Scindapsus coriaceus Engl.

Introduction & Overview

Common and Scientific Names

  • Scientific Name: Scindapsus coriaceus Engl.
  • Common Name: Leathery pothos; Coriaceous pothos

Quick Facts

  • Origin: Native to tropical Southeast Asia, particularly Malaysia
  • Features: Large, heart-shaped, glossy leaves; sought after for both its ornamental value and its resilient growth habits in indoor settings

Taxonomy & Classification

  • Genus: Scindapsus
  • Botanical Background: Described by George Englert in 1910, S. coriaceus is one of many Scindapsus species initially noted for their ornamental and ecological value in tropical regions.

Natural Habitat & Distribution

  • Geographical Range: Native to Southeast Asia, particularly in Malaysia; typically grows in the lowland forests, where it benefits from high humidity and indirect light conditions.
  • Environment: Preferring tropical environments, this species thrives in humid, warm climates with temperatures ranging from 20°C to 30°C. Typically grows in well-drained, organic-rich soils, often in shaded or partially shaded areas under the forest canopy.

Morphological Characteristics

Leaves

  • Large, heart-shaped, and leathery with a deep green coloration
  • Surface is glossy, and the texture is firm to the touch

Inflorescence (Spadix & Spathe)

  • Consists of a spadix surrounded by a spathe
  • Flowers are small and less conspicuous compared to the striking foliage
  • No strong scent associated with the inflorescence, and pollination is typically carried out by insects in its native environment

Growth Habit

  • Grows by attaching to tree trunks or other vertical surfaces
  • Often using aerial roots to support its vertical growth

Cultivation & Care

Light Requirements

  • Thrives in bright, indirect light
  • Direct sunlight may scorch the leaves, while too little light can result in slower growth and less vibrant foliage

Watering & Humidity

  • Water should be kept consistent but not excessive
  • Benefits from higher humidity levels, making it ideal for terrariums or humidity trays in indoor settings

Soil & Potting Mix

  • A well-draining, airy potting mix is preferred, ideally one with organic content like peat or coconut coir
  • Mix should retain moisture without becoming soggy

Temperature & Fertilizer

  • Prefers temperatures between 20°C and 30°C
  • Fertilize with a balanced liquid fertilizer during the growing season (spring and summer), applying once every 4-6 weeks

Propagation Methods

Division

  • Most common propagation method is via cuttings, taken from healthy nodes with aerial roots

Stem Cuttings (if applicable)

  • Cuttings should be rooted in water or directly in soil

Seeds

  • Seeds are not commonly used for propagation in horticultural settings
  • Vegetative propagation methods like cuttings offer faster and more reliable results

Common Pests & Diseases

Typical Issues

  • Spider mites, mealybugs, and aphids
  • Root rot can occur if the plant is overwatered, particularly in poorly drained soil

Treatment Recommendations

  • Insecticidal soap or neem oil can be effective
  • For root rot, reduce watering frequency, and ensure proper drainage
  • Use a fungicide if necessary to address fungal issues

Notable Traits & Uses

  • Often sought for its ornamental value
  • Resilience makes it a popular choice for both collectors and casual growers alike
  • Occasionally noted in local folklore for its robust growth
  • Appreciated for its leathery, glossy leaves and is often used in indoor plant collections

Conservation & Availability

Wild Population Status

  • No major conservation concerns; not listed as endangered

Market Availability

  • Uncommon in general markets but can be found in specialty nurseries or among Aroid collectors
  • Not widely available in mass market outlets
