Introduction to the Apiaceae Family

The Apiaceae family is widespread globally but is particularly common in northern temperate zones. It is well known for its many edible foods and herbs, including carrots, celery, parsley, dill, and many, many more. Most plants have a characteristic smell and possess small flowers in umbels, making the family fairly easy to spot in the field.

The Apiaceae are part of the Apiales order of core dicot flowering plants. The very closely related Araliaceae family has many overlapping characteristics. In general, though, Apiaceae are usually herbs that produce dry fruits that split into 2 segments when mature (schizocarps), while the Araliaceae are usually shrubs or trees and usually produce berry-like drupes (soft fruits with a pit inside, like a cherry).  

Common Botanical Description

If you’re new to plant morphology, this guide is a great beginner’s description for learning to identify the Apiaceae family, with no need to know any scientific jargon. For researchers or those wanting to learn a more in-depth version, check out the Scientific Botanical Description below.

Leaves and Stems of the Apiaceae: Most plants are aromatic (malodorous to pleasant) annual, biennial, or perennial herbs. Their stems are often hollow between the nodes and are typically grooved or ribbed like celery and are often covered with hairs. The leaves are arranged alternately on the stem and often have sheaths or wrap around the stem. The leaves are often compound, made of many smaller leaflets.

Flowers of the Apiaceae: Flowers are usually rather small but are grouped into often large, flat-topped clusters called umbels for how they resemble the ribs of an umbrella. Each flower typically has five free white or yellow petals, or occasionally pink or purple. Flowers in the center of the cluster are often symmetrical, while those on the outer edge often have larger outer petals and smaller inner petals.

Reproductive Features of the Apiaceae: Flowers are bisexual, with both female (ovary, style, and stigma) and male (stamens) parts in the same flower. There are 5 free (unjoined) stamens. There is a single inferior ovary (located below where the petals attach), with two styles (pollen-collecting tubes) on top that often have thickened bases.

Fruits of the Apiaceae: Fruits are not fleshy but dry “schizocarps” that split into two parts, each containing a single seed when mature.

Uses and Cautions of Apiaceae 

Many members of the Apiaceae family are used for culinary purposes, including Daucus (carrot), Pastinaca (parsnip), Apium (celery), Petroselinum (parsley), Pimpinella (anise), Carum (caraway), Anethum (dill), Anthriscus (chervil), Foeniculum (fennel), and Levisticum (lovage), to name some of the more common ones. Ornamental ones include Eryngium, Angelica, Heracleum, Trachymene, and others; however, many ornamentals have been modified with enlarged bracts or sepals and are not representative of the family.

Many Apiaceae are also used medicinally in folk, herbal, and Chinese medicines to treat a wide variety of ailments.

Still other Apiaceae members have notoriously poisonous resins or alkaloids such as Cicuta, Conium (hemlocks), Aethusa (fool’s parsley), and others are phototoxic (Heracleum mantegazzianum).

Scientific Botanical Description of the Apiaceae

Below is for citizen scientists, researchers, or anyone who wants to dive deeper into the world of botany to learn more about the Apiaceae family. Note that most botanical terms have a hover-over definition to help you better understand what they mean.

Habit & Leaf Form of the Apiaceae

Plants of the Apiaceae are usually soft-stemmed aromatic annual, biennial, or perennial herbs, but some have tough stems, and a few are even woody, tree-like, or shrubby species in the tropics. Stems are hollow between leaf joints and are often ribbed (e.g., Angelica, celery). Sometimes they are switch-plants, occasionally with the principal photosynthesizing function transferred to stems (e.g., Platysace compressa) or phyllodinous (petiole or rachis performs leaf function) (e.g., Lilaeopsis). Leaves are usually well-developed but can be reduced in switch forms. Plants are only occasionally succulent (e.g., Crithmum) and may or may not have a basal aggregation of leaves. They can be helophytic, mesophytic, or xerophytic (e.g., Eryngium). Plants occasionally are conspicuously heterophyllous (e.g., Apium inundatum).

Leaves are small to large and arranged alternately or alternately and opposite (usually just opposite on upper leaves). Leaves are usually herbaceous but may occasionally be leathery or rarely fleshy. Attachment to the stem is either petiolate or sometimes perfoliate or peltate, more or less sheathing; sheaths have free margins and may or may not be pulvinate. Leaves may be gland-dotted and are usually malodorous to pleasant-smelling but are rarely odorless. Leaf arrangement may be simple or compound ternate, imparipinnate, bipinnate, multiply compound, or rarely palmate. When simple, the lamina is usually dissected pinnatifid, but it may also be palmatifid (as seen in Sanicula, Astrantia, and Eryngium), spinose (in Eryngium), or sometimes entire. They are pinnately, palmately, or parallel-veined. Leaves are usually without stipules (but sometimes with stipular flanges).

