Abstract
A new species of Disa, the largest genus of terrestrial orchids in southern Africa, is described from the Western Cape. Disa virginalis, sp. nov., was previously included in D. maculata, but is white rather than blue, with sh orter and broader lateral sepals, and a less developed spur. In addition, t he galea is narrowed in front. Similarities to D. schizodioides are also di scussed; these indicate that the current sectional classification of subgen us Disa may not be correct.
