 rescence a terminal leafy spike of numerous whorled flowers, crowded 

 upwards, more distant below. Calyx with a short tube, and five 

 nearly equal deeply cut lanceolate teeth, smooth or hairy. Corolla 

 with a cylindrical tube, the upper lip very short, entire, or notched, 

 apparently wanting, the lower a fine deep blue, often streaked with 

 white, reflexed, three lobed, the lateral ones oblong, entire, the middle

This is a variable plant in size, and the greater or less intensity and 

 richness of the colour of its flowers, which are sometimes white or flesh 

 coloured ; the floral leaves or braclea often become of a fine blue 

 colour. It is smooth or hairy, and with or without creeping runners 

 at the base. It is without smell or taste, but the roots are slightly 

 astringent. It was once reputed for its vulnerary property, but is now 

 entirely neglected.
