 what saccate bases, these often 4-5 cm. broad ; stem-leaves sheathing by the broad bases,

 abruptly pointed : sepals linear-lanceolate, 15-17 mm. long, acute : petals violet-blue, much

 like at maturity, conspicuously ciliate ; stem-leaves with sheathing bases : spikes simple, 

 3-10 cm. long : bracts imbricated, acute, 2-ranked, about 2 cm. long : sepals becoming 1.5
