6. Veronica scutellata L. 1. c. 12. Glabrous or very sparingly hairy; stems 

 slender, ascending from a stoloniferous base, 3-5 dm. long: leaves sessile, 

 linear or linear-lanceolate, acute, remotely denticulate, 5-7 cm. long: flowers 

 scattered on filiform, elongated, and widely spreading pedicels: corolla blue or 

 purple, 4-6 mm. broad: capsule broader than high, very flat, deeply emar- 

 ginate at the summit, slightly so at base; seeds flat. Wyoming, northward, 

 and thence across the continent. 



10. LIMOSELLA L. MUDWOET 



Small glabrous plants, with fibrous roots, a cluster of entire fleshy leaves 

 at the nodes of the stolons, and short scape-like naked pedicels from the 

 axils each bearing a small white or purplish flower. Calyx campanulate. 

 Corolla rotate-campanulate, 5-lobed, and nearly regular. Stamens 4, no 

 sterile filament; anther-cells confluent. 



1. Limosella aquatica L. Sp. PI. 631. 1753. Tufts 3-6 cm. high: clustered 

 leaves exceeding the pedicels, when scattered on sterile shoots alternate, in 

 the typical form with a spatulate or oblong blade on a distinct petiole, which 

 in mud remains short but in water elongates to 5-12 cm. : corolla pink or white, 

 scarcely surpassing the calyx: capsule obtuse, surpassing the calyx. Muddy 

 flats and shores, margins of brooks; widely distributed in America and Europe. 



11. GERARDIA L. 



Erect branching herbs with stem leaves opposite (or the upper alternate) 

 and uppermost reduced to bracts subtending 1-flowered peduncles which 

 often form a raceme or spike of showy purple or yellow flowers. Calyx cam- 

 panulate, 5-toothed or 5-cleft. Corolla campanulate, funnelform, or somewhat 

 tubular, enlarged above. Stamens strongly didynamous, hairy, included; the 

 2-celled anthers approximated by pairs, and the cells parallel and often pointed 

 at base. Style elongated, mostly flattened and enlarged at apex. Capsule 

 globular or ovate-pointed. 



Capsule oblong; corolla pubescent on the outside . . . . 1. G. aspera. 

 Capsule globose; corolla glabrous 2. G. Besseyana. 



1. Gerardia aspera Dougl., Benth. in DC. Prodr. 10: 517. 1846. Stems 

 and branches strict, 3-5 dm. high: leaves rather erect, strongly hispidulous- 

 scabrous, all filiform-linear: pedicels mostly equaling and sometimes mod- 

 erately exceeding the calyx, erect: calyx-lobes triangular-ovate or triangular- 

 lanceolate, acute, mostly less than half as long as the tube: corolla purple, 

 25 mm. long, pubescent externally: anthers obtuse at base; filaments villous: 

 capsule surpassing the calyx. From Colorado eastward and southward. 



2. Gerardia Besseyana Brit. Mem. Torr. Club 5: 295. 1894. A strict 

 annual 3-6 dm. high: leaves linear, about 25 mm. long, acute, scabrous,
