| Distribution | Sandhills only, so far as is known. The only verified record is from Calloway Preserve (TNC) in Hoke County, discovered in 2019. Prior records from Henderson County (East Flat Rock bog) and Cumberland County in the Sandhills (Bonnie Doone area) prove to be C. falcata, due to early blooming time and basal leaves half as broad. All other specimens seen, including in SERNEC, are C. linifolia or C. palustris. Records from BONAP and PLANTS are confused with the latter two species.
Coastal Plain, NC to south-central FL and southern MS; disjunct to low Mountains of northwestern SC and southwestern NC. | |
| Abundance | Extremely rare, with only one known population. The Hoke population consists of about 20 adult stems plus numerous basal leaves. Most stems had been browsed by deer. The website editors recommend a Significantly Rare status, and a State Rank of S1? instead of the NCNHP's current S2S3 that obviously includes other taxa instead of true C. gladiata. | |
| Habitat | Wet, black, mucky soil of blackwater streamhead (Hoke County). Site had burned in 2017. Associates include Tuliptree (Liriodendron tulipifera), Swamp Tupelo (Nyssa biflora), Dichanthelium lucidum, Rhynchospora leptocarpa, Melanthium virginianum, and Lycopus cokeri. | |
| Phenology | Flowering and fruiting early September - early October. | |
| Identification | The very broadly elliptic basal and lower leaves are diagnostic, as they are much broader than nearly all examples of C. linifolia and C. falcata. C. palustris may have stem leaves that wide, but it lacks lower and basal leaves at flowering time. | |
| Taxonomic Comments | Until recently, the taxonomy of this species was very muddled, due to the lumping of C. linifolia within it, either completely or as a variety. Some authors also lumped C. falcata and C. palustris within it, further adding to confusion. See Sorrie et al. (2013) for a discussion of this group of tickseeds. See also Godfrey & Wooten (1981) for descriptions and accurate drawings of these species.
For excellent drawings of all species (except those recently described) and range maps (although now out-of-date), see the monograph by Smith (1976). | |
