Zeugiteae

Zeugiteae is a small tribe of grasses within the subfamily Panicoideae of the Poaceae family. This tribe is characterized by its perennial habit and distinctive inflorescence structure.

Characteristics:

Zeugiteae grasses are typically perennial, meaning they live for more than two years. They often exhibit rhizomatous growth, spreading via underground stems. The inflorescence, or flower head, is typically a panicle or raceme, bearing spikelets that are laterally compressed. Florets are often bisexual, containing both male and female reproductive parts.

Distribution:

The grasses in the Zeugiteae tribe are primarily found in the Americas, with a concentration of species in tropical and subtropical regions.

Genera:

The tribe Zeugiteae comprises a limited number of genera, including:

• Zeugites
• Lophaspis (sometimes included in Zeugites)

Taxonomy:

The taxonomic placement of Zeugiteae within the Panicoideae has been the subject of some debate. Morphological and molecular data have been used to understand the relationships between Zeugiteae and other tribes within the subfamily.

Economic Importance:

Species within Zeugiteae are not generally considered to be of significant economic importance as forage crops or grain crops. Their primary importance is in their role within natural ecosystems.
