Nastratinaceae
Nastratinaceae is a family of flowering plants that belongs to the order Gentianales. The family is characterized by its distinctive flowers, which are typically small, tubular, and arranged in clusters. The flowers are usually blue or purple, and they are often pollinated by insects. The family is found primarily in the Southern Hemisphere, with the majority of species occurring in South America and Australia. The most well-known genus in the family is Nastranthus, which includes several species of plants that are commonly grown as ornamental plants in gardens and nurseries. The family is named after the genus Nastranthus, which is derived from the Greek words "nasos" meaning "nose" and "anthos" meaning "flower," referring to the shape of the flower tube. The family is monophyletic, meaning that all members of the family are descended from a single common ancestor. The family is relatively small, with only about 20-30 species in total. Despite its small size, Nastratinaceae is an important group of plants for both scientific research and horticultural purposes.
