Amorphophallus myosuroides Hett. & A.Galloway

• Genus: Amorphophallus
• Botanical Background: Described by Hett. & A. Galloway in the early 20th century, this species contributes to the broader understanding of the genus Amorphophallus, which has long intrigued botanists for its enormous flowers and unique growth patterns.

• Geographical Range: Native to the tropical forests of Southeast Asia, particularly in regions with high humidity and dense forest coverage, such as parts of Malaysia and Indonesia
• Environment: Thrives in humid, shaded environments with rich, well-drained soils; it grows under the canopy of tropical rainforests where temperatures remain consistently warm and precipitation is frequent

Leaves

• Large, deeply lobed, and glossy
• With a rich green coloration that provides a striking contrast to its flowering structures
• The leaf petiole is stout, supporting the robust foliage

Inflorescence (Spadix & Spathe)

• One of the most distinguishing features of this species
• The spadix, resembling a mouse’s tail, is typically dark brown to purple, while the spathe is a pale greenish hue
• Has a strong, unpleasant odor during bloom to attract pollinators such as flies

Growth Habit

• Terrestrial, growing from a large tuber that it produces annually
• Herbaceous, and it dies back to the ground after blooming, reemerging the following season

Light Requirements

• Prefers bright, indirect light
• Direct sunlight can scorch the leaves, so it should be placed in a shaded area with filtered light

Watering & Humidity

• Requires consistent moisture with regular watering
• Thrives in high humidity levels of 60-80%
• Ensure that the soil is kept moist but not soggy

Soil & Potting Mix

• A well-draining, rich potting mix is ideal
• A mix designed for aroids with organic matter like peat or coconut coir is best

Temperature & Fertilizer

• Prefers a temperature range of 25°C to 30°C (77°F to 86°F)
• Balanced, water-soluble fertilizer monthly during the growing season

Division and Stem Cuttings

• Division of the tuber
• Each division should have at least one growing point to ensure successful regeneration

Seeds

• Less commonly used; may take time to germinate under the right conditions
• Fresh seeds with viable embryos should be sown in a sterile mix

Typical Issues

• Aphids, scale, and mealybugs
• Root rot

Treatment Recommendations

• Organic insecticidal soap or neem oil can be effective for pest control
  
• Ensure the plant is in well-drained soil
• Fungicides may be necessary for severe fungal infections
  

• Known for its striking inflorescence
• Its flower's scent is designed to attract pollinators like carrion beetles and flies
• Prized among Aroid collectors for its unusual appearance and striking bloom
• Also used in conservation collections due to its unique place in the Aroid family

Wild Population Status

• While not officially listed as endangered, its specific habitat requirements and limited geographic range may pose conservation challenges, particularly in areas undergoing deforestation

Market Availability

• Not commonly available in general horticulture
• May be found through specialized Aroid nurseries and collections
