 drying. Stem 4-8 dm. tall, slender, with many laxly ascending- 

 spreading branches, obscurely striate 4-angled above, nearly terete 

 below, essentially glabrous (sparingly very minutely scabrellous 

 near bases of branches). Leaves opposite or sparingly suboppos- 

 ite above, spreading, or the lower frequently somewhat reflexed, 

 linear, entire, acuminate, those of the stem 2-3.5. cm. long, .5-.9 

 mm. wide; bracts gradually reduced; leaves scabro-roughened to 

 nearly glabrous above. Axillary fascicles scarcely or not devel- 

 oped, when present much shorter than the subtending leaves. 

 Racemes slightly elongated, frequently but one flower of pair 

 developed, 2-9 flowered. Pedicels ascending-spreading, slender, 

 filiform, glabrous, in flower 5-30 mm. long, in fruit 10-32 mm. 

 long, 1.5 to 3 times the length of the bracts. Calyx-tube 3.5-4.5 mm.
