While vinca can normally withstand blazing heat, there are times that the flower looks like it is under drought stress. Based on the morphological, physiological and molecular features, this new species is named as Phytophthora mississippiae sp. A reduced efficacy of metalaxyl against Phytophthora nicotianae in tobacco was observed in Cuba in 1983/84. P. nicotianae and P. parasitica are considered conspecific but the epithet nicotianae must be retained over parasitica which it antedates, despite the ambiguity and incompleteness of the original description of P. nicotianae.
