Anthurium queirozianum Nadruz

• Genus: Anthurium
• Botanical Background: Described by Nadruz, this species has been the focus of detailed botanical studies that have helped distinguish it from similar Anthurium species. Its identification reflects advances in modern taxonomy and botanical exploration of South American flora.

• Geographical Range: Native to the tropical regions of South America, Anthurium queirozianum is found in humid, shaded forest environments, often within lowland and mid-elevation rainforests.
• Environment: Thrives in environments with high humidity, stable warm temperatures, and soils rich in organic matter; typically grows in well-draining conditions under a dappled forest canopy.

Leaves

• Heart-shaped
• Glossy with prominent venation
• Offering a dark green appearance that may feature subtle bronzy hues

Inflorescence (Spadix & Spathe)

• A vibrant spathe, often displaying shades of red or burgundy
• Spadix serves as the central structure
• Inflorescence is visually striking, it has little to no scent

Growth Habit

• Exhibits both epiphytic and terrestrial habits, developing from a robust rhizomatous base
• Typically forms clumps, which is a common growth form among many Anthurium species

Light Requirements

• Bright, indirect light that mimics the dappled sunlight of its native forest habitat

Watering & Humidity

• Requires consistently moist conditions 
• High humidity

Soil & Potting Mix

• A well-draining, organic-rich medium is best
• A peat-based mix augmented with perlite or orchid bark is recommended to support root health and moisture retention

Temperature & Fertilizer

• Flourishes in temperatures between 65°F and 80°F
• Balanced, diluted fertilizer applied monthly during the active growing season supports sustained growth

Division and Cuttings

• Most common method of propagation is through division of its rhizomes
• Ensure that each segment contains an adequate root system to establish new growth

Seeds

• Less common due to variable germination rates.
• Require specific stratification protocols to improve viability

Typical Issues

• Spider mites and mealybugs
• Overwatering may also lead to issues like root rot

Treatment Recommendations

• Insecticidal soap can help manage pest infestations
• Ensuring proper watering techniques will minimize the risk of fungal diseases

• Noted for its unusual foliage and is sometimes associated with local cultural lore due to its rarity
• Distinct appearance plays a role in the ecological tapestry of its native habitat

• Prized for its rare and aesthetically appealing foliage and inflorescence

Wild Population Status

• Limited; habitat loss due to deforestation in its native range may pose a threat

Market Availability

• Rare in cultivation
• Typically available only through specialized collectors or reputable nurseries that focus on exotic and aroid species
