Botany and evolution of Delphinium

Delphiniums are herbaceous perennials belonging to the genus Delphinium of the Ranunculaceae family. The genus includes over 300 species, with a wide variety of flower colors, shapes, and sizes. The name “Delphinium” is derived from the Greek word “delphis,” which means dolphin, due to the shape of the nectary, which is said to resemble a dolphin.

Delphiniums are believed to have originated in Asia and Europe, and their distribution has expanded through human cultivation. The genus includes both annual and perennial species, and they are known for their tall, showy spikes of densely packed flowers.

The flower structure of Delphiniums is unique, with five petal-like sepals that form the characteristic “spur” at the back of the flower.

The leaves of Delphiniums are palmately lobed or divided, and the tall, erect stems have alternate leaves. The fruit of the Delphinium flower is a follicle that contains numerous small, black, shiny seeds.

In terms of evolution, the genus Delphinium is believed to have originated in the Late Eocene to Early Oligocene period, approximately 33 to 40 million years ago. The earliest known fossils of the genus have been found in North America, and it is believed that the genus diversified and spread to other parts of the world through multiple migration events.
