Kingdom Phylum Class Order Family
Plantae Tracheophyta Liliopsida Liliales Aloaceae

Scientific Name: Aloe massawana Reynolds
Taxonomic Notes: The specific epithet refers to plants from the coast of Eritrea, which Reynolds considered to be identical to plants from north of Dar es Salaam. Reynolds thought this latter material was introduced, but further collections suggest the species is native to East African coastal regions, and Carter (1994) suggested that its identity with Eritrean material should be considered with caution. But recent flowering material indicates that this species may well be conspecific with the aloe from Massawana now called (A. eumassawana). It is probable that A. massawana is synonymous with A. kirkii from Zanzibar, but the type material at RBG Kew for the latter is insufficient to confirm this (Carter 1994).

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2009

The extent of occurrence and area of occupancy are small enough for a Vulnerable listing; it is known from only five locations which are severely fragmented and there is continuing decline due to human activities along the coast.

Geographic Range [top]

Range Description:A coastal species found in southern Kenya and northern Tanzania as far south as Dar es Salaam and on a small island near Zanzibar. The northern most collection in Kenya is doubtful, as is any putative collections from Eritrea.
Countries occurrence:
Kenya; Tanzania, United Republic of

Population [top]

Population:Not very common.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:A decumbent succulent herb which grows right on the beach front in the salt spray zone on coral outcrops. Also recorded in sandy soils, in grass and open thickets near the sea shore.
Continuing decline in area, extent and/or quality of habitat:Yes

Threats [top]

Major Threat(s): The habitat is sensitive as it is a zone impacted by human activities (coastal development, etc.). Has attractive flowers so would also be sought by succulent collectors.

Conservation Actions [top]

Conservation Actions: Not known for certain from any protected area. There is a sight record from Mtwara - Mnazi Bay/Ruvuma Estuary Marine Protected area, but the identity of this still needs to be confirmed.
