Culmus

Culmus is primarily a botanical term derived from Latin, referring to the stem or stalk of grasses and related plants. In botany, the culm is the main above-ground axis that supports leaves and bears the inflorescence. In grasses, culms are typically cylindrical, may be hollow or solid, and are segmented by joints called nodes with hollow internodes in many species. Leaves emerge from the nodes along the culm as sheaths that wrap around the stem.

The term culmus is the Latin singular form; in English, the corresponding term is culm, and the plural culms is standard for the English word. The Latin plural would be culmi. Culms vary in size from a few centimeters in small grasses to several meters in bamboos, where the culm is a hollow, woody stalk. The structure and robustness of the culm influence a plant’s height, light capture, and resistance to mechanical stress.

In addition to its botanical sense, Culmus is also the name of an open-source project that develops Hebrew fonts for Linux and other platforms. Culmus Fonts aims to provide high-quality Hebrew typography and is distributed under open licenses. The project is community-driven and has been incorporated into various Linux distributions and font repositories.
