Scientific Name: Tetramolopium consanguineum subsp. consanguineum
Parent Species:
-
Taxonomic Source(s): Wagner, W.L., Herbst, D.R. and Lorence, D.H. 2005 onwards. Flora of the Hawaiian Islands website. Available at: botany.si.edu/pacificislandbiodiversity/hawaiianflora/index.htm.
Identification information:
Erect shrubs 50-200 cm tall. Leaves linear-oblanceolate, 13-60 mm long and 1.5-4.5 mm wide. Flower heads 9-40 in congested inflorescences. Rays white or pink. Disk florets maroon or purplish brown.
Tetramolopium consanguineum (A. Gray) Hillebr. , Fl. Hawaiian Isl. 199. 1888.
Type Information
Vittadinia consanguinea A. Gray , Proc. Amer. Acad. Arts 5: 120 1861.
Kaua`i: mountains. 1840. U. S. Expl. Exped. s.n..
Lectotype [US]. Lectotypified in Sherff. Bernice P. Bishop Mus. Bull. 135: 19. 1935.
Note: Additional syntype: Hawai`i, Waimea, U. S. Expl. Exped. s.n. (GH, NY). Lowrey considered the US sheet the holotype, but since Gray cited collections from both Hawai`i and Kaua`i, they are all syntypes and Sherff's treatment is taken as a lectotypification.

Assessment Information [top]
Red List Category & Criteria: Extinct ver 3.1
Year Published: 2016
Date Assessed: 2016-07-06
Assessor(s): Clark, M.
Reviewer(s): Walsh, S.
Contributor(s): Nyberg, B. & Wood, K.
Justification:
Tetramolopium consanguineum subsp. consanguineum is assessed as Extinct, not having been seen since 1978 when Tim Lowry apparently collected seed from a cultivated individual which was collected by Derral Herbst (6146; NTBG Living Collections Database 780297). This taxon was undoubtedly impacted by the same threats that affect other native species in the same mountain areas, which include rats, goats, pigs and a whole large suite of non-native, invasive plant species.
Geographic Range [top]
Range Description: Last seen in 1978, and before that in 1868, Tetramolopium consanguineum subsp. consanguineum was endemic to the island of Kauaʻi. It is now extinct. The other subspecies, T. consaguineum subsp. leptecophylla, occurred in the Pohakuloa area of the island of Hawaiʻi, is rare, and may also be extinct.
Countries occurrence:
Regionally extinct:
United States (Hawaiian Is.)

Population [top]
Population: Tetramolopium consanguineum subsp. consanguineum is recorded as having been collected on Kauaʻi in 1978 (National Tropical Botanical Garden, Accession 780297), and before that, not since 1868 when the Type collection was made in "Kauaʻi mountains." It is believed to be extinct.
Additional data:
♦ Number of mature individuals: 0

Continuing decline in area, extent and/or quality of habitat: Yes
Threats [top]
Major Threat(s): No specific information is available about threats to this taxon. However, it was undoubtedly impacted by the same threats that affect other native species in the same mountain areas, which include rats, goats, pigs and a whole large suite of non-native, invasive plant species.
Conservation Actions [top]
Conservation Actions: This species had not been listed by the U.S. Fish and Wildlife Service under the Endangered Species Act and is now extinct.
