Are Tabernaemontana and Caltha both genus of flowering plants ?
Caltha Caltha is a genus of rhizomatous perennial flowering plants in the family Ranunculaceae ("buttercup family"), to which ten species have been assigned. They occur in moist environments in temperate and cold regions of both the Northern and Southern Hemispheres. Their leaves are generally heart-shaped or kidney-shaped, or are characteristically diplophyllous (the auricles of the leaf blades form distinctly inflexed appendages). Flowers are star shaped and mostly yellow to white. True petals and nectaries are missing but the five or more sepals are distinctly colored. As usual in the buttercup family there is a circle of stamens around (two to twenty-five) free carpels.
Clitandra Clitandra is a genus of flowering plants in the family Apocynaceae, first described as a genus in 1849. A total of 46 names have been coined since that time for species, subspecies, and varieties within the genus, but most of them have been transferred to other genera. The genus is currently regarded as containing only one species, Clitandra cymulosa, native to tropical Africa (from Sierra Leone to Tanzania, south to Angola).
