About

Calamus erectus, also known as viagra palm and locally as tynriew, tara, and zhi li sheng teng, is a flowering shrub in the family Arecaceae. The specific epithet (erectus) refers to the plant's habit of growing straight rather than creeping or climbing like many species of the genus Calamus.

Where it grows

Calamus erectus is native to Northeast India, Nepal, Bhutan, Bangladesh, Myanmar, Thailand, Laos, and the Chinese province of Yunnan. It has been introduced to the United States.

Uses

Although the canes are not useful for making furniture due to the short internodes, the Mising people of the Assam plains sometimes use the canes and leaves to make huts and chicken coops.
