Anthurium clarinervium

Botanical identity and natural origin of Anthurium clarinervium

Anthurium clarinervium is native to Chiapas in southern Mexico, where it grows as a subshrub in the seasonally dry tropical biome.

Its known native range is limited to this part of Mexico.

Caring for Anthurium clarinervium

• Keep the stem above the potting mix: Choose a container that closely fits the roots and set the plant so the growing point remains clear of the surface.
• Let the upper mix dry before watering again: Soak the root ball thoroughly, drain the pot and wait until the top layer has dried. The deeper mix should not stay saturated.
• Give bright filtered light: Gentle early or late sun can be introduced gradually. Strong midday light can bleach the matte surface or leave fixed tan patches.
• Keep the newest growth clear and dry: Blot water that collects around the central leaf and provide gentle airflow. Feed lightly while fresh roots and foliage are developing.

Common problems with Anthurium clarinervium

• Firm leaves become flexible and the pot feels light: The root ball has dried too far. Water it completely, let it drain and shorten the next interval slightly.
• Several leaves yellow while the pot remains damp: Delay watering, let excess moisture drain and move the plant away from cold glass or draughts. If yellowing spreads, the central stem loosens or the mix smells stale, take the plant out of its container and check the roots directly. Leave all firm roots undisturbed. Remove soft, hollow or foul-smelling sections with clean tools, replace degraded waterlogged substrate with fresh airy mix, and extend the next watering interval.
• A tan patch appears on the window-facing side: Direct sun or heat through glass has scorched the leaf. Shift the plant farther from the glass or diffuse the direct sun; the existing mark will remain.
• Brown tips return on otherwise healthy leaves: Long dry gaps and mineral residue can produce the same symptom. If the pot has become very light between waterings, soak the root ball thoroughly and shorten the next interval slightly. Flush the mix once and use lower-mineral water only when a pale crust on the substrate or pot rim, or repeated damage after feeding, points to residue. The brown leaf tips guide covers the main checks in more detail.

Anthurium clarinervium 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.

Where does the name Anthurium clarinervium come from?

The genus name Anthurium combines Greek anthos, “flower”, and oura, “tail”, referring to the tail-like spadix. Clarinervium combines Latin clarus, “clear” or “bright”, and nervus, “vein”: “bright-veined”.

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

Eizi Matuda first described Anthurium clarinervium in 1952 in Anales del Instituto de Biología de la Universidad Nacional de México, volume 22, page 375.
