Answer: (B)

Purpletop tridens, also known as *Tridens flavus*, is recognized for its distinctive drooping, pyramid-shaped spikelets. This feature is typical of the species and contributes to its overall appearance and identification. The spikelets are arranged in a way that gives them their characteristic shape, which can help differentiate them from other grass species. The drooping nature of these spikelets is particularly notable as they mature, making them easier to recognize in the field. Understanding this key characteristic is important for field identification, as it can assist practitioners in recognizing purpletop tridens amidst other grasses that may have varying flower and seed head structures. This contextual knowledge aids in ecological studies, land management decisions, and conservation efforts where specific plant identification is crucial.
