Tectaria minima Underw.:
United States (North America)

United States

Origin: Native

Regularity: Regularly occurring

Currently: Present

Confidence: Confident

Type of Residency: Year-round

Global Range: Florida; Mexico in Yucatan; West Indies in Bahamas, Greater Antilles (FNA 1993); Cuba (Lakela and Zong 1976).

The hybrid between Tectaria fimbriata and T . coriandrifolia is T . × amesiana A. A. Eaton. Although intermediate between the two parents, the hybrid will lead to T . fimbriata in the key. The hybrid may be distinguished from T . fimbriata by scattered hairs on abaxial surface of petioles and misshapen spores.

Stems horizontal, short-creeping. Petiole straw-colored, 1--3 times length of blade, hairs absent abaxially, pubescent adaxially, base scaly; scales lanceolate to linear, 1--3 × 0.3--0.5 mm. Blade deltate to pentagonal, 1-pinnate or ternately lobed, 5--10 × 3--7 cm. Rachis and costae pubescent abaxially. Pinnae absent or 1(--2) pair, or blade shallowly pinnatifid, 4--7 cm, base rounded, without proliferous buds in axils. Areoles rarely with included veinlets. Indusia peltate. 2 n = 80.

Aspidium fimbriatum Willdenow, Sp. Pl. 5(1): 213. 1810; A. minimum (L. Underwood) Clute; A. trifoliatum (Linnaeus) Swartz var. minimum Clute; Sagenia lobata C. Presl; Tectaria lobata (C. Presl) C. V. Morton; T. minima L. Underwood

Comments: Solution holes and sinkholes in oolitic rock within tropical hammock forests in southern Dade County south of Modello. Bahamas: Banana holes, ledges in shady places, especially in coppices (Correll and Correll 1982); occasionally in sun at 0 meters (FNA 1993).

Sinkholes, on shaded ledges or occasionally in sun; 0 m; Fla.; Mexico in Yucatán; West Indies in Bahamas, Greater Antilles.

Note: For many non-migratory species, occurrences are roughly equivalent to populations.

Reasons: Occurs in a restricted habitat but distribution is fairly broad and precise rangewide abundance is unknown. Locally abundant in some Dade County hammocks. Common in Jamaica, West Indies, Bahamas, Yucatan (Lellinger 1985).

Comments: Threatened primarily by casual collectors.

Comments: Kartesz (1994) and Flora of North America (1993) include Tectaria lobata in T. fimbriata. The citation given for T. fimbriata is Bradea 5:386. 1990. Unknown whether T. lobata is a more narrow circumscription being included in a larger one for T. fimbriata.
