Aloidendron eminens (Reynolds & P.R.O.Bally) Klopper & Gideon F.Sm.
Eminent aloe tree
Aloidendron eminens is an arborescent species from the semi-arid highlands of the Horn of Africa, originally described as Aloe eminens by Reynolds and Bally in 1958. It grows in the mountainous regions of Somalia and Ethiopia at altitudes of 500–1800 metres, where conditions are semi-arid with seasonal rainfall. It is one of the least-studied species of the genus, with a restricted natural range and few documented ex situ collections. Its bearing is imposing, reaching 6–9 metres tall, with a robust trunk and dense crown of terminal rosettes. Flowers are bright red-orange, produced in large inflorescences during the dry season.

Propagation Strategy
- 1 Obtain fresh seeds from certified botanical collections.
- 2 Sow in pure mineral substrate at 27–32 °C with very low humidity.
- 3 Keep in propagator until seedlings are 3–5 cm tall.
- 4 Gradually acclimatise to full-sun conditions.
D
Watering too frequently.
Every 4–5 years in juveniles.
Once a year in spring, very diluted mineral fertilizer (NPK 5-10-10).
Uses & Applications
Precautions / Toxicity
No published toxicological data. As a precaution, treat as moderately irritating (arborescent aloe latex).

"Aloidendron eminens is one of the most data-deficient species in the genus. Most herbarium records date from the 1950s–1970s, before the armed conflicts in Somalia. An updated conservation assessment and establishment of ex situ collections in botanical gardens are urgently needed."
