The Apiaceae Family: A Botanical Overview

The Apiaceae family, sometimes called Umbelliferae, is a large group of flowering plants that includes more than 3,800 species spread across roughly 446 genera (1). It’s often referred to as the carrot or parsley family because of its famous members. This family is known for its aromatic herbs and vegetables, many of which play important roles in cooking and medicine.

Characteristics of Apiaceae Plants

One of the most recognizable features of Apiaceae plants is their flower structure. They produce small flowers arranged in umbels clusters that spread out like the ribs of an umbrella. This trait is so defining that the family’s old name, Umbelliferae, literally means “umbrella bearing.” Parsley and carrots both display this pattern clearly.

In addition to their flowers, Apiaceae plants usually have:

• Hollow, furrowed stems
• Compound leaves that are often finely divided or feathery
• Flowers with five sepals, five petals, and five stamens

These shared traits make it easier to identify members of this family, even if their edible parts differ widely.

Aromatic Oils and Culinary Uses

Many Apiaceae species contain essential oils stored in secretory glands, which give them their distinctive aromas and flavors (2). Parsley’s fresh, slightly peppery taste and carrot’s sweet earthiness both come from these aromatic compounds. This chemical similarity explains why many plants in this family are used as herbs and spices, as well as vegetables.

Parsley’s Botanical Traits and Its Place in Apiaceae

Parsley, scientifically known as Petroselinum crispum, fits neatly into the Apiaceae family based on its morphology and genetics. Its flat or curly leaves, hollow stems, and umbel flowers all mirror the family’s defining characteristics.

Leaf and Stem Structure

Parsley leaves are finely divided and feathery, resembling the foliage of other Apiaceae plants like dill and fennel. The stems are hollow and furrowed, a common trait in this family that helps with flexibility and nutrient transport.

Flowers and Reproduction

The small white or greenish flowers of parsley form compound umbels, a hallmark of Apiaceae. Each flower has five petals and stamens, arranged symmetrically. This flower structure not only aids in identification but also attracts beneficial insects, which helps with pollination.

Aromatic Properties

Parsley’s aroma comes from its essential oils, which serve multiple functions: deterring pests, attracting pollinators, and contributing to its culinary appeal. These oils are chemically similar to those found in carrots and other Apiaceae members, reinforcing their botanical connection.

Evolutionary Origins and Phylogenetic Relations
