238 FIGWORT FAMILY. 



G. sphaeroc^rpa. Chiefly S. .- smooth and stouter, with lance-ovate 

 leaves, peduncles scarcely longer than the calyx, and larger spherical pod. 



* * Sterile filaments obvious, usually tipped with a little glandular head in place of 



the anther : leaves shoit. 



G. visebsa. Chiefly S. W. : clammy, with lance-oblong toothed leaves 

 shorter than the peduncles, and whitish flowers. 



■ G. atirea. Sandy wet soil, E. & S. : nearly smooth, with rather narrow 

 entire leaves as long as the peduncles, and golden yellow flowers. 



G. pil6sa. From N. Jersey S. : very different from any of the foregoing, 

 having rigid and simple erect stems and ovate or oblong sessile leaves, both 

 hairy, the flowers sessile, the white corolla hardly longer than the calyx. 



23. SCROPHULARIA, FIGWORT. (Plants a supposed remedy for 

 scrofula.) These homely and insignificant plants hardly ought to have given 

 the name to this large and important family. 



S. nodosa. Damp shady ground : smooth, with 4-sided stem 3° -4° high, 

 ovate or oblong coarsely toothed leaves, and small lurid flowers in loose cymes, 

 all summer. Jl 



24. CHELONE, TURTLE-HEAD (to which the name, from the Greek, 

 refers), SNAKE-HEAD, BALMONY. 



C. glabra, the common species, of wet places; l°-2° high, with lanceolate 

 or lance-oblong leaves on very short petioles, and white or pale purple corolla 

 1 ' or more long, all summer. 2/ 



25. PENTSTEMON. (Name, from the Greek, meaning 5 stamens, 

 refers to the presence of the 5th stamen, which, however, has no anther.) 

 Showy North American and a few Mexican plants, chiefly Western ; two or 

 three are wild E. ; several are in choice cultivation, but few are yet common 

 here. Fl. late spring and summer. ^ 



* Wild E. of the Mississippi, and sometimes cult. : flowers tvhite, commonly tinged 



with some purplish or violet : leaves partly clasping, often serrate : panicle 

 clammy, the corolla slightly so. 



P. pubeseens. Somewhat clammy-pubescent, or smoothish except the 

 panicle, l°-3° high, variable; stem-leaves lanceolate; flowers nodding; the 

 plainly 2-lipped corolla (1' long) with gradually enlarging tube concave on the 

 lower, convex on the upper side, a sort of palate almost closing the mouth ; 

 sterile filament yellow-bearded down one side. 



P. Digitalis. N. Virginia to 111. & S. : taller (20-4°), smooth up to the 

 naked panicle, with wider more entire leaves ; corolla but slightly 2-lipped, 

 open, abruptly inflated bell-shaped above from a narrow tube ; sterile filament 

 sparingly bearded on one side. 



* * Wild beyond but near the Mississippi, showy and cultivated for ornament. 



P. grandiflbrus. Plains from Falls of St. Anthony W. & S. W. : very 

 smooth, pale and glaucous, 10-3° high, Avith thick ovate leaves (I' -2' long) 

 closely sessile and entire, the upper ones rounded, short-pedicelled flowers 

 racemed, lilac-purple oblong-bcll-shaped corolla lJ'-2' long and almost equally 

 5-lobed, the sterile filament nearly smooth. 



P. Cobsea. Plains from Nebraska S. : l°-2° high, stout, with ovate often 

 denticulate thick leaves, a slightly clammy few-flowered panicle or raceme, 

 pale purplish or whitish corolla about 2' long and abruptly much inflated above 

 the narrow base, the border 2-lipped, but the oblong lobes similar ; the sterile 

 filament bearded. 



P. glaber. Plains from Nebraska and Missouri W. : very smooth, com- 

 monly pale or glaucous, with ascending stems 1° - 2° long, lanceolate or lance- 

 ovate entire leaves, and a narrow panicle of very handsome flowers ; the tubular- 

 inflated corolla about 1 1' long, bright pur])le blue, with the spreading lobes
