Indigen vs. Cultigen: Distinguishing Botanical Origins
In everyday language, the word indigen is often used as a simple variant of indigene, referring to a native inhabitant. However, within the specialized field of botany, the term carries a much more precise scientific meaning. Understanding the distinction between an indigen and a cultigen is essential for grasping how scientists categorize the origins and histories of plant species.

The Botanical Evolution of the Term Indigen
The specific botanical application of "indigen" was established in the early 20th century. It was first utilized in a strictly scientific context in 1918 by Liberty Hyde Bailey (1858–1954), a prominent American horticulturist, botanist, and co-founder of the American Society for Horticultural Science. At that time, Bailey described an indigen as a plant of "known habitat."
Formal Definitions by Liberty Hyde Bailey
By 1923, Bailey refined this concept into a formal definition. He described an indigen as a species where the nativity is known—essentially, a plant that has been recorded somewhere as being indigenous to a specific area.
This definition was not created in isolation; it was developed to provide a clear contrast to another term he introduced: the cultigen. While an indigen is defined by its natural presence in a habitat, a cultigen refers to a species, or its equivalent, that has appeared under the process of domestication. When a plant has undergone such changes through human intervention, it is described as being cultigenous.

| Cultigenous | The state of being a cultigen | Domestication process |
Frequently Asked Questions
What is the main difference between an indigen and a cultigen?
The primary difference lies in their origin: an indigen is a plant with a known natural habitat (indigenous), whereas a cultigen is a plant that has developed through human domestication.
Who defined the term indigen in botany?
The term was defined by Liberty Hyde Bailey, an American botanist and horticulturist, in his works published in 1918 and 1923.
What does it mean if a plant is described as cultigenous?
If a plant is described as cultigenous, it means the plant is a cultigen, implying it has appeared or evolved under the influence of domestication.
Is "indigen" the same as "indigenous" in common usage?
In general usage, "indigen" is often treated as a variant of "indigene" (meaning a native), but in botany, it specifically refers to a species with a documented natural habitat.
How does domestication affect a plant species?
Domestication can transform a species into a cultigen, distinguishing it from its wild, indigenous counterparts through changes resulting from human cultivation.
