntly pointed), the tip of the floating leaf blade is truncate (ends abruptly in a more or less straight line as though cut off), the underwater leaf blade is linear (very narrow with more or less parallel sides), the underwater leaf blade is spatulate (spoon-shaped; narrow near the base, then suddenly widening to a rounded tip).

At maturity, male flowers are detached from male inflorescence and begin to float on the water surface. Monoecious plants exhibited a positive association with lakes surrounded by urbanized or forest land, and perennial species tended to occur more frequently in dam reservoirs than in other lake types. heterophylla Most insect pollinated flowers have a landing platform. Can you please help us? • Anemophily is reported for amphibious and terrestrial species.
