SCROPHULARIACEAE. 321 



Gratiola virginiana L. Annual; stems erect, branched below, viscid- 

 puberulent or pubescent above, nearly glabrous at base, 10-30 cm. high; 

 leaves sessile, oblong-lanceolate, acute, entire or toothed, usually narrowed at 

 base, 1-2 cm. long, glabrous or nearly so; pedicels slender, equalling the leaves; 

 calyx enclosed at base by 2 foliaceous bracts which equal the lobes; corolla 

 8-10 mm. long, its yellow tube nearly twice as long as the calyx; lobes whitish, 

 the two upper notched; capsule ovoid. 



In muddy places, rare in our limits. 



Gratiola ebracteata Benth. Very similar to G. virginiana but glabrous and 

 the calyx bracts wanting; stems usually simple; leaves somewhat longer, 

 lanceolate, mostly entire, tapering from near the base into a long slender apex; 

 capsule subglobose, obscurely 4-angled. 



Muddy banks of ponds and streams. 



451. SYNTHYRIS. 



Perennial herbs; leaves alternate, crenate or laciniately cleft, 

 the radical roundish or cordate; flowers small, blue, purplish or 

 green, in a spike or raceme; calyx 4-parted; corolla campanulate, 

 with 4 more or less unequal lobes, or none; stamens 2, from just 

 below the upper sinuses, or in one apetalous species on the 

 hypogynous disk, exserted ; stigmas simple; capsule many-seeded. 



Flowers in spikes; leaves cleft into narrow segments. S. pinnatifida. 

 Flowers in racemes; leaves reniform-orbicular. 



Petals and sepals laciniately incised. S. schizantha. 

 Petals and sepals entire. 



Scapes weak, usually shorter than the thin leaves. 5. rotundifolia. 



Scapes stout, exceeding the thick leaves. 5. reniformis. 



Synthyris pinnatifida lanuginosa Piper. Leaves white tomentose, pal- 

 mately 3-7-parted or divided, the segments again cleft; spikes dense, 

 bracteate; corolla whitish, cylindraceous, 4-cleft. 



Olympic Mountains, Flett, not otherwise known. S. pinnatifida Wats, 

 occurs in the Rocky Mountains. 



Synthyris schizantha Piper. Stems 20-30 cm. high; basal leaves reniform- 

 orbicular, somewhat cut-toothed, glabrous above, long-petioled; cauline leaves 

 2, ovate, sessile; raceme viscidly-pubescent; bracts and calyx-lobes as well as 

 the blue petals cleft into narrow lobes. 



Mount Baldy, Olympic Mountains, Canard, Lamb; near Elbe, Cascade 

 Mountains, Flett. Not otherwise known. 



Synthyris rotundifolia Gray. Leaves orbicular-reniform, crenate, somewhat 

 pubescent; flowering stems leafless, 8-12 cm. high, barely exceeding the leaves; 

 sepals spatulate, entire; corolla blue, the petals entire. 



In open dry woods, Chehalis County, Washington, and southward nearly 

 to California. 



Synthyris reniformis Benth. Leaves thickish, glabrous, orbicular-reni- 

 form, crenately many-lobed, the lobes coarsely crenate; petioles longer than 

 the blades; stems stout, exceeding the leaves; flowers blue, on very short pedi- 

 cels.
