Marshallocereus is a monotypic genus of flowering plant in the family Cactaceae. The only species is Marshallocereus aragonii that is found in Costa Rica, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua.[2]
Description
[edit]Marshallocereus aragonii is a columnar cactus with dark green shoots that grow up to 5–6 meters tall (rarely exceeding 6 meters) and 12–15 centimeters in diameter. It branches minimally from the base and typically lacks a distinct trunk. The shoots often display a diagonal, light band pattern marking the end of annual growth. The plant features 5–8 rounded ribs, 2–3 cm high, with 1–3 gray central spines (2–3 cm long) and 5–9 shorter marginal spines (up to 2 cm long). The funnel-shaped flowers bloom at night, measuring 6–8 cm in length. They have greenish-brown outer bracts, white inner bracts, and a tubercled, thorn-covered pericarpel.[3]
Distribution
[edit]This species is native to northwestern Costa Rica, El Salvador, Guatemala, Honduras, Mexico (Chiapas), and Nicaragua growing in dry forests at elevations from 50 to 800 meters.
