Carex glaucescens

Carex glaucescens is a perennial sedge that belongs to the family Cyperaceae.[1] The common name of this sedge is the southern waxy sedge due to the blue-grey, waxy appearance of the sheaths and fruits.[2][3] The term "glaucous" means "gleaming" or "grey" in Latin;[4] the specific epithet of C. glaucescens is derived from this term. Carex glaucescens is a native plant in North America and is an obligate wetland species in the Atlantic and Gulf Coastal Plains, Eastern Mountains and Piedmont, and the Great Plains.[1]

Description
Staminate spikelet which fertilizes the pistillate spikelet

Carex glaucescens is a graminoid,[1] meaning they have a grass-like[2] appearance. This species begins blooming in the early summer months, and begins developing fruits into the late summer months around July and August.[3][5] Carex glaucescens features a staminate spikelete at the top of the plant which fertilizes the pistillate spikelets below it.[3] The fruits are born on pendulous pistillate spikelets which are covered by translucent papilla, which gives the fruit sac its glaucous appearance.[3][5] Inside the fruit sac are ellipsoid achenes, the seed of the plant.[3]
