Anthurium mittermeieri Diaz Jim., M.Cedeño & Pérez-Farr.

• Genus: Anthurium
• Botanical Background: Described in 2022 by Díaz Jiménez, Cedeño‑Fonseca & Pérez‑Farrera, the species honors Michael Mittermeier for his contributions to Central American aroid research

• Geographical Range: Endemic to the slopes of Volcán Tacaná, Unión Juárez municipality, Chiapas, Mexico, at ca. 1900 m elevation.
• Environment: Grows on shaded rock faces in humid montane forest with high annual rainfall and persistent mist; substrate is humus-rich detritus over rock.

Leaves

• Petiole is 51–125 cm long, 6–13 mm diameter, D‑shaped and flattened adaxially

• Geniculum is 3–4.5 cm long, 7.5–9 mm diameter, sometimes tinged red

• Blade is triangular to ovate‑triangular, 49–66 × 30–38 cm, narrowly acuminate apex, broadly lobed base; dark green, glossy adaxially, lighter green below; major veins raised, collective veins 3–13 mm from margin

Inflorescence (Spadix & Spathe)

• Peduncle is 46.5–80.5 cm long, 6.5–10 mm diameter, sulcate, light-pink to yellowish-green
• Spathe is 7.5–14 cm long, 3.3–5.5 cm wide, coriaceous, light green tinged purple, oblong-lanceolate, held at 45° to peduncle

• Spadix is 7.5–13.5 cm long, tapering, tepals light green, pistils pink; flowers rhombic, 1.8–4 × 2.1–4 mm

Growth Habit

• Terrestrial to epipetric, stems up to 40 cm long, 3–4 cm diameter
• Persistent cataphylls 10–15 cm long cover stem

Light Requirements

• Bright, indirect light

• Avoid direct sun to prevent leaf scorch

Watering & Humidity

• Keep medium evenly moist but not waterlogged

• Maintain humidity above 70% to mimic montane cloud forest

Soil & Potting Mix

• Use a well-draining mix of orchid bark, perlite, and peat or coconut coir
• A shallow pot helps prevent water stagnation

Temperature & Fertilizer

• Optimal range 15–25 °C

• Feed monthly during growth with a balanced, diluted fertilizer

Division and Cuttings

• Divide rhizomatous clumps or use stem cuttings with at least one node
• Root in moist, sterile mix under high humidity

Seeds

• Sow fresh seeds on a sterile, moist substrate at 22–25 °C
• Germination typically occurs in 4–8 weeks; ensure high humidity and gentle misting

Typical Issues

• Spider mites, mealybugs, scale, aphids, and thrips

• Prevent root rot by ensuring good drainage and avoiding overwatering

Treatment Recommendations

• Use insecticidal soap or neem oil for pests
• Improve air circulation and reduce moisture for fungal issues
• Apply systemic treatments sparingly if infestations persist

• Unlike most Andiphilum species with orange fruits, A. mittermeieri bears glossy red berries
• It grows sympatrically with other endemic Araceae such as Monstera tacanaensis

• Collectors prize its large, triangular glossy leaves, impressive inflorescences, and rare red fruits
• Its epipetric habit adds rock-garden interest

Wild Population Status

• Known only from a single locality
• Potential vulnerability due to restricted range and habitat specificity
• No IUCN assessment to date

Market Availability

• Extremely rare in cultivation
• Only found in specialized collections or through tissue culture propagation
• Not widely commercialized
