Anthurium minarum Sakur. & Mayo

• Genus: Anthurium
• Botanical Background: Described as a new species by Cássia M. Sakuragui and Simon J. Mayo in 1999 (Feddes Repertorium 110: 535). The epithet minarum honors the Brazilian state of Minas Gerais, where the type specimens were collected.

• Geographical Range: Endemic to the montane campo rupestre vegetation of southeastern Brazil—specifically Minas Gerais, Rio de Janeiro, and São Paulo states.
• Environment: Grows epiphytically on trees and rocky outcrops in a seasonally dry tropical biome, experiencing high humidity during the wet season and well‑drained conditions during dry spells.

Leaves

• Peduncle 16–73 cm long, green to reddish‑purple

• Spathe 2.3–15.5 × 0.4–1.7 cm, linear to oblong-linear, green to reddish-purple.

• Spadix 2.6–18 × 0.3–0.8 cm, reddish‑purple before anthesis, darkening with age; sessile or on a 1–2 mm stipe 

Inflorescence (Spadix & Spathe)

• Peduncle 16–73 cm long, green to reddish‑purple

• Spathe 2.3–15.5 × 0.4–1.7 cm, linear to oblong-linear, green to reddish-purple.

• Spadix 2.6–18 × 0.3–0.8 cm, reddish-purple pre-anthesis, darkening with age; sessile or on 1–2 mm stipe.

• Likely pollinated by small flies or beetles, as is typical in Anthurium

Growth Habit

• Acaulescent, rosulate epiphyte with a short, fibrous stem enveloped by persistent cataphylls and adventitious roots
• No true tubers

Light Requirements

• Bright, indirect light

• Protect from direct midday sun to prevent leaf scorch

Watering & Humidity

• Keep substrate evenly moist, allowing the top layer to dry slightly between waterings
• Maintain humidity above 60 %

Soil & Potting Mix

• Use a well‑draining, airy mix (e.g., orchid bark, peat moss, perlite) to mimic its natural epiphytic substrate

Temperature & Fertilizer

• Ideal range 18–25 °C
• Feed monthly during active growth with a balanced, water‑soluble fertilizer at half strength

Division and Cuttings

• Divide mature clumps ensuring each section has several leaves and adventitious roots
• Repot divisions into fresh, airy mix

Seeds

• Berries yield ellipsoid seeds (2–2.5 mm)
• Sow fresh on sterile, moist substrate under warm, humid conditions
• Germination can take several weeks

Typical Issues

• Mealybugs, aphids, thrips, scale, and spider mites
• Inspect new plants, maintain cleanliness, and ensure proper air circulation

Treatment Recommendations

• Dislodge pests with a strong water spray

• Apply horticultural soaps or neem oil for light infestations

• Use pyrethrin‑based or malathion/dimethoate sprays for stubborn mealybugs

• Isolate affected plants and monitor regularly

• Characteristic component of Brazil’s campo rupestre ecosystems
• Enriches the diversity of epiphytic flora in seasonally dry montane habitats

• Sought by aroid collectors for its elegant, narrow leaves with dark punctations and striking elongated reddish‑purple spathes

Wild Population Status

• Not yet evaluated by the IUCN

• Habitat conversion in southeastern Brazil may threaten wild populations

Market Availability

• Rare in general trade

• Typically sourced from specialist aroid nurseries or enthusiast plant exchanges
