Anthurium chilmabajense – Rare Strap-Leaf Aroid with Distinct Upright Form


Anthurium chilmabajense is a newly identified and yet-to-be-formally-published species from Guatemala, belonging to the section *Leptanthurium*. This upright-growing aroid stands out with its narrow, elongated, leathery leaves and robust, self-heading growth habit. Each leaf has a slightly matte finish with subtle texture, held aloft on sturdy petioles that emerge from a compact central base. Unlike sprawling climbers, this species forms a tidy vertical shape with consistent symmetry — ideal for growers seeking architectural form and rarity in one package. Still extremely scarce in cultivation, it’s a collector's species with strong botanical appeal.


Leaf Shape and Structure of Anthurium chilmabajense



 
Leaf shape: Narrow, strap-shaped (linear-lanceolate), straight with pointed tips
 
Colour: Deep green with a soft satin sheen and lightly visible venation
 
Growth habit: Self-heading, upright rosette without vining tendencies
 
Indoor size: Typically reaches 40–60 cm in height and 30–50 cm in width
 
Texture: Thick, leathery foliage with subtle midrib and smooth margins


Habitat and Origin of Anthurium chilmabajense


Anthurium chilmabajense originates from humid montane forests in Alta Verapaz, Guatemala, where it grows terrestrially or as a lithophyte in shaded, mossy conditions. The native environment is cool and moist, with consistent cloud cover, high humidity, and moderate rainfall. The species was discovered by botanist Thomas Croat and is pending formal publication. In cultivation, it retains its compact, structured form and responds well to bright, filtered indoor light, steady moisture, and gentle airflow — closely mimicking its native high-elevation forest floor environment.
⚠ Caution: Like most Anthurium species, it is toxic if ingested. Keep out of reach of pets and children.


How to Care for Anthurium chilmabajense



 
Light: Bright, indirect light is ideal; avoid direct sun to prevent leaf burn
 
Watering: Keep substrate evenly moist; allow top layer to dry slightly between waterings
 
Humidity: Prefers 60–80%; thrives in cabinets, greenhouses, or humid rooms
 
Temperature: Best between 18–26 °C; dislikes sudden cold or dry heat
 
Soil: Loose, well-aerated mix with bark, perlite, coco husk, and compost
 
Repotting: Every 1–2 years or when roots begin to crowd the pot
 
Fertilising: Monthly feeding with diluted complete fertiliser during active growth
 
Propagation: Through basal division or offsets when mature
 
Hydroponics: Possible in semi-hydroponics with high humidity and balanced nutrients
 
Pruning: Remove old or damaged leaves close to the base to maintain shape


Common Problems with Anthurium chilmabajense



 
Browning leaf tips: Caused by low humidity or fertiliser salt build-up
 
Yellowing leaves: Usually overwatering or poor drainage — check substrate condition
 
Pest issues (thrips, spider mites): Rare but possible — inspect regularly and act early
 
Leaf curling: From underwatering or exposure to dry air — adjust humidity and watering
 
Root rot: Avoid soggy soil and ensure airy potting medium


Extra Tips for Growing Anthurium chilmabajense


Anthurium chilmabajense benefits from steady, gentle care and thrives in microclimates that mimic its high-altitude origin. Use shallow, breathable pots and rotate occasionally for balanced growth. The species does not need support and will maintain its vertical structure with minimal pruning. Consistency in humidity, moisture, and light is key to unlocking its long-term resilience and beauty.


Etymology and Botanical History of Anthurium chilmabajense


Anthurium is derived from the Greek “anthos” (flower) and “oura” (tail), referring to the spadix. The specific name chilmabajense refers to the region of Chilmabaj in Alta Verapaz, Guatemala, where the species was first collected. It was identified and described by botanist Thomas B. Croat, though the name is not yet officially published (sp. nov. ined.).
