Hyophorbe lagenicaulis

Natural range and habitat of Hyophorbe lagenicaulis

Hyophorbe lagenicaulis is endemic to Mauritius in the Mascarene Islands. It grows naturally in warm tropical habitat and is Critically Endangered in the wild.

Its native habitat includes well-drained sandy ground in upland forest and coastal savanna.

How to care for Hyophorbe lagenicaulis

• Light: Give the palm the brightest indoor position available and introduce direct sun gradually.
• Temperature and humidity: Warm, stable conditions around 20–30 °C suit it; 15 °C is the lower limit for prolonged exposure. A 50–60% humidity range suits it. Allow gentle circulation around new growth.
• Water: Water deeply when the upper part of the potting mix has begun to dry, then let excess water drain completely.
• Potting mix: Use a loose palm mix that holds some moisture and drains freely. Choose a stable pot as the trunk and crown gain weight.
• Feeding: Use a complete palm fertiliser with potassium, magnesium and micronutrients while new fronds are growing.
• Repotting and pruning: Increase pot size when roots densely fill the container and handle the root system gently. Remove a frond once it has turned fully brown.

Problems with Hyophorbe lagenicaulis

• Older fronds develop orange-yellow spotting, pale patches or scorched-looking edges: A potassium shortage is one possible cause when older fronds are affected first. Use a complete palm fertiliser containing potassium and magnesium and check how the next fronds develop.
• Leaflet tips turn dry and brown: The plant has dried too far between waterings or salts have built up in the mix. Water more consistently and flush the pot thoroughly with fresh water.
• Fronds develop pale dry patches after a move into stronger sun: The leaves have scorched. Move the palm back from the strongest sun, then reintroduce direct light gradually.
• Brown scale bumps, pale speckles or fine webbing appear: Check for scale insects or spider mites. Isolate the palm and repeat a treatment labelled for palms as directed.
• The newest unopened frond, or spear, loosens and the crown becomes soft: Rot may be moving through the crown or roots. Inspect the root system and crown, remove soft tissue back to firm healthy tissue with clean tools, discard the rotten tissue, and improve drainage and airflow.

Keep Hyophorbe lagenicaulis 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.

What does Hyophorbe lagenicaulis mean, and who first published it?

Hyophorbe combines Greek hys, meaning pig, with phorbe, meaning fodder, referring to a reported historical use of fruits in the genus as pig feed. Lagenicaulis combines Latin lagena, flask or bottle, with caulis, stem, describing the swollen trunk.

Joseph Gaertner established the genus Hyophorbe in 1791 in De Fructibus et Seminibus Plantarum, volume 2, page 186.

Liberty Hyde Bailey first described it as Mascarena lagenicaulis in 1942 in Gentes Herbarum, volume 6, page 74. Harold Emery Moore later placed it in Hyophorbe as Hyophorbe lagenicaulis in 1976 in Principes, volume 20, page 119.
