A close look at the distinctive, bristly texture of a Pincushion Moss (Leucobryum species) found near Lake Trail at Fort Boggy State Park. While often casually identified as Leucobryum glaucum, this is almost certainly its southern sister species, Leucobryum albidum (White Pincushion Moss), which is much more common in East Texas. The moss gets its pale, frosted-green color from a unique leaf structure: the outer layers consist of large, clear, hollow cells that hide the green chlorophyll beneath. When it rains, these empty cells fill with water and turn the cushion bright green; when dry, they fill with air, giving the plant a silvery-white appearance. Fort Boggy State Park. Leon County, Texas, February 21, 2026
Focusing closer, the photograph reveals the intricate, densely packed structure of the cursed buttercup (Ranunculus sceleratus) as it colonizes the dried mud. The plants exhibit a vibrant, fleshy appearance, characterized by deeply lobed, shiny green leaves that vaguely resemble flat-leaf parsley or young celery--giving the plant its alternate name, the celery-leaved buttercup. In this dense thicket, the stout, hollow stems branch frequently, creating a tangled, multi-layered canopy. Tiny, five-petaled pale yellow flowers dot the upper stems, standing out brightly against the dark backdrop of the soil and the deeper green foliage below.
