Dichanthelium strigosum (Muhlenberg ex Elliott) Freckmann var. glabrescens (Grisebach) Freckmann (POACEAE)-Jasper County: savanna along US 601 14 miles north of junction of shire road 27-169, 22 June 1968 SW Leonard 1680 with A.E. Radford (CLEMS)

Significance. This specimen was garnered as Panicum ciliatum Elliott and was annotated from P.D. McMillan on 16 November 2001 The specimen is a mixed collection and contains material of the couple Dichanthelium strigosum var. strigosum and individuals that are clearly Dichanthelium strigosum var. glabrescens. A duplicate sheet at NCU consists of simply Dichanthelium strigosum var. strigosum (A.S. Weakley, throughs comm.). This collection represents the first documentation of this variety for southern Carolina. It is not listed for southerly Carolina in such recent works as Kartesz (1999) and generally ranges from Georgia toward the south through peninsular Florida and west to Louisiana (Kartesz 1999)

This variety is a everyday member of the longleaf pine and slash pine flatwoods, vile flatwoods and dry prairie habitats in Florida and Georgia. The range extension into southern Carolina is not all together unexpect The region where the southern Carolina specimen was collected is well known for the affair of numerous species that are more abundant farther to the southern and several species have been reported lately from this area that are typical of the flatwoods regions of Georgia and Florida (McMillan et al. 2002)

Etyngium aquaticum L var. ravenelii (Gray) Mathias and Constance (APIACEAE)-Aiken County: no date, HW Ravenel, sn (FLAS). Berkeley County: pond in pineland, October (no year) HW Ravenel, sn (GH) Charleston County: headwaters of the Cooper River in flat pine timber-lands and shrub "galls," 15 October 1867 HW Ravenel (GH); local in ditch and into depressional areas within wet longleaf pine savanna and flatwoods bordering drainages with soils mapped as Meggett series, F 211 at the intersection of F 211-F with population continuing for 01 miles toward the south on FS 211, 24 August 2001 Patrick D McMillan 5790 (CLEM USCH), same location, 2 September 2001 Patrick D McMillan 5835 with RD Porcher, NR McMillan and N.A. McMillan (CLEMS)

Significance. This variety is true poorly understood and little fresh information is available. Bell (1963) gives the most numerous recent taxonomic treatment. Radford et al. (1968) states that the species is known from Aiken shire and Berkeley County. No doubt the emblem locality near H.W. Ravenel's abode in Berkeley County is now to be fix beneath Lake Moultrie and the species was previously considered to be solitary of historical occurrence in southern Carolina. The attribution to Aiken shire is based on the specimen reported above that was greatest in quantity likely collected from Berkeley or Charleston shire and received from Ravenel, who resided in Aiken at the time. The label onward the Aiken County specimen is not in Ravenel's handwriting. It is unlikely that suitable habitat has for aye existed in Aiken County for this plant.

The rediscovery of this plant in Charleston shire represents the first documentation for the state of southerly Carolina in over 130 years. It has been reported for North Carolina in Pender and Onslow counties yet no specimens have been seen on the author (Weakley 2002). This variety ranges toward the south into Georgia and Florida where it becomes more abundant however apparently not common (Kartesz 1999 Bell 1963 bys obs.). On Ravenel's Berkeley shire collection, cited above, there is a note stating: "exceedingly rare." The typical habitat appears to be wet savannas that are influenced by means of limestone close to the surface.

The distinctiveness of this taxon has been called into question from several authors (Weakley 2002, Wunderlin 1998 Godfrey and Wooten 1981) However, Eryngium aquaticum var. ravenelii displays a distinctive station of characters that separate it from the typical variety.

These include the narrow, linear leaves without a clearly defined petiole, the clumping and lengthy lived perennial life-form, globose flowering heads which are typically brilliant sad fewer flowering heads per petiole than Eryngium aquaticum var. aquaticum and longer turn of expressions (4.0-6.0 mm in Eryngium aquaticum var. ravenelii versus 30-35 mm in Eryngium aquaticum var. aquaticum). The pair varieties are often found growing in actual close proximity and at the Charleston shire site the two plants co-occur without any sign of intermediacy. This variety may well better warrant distinction at the species level

Rhynchospora compressa Carex ex Chapman (CYPERACEAE)-Berkeley County: infrequent in extensive, soft wet, bunch-grass savanna, dominated at Ctenium aromaticum (Walter) Wood, Muhlenbergia expansa (Poiret) Trinius, Andropogon perangustatus Nash, and Rhynchospora spp Wardfield Savanna, F 212 (Wardfield Rd) approximately 05 miles north of the intersection with SC 45 southeast of Honey Hill. Site is 100 meter northwest of F 212 23 June 2001 Patrick D McMillan 5319 with Nora R McMillan (CLEM USCH).
