Introduction & Overview

Common and Scientific Names

  • Scientific Name: Schottarum josefii (A.Hay) P.C.Boyce, S.Y.Wong & S.L.Low
  • Common Name: Josef’s Schottarum

Quick Facts

  • Origin: Native to Southeast Asian tropical forests
  • Features: Distinctive, glossy leaves and an unusual inflorescence

Taxonomy & Classification

  • Genus: Schottarum
  • Botanical Background: Described by A. Hay and later reclassified by Boyce, Wong, and Low, this species has attracted scientific attention for its unique morphological traits and genetic distinctiveness

Natural Habitat & Distribution

  • Geographical Range: Native to the lowland tropical forests of Southeast Asia, likely including regions such as Borneo
  • Environment: Thrives in warm, humid conditions with well-draining, organic-rich soils and receives dappled light under the forest canopy

Morphological Characteristics

Leaves

  • Large, broad, glossy leaves
  • Subtle venation 
  • Predominantly dark green coloration 
  • Lighter patterns

Inflorescence (Spadix & Spathe)

  • Compact spadix enclosed by a cream to white spathe with delicate markings
  • No notable scent
  • Pollination is believed to involve small insects drawn by its visual cues

Growth Habit

  • Grows terrestrially with a robust rhizome
  • Forming clumps that lend themselves well to division

Cultivation & Care

Light Requirements

  • Bright, indirect light to mimic the understory conditions of its native habitat

Watering & Humidity

  • Requires regular watering to maintain consistent moisture while avoiding waterlogging
  • High humidity is beneficial

Soil & Potting Mix

  • A loose, organic-rich potting mix with excellent drainage in a container that allows ample room for root expansion

Temperature & Fertilizer

  • Ideal temperatures range from 65 to 80°F
  • Balanced liquid fertilizer during the growing season supports healthy development

Propagation Methods

Division and Cuttings

  • Most common propagation method is via division of the rhizomes during repotting
  • Node cuttings can also be successful with careful handling

Seeds

  • Slow germination rate and require sterile conditions along with patient care

Common Pests & Diseases

Typical Issues

  • Spider mites and mealybugs
  • Occasional root rot often caused by overwatering

Treatment Recommendations

  • Insecticidal soap or neem oil
  • Adjust watering practices to prevent fungal issues

Notable Traits & Uses

  • Intrigued both botanists and collectors due to its rare form and intricately structured inflorescence
  • Unique leaf patterns and striking floral display make it a coveted addition to specialized tropical plant collections

Conservation & Availability

Wild Population Status

  • Habitat loss from deforestation poses potential risks to its wild populations, highlighting the need for ongoing conservation efforts

Market Availability

  • Considered rare and is typically found through specialized collectors and botanical institutions rather than mainstream nurseries
