Myrtillocactus eichlamii is a species of Myrtillocactus found in Guatemala.[1]
Myrtillocactus eichlamii grows tree-shaped with upright, striking blue-green to deep green, glaucous shoots and forms a distinct trunk. It has 6 blunt ribs with large, gray areoles spaced up to 2 centimeters apart. The central spine can reach up to 7 centimeters long, while the approximately 5 marginal spines are shorter and swollen at their base.
The creamy white flowers are 4 centimeters long and 3.5 to 5.5 centimeters in diameter, with a very short flower tube. The spherical, purple to red fruits are edible and covered with a whitish wax.[2]
Myrtillocactus eichlamii is widespread in Guatemala.
The species was first described in 1920 by Nathaniel Lord Britton and Joseph Nelson Rose.[3] The specific epithet eichlamii honors the German cactus collector Friedrich Eichlam.
