Aloe acutissima
Aloe acutissima
Overview
Aloe acutissima is an accepted species from Madagascar. WCVP currently accepts three subspecies (subsp. acutissima, subsp. itampolensis and subsp. makayensis) and four varieties (var. antanimorensis, var. fiherenensis, var. isaloana and var. itampoloana) within the species. [1]
Distribution
Madagascar [1]
Habitat
Jean-Bernard Castillon & Jean-Philippe Castillon (2010) record the species widely on rocky hills in South-Betsileo. [1] [2]
Diagnostic features
Jean-Bernard Castillon & Jean-Philippe Castillon (2010) describe marked variation, with different forms on different rocky hills. Carter et al. (2011) also report variation in the size of stems, leaves and flowers across the distribution, with higher-altitude plants more robust and lower-altitude plants in drier situations tending to be smaller.

Classification and nomenclature
- Accepted name
- Aloe acutissima H.Perrier [1]
- Publication
- Mém. Soc. Linn. Normandie, Bot. 1: 17 (1926) [1]
- Taxonomic note
- Jean-Bernard Castillon & Jean-Philippe Castillon (2010) list four infraspecific treatments. This database follows the current WCVP accepted hierarchy and retains the 2010 treatment as the historical source view. [2]
- Historical taxonomic view
- The same source states the authors’ view that A. berevoana should be treated as another forest variety of A. acutissima. This is retained as a historical 2010 taxonomic opinion and is not substituted for the current accepted hierarchy used by this database. [2]
