The Department of Plant Sciences at the University of Colombo is a well-established unit in the Faculty of Science and enjoys a reputation for maintaining high academic standards in the discipline. Formerly known as the Department of Botany, the name was changed recently to ‘Plant Sciences’ in order to reflect more clearly, the changes that the department has effected to the courses that it offers. While still covering areas that come within the traditional boundaries of the subject ‘Botany’, the department has taken a conscious effort to include in its teaching programs, courses that cover the newest developments in the field.

In addition, the department caters the research & development needs of the industrial sector through the science & technology cell of the Faculty of Science, University of Colombo.
