Notes. – WHITE (1993a) described D. fastidiosa from a single flowering specimen from Aoupinié and D. nebulosa from two fruiting specimens from Mt. Panié. In addition to the type specimen of D. fastidiosa, two additional recent flowering specimens from Aoupinié (Munzinger 6632, 7249) show the characteristic inflorescence structure of D. vieillardii, albeit with slightly larger flowers. Moreover, the fruiting specimens of D. nebulosa from Mt. Panié are identical to those of D. vieillardii . Although D. vieillardii occurs nearly exclusively on ultramafic soils, which are not found on either Aoupinié or Mt. Panié, the leaves of material assigned to both D. fastidiosa and D. nebulosa conform exactly to those of D. vieillardii in their complete absence of any visible venation on the lower surface. We therefore consider D. fastidiosa and D. nebulosa to be geographic outliers of D. vieillardii growing on nonultramafic soils.
