Anthurium perangustum Croat

• Genus: Anthurium
• Botanical Background: Described by renowned aroid specialist Thomas Croat in 2022; Croat’s extensive taxonomic work, particularly in regions such as Panama and northern South America, has significantly advanced our understanding of these plants.

• Geographical Range: Native to humid tropical regions in Central or northern South America.
• Environment: Thrives in the shaded understories of moist forests, favoring well-draining, organically rich soils; presumed to require high humidity and warm, stable tropical temperatures.

Leaves

• Narrow or constrained leaf form
• Elongated, narrow, and possibly glossy leaves

Inflorescence (Spadix & Spathe)

• Spadix surrounded by a modified bract (spathe)
• Inflorescence will play a role in attracting specialized pollinators

Growth Habit

• Terrestrial or occasionally epiphytic herb, with a creeping rhizome system

Light Requirements

• Bright, indirect light similar to the dappled shade of a tropical forest

Watering & Humidity

• Moist, yet well-draining soil
• Regular watering with high ambient humidity is essential

Soil & Potting Mix

• An ideal mix would include peat or coconut fiber combined with perlite or orchid bark
• Slightly acidic to neutral pH is usually optimal

Temperature & Fertilizer

• Generally between 18–28 °C
• Balanced, slow-release fertilizer applied monthly during the growing season

Division

• Propagation is most commonly achieved through division of the clump

Stem Cuttings (if applicable)

• Stem or node cuttings taken during the growing season can also successfully produce new plants

Seeds

• Usually propagated vegetatively due to seed viability challenges and the specific requirements for germination

Typical Issues

• Spider mites and mealybugs
• Susceptibility to fungal root rot if overwatered

Treatment Recommendations

• Ensuring proper air circulation and avoiding excessive moisture
• Organic insecticidal soap or neem oil
• Cultural controls and careful watering practices

• Represents the expanding frontier of tropical botany
• Uniquely narrow foliage makes it a subject of interest

• Prize this species for its distinct leaf architecture and rarity
• Unique appearance makes it an attractive specimen for specialized tropical or aroid collections

Wild Population Status

• Conservation status has not been comprehensively evaluated
