Alocasia reginula A.Hay

• Genus: Alocasia
• Botanical Background: Described by A. Hay, Alocasia reginula has intrigued botanists with its rare morphology and has been the subject of detailed classification studies within the aroid community.

• Geographical Range: Native to the tropical regions of Southeast Asia, where it is part of the rich biodiversity of the rainforest understory.
• Environment: Humid, shaded conditions with warm temperatures, preferring well-draining, organic-rich soils typical of rainforest floors.

Leaves

• Heart- to arrow-shaped
• Deep, dark green to nearly black coloration
• Velvety texture
• Prominent veining

Inflorescence (Spadix & Spathe)

• Slender spadix surrounded by a contrasting spathe
• Spathe is green or brown

Growth Habit

• Terrestrial specie
• Grows from a rhizomatous root system
• Forms dense clumps

Light Requirements

• Bright, indirect light

Watering & Humidity

• Regular watering to maintain consistent moisture without waterlogging
• High humidity

Soil & Potting Mix

• A well-draining, nutrient-rich potting mix with ample organic matter
• Containers with sufficient drainage

Temperature & Fertilizer

• Temperatures range from 65°F to 80°F
• Balanced liquid fertilizer applied every 4-6 weeks during the growing season

Division and Stem Cuttings

• Rhizome division
• Each divided section should include a viable portion of roots

Seeds

• Rarely used due to low viability and slow germination
• Vegetative propagation is a preferred technique

Typical Issues

• Spider mites and mealybugs
• Root rot

Treatment Recommendations

• Organic treatments such as insecticidal soap or neem oil
• Ensure proper watering practices

• Dramatic dark foliage and compact growth
• Subject of botanical study regarding plant morphology

• Rarity and unusual leaf texture

Wild Population Status

• Detailed data on wild populations is limited
• Habitat loss in tropical regions poses a general threat

Market Availability

• Rare and highly desirable
• Available through specialist collectors rather than mainstream markets
