Habitat and Ecology
Sarawak is a tropical country with an equatorial climate that experiences two monsoonal changes. "M. juwiniana" grows in the area of the Northeast Monsoon which occurs between November and February. Daily temperatures range from 23°C and 32°C. The humidity is consistently high exceeding 68%, and annual rainfall varies between 330 cm and 460 cm. The soil is characteristic of the region. It is formed quickly by decomposing plant matter and weathering of rocks, but it is quickly depleted due to the heavy rainfall and absorption by the luxuriant plants. Soils tend to be well leached with high acidity and low fertility. Soil type is in the group of lithosols, which are derived of sandstones and shales.

Morphology
The plant is suckering freely with a slender pseudostem 1.7-3 m high and 710 cm in diameter at 30 cm above the ground. It is a shiny medium green to greenish yellow, or sometimes with pink-purple sparse blotching.
