INTRODUCTION This paper is the 6th part of an inventory, based on available voucher specimens, of the vascular flora of the Big Thicket National Preserve in southeastern Texas. In 5 previous papers, we provided annotated checklists of the Hickory Creek, Turkey Creek, Big Sandy Creek, Lance Rosier, and Beech Creek units (MacRoberts et al. Brown 2002; et 2005, 2006a, 2006b, 2008). At this time, the Menard Creek Unit has been inventoried, and al. a paper is anticipated in the near future. Here, we provide an annotated checklist of the Loblolly Unit. AND METHODS SITE The Big Thicket located in the West Gulf Coastal Plain in southeastern Texas Diggs 2006 is (see et al. for and Peacock literature description). (1994) reported 12 units for the Big Thicket National Preserve. Since then the Big Sandy Creek Corridor (1,798 hectares), the Canyonlands (350 hectares), and Village Creek Corridor (2,059 hectares) have been added. The addition of these 3 units has added 4,207 hectares to the 34,000 reported by Peacock in 1994. However, Deanna Boensch, Big Thicket ecologist comm.), fire (pers. now indicated the total hectares are 40,088. The units range from 222 to 10,000 hectares and are scattered over 7 Texas counties. The Loblolly Unit consists of 222 hectares in Liberty County (Fig. 1). It is located on the Beaumont formation on Aldine-Aris/Gyron-Aldine, Vamont, and Waller and topographically soils, is flat, and poorly drained with very slow permeability (Deshotels 1978; Aronow 1981; Shelby et 1992; al. Griffith 1996). Elevation about 30 meters. After heavy rain standing water present in the flatwoods is falls, is for extended periods of time. The Unit consists of basically plant community complex: Floodplain and/ 1 & Hardwood common or Flatland Marks Harcombe Forest, a association in the area (Ajilvsgi 1979; 1981; Bezanson 2000). 2006). However, others have questioned this interpretation maintaining that has always been Flatland al. it & Hardwood although may have been (Harcombe Marks Our Forest cleared in the past 1979). study of it the Loblolly Unit found no prairie species or any remnant prairie habitat. Therefore, the flora is clearly a & & Hardwood (Harcombe Marks Marks Harcombe Flatland Forest 1979; 1981). Like units of the Big Thicket National Preserve, the Loblolly Unit has not previously been the subject all of a detailed floristic inventory. known Because our purpose is to produce a list of taxa to occur on the Loblolly Unit, a vouchered A specimen was considered to be the only evidence acceptable for inclusion in the total of 471 herbarium list. specimens form the data for this report.

It is separated from the similar Q. jalcata by the longer erect branched on On hairs the abaxial surface of the shade leaves. Q. jalcata these trichomes are smaller and appressed [see the key in Smith (1994)]. Echinochloa colonum. Most books use Ward specific epithet. See (2005) for this change in ; orthography.

(2006) consider the Hardin County specimen to be from a plant cultivated as a lawn grass. For now, the only east Texas collec- tions of native plants are from Liberty County in the Trinity River National Refuge and the Loblolly Unit. The plants were frequent along the southern edge west from the junction with C.R. 2071. Additional specimens SBSC at are from the various units of the National Wildlife Refuge complex in Brazoria County. DISCUSSION There are 88 families and 201 genera for the 305 taxa (271 native) on the Loblolly Unit Eight families, list. Poaceae Cyperaceae Asteraceae Scrophulariaceae Apiaceae (42 taxa), (36 taxa), (31 taxa), (11 taxa), (10 taxa), % Lamiaceae (9 taxa), Fagaceae (8 taxa), and Fabaceae (7 taxa) account for 50 of all taxa collected. We compared the present list of species for Loblolly Unit with the species reported by Turner et al. % (2003) in their Atlas the Vascular Plants Texas and found that 115 taxa, 37.7 of the species on the of of County Loblolly Unit are not reported in Liberty in that source.
