Heteroaridarum nicolsonii (Bogner) S.Y.Wong & P.C.Boyce

• Genus: Heteroaridarum
• Botanical Background: Described by Bogner, its reclassification highlights the contributions of several prominent botanists in aroid systematics

• Geographical Range: Native to tropical regions of Southeast Asia, where diverse rainforests create ideal growing condition
• Environment: Thrives in humid, shaded forest understories with well-draining, organic-rich soils and consistent warm temperatures

Leaves

• Broad, textured leaves
• Subtle variegation that provide a lush backdrop for its inflorescence

Inflorescence (Spadix & Spathe)

• Moderately sized spathe and spadix, typically displaying muted green tones
• Spathe may emit a slight scent to attract specialized pollinators

Growth Habit

• Terrestrial species that grows from a rhizome
• Forming clumps over time

Light Requirements

• Bright, indirect light to mimic the dappled sunlight of a forest understory

Watering & Humidity

• Requires consistent moisture
• High humidity levels
• Ensure proper drainage to avoid waterlogging

Soil & Potting Mix

• A rich, well-draining potting mix supplemented with organic matter

Temperature & Fertilizer

• Thrives in warm, stable temperatures
• Balanced fertilizer during the growing season supports its development

Division

• Most common propagation technique is through division of the rhizome, which reliably produces new plants

Seeds

• Less common due to variable germination rates and may require controlled conditions

Typical Issues

• Spider mites and mealybugs
• Root rot

Treatment Recommendations

• Organic insecticidal soaps
• Careful watering and drainage help prevent fungal infections

• Celebrated for its unusual inflorescence structure and ecological significance
• Collectors prize this aroid for its rarity and unique aesthetic

• A standout specimen in tropical plant collections

Wild Population Status

• Due to habitat loss and ecological pressures, conservation efforts are important for maintaining wild populations

Market Availability

• Considered rare
• Typically available only through specialized collectors or niche botanical suppliers
