Stigma lobes (0.2–) 0.4– 0.7 mm long. Fruit ovoid to broadly elliptic to obovoid, usually grayish (rarely black) when dry, 12–32 mm long, 9–25 mm across at widest expanse, pubescent with antrorsely appressed eglandular trichomes to 0.7 mm long (especially when less mature) and scurfy (especially when more mature).

PHENOLOGY.— Flowering: throughout the year; fruiting: April–January (especially in August, and likely throughout the year).

DISTRIBUTION AND HABITATS.— Southern North America (southeastern USA and Mexico), Bermuda, West Indies, Central America, South America ( Brazil, Colombia, Ecuador [including Galapagos Islands], French Guiana, Guyana, Peru, Surinam, and Venezuela), and tropical western Africa (see Daniel and Figuerido [2009] for distributional information on African plants, which often have been referred to as A. africana P. Beauv. ). Figure 2 View FIGURE shows the generalized distribution of this species in North America and Mesoamerica. Plants occur in/on tidal flats, beaches, coastal mangrove swamps (mangals), salt marshes, sand dunes, and coastal grasslands and savannas at elevations at or near sea level. Common associates include Allenrolfea occidentalis , Batis maritima , Bravaisia berlandieriana , Coccoloba uvifera , Conocarpus erectus , Distichlis litoralis , D. spicata , Echinochloa polystachia , Frankenia palmeri , Laguncularia racemosa , Maytenus phyllanthoides , Rhizophora mangle , Salicornia biguelovii , S. virginica , Scaevola plumieri , and Spartina alterniflora .

Avicennia germinans is the most widely distributed species of Avicennia in the New World. Its northern distributional limit there is in Bermuda (ca. 32°20ʹN; Lacerda et al. 2002), where another true mangrove, Rhizophora mangle L. also attains the northern extent of its distribution; these occurrences are the northernmost of true mangroves. The northernmost occurrence of A. germinans on the Atlantic Coast of North America is in northern Florida (St. Johns County, 30°06.618ʹN, 081°22.303ʹW, Williams & Eastman s.n. at USF). On the coast of the Gulf of Mexico the northern extent of the species extends as far as the Bay St. Louis, Mississippi (Hancock or Harrison county, ca. 30°2ʹN, Sanger s.n. at NY).

Of the three true mangroves that are common on the American mainland ( A. germinans , Laguncularia racemosa , and Rizophora mangle ) A. germinans is the northernmost in distribution. Its northern limit in North America appears to be determined by the frequency and duration of subfreezing temperatures, which can kill the above-water parts of the plants or cause mortality (Sherrod and McMillan 1985; Cavanaugh et al. 2014). Tomlinson (1986) noted a close correlation of the limits of the distributions of mangroves with the 24° isotherm of sea surface temperatures. A decade later Rützler and Feller (1996) indicated that like corals, mangroves cannot survive where an average water temperature falls below about 23° C. In recent decades, freeze-free winters have led to an expansion of A. germinans into salt marshes at the northern extremes of its range in the southern United States ( Guo et al. 2013). A poleward expansion of the distributional range of A. germinans in southern North America, likely correlated with warmer winter temperatures and less extreme freezes, was recently noted by Cavanaugh et al. (2014).

In the United States, plants have been documented from most of the coastal counties in Florida (except for most of those in the panhandle on the Gulf Coast in the northwestern portion of the state), rarely reported from at least two of the three coastal counties in Mississippi (e.g., Moldenke 1960; Scheffel et al. 2014; the locality cited for Mississippi by Lowe in 1921, Door Point, is in Louisiana), and documented from seven coastal parishes in Louisiana. In Texas the species has been collected along the Gulf Coast from Jefferson County near the Louisiana border intermittently southward to Cameron County on the Mexican border. Although it likely occurs (or occurred) in all coastal counties of Texas, based on specimens noted below and in literature reports ( Turner et al. 2003 and pers. comm. in 2010 from updated but unpublished maps; Rosen and Zamirpour 2014), it has been collected in Aransas, Brazoria, Calhoun, Cameron, Galveston, Jackson, Jefferson, Kleberg, Nueces, Refugio, San Patricio, and Willacy counties. Sherrod and McMillian (1981, 1985) discussed the distributional history of mangroves, including A. germinans , in Texas and in the northern Gulf of Mexico. The species has not been reported from the Gulf coast of Alabama (e.g., Kral et al. 2011).

