alternating opposite pairs on slender stems. The 
small, violet, purple, or rarely white, hooded, tubular 
flowers are gathered in dense terminal spikes, suggesting 
a Clover head. They are strongly and irregularly 
two-lipped. The darker toned and deeply arched upper 
lip is hood-like. The spreading lower lip is three- 
lobed, with the edge of the middle and longest lobe, 
fringed. The four unequal stamens and pistil show

is deeply cleft into two unequal parts, and is guarded

this plant formerly had a reputation for curing throat 
diseases. It has also been used in healing wounds, 
and for making a gargle for sore throats.
