Rank Reasons

Clematis catesbyana is a vining perennial herb that occurs in the eastern United States, where it has a disjointed distribution on the Atlantic and Gulf Coastal Plain and at more inland sites where it is most common in the southern Ozarks. It is relatively uncommon elsewhere.

Range Extent Comments

Clematis catesbyana occurs in the southeastern United States from southeastern Virginia to central peninsular Florida and west to Louisiana on the Coastal Plain. Inland occurrences are found in central Kentucky and Tennessee and northern Arkansas and southern Missouri, southwestern West Virginia, and in the Ridge and Valley of Virginia and McDowell County, and North Carolina, on a dolomite window in the Blue Ridge (SE RSGCN Workshop 2022, Weakley and Southeastern United States 2022). Range extent was estimated with GeoCAT using occurrence and photo based observation data (Bachman et al. 2011, GBIF 2022, iNaturalist 2022, SEINet 2022). This species is possibly extirpated in Oklahoma.

Occurrences Comments

Based on NatureServe Network occurrence data, herbarium records, photo-based observations, and anecdotal evidence, there are between 81 and 300 occurrences rangewide (GBIF 2022, iNaturalist 2022, NatureServe 2022, SEINet 2022). This species is rare to uncommon across most of its range, except Arkansas and southern Missouri (Weakley and Southeastern Flora Team 2022). It is most common in the southern Ozarks.

Ecology & Habitat

Habitat

This species occurs on well-drained substrates in open or disturbed sites with sandy soils or on limestone outcrops of dunes and interdune swales, calcareous woodlands and hammocks, thickets, and glades at elevations ranging from 0 to 1,200 m (Weakley and Southeastern Flora Team 2022, FNA 1997). This species can be weedy with light disturbance.
