Crabgrass seed head is described as which of the following?

• A. A single spike-like seed head.
• B. Divided into several finger-like segments.
• C. A round umbrel seed structure.
• D. Seed heads are absent.

Answer: (B)

Crabgrass seed heads have a digitate appearance, meaning they spread out from a single point into several slender spikes, like fingers on a hand. This finger-like arrangement is a key identifying feature of crabgrass (Digitaria species) and is what the best description captures. The seed head isn’t a single spike, nor is it a round umbrella-like structure, and crabgrass does produce seeds, so saying seed heads are absent isn’t accurate. In practice, you’ll see multiple slender racemes radiating from one node, typically 3 to 7 or more “fingers,” which is why the description of being divided into several finger-like segments fits crabgrass best.
