is a genus of flowering plants in the violet family Violaceae.
 It is the largest genus in the family, containing between 525 and 600 species.
 Most species are found in the temperate Northern Hemisphere; however, some are also found in widely divergent areas such as Hawaii, Australasia, and the Andes.
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.
Plasmopara is a genus of Oomycota.
 "Plasmopara" species are known as plant pathogens, causing downy mildew on carrot, parsley, parsnip, chervil, and impatiens.
Impatiens balfourii is a species of the genus "Impatiens" known by the common names Balfour's touch-me-not, Kashmir balsam, and poor man's orchid.
 It belongs to the family Balsaminaceae.
Viola pubescens, often called downy yellow violet, is a plant species of the genus "Viola".
 It is found in dry mixed and deciduous woodland areas of the United States and Canada; from Minnesota and Ontario to Nova Scotia, South to Virginia.
 It grows 6 to 10 inches tall and is a stemmed viola with stems that have leaves, it blooms from April through May.
Cardamine impatiens, the narrowleaf bittercress or narrow-leaved bitter-cress, is a plant species of the genus "Cardamine" belonging to the family Brassicaceae.
 It is a slender, biennial herb, that produces sterile leaves in the first year, one to several flowering stems during the next.
 Its leaves are pinnate with several pairs of lanceolate, dentate leaflets and a terminal, slightly longer leaflet.
 The short petals surpass the calyx by half of its length.
 The seeds are arranged in one row on each side of the central membrane of the narrow pod and are ejected out in a shower due to the tension formed as the seed pod (silique) dries.
 It grows on walls, open ground in shady places in forests usually disturbed by man.
The garden pansy is a type of large-flowered hybrid plant cultivated as a garden flower.
 It is derived by hybridization from several species in the section "Melanium" ("the pansies") of the genus "Viola", particularly "Viola tricolor", a wildflower of Europe and western Asia known as heartsease.
 Some of these hybrids are referred to as "Viola" × "wittrockiana" Gams ex Nauenb.
 & Buttler.
 For simplicity, the older name "Viola tricolor" var.
 "hortensis" is often used.
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.
Impatiens walleriana (syn.
 "Impatiens sultanii"), also known as busy Lizzie (United Kingdom), balsam, sultana, or simply impatiens, is a species of the genus "Impatiens", native to eastern Africa from Kenya to Mozambique.
 It is a flowering herbaceous perennial plant growing to 15 - tall, with broad lanceolate leaves 3–12 cm long and 2–5 cm broad.
 Leaves are mostly alternate, although they may be opposite near the top of the plant.
 The flowers are profusely borne, 2–5 cm diameter, with five petals and a 1 cm spur.
 The seedpod explodes when ripe in the same manner as other "Impatiens" species, an evolutionary adaptation for seed dispersal.
 The stems are semi-succulent, and all parts of the plant (leaves, stems, flowers, roots) are soft and easily damaged.
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".
