The personate or mask-like corolla is rather indefinite in form : the type 

 of it occurs in Antirrhinum (fig. 201), which approaches the labiate form ; 

 but the throat is closed by a gibbous projection (forming the palate), 

 giving the front view the appearance of a mask with a broad-lipped 

 mouth.
