The overall body colour of this tongue is purple, indicating blood stasis. It is predominantly Reddish-Purple, which indicates blood stasis deriving from or associated with Heat but the chest area on the right of the tongue is Bluish-Purple which indicates that there is also some Cold which has lead to blood stasis in the chest.

The tongue is also stiff. A stiff tongue indicates either severe blood stasis or internal Wind. As the tongue is also purple, in this case it is most likely that it indicates blood stasis. 

The sticky consistency of the coating simply indicates that there is Dampness (or together with the Swollen tongue body Damp-Phlegm), but the fact that it is rootless reflects a deficiency of Stomach-Yin. A rootless coating reflects the beginning stages of Stomach-Yin deficiency.
