 ally sparingly branciied : leaf-blades ovate, oval-hastate or lanceolate, 5-20 cm. long, in- 

 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 S. 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. 



In low grounds and thickets. South Dakota to the Indian Territory, Washington and California 

 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 1)y 

 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. 



Leaf-blades manifestly petioled. 2. C. glabra. 

 Calyx-lobes and bracts piiberulent, or at least ciliolate : corolla pink or rose-purple. 



Corolla pink : campestrian species. 3. C. obltqua. 



Corolla rose-purple : Alleghenian species. 4. C. Lyonii. 



1. Chelone Cuthb6rtii Small. Stems 5-11 dm. tall, simple : leaf -blades lanceolate 

 to narrowly linear-lanceolate, long-acuminate, 4-10 cm. long, finely or shallowly serrate, 

 truncate or cordate, and somewhat clasping at the base : racemes few-flowered, 3-8 cm. 

 long: bracts glabrous: calyx-lol^es broadly oblong to oblong-obovate, 7-8 mm. long: co- 

 rolla cream-colored, 2-2.5 cm. long, the lower lip copiously bearded within : capsules ovoid,
