Nepenthes eymae
AdvancedNepenthes eymae
A highland pitcher plant endemic to Sulawesi, Indonesia. Its upper pitchers are narrow below and flare abruptly above like a wine glass, the feature that separates it from its close relative N. maxima.
About
Nepenthes eymae is a pitcher plant species endemic to Sulawesi, Indonesia, where it grows at 1,000-2,000 m. It was discovered in 1938 by the Dutch botanist P. J. Eyma and described by Shigeo Kurata in 1984 (originally spelled eymai). The same plant was published a few days later as N. infundibuliformis, which is now a synonym. It differs from its close relative N. maxima in the shape of its upper pitchers: the lower half to three-quarters stays narrowly funnel-shaped and then expands abruptly near the mouth into a wine-glass shape. The stem climbs to about 8 m. Lower pitchers are ovate and reach 24 cm tall and 16 cm wide, with a peristome that widens to more than 5 cm at the back. The lid margin is often finely crenellated. Upper pitchers are smaller, about 15 cm tall and 8 cm wide. Some authors doubt that it deserves species rank apart from N. maxima. Most plants cultivated as N. eymae reportedly do not produce the typical wine-glass upper pitchers, so do not expect the shape from the name alone. It is listed as Least Concern by the IUCN. In Japan, seed-grown plants from specialist nurseries appear at online auctions.

Growing Tips
Temperature & Overwintering
A highland species that needs cool nights to thrive long term; warm Japanese summer nights are the main challenge.
Light & Placement
Likes bright light, but harsh midsummer sun can scorch it. Keep it in bright part shade where humidity can be kept up.
Watering
Use rain water or water low in dissolved minerals and water before the mix dries out. Do not leave the pot standing in water.
Soil & Repotting
Plant in a free-draining, airy mix; pure sphagnum or orchid mix with sphagnum or perlite are common choices.
Fertilizer
If using chemical fertilizer, use it at very low strength; an occasional insect dropped into a pitcher is enough.
Pests & Cautions
Most cultivated plants reportedly do not form the typical wine-glass upper pitchers; if the shape matters to you, choose a plant sold with photos of its upper pitchers.