Avicennia germinans is known from all 16 coastal states of Mexico (occurring along the Gulf of Mexico, Caribbean Sea, Pacific Ocean, and Gulf of California). The species reaches its northern extent in western Mexico along the Gulf of California in Sonora (Puerto Lobos, lat. 30°15ʹN; Felger et al. 2001) and its northern extent on the Pacific coast in Baja California Sur (ca. lat. 26°N; Turner et al. 1995). Distribution along Pacific coast of North America does not extend as far northward as that along the coasts of the Gulf of California, Gulf of Mexico, and the Atlantic Ocean likely because of upwelling of cold waters off the western coast of the peninsula of Baja California and California that limits their northward spread. Turner et al. (1995) discuss the distributions and probable environmental factors effecting them for this species in regions around the Gulf of California.

In Central America to the south of Belize, the extent of mangrove communities and the abundance of A. germinans are better developed along the Pacific than the Caribbean coast. Indeed no specimens have been seen from the Caribbean coast of Costa Rica, although A. germinans has been reported from the mouth of the Río Moín, north of Puerto Limón ( Zamora et al. 2004). In South America, as in North America, A. germinans has a broader distribution on the Atlantic than on the Pacific coast. Lacerda et al. (2002) indicated that the southernmost occurrences of A. germinans in South America are in northwestern Peru (Río Piúra, ca. 5°32ʹS) on the Pacific coast and in southeastern Brazil (Atafona, ca. 21°37ʹS) on the Atlantic coast. Like the northward limit of this species on the Pacific coast of North America, the southern distributional limit of A. germinans along the western coast of South America in Peru appears to have a similar cause due to the cold waters of the Humboldt Current and upwelling there ( Lacerda et al. 2002).

NOMENCLATURE.— The synonymy provided above is based on types from North America and Central America or names sometimes applied to plants from these regions. Additional synonyms were listed by Moldenke (1960, 1973). Based on information provided by Stearn (1958), authorship of the combination A. germinans often has been attributed to “( L.) Stearn” (e.g., Tomlinson 1986; Jarvis 2007; Daniel and Figueiredo 2009). In his letter to D. Ward (17 April 1962 attached to a specimen in FLAS), Stearn indicated that the correct name for the black mangrove is A. germinans ( L.) L., a case subsequently made by Compère (1963), and now widely accepted.

The lectotype of Bontia germinans at LINN also has inflorescence internodes similar to those of A. bicolor (i.e., ca. 4– 4.5 mm long near midspike). From the image of this specimen, I have not been able to discern other diagnostic characters used here to distinguish these species. Thus, I am unable to confirm to which species it pertains.

Moldenke (1960) noted that the types of A. nitida and A. tomentosa are both Herb. Jacquin s.n. specimens at BM, which he annotated as such in 1936. Images of both of these very sparse specimens have been seen, and based on what is visible and available, they likely conform to A. germinans .

Although no specimen was designated as the type of A. floridana Gand. , Gandoger’s herbarium is at LY in France, and it is possible that the holotype is there; specimens of the type number at F, MO, Cornell, NY, and US were cited by Moldenke (1960), but he did not indicate where the holotype was located .

USES.— Firewood ( Mexia 1008; García B. 486); construction materials ( García B. 486); and used by natives for diseases of the throat (Choussy 1593). Additional construction, medicinal, and food uses of the species were provided by Moldenke (1960), Burkill (1985), Cheatham et al. (2000), and Alvarez C. (2008).

