Boraginaceae, the borage or forget-me-not family, includes about 2,000 species of shrubs, trees and herbs in 146 genera with a worldwide distribution. These plants have alternately arranged leaves, or a combination of alternate and opposite leaves. The leaf blades usually have a narrow shape; many are linear or lance-shaped. They are smooth-edged or toothed, and some have petioles. Most species have bisexual flowers, but some taxa are dioecious. Most pollination is by hymenopterans, such as bees. Most species have inflorescences that have a coiling shape, at least when new, called scorpioid cymes. The flower has a usually five-lobed calyx. The corolla varies in shape from rotate to bell-shaped to tubular, but it generally has five lobes. It can be green, white, yellow, orange, pink, purple, or blue. There are five stamens and one style with one or two stigmas.
