Anthurium papillilaminum × luxurians

Two terrestrial wet-forest species combined in cultivation

This horticultural hybrid joins Anthurium papillilaminum from shaded Panamanian lowland rainforest with Anthurium luxurians from the floor of very wet forest in western Colombia. Both parents are terrestrial and occupy warm, humid organic surface layers beneath forest cover. The breeder and introduction of the listed cross are not publicly documented.

Growing Anthurium indoors

• Light: Give medium to bright filtered light. Strong midday sun can mark the raised leaf surface and overheat the root zone.
• Watering: Keep moisture even, watering when the upper layer of the substrate begins to dry. Drain fully while a new textured leaf is opening.
• Humidity and airflow: Aim for high humidity with gentle airflow over the recessed veins and crown.
• Substrate and repotting: Keep the nursery planting of Anthurium papillilaminum × luxurians stable while light, temperature and watering settle, and follow the well-aerated root zone and emerging foliage for signs of activity; repot when the plant is growing and its drying rate is familiar. Repot later into a snug pot with fine bark, coir, coco chips and pumice or perlite.
• Watering and humidity: Rinse mature textured leaves gently and dry their recessed veins with airflow. Begin with a close-fitting pot and move to a wider container if the stem starts spreading.

Root, stem and leaf problems in Anthurium papillilaminum × luxurians

• Droop and yellowing at the same time: Low pot weight with a dry upper root zone and flexible leaf indicates thirst; rehydrate the mix thoroughly and empty the outer pot. Persistent weight in the pot with damp mix, yellow soft growth or a sour smell indicates root failure; pause the watering cycle and examine the roots and exposed stem.
• Trimming confirmed failed roots: A solid stem at the surface and firm roots can remain; softness is the sign that requires action. Trim only slippery, hollow or blackened roots with a disinfected blade, then use a snug aerated pot and keep the short stem at the surface.
• Inspecting nodes, veins and leaf backs: Thrips damage is easiest to see once a distorted leaf opens; fine stippling in the recesses is more typical of mites. Look closely at recesses, undersides and the central growth point with magnification. Isolate, rinse hardened foliage, treat with a product approved for that pest, make each repeat application on the label schedule and check the same hiding places after treatment.
• Growth pauses after stress: Cool roots may hold a textured leaf at the growth point; wait for root activity before changing the routine again. Return the plant to filtered light with a stable 21–28 °C range; judge improvement from new tissue.
• Reading the edge of a dark lesion: Droplets held between raised veins often leave a fixed outline; use airflow to clear every hollow. Blot visible droplets and let air move through the recesses. An enlarging damp spot needs isolation as soon as its border advances; mark the edge and check if it expands and avoid splashing.

Anthurium papillilaminum × luxurians 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.

Who first published Anthurium papillilaminum and Anthurium luxurians, and what do the names mean?

The genus name Anthurium combines Greek anthos, “flower”, and oura, “tail”, referring to the tail-like spadix. Papillilaminum combines Latin papilla, “small protuberance”, and lamina, “blade”, referring to the finely bumpy leaf surface. The epithet luxurians is Latin for luxuriant or abundant.

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

Thomas Bernard Croat first described Anthurium papillilaminum in 1986 in Monographs in Systematic Botany from the Missouri Botanical Garden, volume 14, page 152.

Thomas Bernard Croat and Richard N. Cirino first described Anthurium luxurians in 2005 in Aroideana, volume 28, page 56.
