1. Introduction

Habitat and Distribution, Native Continent

Licuala telifera is endemic to northeastern Borneo, specifically restricted to parts of Sabah (Malaysia) and adjacent areas of East Kalimantan (Indonesia). This rare species occurs in lowland to hill forests between 100-800 meters elevation, with a preference for ultramafic soils derived from serpentine geology. It thrives in areas with 2,000-3,500mm annual rainfall and shows remarkable adaptation to these mineral-poor, heavy metal-rich soils that exclude many other plant species. The species is particularly abundant on the lower slopes of ultrabasic hills where it often forms dense stands in the understory. The specific epithet "telifera" means "dart-bearing," referring to the sharp, arrow-like tips of the leaf segments.

Taxonomic Classification and Scientific Classification

Synonyms

• No synonyms (species clearly defined)
• Sometimes confused with L. elegans in cultivation
• Misidentified as L. gracilis in older collections

Common Names

• Dart-tip fan palm (English)
• Arrow licuala (English)
• Sabah fan palm (English)
• Palas anak panah (Malay - "arrow palas")
• 箭尖轴榈 (Chinese)

Expansion in the World

L. telifera has limited presence in cultivation:

• Sabah Agriculture Park (ex-situ conservation)
• Singapore Botanic Gardens (few specimens)
• Private collections in Southeast Asia (rare)
• Montgomery Botanical Center, Florida (single plant)
• Occasionally available from specialist nurseries
• Seeds sporadically offered
• IUCN Red List status: Vulnerable

Its ultramafic soil adaptation makes cultivation challenging outside native habitats.

2. Biology and Physiology

Morphology

Growth Form

L. telifera is a clustering palm of moderate size, forming clumps of 5-20 slender stems. Individual trunks reach 2-4 meters tall and 3-5cm in diameter. The stems are covered with persistent fibrous leaf bases that create a rough texture. New shoots emerge regularly from the base, with colonies slowly expanding over time. The clustering provides resilience against individual stem damage.

Leaves

The leaves are the species' most distinctive feature. Each leaf is circular in outline, 40-70cm in diameter, divided into 10-16 segments. The segments are wedge-shaped with remarkably acute (sharp-pointed) tips that resemble arrow points or darts - unique in the genus. The leaf surface is deep green above with a distinctive metallic sheen, silvery-green below. This metallic quality is thought to be related to heavy metal accumulation from the ultramafic soils. Petioles are 60-120cm long with small marginal teeth.

Special Adaptations

• Sharp-pointed leaf segments (unique feature)
• Metallic leaf sheen
• Heavy metal tolerance
• Clustering on poor soils
• Efficient nutrient cycling

Flower Systems

L. telifera is hermaphroditic with bisexual flowers. Inflorescences emerge from among the leaves, extending beyond them on slender peduncles. The branched panicle is 60-100cm long with cream to pale yellow flowers arranged in small clusters. Individual flowers are 3-4mm across. Flowering occurs throughout the year with peaks during transitions between wet and dry periods. The inflorescence structure is relatively simple compared to other Licuala species.

Life Cycle

L. telifera follows a clustering palm pattern:

• Germination to Seedling (0-2 years): Single stem initially
• Juvenile Phase (2-5 years): First suckers appear
• Clustering Phase (5-10 years): Multiple stems develop
• Adult Phase (10-40+ years): Colony expansion
• Maturity: Individual stems flower at 6-10 years

Colony longevity extends well beyond individual stem life.

Specific Adaptations to Climate Conditions

• Ultramafic Tolerance: Thrives on toxic soils
• Heavy Metal Accumulation: Possible hyperaccumulator
• Nutrient Efficiency: Survives on poor soils
• Clustering Strategy: Colony survival
• Metallic Leaves: Reflects excess radiation
• Sharp Tips: Possible herbivore deterrent

3. Reproduction and Propagation

Seed Reproduction

Seed Morphology and Diversity

L. telifera produces globose fruits, 10-14mm diameter, ripening from green through yellow-orange to bright red. Each fruit contains a single seed surrounded by thin, sweet-sour flesh. Seeds are spherical, 7-9mm diameter, with homogeneous endosperm and a basal embryo. The seed coat is relatively thick. Fresh seed weight is 0.4-0.7 grams. Moderate genetic diversity exists despite soil specialization.
