soon 1807 proposed earlier but not established, 

 and objectionable formed from Stachys. Genus 

 now generally adopted aud easily known by the 

 habit of spiral flowers. The lip is unguic. bi- 

 callose paralel, anther peduncled 4'C. It is very 

 prolific in species, not yet well distinguished and

 &/C. but I add here some exotic species.
