Fam. 175. LABIATAE Shiso Ka Mint Family 



Herbs, rarely shrubs, usually aromatic; stems and branches commonly 4-angIed; leaves opposite or verticillate, simple; stipules 

 absent; inflorescence composed of dichasial or circinnate cymes forming a simulated whorl (verticillaster) ; flowers bisexual, 

 usually bilabiate; calyx 5-toothed, regular or bilabiate; corolla tubular, the limb 4- to 5-lobed, often bilabiate; stamens 4 or 2, 

 inserted on the tube, the anthers 2-locular, often with divergent locules, usually longitudinally split; ovary superior, deeply 



4-lobed; style solitary, gynobasic, usually bifid; ovules 4, erect; fruit of 4 achenelike nudets, the endosperm scanty or absent.
