Which tree is a variety of Honeylocust?

The correct answer is Gleditsia triacanthos var. inermis, as it refers specifically to a variety of the Honeylocust tree. Honeylocust, which is commonly planted for its ornamental qualities and shade, is scientifically classified under Gleditsia triacanthos. The variety inermis, also known as the thornless Honeylocust, is particularly valued because it lacks the thorns typical of the species, making it more desirable for landscaping purposes.

In this context, the other options represent different species altogether. Fagus grandifolia refers to the American Beech, which is not related to Honeylocust. Cupressus arizonica is the scientific name for the Arizona Cypress and is also distinct from the Honeylocust family. Lastly, Diospyros virginiana is the Blackgum tree, which belongs to a completely different genus. Understanding the classification and characteristics of plants helps in recognizing their variations and specific uses in horticulture and landscaping.
