Wild Coffee (Jiujiemu) has a very strong shade tolerance, and prefers a warm and wet environment without strong sunlight. It is a wild plant commonly seen in Taiwan's broadleaf forests. It is also known as "Mountain's Big Knife" (Shandadao) or "Green Dragon Throwing Up Fog" (Qinglongtuwu).

The branches and twigs have many nodes (jie), which is the origin of the Chinese name. The blossoms are tiny and white, may have light-green on the top, and flower in May and June. The roots and leaves have medicinal quality, e.g. detoxifying and dehumidifying, and therefore are used to cure the common cold, sour throat, bruises, etc.

The fruit is very round, ripens from November through December, is red or reddish orange, and has edges when dried.
