Taxonomy [top]

Kingdom Phylum Class Order Family
Plantae Tracheophyta Magnoliopsida Euphorbiales Euphorbiaceae

Scientific Name: Euphorbia ambovombensis Rauh & Razaf.
Taxonomic Notes: The taxonomic status is dubious, and its synonymy with earlier varieties of E. decaryi has to be considered.

Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Annotations:

Assessor(s): Haevermans, T.
Reviewer(s): Rajeriarison, C., Labat, J.N., Lowry, P. & Randrianjohany, E. (Madagascar Plants RLA)
Justification:
Restricted to the Ambovombe area of Madagascar. Rauh in his original paper states that this species was found in other close areas and Tulear, however, this cannot be ascertained and a thorough study is required.
