ABSTRACT
Vetiver grass (Chrysopogon zizanioides L.) is well known for its numerous unique characteristics and environmental friendliness. Currently, vetiver grass is grown and widely applied in many areas around the world. In Vietnam, vetiver has been grown and used extensively since early 1990s to prevent erosion and landslide, and to effectively treat the contaminated environment. Therefore, the demand for this grass is growing. However, there are many species of vetiver that have an ecological distribution worldwide. In terms of external morphology, it is not easy to differentiate between the south Indian vetiver (Chrysopogon zizanioides) and the local indigenous Chrysopogon nemoralis, which is known by the locals as Co De. Presently, in many areas in Quang Nam Province, Co De, which has morphological characteristics similar to Chrysopogon zizanioides, is being exploited and used to prevent erosion and landslide in several projects. However, its performance and effectiveness are not high, thus causing negative impact on the environment as well as psychological doubts about the effectiveness of vetiver. This paper discusses the confusion between the south Indian vetiver Chrysopogon zizanioides and the indigenous Co De - Chrysopogon nemoralis. Following that, some distinguished characteristics of the two grasses will be highlighted in order to eliminate the confusion, thereby improving the efficiency and usage of vetiver grass.
