frogbit การใช้

The name " American frogbit " refers to another aquatic plant, " Limnobium spongia ".
West Moor lies south of Curry Rivel, Langport, and Frogbit ( " Hydrocharis morsus-ranae " ).
The Exminster Marshes, a series of fields drained by dykes and ditches, carry several plants rare in Devon including parsley, water dropwort ( " Oenanthe lachenalii " ), flowering rush " Butomus umbellatus " and frogbit " Hydrocharis morsus-ranae ".
Amazon Frogbit in captivity has two hazards to its health which aquarium owners can avoid : ( 1 ) water droplets on the tops of the leaves can rot the plant ( they must be kept dry ), and ( 2 ) some species of aquatic snail appear to like to eat the spongy material on the bottoms of the plant leaves ( keep them near the center of the tank, not against the glass on the edges .)
Other plant species which are otherwise scarce or absent in the Bristol region but found in high concentrations on the North Somerset Levels are : Flowering-rush ( Myles, p . 210 ), Lesser Water-plantain ( Myles, p . 210-1 ), Frogbit ( Myles, p . 210-1 ), Lesser Pondweed ( Myles, p . 212-3 ), Small Pondweed ( Myles, p . 212-3 ), Hairlike Pondweed ( Myles, p213 ), Opposite-leaved Pondweed ( Myles, p . 213 ) and Horned Pondweed ( Myles, p . 213 ).
