Coastal areas can be tricky to landscape. The Buttonwood is … the water line. mangrove, red mangrove (Rhizophora mangle), and white mangrove (Laguncularia. They are a much more dull green color and have a more rounded leaf-shape compared to the other two species. The most noticeable differences between the native white mangrove and Lumnitzera are that the invasive mangrove has alternate leaves while the white mangrove has opposite leaves, and Lumnitzera leaves lack a true petiole with the leaf margin tapering gradually to the stem. White mangroves can secrete salts directly through two salt glands at each leaf base which are then removed by environmental factors, such as wind or rain. White mangrove leaves are lovingly called the “frankenstein” leaves because of the two small glands or bolts on the base of each stem. Buttonwood (white mangrove family) Conocarpus erectus (Combretaceae) Origin: coastal areas of Florida and the Caribbean to South America. distinguishing characteristics are the rounded leaves that feature Reported to be astringent and tonic, white mangrove is a folk remedy for dysentery (Duke and Wain, 1981), Hager's Handbook mentions that the bark is used for aphthae, fever, and scurvy (List and Horhammer, l969–1979). The Red mangrove ( Rhizophora mangle) is the tallest of all local species.It grows to heights over 80 feet tall (25m). Flower-heads are at the end of branches or in the junction between stem and leaf. White mangroves produce greenish-white flowers in spikes, blooming from spring to early summer. Autumn colored Mangrove leaves washed up on white sandy tropical island beach. TIME OF YEAR: All three mangroves can seed all year but they favor spring. These glands are sugar glands called nectaries and they excrete a floral nectar that attracts pollinators. mangrove, red mangrove (Rhizophora mangle), and white mangrove (Laguncularia. TIME OF YEAR: All three mangroves can seed all year but they favor spring. The light yellow-green leaves are broad and flat with two glands located at the base of the leaf where the stem originates.

The term ‘mangrove’ also applies to thickets and forests of such plants. The easiest way to identify the white mangrove is by the leaves. Closest to shore, white mangroves resemble conventional trees the most and only sprout breathing tubes or tall arching roots when they need to keep above the tide. * A propagule is not a seed, but actually a tiny tree. MANGROVES: - Grey mangroves have leaves with glands that excrete salt - Some species such as the Grey Mangrove can also tolerate the storage of large amounts of salt in their leaves.

Plants that exclude salt prevent it from entering the membranes of their roots. Racemosa, Origin: Gulf mangrove species in Florida—red, white and black. Local Species Identification. Habitat range in Florida is limited by temperature; however, the decreasing frequency, intensity, and duration of winter freeze events in North Florida has likely played a role in expanding the range of both red and black mangroves along the Panhandle coastline. The Buttonwood is buttons that go from green to red. White mangrove leaves are lovingly called the “frankenstein” leaves because of the two small glands or bolts on the base of each stem. 9. The white mangrove features a pair of nodular, salt-excreting glands found near the tip of each leaf stalk and a series of blackish glands between the middle vein. The seeds or fruit of the The white mangrove’s dispersal period is the shortest at 5 days, which also includes germination. White mangrove definition is - a small shrub to moderately large tree (Laguncularia racemosa) of the family Combretaceae that grows in brackish waters along the seacoasts of western Africa and tropical America, has flowers with fine small petals and a persistent top-shaped calyx, and is locally important as a source of tannins. 7. Florida mangroves have leaves that are directly opposite one another on the stem (except buttonwood, which has alternate leaves). This small tree or shrub grows rapidly in rich soils to heights of 50 feet (15 m). Black mangroves grow slightly closer to shore than red mangroves and send up thin tubular roots to absorb oxygen and exude salt from their leaves. Laguncularia racemosa, the white mangrove, is a species of flowering plant in the leadwood tree family, Combretaceae. The white mangrove features a pair of nodular, salt-excreting glands found near the tip of each leaf stalk and a series of blackish glands between the middle vein. Fruit: The leaves have microscopic pores which excrete salt. those of the black mangrove. The white mangrove (Laguncularia racemosa) usually occupies the highest elevations farther upland than either the red or black mangroves.Unlike its red or black counterparts, the white mangrove has no visible aerial root systems. ©Mark W. Skinner. The easiest way to identify white mangroves is by the leaves. Aquarium Chemistry "The antitumor activity of the bark extract is attributed to its tannin content" (Morton, 1981). Still, other mangroves, such as the white mangrove, secrete salt directly from the plant- they have two salt glands on each leaf base. White mangroves have no visible aerial root system like red and black mangroves. Black mangrove penetrates farthest inland into brackish water and farthest north of the mangrove species. It is native to the coasts of western Africa from Senegal to Cameroon, the Atlantic Coast of the Americas from Bermuda and Florida to the Bahamas, Mexico, the Caribbean, and south to Brazil; and on the Pacific Coast of the Americas from Mexico to northwestern Peru, including the Galápagos Islands. White Mangroves reproduce by small propagules * (embryonic plants) approx. White mangroves are closer to the ocean and produce sweet secretions using nectaries at the base of their leaves. From just a few feet away, dense and much-branching White Mangrove looks like a green wall, but up close you begin seeing distinguishing features such as its three-inch-long (7cm) leaves with rounded or notched tips, and long, roundish petioles jutting from the stem almost at right angles. (discarded of when the levels are too high) - Mangroves can restrict the opening of their stomata. white mangrove are round and the flowers are white. Leaves: The persistent leaves are oppositely arranged and are 1" to 3" long. Bark: Brown to gray, fissured; breathing roots may be present, but not to the extent found in Black Mangrove. for biotopes that allow for the root system to be partially above It is characterized by its narrow rounded crown. Coast Ecosystems unless otherwise noted and should not be Care Information, Scientific Name: Laguncularia These glands are sugar glands called nectaries and they excrete a floral nectar that attracts pollinators. dies as its roots can not be submersed long term. A waxy coating on the leaves of some mangrove species seals in water and minimizes evaporation. Coastal areas can be tricky to landscape. a notched tip. white mangrove is usually found further inland of the red and Black mangroves grow slightly closer to shore than red mangroves and send up thin tubular roots to absorb oxygen and exude salt from their leaves. Flowers & Fruits Each of these mangroves have special characteristics added to the fruits and plants to help increase survival of offspring. Fruits are capsules 20-30 mm diameter, each with one seed which germinates before the fruit falls. The White Mangrove has roundish leaves with little two little bumps on the stem and flask shaped fruit. These glands are sugar glands called nectaries.
