Description and Ethnobotany
| Growth Form | Tall grass that grows up to 1-1.5 m tall. |
|---|---|
| Foliage | Smooth or hairy leaves are linear to lanceolate (typically 0.2-0.3 m tall, but sometimes up to 0.5 m tall). Leaves emit a strong aroma when crushed. |
| Flowers | Green to purple, tiny flowers known as spikelets are arranged in a panicle composed of 20 racemes (spike-like inflorescences with stalked flowers). The inflorescence emits a strong aroma when crushed. |
| Others - Plant Morphology | Conservation Status: Earlier literature recorded the species as native to Singapore, vulnerable / rare. (Ali Ibrahim et. al., 1995, Ali Ibrahim & SC Chin, AI 227). However, due to its habitat, it is now thought to be possibly exotic and of uncertain origin. (Hugh Tan et. al., 2009) |
| Habitat | Open grassy areas, inland or coastal, around Old World tropics, fairly uncommon in Singapore. |
| Ethnobotanical Uses | Others: Used as forage grass in some parts of world. |
