Black demon flower survives without sunlight in Thailand
Botanists in the dense mountain forests of Thailand’s Thong Pha Phum National Park have discovered a plant that more closely resembles a gothic sculpture than a living organism. Dubbed Thismia daemona, the species earned its name — meaning "demon" — from its striking black flowers and three horn-like appendages. The visual contrast is stark: its inner petals are a deep, matte black, while the outer petals glow with a vibrant orange. A Life Unseen: The Mycoheterotrophic Existence This discovery prompts a fundamental question: how can a plant survive without the very element that defines its nature — photosynthesis? Thismia daemona is a mycoheterotroph. It lacks chlorophyll and thus cannot harness the energy of sunlight. Instead, it spends nearly its entire life underground, functioning as a parasite that siphons nutrients from the mycelium of soil fungi. The only time it emerges into the world is for a few weeks each year, pushing small, lantern-like flowering shoots from the earth. Distinguishing the Demon Flower To determine if this was a known species or an entirely new one, a research team led by Sahut Chatananontarapinta from Prince of Songkla University conducted detailed genetic and morphological analyses. By sequencing its mitochondrial and nuclear DNA, the researchers placed the plant within the Geomitra section of the Thismia genus. While it shares genetic kinship with a species from Borneo (T. betung-kerihunensis), its appearance is closer to the Malaysian species T. limkokthayi. However, the unique, bumpy texture of its black mitre (the fused inner petals) and its distinct club-shaped appendages distinguish it as a separate species.
