Cercospora apii is a fungal plant pathogen, who causes leaf spot on celery, and found on other plants, including "Impatiens".
 Since the genus Cercospora is one of the largest and most heterogeneous genera of hyphomycetes, numerous species described from diverse hosts and locations are morphologically indistinguishable from C. apii and subsequently are referred to as C. apii sensu lato.
Hydrocera is a genus of flowering plants in the family Balsaminaceae (balsams).
 It contains a single species, Hydrocera triflora, from Southeast Asia.
 It is the only other genus in the family Balsaminaceae besides "Impatiens".
Corylopsis is a genus of nearly 30 species of shrubs in the witch hazel family, Hamamelidaceae, native to eastern Asia with the majority of species endemic in China but with some also in Japan, Korea, and the Himalayas.
 This genus is also known from the extinct species "Corylopsis reedae" described from Eocene leaf fossils found in Washington State, USA.
Impatiens is a genus of about 850 to 1,000 species of flowering plants, widely distributed throughout the Northern Hemisphere and the tropics.
 Together with the genus "Hydrocera", "Impatiens" make up the family Balsaminaceae.
