Vitex rotundifolia. While the plant is a seashore obligate, it grows over a wide latitude range. Found In. Recovery Plan for seabeach amaranth (Amaranthus pumilus) Rafinesque. Likely due to the wide range over which V. rotundifolia is native, the plant has acquired a host of common names. Journal of Plant Biotechnology, 6(3):165-169. [33] Fruits are covered with thick coatings of hydrophobic cuticular alkanes allowing them to resist water penetration for extended periods. -> Vitex negundo L. var. Four stamens are didynamous and extend beyond the corolla tube (measuring 9 to 10 mm). St. Louis, Missouri and Cambridge, Massachusetts, USA: Missouri Botanical Garden and Harvard University Herbaria. Genetics Leaves [3] Plants grow down to the ocean waves themselves. Common Name(s): Beach vitex, roundleaf chastetree. Leaf blades small, about 1.7-4.5 x 0.8-3 cm, petioles about 0.5 cm long. The leaf characteristics are intermediate between the two parent plants while the blue-purple flower color of the parents persists in the hybrid. Legislative Information System: Virginia Administrative Code. In southeastern USA, two small Vitex tree species preceded the naturalization of V. rotundifolia, both having escaped horticultural planting.

University of Florida Herbarium Collections Catalog. Voucher specimen data from the Michael Cousens Herbarium. More recently, it was imported to the eastern United States where it has become a seashore invasive. Populations on the Gulf of Mexico shorelines of northwestern Florida and Southern Alabama are among the more recent disjunct occurrences. On beaches of southeastern USA, seedlings of V. rotundifolia might be mistaken for the native silver-leaf croton, (Croton punctatus) (Gresham 2015). Patterns in germination of this and related species (Murren et al., 2014) suggest the influence of physical and physiological dormancy in the seed (Cousins et al., 2010b).

[39] Large genetic variation between populations was observed with lower variation within populations, and plants within 20 m of each other were closely related. After a period of 6 months, all stems are removed. Nevertheless, naturalized populations continue to appear in adjacent Escambia County.

Bird dispersal is highly unlikely as there is no fleshy fruit reward; water dispersal is the most likely dispersal means capable of enabling dispersal over such long distances. [3] The specific epithet, rotundifolia, is derived from the Latin rotundus, which means "round, spherical", and folium, meaning "leaf.” This is a reference to the rounded character of the leaves. Sorting Vitex names. Triclopyr has also been successful when used on seedlings and small-caliper resprouts (Cousins et al., 2010b). Vitex rotundifolia, the roundleaf chastetree or beach vitex is a species of Vitex that is native to seashores throughout the Pacific. McAvoy WA, 2011. Mabberley DJ, 2008.

The most common variety of vitex used medicinally is chaste tree, which produces chasteberry (Vitex agnus-catus), a small brown berry fruit about the size of peppercorn.

Multiple hybrids between Vitex agnus-castus and Vitex rotundifolia have been developed at the Chicago Botanic Garden. Nelson G, 1996. Clonal growth and occasional self-starting, adjacent seedlings were observed to contribute to the unexpectedly rapid expansion of planted patches. July, 2012. [2] New stems are green, square and fleshy initially before maturing brown and woody. University of West Florida, 2015. Older, large-diameter stems are covered with heavily fissured bark. National Herbarium of Victoria - Royal Botanic Gardens Victoria., http://www.rbg.vic.gov.au/, MO, 2016. al, 2009), but has only been known to escape cultivation, grow aggressively, and invade natural habitats along sandy, energy driven coastlines. The orbicular leaves of seagrape, however, are 10 times the size of V. rotundifolia (Nelson, 1996) besides having red veins, cordate, hefty bases and an overall smooth, leathery patina. The generic epithet, Vitex, is derived from the Latin viere, meaning “to bind or twist” in reference to the rope-like stems produced by some species in the genus. Beach vitex is a perennial that grows throughout the summer months in temperate and tropical areas of the Pacific. Ocean currents are believed to be responsible for the pervasiveness of V. rotundifolia throughout the Pacific. Common names include "chaste tree" or "chastetree", traditionally referring to V. agnus-castus but often applied to other species as well.

Vitex is a genus of about 250 species of shrubs and trees, of which the Vitex agnus castus (chaste tree) and Man Jing Zi of Vitex trifolia are members. [42], Vitex rotundifolia fruits have been shown to transfer cuticular alkanes to the sand substrate. http://www.flmnh.ufl.edu/herbarium/cat/, FLEPPC, 2014. (2007), V. rotundifolia has been protected as a Threatened species in Shiga Prefecture of Honshu, Japan, and was also included in the List of the Important Wild Plants for Conservation in China in 1989.
