 cised-serrate or deeply incised : panicles narrow : calyx-lobes ovate, acute or obtuse : 

 corolla lustrous without, 8-10 mm. long, the upper lip as long as the tube : sterile filament 

 greenish yellow : capsules conic-ovoid or conic, 7-10 mm. long, attenuate to the apex. 



On hillsides or in open woods, Connecticut to Minnesota, south to North Carolina and Nebraska. 

 Spring and summer. 



5. Scrophularia occidentalis (Rydb. ) Bicknell. Similar to 8. leporella in habit, 

 but with densely glandular panicle-branches. Stem more or less glandular: leaf -blades 

 ovate to lanceolate or oblong-lanceolate, incised or incised-serrate, those of the lower leaves 

 especially, hastately incised at the base : corolla 8-10 mm. long, the upper lip much 

 shorter than the tube : capsules ovoid, 7-8 mm. long.

 Summer.^ 



9. CHELONE L. 



Perennial caulescent herbs, with glabrous or nearly glabrous foliage. Leaves opposite : 

 blades flat, toothed. Flowers in dense terminal spike-like racemes. Calyx subtended by 

 sepal-like bracts : lobes 5. Corolla irregular, white, cream, rose-purple or red, dilated 

 into a quite ample throat, the upper lip concave, exterior in the bud ; the lower lip pubes- 

 cent within, with 2 lateral lobes larger than the middle one. Stamens 4 : filaments pubes- 

 cent, the sterile one small : anthers woolly. Styles united. Ovules numerous. Capsule 

 ovoid. Seeds flattened, winged. The plants flower in summer and fall. TURTLE-HEAD. 



Calyx-lobes and bracts glabrous, not ciliolate : corolla white or cream-colored. 



Leaf-blades sessile and somewhat clasping. 1. C. Cuthbertii.
