Anoectochilus lylei

Origin, habitat and conservation of Anoectochilus lylei

Anoectochilus lylei is native to Yunnan, Myanmar and northern Thailand. It grows in shaded seasonal evergreen and hill-forest habitats, including mossy humid sites at roughly 750–1,400 m on granite and sandstone in Thailand.

A 2025 assessment placed the species in the Endangered category using IUCN criteria.

Growing conditions for Anoectochilus lylei

• Humidity and enclosure use: Keep the air humid around the plant. In a terrarium or cabinet, provide enough airflow for the leaves to dry promptly.
• Light: Choose low to moderate filtered light. A gentle grow light or an east-facing window with filtered light can work well.
• Watering: Keep the fine roots evenly moist and rewater once the top feels lightly damp. Allow the pot to drain completely after each watering.
• Temperature: A warm room with fairly stable temperatures supports healthy roots and fresh foliage.
• Potting mix: Use an organic potting mix that stays moist and drains well. Small bark pieces help keep the mix loose.
• Feeding: Feed lightly while the plant is actively growing. Use plain water periodically to reduce salt accumulation.
• Slower growth: If growth slows in cooler or dimmer conditions, keep checking the mix and reduce feeding until new growth starts again.
• Repotting and propagation: Repot when the mix breaks down or becomes compact around the stem. A rooted stem section with new growth can be planted separately.

Troubleshooting Anoectochilus lylei

• Leaves curl and lose their firm feel: Start by checking whether the fine roots have become too dry or the pot is drying unusually fast in warm, dry air. Water thoroughly, then water a little sooner if the pot is drying too quickly.
• Brown marks appear after foliage remains wet: Bacterial and fungal leaf spots can develop on persistently damp leaves. Remove severely affected tissue, keep water off the leaves and provide gentle airflow.
• Fine stippling, pale scratches, webbing or waxy pests appear: Examine tender growth and leaf undersides for mites, thrips, scale or mealybugs. Separate an infested plant. After confirming the pest, use an indoor-plant product that lists it on the label. Follow the label for dose and repeat treatment.
• A dark mark appears at the base while the plant wilts: Fungal disease can affect the stem or roots. Remove dead roots and diseased tissue and make sure the mix is loose and drains freely. Only treat after identifying the fungal disease. Use a fungicide whose label lists it for indoor ornamental plants. Follow the label for dose and repeat treatment.
• The creeping stem becomes soft: Waterlogged mix can deprive the roots of air, and bacterial soft rot can cause rapid stem collapse. Trim off all soft tissue with a clean tool, stopping at firm healthy growth. Discard the rotten tissue and place the healthy section on fresh potting mix with good drainage so it can root again.

Keep Anoectochilus lylei away from children and pets

• Keep this plant away from children, cats and dogs.
• Its effects after chewing or swallowing are unclear, and plant material can still cause an upset stomach.
• Contact a veterinarian or medical professional if symptoms develop or do not settle.

How the name Anoectochilus lylei came about

Anoectochilus combines Greek anoiktos, meaning open, with cheilos, meaning lip, referring to the spreading form of the flower’s labellum. The epithet lylei honours a collector named Lyle.

Carl Ludwig Blume established the genus Anoectochilus in 1825 in Bijdragen tot de Flora van Nederlandsch Indië, page 411.

Dorothy G. Downie first described Anoectochilus lylei in 1925 in Bulletin of Miscellaneous Information, Kew, volume 1925, page 411; Robert Allen Rolfe had proposed the name.
