. Common plants of longleaf pine-bluestem range. Plant ecology; Grasses; Forage plants. PAINTBRUSH BLUESTEM Andropogon ternarius Michx. Paintbrush bluestem is a common associate of pinehill bluestem, especially on well-drained sandy sites. The two grasses look nearly alike until flower heads emerge in early fall. Racemes of paintbrush bluestem are paired, however, and are much thicker and showier than those of pinehill, which has only one raceme terminating each inflorescence branch. During winter, spring, and summer, persistent old seedstalks are the best character for distin- guishing paintbrush bluestem. A conspicuous paint- brushlike tuft of hairs remains on the branch tips after racemes shatter, and old-growth basal leaves are curly. It is also a true bunchgrass, while pine- hill bluestem is rhizomatous. Paintbrush bluestem is similar in forage value to pinehill bluestem. Because it is seldom abun- dant, however, it contributes little to the cattle diet. Range: Coastal Plain, Delaware to Texas, and inland on dry, sandy soils to Kentucky and Kansas. Perennial. Culms in tufts. 80-120 cm. tall, simple below and much branched above; sheaths shorter than the inter- nodes, glabrous to densely hirsute near the base; ligule 1 mm. long, membranous; blades 2-4 mm. wide, the lower long and curling on drying; racemes in pairs, occasionally in threes, 3-6 cm. long, silvery-silky with long hairs, more or less exserted on long slender peduncles from slender spathes; sessile spikelet 5-6 mm. long, the twisted and bent awn cm. long; pedicellate spikelet a scabrous scale 1 mm. long on a densely villous pedicel almost as long as the sessile Paintbrush bluestem 11.
