Ozark Phlox Plant a glandular-pubescent or rarely glabrate perennial with short thickish rootstocks; stems single or often several from one crown, simple or somewhat branched, thickish, averaging 40 cm. tall, with 6 to 10 nodes up to the inflo- rescence; leaves opposite or the uppermost alternate, thinnish, acute to acumi- nate, passing from linear at the base of the stem to oblong-lanceolate or broadly ovate and cordate-clasping, on the average 60 mm. long and 15 mm. wide, just below the inflorescence; flower* borne in small cymes grouped in a rather lax corymb or panicle; bracts conspicuous, the lowermost similar to the upper leaves; sepals narrow, to mm. long, united into a tube for about 1/3 their length, and tipped with an awn 1 to 2 mm. long; corolla-tube 12 to 16 mm. long, usually pubescent, the lobes obovate, about 12 by 8 mm., terminally obtuse or somewhat apiculate; corolla-color phlox-purple through- out some colonies, near-white throughout others, both extremes together with intermediate hues appearing in still other colonics; eye often pale, and marked with 2-3 conspicuous striae at the base of each lobe, ranging in hue from tyrian rose through purple to violet; stamens rather short, the anther-tips lying below the corolla-tube orifice at average depths of 2, , 4, 6, and 7 mm. respectively; styles short and about half-united, the compound style averaging 1 mm. in length, and the stigmas slightly longer or rarely shorter.
