or sometimes white, puberulent without, with a wide throat and a 2-lipped limb: upper lip 
arched, notched: lower lip spreading with 2 lateral lobes and a notched middle lobe. 
Stamens 4, included : filaments all anther-bearing : anther-sacs almost parallel. Nutlets 
smooth. 
1. Meehania cordàta (Nutt.) Britton. Stems sparingly hirsute, creeping or ascend- 
ing, 1.5-11 dm. long, commonly branching, producing leafy runners at the base : leaf-blades

9. NÉPETA L. 
Annual or perennial caulescent herbs, with usually pubescent foliage. Leaves oppo- 
site: blades broad, toothed or incised. Flowers in clustered axillary cymes, sometimes
