Which of the following characteristics is most common to Eragrostis spp?

• A. Spikelets that are awnless with ≥ 2 florets each
• B. Spikelets that contain only a single flower
• C. Clusters of flowers with deep indentations
• D. Densely packed spikes with prolonged flowering

Answer: (A)

The characteristic that is most common to Eragrostis spp. is that they have spikelets that are awnless with two or more florets each. This genus of grasses typically features spikelets arranged in a distinctive manner where the absence of awns is a distinctive trait, aiding identification. The presence of multiple florets per spikelet contributes to the overall flowering structure and reproductive strategies of the plant, allowing for an effective pollination process and seed production. This structure also correlates well with the habitat preferences and ecological adaptations of Eragrostis species, making them more suited to the environments they inhabit. Understanding this specific characteristic helps in distinguishing Eragrostis from other grass genera, where spikelet configurations can vary significantly.
