What is a characteristic feature of Dallisgrass (Paspalum dilatatum)?

Dallisgrass (Paspalum dilatatum) is characterized by its smooth stems. This trait is an identifying feature of the plant, which differentiates it from various other grass species that may exhibit rough or hairy stems. The smoothness of the stems contributes to the overall aesthetics of the grass and can be observed when looking at the plant in its natural habitat or during identification efforts in vegetation management.

In addition to the smooth stems, Dallisgrass has other characteristics that contribute to its identification, such as its growth habit and leaf structure. However, the smoothness is particularly notable when assessing the plant's features. Other options listed, like a thick woody trunk or highly fragrant flowers, do not align with the botanical characteristics of Dallisgrass. Additionally, while the plant does have leaves, they are not deeply lobed, which further clarifies why smooth stems is the specific characteristic feature of Dallisgrass.
