Introduction & Overview

Common and Scientific Names

  • Scientific Name: Taccarum caudatum Rusby
  • Common Name: Without widely used common names

Quick Facts

  • Origin: Native to humid tropical forests in South America
  • Features: Distinctive tail-like spadix and broad, lustrous leaves 

Taxonomy & Classification

  • Genus: Taccarum
  • Botanical Background: Described by botanist Rusby in the early 20th century, this species has contributed to our understanding of aroid diversity and the evolutionary nuances of tropical flora.

Natural Habitat & Distribution

  • Geographical Range: Indigenous to select regions in South America, with populations likely found in tropical and subtropical zones that include parts of the Andean regions
  • Environment: Thrives in shaded forest understories with high humidity, rich organic soils, and a consistent, moist climate, typical of tropical rainforests.

Morphological Characteristics

Leaves

  • Large, glossy leaves
  • Elliptical or heart-shaped
  • Vibrant green coloration
  • Smooth texture add to the species’ ornamental appeal

Inflorescence (Spadix & Spathe)

  • Central spadix accompanied by a broad spathe, often exhibiting a long, tail-like extension
  • Unique structure may emit a subtle scent to aid in attracting specialized pollinators

Growth Habit

  • Grows from rhizomes that form dense clumps, allowing for a spreading yet contained growth pattern

Cultivation & Care

Light Requirements

  • Bright, indirect light
  • Direct sunlight should be avoided to prevent leaf burn while ensuring adequate light for growth

Watering & Humidity

  • Regular watering is essential to maintain consistently moist, but not waterlogged, soil
  • High ambient humidity is beneficial for its overall health

Soil & Potting Mix

  • Well-draining, organic-rich potting mix 
  • Containers with ample drainage holes 

Temperature & Fertilizer

  • Ideal growing temperatures range between 65°F and 80°F
  • Balanced, water-soluble fertilizer applied monthly during the growing season 

Propagation Methods

Division

  • Most effectively achieved through division of the plant’s rhizomes
  • Ensures that new plants retain the characteristics of the parent

Seeds

  • Less common due to variable germination rates and a longer period required for establishment

Common Pests & Diseases

Typical Issues

  • Spider mites and mealybugs
  • Fungal problems like root rot if overwatering occurs

Treatment Recommendations

  • Regular monitoring is key to early detection
  • Mild insecticidal soap or neem oil can manage pest infestations
  • Improving air circulation
  • Adjusting watering practices are effective measures

Notable Traits & Uses

  • Long, tail-like extension of its inflorescence is a striking feature that has spurred both horticultural interest and local folklore
  • Highly prized among tropical plant enthusiasts and collectors, often serving as a conversation piece in specialized gardens

Conservation & Availability

Wild Population Status

  • Not extensively documented, suggesting that the species may be rare in its natural habitat
  • Conservation initiatives remain limited due to its specialized niche

Market Availability

  • Not widely available in mainstream horticultural markets
