Cyperoideae

The Cyperoideae is the largest subfamily within the Cyperaceae, commonly known as sedges. These are grass-like herbaceous plants found in wet regions worldwide. The Cyperoideae subfamily typically features bisexual flowers arranged in simple spikes, with scales that are either spirally arranged or in two ranks. This subfamily includes about 70 genera and approximately 2,400 species. Sedges are characterized by their often triangular, solid stems and leaves arranged in three ranks, distinguishing them from grasses which have hollow stems and leaves in two ranks. While many sedges thrive in moist environments like marshes and bogs, they can be found in diverse habitats globally, except for Antarctica.123456
