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

10. LIMOSELLA L. Mudwobt 



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 purpUsh flower. Calyx campanulate. 

 Corolla rotate-campanulate, 5-lobed, an'd nearly regular. Stamens 4, no 

 sterile filament; anther-cells confluent.

 lea,ves 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. 6ERARDIA L. 



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

 and uppermost reduced to bracts subtendmg 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 approximate* 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.

 erately exceeding the calyx, erect: calyx-lobes trianguliar-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 caljrx. — ^From Colorado eastward and southward.