Flowers of the Apiaceae

Apiaceae plants are usually hermaphroditic but may also be andromonoecious, polygamomonoecious, or dioecious (Acronema). Pollination is entomophilous. Numerous small flowers are almost always in a characteristic flat-topped terminal cymose umbel(s), often compound. Sometimes they are in cymose heads or are rarely reduced to a single flower. Inflorescences may be pseudanthial, often with sterile flowers at the periphery, and may or may not have involucral bracts. Flowers are usually actinomorphic but may be zygomorphic at the umbel edge.

Flowers are usually fairly small, possess bracts, and may be regular to slightly irregular in the corolla. Flowers are usually perfectly 5-merous (except for the gynoecium) and are tetracyclic. Free hypanthium is not present. The perianth usually has a distinct calyx and corolla (but the calyx is often very reduced). The perianth may be sepaline (corolla usually present) or petaline (calyx teeth sometimes present) with 4–10 parts in two (or one) isomerous whorls. The petals are unequal in size, with those pointing outwards from the umbel larger than those pointing in. The calyx, when detectable, has five parts in one whorl that may be free or connate (often reduced to a rim but never forming a tube). Sepals are persistent and may be lobulate, blunt-lobed, or toothed. The corolla also has five parts in one whorl. The white, yellow, pink, or purple petals are always free, valvate, and may be unequal or regular. 

Androecium of the Apiaceae

The androecium has five members (all fertile stamens) that are free of the perianth and each other. They are all equal to or unequal and are found in 1 whorl. Their five stamens are isomerous with the perianth, oppositisepalous, and inflexed in bud. Anthers are dorsifixed or basifixed, introrse, tetrasporangiate, and dehisce via longitudinal slits.

Gynoecium of the Apiaceae

The gynoecium is 2-carpeled, and the pistil is one- or two-celled. The gynoecium is synovarious, median, and inferior. The ovary is 2(1) locular. An epigynous disk is present. Two apical styles are free to partly joined, with their bases thickened into one or two stylopodia that crown the ovary. Stigmas are wet type, non-papillate, and Group IV type. Placentation is either axile or apical. There are 1 or 2 ovules per locule (usually 2 with 1 abortive) that are pendulous and either epitropous or anatropous. Ovules have a ventral raphe, are non-arillate, are unitegmic, and are tenuinucellate or pseudocrassinucellate.  

Fruit of the Apiaceae

The fruits of the Apiaceae are non-fleshy dry schizocarps with 2 mericarps that are united facially. The mericarps are 1-seeded in each part, with the integument sometimes united with the pericarp. Seeds are oily and endospermic.

Taxonomy of Apiaceae

There are 3,820 species in 446 genera in the Apiaceae family of the Apiales order of the core eudicots. Then, the Apiaceae family is further divided into four main subfamilies, with a couple of unplaced genera as well.

1. Apioideae – The largest subfamily and a diverse group of annual to perennial herbs or subshrubs or rarely a small tree. Leaves are usually palmately divided but may be pinnate or simple and entire. Venation is pinnate, but some have parallel venation. Fruits are variable and may or may not be flattened, winged, or ribbed. Cosmopolitan distribution. 
2. Azorelloideae – Annual herbs or small shrubs, often hummock-forming. Leaves are simple, trifid to palmately lobed, and stipulate. Fruit with wings or ribs where the wings or ribs are the largest. Mostly South American, particularly the Patagonia region.
3. Mackinlayoideae – Annual herbs to shrubs. Leaves may or may not be pedately compound, palmate to simple, and are stipulate. Fruit is drupaceous and often laterally compressed. Mostly Old World Tropics.
4. Saniculoideae – A diverse group of annual herbs and subshrubs to trees. Leaves may be tripinnately or palmately compound or simple and often palmately lobed, and some have hairy or spiny teeth. Inflorescences are usually simple umbels or capitula, and bracts may be foliaceous or petaloid. Fruits may be barely to strongly compressed dorsally or laterally, may have 2-3 wings, or may be scaly or spiny. Cosmopolitan distribution.    

Note that Angelica (Apioideae member) looks like it is being split so that the North American species may now/soon be considered Archangelica, while many Eurasian species have been moved to other groups as the genus gets reduced by ~100 species, so I give the species numbers in a range, and the distribution data for the USA and Canada below still call it Angelica until I can get enough sources in agreement.

Apiaceae are both similar to and closely related to the Araliaceae Family, and often, the two can be hard to differentiate. However, some more common differences include the fact that the Apiaceae are usually herbs vs. usually shrubs and trees in the Araliaceae; the leaves that usually lack stipules in the Apiaceae vs. usually present in the Araliaceae; and the fruit is a dry schizocarp with two mericarps vs a berry-like drupe in the Araliaceae.

Distribution of Apiaceae

The Apiaceae family is a cosmopolitan family found all over the globe from frigid to tropical zones. Still, most members of the Apiaceae are in the north temperate zone.
