PINELAND LANTANA<br />

<strong>Lantana</strong> <strong>depressa</strong> Small <strong>var</strong>. <strong>depressa</strong><br />

Synonyms: <strong>Lantana</strong> ovatifolia Britton<br />

forma parvifolia Moldenke<br />

<strong>Lantana</strong> ovatifolia Britton <strong>var</strong>. reclinata R.W. Long<br />

Family: Verbenaceae (verbena)<br />

FNAI Ranks: G2T1/S1<br />

Legal Status: US–Mgmt Concern FL–Endangered<br />

Wetland Status: US–none FL–UPL<br />

Gil Nelson<br />

Field Description: Low, mat-forming shrub. Leaves 2 inches long, 1 inch<br />

wide, opposite, oval to lance-shaped, toothed, with wedge-shaped bases,<br />

blades folded up along the midvein. Flowers bright yellow-gold but fade to<br />

orange with age (photo, lower right), 15 - 20 flowers in dense, flat-topped<br />

clusters. Fruit fleshy, shiny black.<br />

Similar Species: The common, exotic landscape lantana (<strong>Lantana</strong> camara)<br />

has squared-off leaf bases, orange or multi-colored flower heads, and thorny,<br />

erect branches. Landscape culti<strong>var</strong>s such as “<strong>Lantana</strong> Gold” and “Gold<br />

Rush” resemble the native <strong>var</strong>ieties but are of uncertain parentage and<br />

should not be considered native. Button sage (<strong>Lantana</strong> involucrata) has<br />

white, yellow-centered flowers and yellowish stems.<br />

Related Rare Species: Two yellow-flowered <strong>var</strong>ieties of pineland lantana<br />

are similar except for growth form: Sanibel lantana (<strong>Lantana</strong> <strong>depressa</strong> <strong>var</strong>.<br />

sanibelensis) has erect branches to 3 - 9 feet tall. <strong>Florida</strong> lantana (<strong>Lantana</strong><br />

<strong>depressa</strong> <strong>var</strong>. <strong>floridana</strong>) has lax or arching stems to 6 feet tall.<br />

Pineland lantana <strong>Lantana</strong> <strong>depressa</strong> <strong>var</strong>. <strong>depressa</strong><br />

Habitat: Pineland lantana: pine rocklands of southern Dade County,<br />

especially Everglades keys. Sanibel lantana: dunes, coastal grasslands, and<br />

sandy inland ridges. <strong>Florida</strong> lantana: dunes and sandy inland ridges.<br />

Best Survey Season: Flowers all year.<br />

Range-wide Distribution: Pineland lantana: endemic to Dade County, FL.<br />

Sanibel lantana: endemic to SW coast of FL. <strong>Florida</strong> lantana: endemic to SE<br />

coast of FL.<br />

Conservation Status: Although found on many conservation areas, all 3<br />

<strong>var</strong>ieties are threatened by exotic species invasion and by “genetic swamping”<br />

through hybridization with <strong>Lantana</strong> camara.<br />

Protection & Management: Where native <strong>var</strong>ieties occur with <strong>Lantana</strong><br />

camara, removal of this exotic species is urgent. Burn pine rocklands every<br />

2 - 3 years. Protect coastal habitats from development.<br />
