Lophophora diffusa, commonly known as false peyote, is a species of plant in the family Cactaceae and one of the species in the Lophophora genus. It is endemic to Mexico in the outskirts of Querétaro.[4] This species contains zero to trace amounts of mescaline. Instead, pellotine is the principal alkaloid - the psychoactive effects of which are comparatively minimal. The species name diffusa refers to the flat tubercles that are outspread without the plant having prominent ribs.[5]
Description
[edit]Lophophora diffusa typically grows as a solitary plant or in groups. Its yellow-green, soft, and somewhat flattened succulent stems reach heights of 2–7 cm and diameters of 5–12 cm. The podaria are rarely elevated, but are broad and flat. The plant lacks ribs, and its wide, flat cusps have small areoles (2–3 mm) with no spines. It has a broad, shallow, tuber-like root, and tufts of hair are unevenly distributed. The flowers are white to slightly pink or yellowish-white, measuring 1.3–2.2 cm in diameter.[6]

Distribution
[edit]This species is the southernmost representative of the genus Lophophora, thriving in limestone soils within a small area of approximately 775 km² between Vizarrón, Bucareli, and Tolimán in Querétaro, Mexico, with minor occurrences in Hidalgo. Its natural habitat is semi-deserts on slopes and river beds, and under the shade of various shrubs and nurse plants such as Larrea tridentata and Senegalia sororia.[5][7] It grows at altitudes of 1,000–2,000 meters above sea level, forming isolated and self-regulated populations in the Estórax River depression.[8] It is considered vulnerable due to a very small distribution range, small population of less than 3,000 individuals, and illegal collecting. It is collected illegally by people seeking peyote, and as an ornamental plant.[3]

Taxonomy
[edit]Originally described as Lophophora echinata var. diffusa by Léon Croizat in 1944, it was elevated to species level in 1967 by Helia Bravo Hollis. The epithet diffusa derives from Latin, meaning "indistinct," referencing the plant’s low, flat, and barely noticeable warts.
