Concept Reference: Flora of North America Editorial Committee. 2002a. Flora of North America North of Mexico. Vol. 26. Magnoliophyta: Liliidae: Liliales and Orchidales. Oxford Univ. Press, New York. xxvi + 723 pp.
Concept Reference Code: B02FNA26HQUS
Name Used in Concept Reference: Oncidium ensatum
Taxonomic Comments: Flora of North America (2002a) lumps Oncidium floridanum with O. ensatum: studies of O. ensatum "reveal no characters consistent enough to warrant recognizing the Florida populations as a separate taxon." Kartesz (1994) treated them as distinct taxa.

NatureServe Status

Global Status: G4
Global Status Last Reviewed: 23Jun2014
Global Status Last Changed: 06Jun2014
Ranking Methodology Used: Ranked by calculator
Rounded Global Status: G4 - Apparently Secure
Reasons: Oncidium ensatum occurs in southern Florida, the West Indies (Bahamas and Cuba), Mexico, Belize, Honduras, Costa Rica, and Panama (Ames and Correll 1953; Correll & Correll 1982; FNA 2002; McLeish et al. 1995). Extent of occurrence is at least 1, 500, 000 km2.
This species is fairly common (Cuba, Belize) to uncommon (other, Central America) to rare (S1 in Florida) across its range.

Threats are not documented for the range outside of Florida where it is threatened by poaching, non-native plant invasions, fires (wild and prescribed) during the dry season (Gann & Woodmansee 2014). Threats throughout the rest of the range are unknown.

In Florida, numerous populations are extirpated due to changes in hydrology, illegal collection, and habitat loss.

NatureServe Global Conservation Status Factors

Range Extent Comments: Occurs in southern Florida, the West Indies (Bahamas and Cuba), Mexico, Belize, Honduras, Guatemala, Costa Rica, and Panama (Ackerman 2014, Ames and Correll 1953, CICY Herbarium 2010+, Correll and Correll 1982, FNA 2002, Llamacho and Larramendi 2009, McLeish et al. 1995).

Number of Occurrences: Unknown
Number of Occurrences Comments: Rare at the northern edge of its range in southern Florida where there is only one extant occurrence in southern Florida. Approximately 6 sites in Miami-Dade County, 1 in Collier, and 1 in Monroe county are extirpated. The number of occurrences outside of the U.S.A. is unknown. Noted as widespread throughout Puerto Rico (Ackerman 1995).

Noted as uncommon in Central America in the Orchids of Guatemala (Ames and Correll 1953) and noted as uncommon from Mexico to Panama in Flora Costaricensis (Atwood & Mora de Retana 1999) but described as common in the Orchids of Belize (McLeish et al. 1995).

Population Size Comments: A count from 2001, noted 100 plants at Florida occurrence in Everglades National Park.

Number of Occurrences with Good Viability/Integrity: Unknown

Overall Threat Impact: Unknown
Overall Threat Impact Comments: Site in Everglades National Park is threatened by poaching, non-native plant invasions, fires (wild and prescribed) during the dry season (Gann & Woodmansee 2014). Threats throughout the rest of the range are unknown.

Short-term Trend Comments: Since the early 1900's, about 6 sites in three counties in Florida were extirpated, some due to changes in hydrology (Gann & Woodmansee 2014).
