Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Alocasia sinuata
Species Authority: N.E.Br.
Common Name(s):
English Alocasia Quilted Dreams
Alocasia bullata Hort. [nom. inval.]
Taxonomic Notes: Hay (1999) reported that the species is botanically poorly known.  The species was described by Brown in 1885 from cultivated specimens which were believed to have been collected from the Philippines originally.  The species is widely cultivated in the US, Australia and Europe. It can be easily distinguished from other species due to its short height, eight to 10 leaves crowded together and markedly bullate and thickly coriaceous blades.   

Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(ii,iii,v) ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01

Alocasia sinuata is confined to limestone forests of Ilijan (Brgy. Osmeña), Marabot, Samar near the beach area.  The area is not protected and the limestone forests are privately owned by beach resorts.  First class hotels and beach resorts surround the forest. The species is a very beautiful ornamental plant; although during the visit, no collection for ornamental purposes was observed. The conversion of forest to resorts threatens the continued existence of this species in the wild.

Population [top]

Population: A. sinuata was introduced into cultivation in international nurseries and gardens over a century ago, but since then the species has only been recordedonce in the wild at the location in Samar.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology:

A. sinuata is found in limestone forests at very low altitude near the beach.

Systems: Terrestrial

Threats [top]

Major Threat(s):

The major threat to the species is the conversion of the habitat to beach resorts.  During the assessment, collection of the species in the wild was not observed but a few individuals were seen growing in gardens in the area, hence low level collecting may still be an issue..

Conservation Actions [top]

Conservation Actions: No conservation actions are currently in place and hence attempts are required to put some measures in place to ensure the future survival of this species in the wild.
