- SPECIES NAME: Chromolaena odorata (Siam weed)
- Formerly Eupatorium odorata
-
- GENERAL COMMENTS: Distribution maps taken from Gautier (1989) and
- McFadyen and Skarratt (1996)
-
- This file is different to previous versions (eg, McFadyen and Skarratt
- 1996). Any analyses using the 1996 parameter values will give slightly
- different results to analyses using this parameter file. All publications
- prior to March 1998 referring to CLIMEX analyses for this species will
- have used the McFadyen and Skarratt 1996 parameter values.
-
- This file was created by Tania Yonow in March 1998.
