Schizocasia sanderiana (W. Bull) Engl.
|Taxonomic Notes:||The species was first described by W. Bull in 1884. It can easily be distinguished from the rest of the Alocasia species by its deeply undulate to subpinnatifid margins and white veined leaves.|
|Red List Category & Criteria:||Critically Endangered B1ab(ii,iii,v) ver 3.1|

The species is found in two locations, namely Bukidnon and Misamis Occidental (Mindanao Island). The population is confined to secondary and primary forest at lower elevations. Both locations are protected areas, however, part of Mt. Malindang Range is now being logged by indigenous and local people. In Bukidnon, the population of A. sanderiana was found growing in the Almaciga Reforestation Project area. This place is frequented by local tourists who visit the waterfalls in the area.
Occurs on Mindanao Island (Philippines) in Misamis Occidental (Mt. Malindang) and Bukidnon Provinces (Impalutao Reforestation Project) at 777 m asl (08º15'190'' N and 125º02'135'' E).

|Population:||Alocasia sanderiana is confined to two locations: Mt. Malindang Range in Misamis Occidental and Impasug-ong, Bukidnon, but no information on population size is available.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:|
Found in primary and secondary forest at low altitudes.
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||Alocasia sanderiana is used as ornamental plant because of its colourful and enduring foliage. It is also reported that the species is used by the natives to treat headaches. Fifty percent of the global population is utilized.|
|Major Threat(s):||Agricultural expansion (kaingin) and associated increased exploitation are the main threats to A. sanderiana at Mt. Malindang Range. In Bukidnon, the population is at risk from recreational activities; the area is often visited by local tourists due to the presence of water falls and swimming pools. Plants are collected for ornamental and medicinal use.|
|Conservation Actions:||Both locations were declared as protected areas but the implementation is very poor.|
|Errata reason:||Assessment edited to correct serious formatting issues.|
