Anthurium chilmabajense

Cultivated material carrying an unpublished name

Plants circulated as Anthurium chilmabajense have been associated in horticulture with north-western Ecuador. The name remains unpublished; a formal type, traceable wild collection and measured habitat profile have yet to be established for the cultivated material. That leaves a useful but limited provenance: an Ecuadorian association and a cultivated plant with long ribbed leaves. Range, elevation and rooting position stay open, so direct observation of roots and new growth is the sound basis for care.

Growing Anthurium indoors

• Humidity and airflow: Begin with moderate to high humidity and steady gentle air exchange. Clean leaf expansion and a crown that dries promptly indicate a suitable balance; increase humidity only if new growth shows persistent dry-air stress.
• Light: Give bright, diffused light and keep the plant away from hot sun or heat trapped behind glass.
• Watering: Maintain even moisture in an airy root zone. Water as soon as the surface begins to dry, using rainwater or other low-mineral water when available.
• Substrate and repotting: Leave Anthurium chilmabajense in its nursery pot until fresh root tips or a cleanly opening leaf show that it has resumed growth. Repot into a ventilated pot with fine bark, coir or chopped sphagnum and pumice, preserving the existing planting depth.
• Feeding: Use a complete fertiliser at very low concentration while growth is visible. Flush with plain water occasionally and avoid strong or salt-heavy feeds.

When Anthurium chilmabajense needs attention

• Drooping with yellow foliage: Reduced pot weight with dry fine mix and flexible narrow leaves indicates thirst; water evenly with low-mineral water and drain. Soft yellow growth above a heavy damp root zone points to lost aeration. Warm stagnant air can also cause wilting while moisture remains adequate.
• Soft roots and the remaining firm tissue: Healthy roots feel firm in a fine airy mix that stays lightly moist. Remove hollow or slippery tissue with a disinfected blade, use a ventilated snug pot and restore cooler moving air during recovery.
• Thrips, mites and hidden feeding sites: Thrips scar the deeply veined new leaves and mites create fine stippling in the recessed surface. Review veins, undersides and the newest leaf with magnification. Isolate, clean hardened foliage, use a product labelled for the pest and follow its repeat interval.
• Browning along the leaf edge: Brown tips can appear after dry roots or salts, while broad edge damage during warm periods can also reflect stagnant air or rapidly changing conditions. Check the root zone, run low-mineral water through the pot and restore a stable 18–27 °C range with gentle air exchange.
• A dry bruise or enlarging dark spot: A fixed dry mark can appear after contact or sun. Wet or yellow-edged lesions that enlarge need isolation, dry foliage; increase air exchange around the affected plant.

Anthurium chilmabajense is toxic to people and pets

• Keep this plant away from children, cats and dogs.
• Its leaves and stems contain insoluble calcium oxalate crystals, which can irritate the mouth, throat, skin and eyes.
• Chewing may cause burning pain, drooling, swelling, vomiting or difficulty swallowing. Contact a veterinarian or medical professional after exposure, especially if swelling or breathing problems occur.

What does the name Anthurium mean?

The genus name Anthurium combines Greek anthos, “flower”, and oura, “tail”, referring to the tail-like spadix.

Heinrich Wilhelm Schott established the genus Anthurium in 1829 in Wiener Zeitschrift für Kunst, Literatur, Theater und Mode, volume 3, page 828.
