Published illustration: Description Evergreen shrub or small tree 1–10 m high, trunk to 40 cm in diameter. These roots also anchor the plant during the frequent inundation of seawater in the soft substrate of tidal systems. It is found on mudflats and coasts throughout tropical and sub-tropical regions in the Americas. Description The black mangrove is a coastal evergreen tree native to Florida. This species was collected by Banks and Solander at Cooktown in 1770. This species is widespread and common throughout its range.

This may be whitish, a characteristic described in the common name. The three subspecies are shown: Avicennia marina subsp. Mangrove shrub or tree, 1.5-6(-16) m high. 8:2868 (1915); A. marina (Forssk�l)Vierh. Previously this taxon has very widely been confused with A. officinalis L., a closely allied species distinguished by its flowers being 10-15 mm wide when fully expanded. The habit is a gnarled arrangement of multiple branches. 2:37 (1775); A. resinifera Forster f., Pl. Description. 137. Aeg.-Arab.

There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru.

As with other mangroves, it occurs in the intertidal zones of estuarine areas. australasica. Taxonomic notes: APNI* Description: Small tree or shrub up to 9 m high, branches, inflorescences and lower surface of leaves greyish or silvery; pneumatophores numerous and projecting from the shallow lateral roots. The roots are shallow and send up a large number of pencil-shaped pneumatophores.These aerial roots help with gas exchange and also play an important part in the exclusion of salt from the plant's vascular system. It contains mangrove trees , which occur in the intertidal zones of estuarine areas and are characterized by its "pencil roots", which are aerial roots . The following relates to distribution of this ecosystem type within the Central Queensland mapping area: australasica is the world's southernmost mangrove, being reported from the south-eastern tip of Australia near Melbourne, and from New Zealand near Auckland. As with other Avicennia species, it has aerial roots (pneumatophores); these grow to a height of about 20 centimetres, and a diameter of one centimetre. Excreted salt on the underside of a Avicennia marina var. It has smooth light-grey bark made up of thin, stiff, brittle flakes. These allow the plant to absorb oxygen, which is deficient in its habitat. The species can tolerate high salinity by excreting salts through its leaves. The habit is a gnarled arrangement of multiple branches. Another variety, Avicennia marina var. Description: Small tree to 6m+ high; bark is smoth & grey in colour. Description. Description. Fl. Bot.
