Steins short, 1-2 dm. tall, often none, sometimes with one 

 or two leaves, but usually much branched from the base and 

 leafless, pale yellowish-green, apprcssed-pilose; leaf-blades 

 linear-lanceolate, 5-15 cm. long, 5-15 mm. wide, somewhat 

 curved, attenuate, softly appressed-pilose below, and ciliate 

 with long hairs. Sheaths large, thin, inflated, the upper 

 very short, all very smooth, except the uppermost; bracts 

 of the involucre 2, very broad and saccate at the base, 

 shorter, or sometimes longer than the leaf-blades, pilose 

 below with long hairs, above with short hairs. Cymes about 

 10- to 30-flowered; pedicels 2-4 cm. long, densely pilose with 

 whitish hairs; sepals linear-lanceolate, obtuse, 6-8 mm. long, 

 densely pubescent; corolla small, pale blue. — Sandy soil, 

 Eastern Texas. Spring.

Stems erect, simple, slender, sometimes branched, 2-4 dm. 

 tall, pilose with long spreading white hairs; leaf -blades long- 

 linear, acuminate, flat or rarely conduplicate, hairy like the 

 stems; bracts of the involunce 2, very unequal, hairy like 

 the leaves, and resembling them, minutely ciliate on the 

 margins. Cymes about 10- to 15-flowered; pedicels 2-3 cm. 

 long, densely pilose with simple white hairs; sepals linear- 

 lanceolate, obtuse, 8-10 mm. long, densely pilose with simple 

 white hairs; corolla small, deep blue or purple. — Low rich 

 woods, Texas to Mississippi. Spring.

 narrower leaves, pilose stems, and smaller flowers. — Probably 

 is the Southern representative of T. Virginiana.
