Nemesia(redirected from nemesias)
Also found in: Dictionary.
a genus of herbaceous, usually annual plants of the family Scrophulariaceae; less frequently, the plants are subshrubs. The leaves are opposite and entire. The flowers are in racemose or corymbiform inflorescences; rarely are they solitary. The corolla has a bilabiate blade and a short tubule, which is widened into a sac or elongated into a spur. There are four stamens. The fruit is a capsule. There are more than 50 species, found in southern Africa. Some annual species, such as Nemesia strumosa and N. versicolor, are ornamentals. Hybrid forms and varieties with variously colored large flowers are most often cultivated. They are used as borders, in rock gardens, and for cuttings.
