Remusatia yunnanensis (H.Li & A.Hay) A.Hay

Introduction & Overview

Common and Scientific Names

  • Scientific Name: Remusatia yunnanensis (H.Li & A.Hay) A.Hay
  • Common Name: Yunnan Remusatia

Quick Facts

  • Origin: Native to Yunnan, China
  • Features: Striking heart-shaped leaves, unusual spathe and spadix structure, distinctive within the Araceae family

Taxonomy & Classification

  • Genus: Remusatia
  • Botanical Background: Described by botanists H.Li and A.Hay, the species has undergone reclassification by A.Hay; its discovery and subsequent study have contributed valuable insights into aroid diversity.

Natural Habitat & Distribution

  • Geographical Range: Indigenous to the mountainous regions of Yunnan, where it is typically found in subtropical forest environments.
  • Environment: Moist, well-drained soils with high humidity and regular rainfall; adapted to moderate climates with stable temperature ranges, mimicking the understory conditions of its natural habitat.

Morphological Characteristics

Leaves

  • Large, heart-shaped leaves with a glossy finish and subtle variegation

  • Coloration ranges from deep green to lighter hues along the edges

Inflorescence (Spadix & Spathe)

  • Greenish spathe surrounding a central spadix

  • May emit a mild scent to attract specific pollinators

  • Characteristic of many aroid species

Growth Habit

  • Terrestrial growth emerging from a robust rhizome

  • Supports vegetative propagation and overall plant form

Cultivation & Care

Light Requirements

  • Best suited for bright, indirect light that simulates the dappled sunlight of a forest understory

Watering & Humidity

  • Regular watering is necessary to maintain consistent soil moisture

  • High ambient humidity further supports its growth

Soil & Potting Mix

  • A rich, well-draining organic mix is ideal

  • Containers must provide sufficient drainage to prevent waterlogging

Temperature & Fertilizer

  • Prospers in moderate temperatures

  • Balanced fertilizer during the growing season encourages healthy development

Propagation Methods

Division

  • Propagation is most effectively achieved through rhizome division

  • Should include healthy roots and shoots to ensure successful growth


Stem Cuttings (if applicable)

  • Not commonly used for this species, but may be explored if aerial roots are present

Seeds

  • Seed propagation is possible under controlled conditions

  • Less commonly employed than division due to longer germination and care requirements

Common Pests & Diseases

Typical Issues

  • Common issues include infestations by spider mites and mealybugs
  • Fungal infections may occur due to excessive moisture

Treatment Recommendations

  • Use organic insecticides or insecticidal soaps for pest control

  • Remove affected foliage and ensure proper air circulation to prevent disease

Notable Traits & Uses

  • Recognized in local botanical studies for its unique morphology

  • Holds cultural significance in regional folklore of Yunnan


  • Distinctive leaf shape and inflorescence appeal to plant collectors

  • Adds ornamental value to specialty aroid collections and tropical-themed gardens


Conservation & Availability

Wild Population Status

  • No significant conservation concerns at present

  • Ongoing habitat monitoring remains important to ensure long-term survival

Market Availability

  • Relatively rare in cultivation but can be sourced from specialist nurseries and botanical gardens

  • Availability may vary by region and often requires sourcing from dedicated collectors