CONSERVATION.— The black mangrove is a widespread and often an abundant shrub or tree of tropical and subtropical shorelines and near coastal habitats where it is an important (often dominant) constituent of mangrove communities. Its conservation status was assessed as Least Concern ( LC) by Ellison et al. (2010).

DISCUSSION.— This species is readily distinguished by the combination of its scurfy young stems, densely spicate (headlike) inflorescences, bilaterally symmetric flowers with internally pubescent corolla lobes ( Fig. 3A View FIGURE ), styles usually conspicuously elongating near the end of anthesis or shortly thereafter as the fruits begins to form, and the grayish fruits (when dry; Fig. 3D View FIGURE ).

Rare individuals from Mexico (e.g., Martínez s.n. from Baja California Sur at MEXU; Rico-Gray 95 from Yucatán at UC) have remote nodes (to 7 mm distant, as in A. bicolor ) near the midpoint of the spikes, but show their affiliation to A. germinans by their internally pubescent corolla lobes, scurfy pubescent young stems, trichomes of the rachis to 0.5 mm long, and thecae 0.8 mm long.

The fragrant flowers of Avicennia germinans are commonly visited by honeybees, and they are reputed to be an excellent source of honey. Corollas are often noted to be 10–20 mm long (e.g., Moldenke 1960; Tomlinson 1986). My observations concur with those of Gibson (1970), who indicated that she had seen none more than 8.5 mm in length.

Morphological variation is considerable in this species, especially with respect to habit and leaf size and shape. For example, although it is commonly a sizable tree in portions of its range, A. germinans becomes a dwarf shrub at the northern extent of its range in the Gulf of Mexico (Sherrod and McMillan 1985). Moldenke (1960) discussed variation in this species with respect to these and other attributes.

In a letter to Paul Standley dated 19 February 1938 (attached to Brenes 12222 at F), Moldenke indicated that A. tonduzii could be “most easily” distinguished from A. germinans (as A. nitida ) by the size of the flowers. Indeed some of the specimens cited and/or annotated by Moldenke as A. tonduzii have calyces (2–2.5 vs. 2–4) and corollas (3.5–5 vs. 4–8) that are shorter than most specimens treated as A. germinans . Subsequently, Moldenke (1960, 1973) distinguished A. tonduzii from A. germinans on the basis of its short (shorter than the stamens) style (vs. style exserted from the calyx when corolla is shed, surpassing the stamens) and leaf blades mostly elongate-oblong, 3– 5 times as long as wide (vs. lanceolate or lance-oblong to elliptic or obovate, usually <3 times as long as wide). Elongate styles are evident on the holotype of A. tonduzii at BR (and on isotypes at BR and US). The other putative distinguishing characters of A. tonduzii overlap those of A. germinans when plants from throughout the ranges of both species are considered. Tomlinson (1986) considered A. tonduzii as a narrow-leaved variant of A. bicolor and treated the name as synonymous with that species. Others have followed Tomlinson’s influential account, and A. tonduzii has been recognized as a distinct species in some relatively recent literature (e.g., Lacerda et al. 2002).

In the southern Caribbean region and along the Atlantic coast of South America, the distribution and taxonomy of A. germinans become entangled with those of A. schaueriana Stapf & Leechman ex Moldenke. Stearn (1958) distinguished S. schauerana from A. germinans by the characters in the following couplet:

1a. Leaves mostly acute at tip; corolla lobes tomentose on both sides; style elongate......................................................................... A. germinans

1b. Leaves mostly rounded at tip, sometimes acute; corolla lobes glabrous internally, tomentose externally; style very short, the stigma nearly sessile.................... A. schaueriana

Leaf tips are variable in A. germinans . While length of the style might be somewhat dependent on floral stage and pollination, it appears likely that styles of A. schaueriana , like those of A. bicolor , do not elongate (or at least not to the extent) as in A. germinans . Like A. germinans , A. schaueriana has crowded inflorescences, but pubescence of the corolla lobes would appear to be a useful character for distinguishing these species.
