formed, thus preventing the grass from being totally destroyed. The grass is therefore capable of
producing new leaves rapidly afterwards.
The leaf of V. nemoralis is 35-60 (maximum 80) cm long and 0.4-0.6 (maximum0.8) cm wide,
and is pale green. The upper surface of the blade flaps with a triangular ridge. The texture is coarse
and a little waxy. The lower surface has the same color as the upper surface but somewhat paler.
When holding the leaf against the sunlight, the septum is not distinctly seen. However, the midrib
that is hardened and ridge-like structure can be clearly seen.
At the same age, the roots of V. nemoralis are shorter than those of V. zizanioides. Generally,
the roots of a one-year-old vetiver plant can be as long as 80-100 cm.
The inflorescence of local V. nemoralis appears in many different colors depending on the
specific ecotype. In Uthai Thani and Nakhon Phanom, the color ranges from beige to reddish purple
(Nanakorn and Chinapan 2000).
