|Scientific Name:||Delonix tomentosa (R.Vig.) Capuron|
Poinciana tomentosa R.Vig.
|Red List Category & Criteria:||Critically Endangered (Possibly Extinct) B1ab(iii)+2ab(iii); D ver 3.1|
Delonix tomentosa is listed as Critically Endangered as it is only known from one collection made in 1901, and attempts to find it since have failed. The area it was collected is not found in a protected area and the continuing fragmentation and deforestation of the western dry forest habitat are a cause for concern. In agreement with the IUCN Red List User Guidelines (IUCN Standards and Petitions Working Group 2010), the rating given for D. tomentosa is CR B1ab(iii), D. The species is also tagged as being Possibly Extinct.
|Date last seen:||1901|
|Previously published Red List assessments:|
|Range Description:||D. tomentosa is endemic to Madagascar. It is only known from type specimen collected from the Ankara plateau in the Boina, western Madagascar in 1901 at an elevation somewhere between 100 and 500 m.|

|Population:||Only one subpopulation of D. tomentosa can be estimated by GIS analysis (Rivers et al. 2010). Population numbers, density and trend are unknown.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||D. tomentosa is a deciduous tree 10-15 m tall. It is found within the dry forest especially on limestone (Du Puy et al. 2002). It is thought to be pollinated by moths due to its night opening flowers, white petals with long dark stamens and the upper petal with a narrow tubular nectariferous claw (Du Puy et al. 1995, 2002).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Major Threat(s):||D. tomentosa is only known from the type collection on the Ankara Plateau, where the small fragments of remaining native vegetation are under threat from annual fires (Du Puy et al. 2002, WWF 2001).|
|Conservation Actions:||None known. Further surveys are required to determine if this species is still extant or if it has gone extinct.|
