Description
A description of Carex retroflexa is provided in The Flora of North America. This species is similar to C. texensis, but can be told apart by having an perigynium wider than 1.3 mm and a spongy layer more than 1.1 mm.[2]
Distribution
Ranges from Texas to Kansas to Iowa, east to Indiana and Michigan, north to Quebec and Maine and south to the gulf coast states.[2]
Ecology
Habitat
This species has been found along rivers in rich deciduous woods and in floodplains surrounded by wet sphagnum moss. It has also been observed growing alongside trails at the edge of woodlands. It does well in partial to deep shade environments in drying sandy loam of floodplains.[3]
Associated species include Carex albolutescens, Carex atlantica, Carex complanata, Carex lurida, Carex venusta, Carex capillacea and sphagnum species.[3]
Phenology
C. retroflexa has been observed flowering in April and May and fruiting from March to May.[3][4]
Diseases and parasites
The introduced earthworm Lumbricus terrestris significantly decreases the growth of C. retroflexa by decreasing the number of culms.[5]
