 rying to oblong and to linear, narrowed into a short margined petiole or tapering base, 

 or the lowest short and broad on long petioles. Var. HYBRIDA is merely the 

 broader-leaved form. Var. ANGUSTir6LiA (L. angustifolia, Lam.) is a slender 

 branching form, with the upper leaves narrowly lanceolate or'linear, and acute 

 at both ends. Low grounds : not uncommon, especially westward and south- 

 ward. June - Aug. 



7. L. longifdlia, Pursh. Stem ererf, 4-angled, slender (1- 3 high), often 

 branched below; stem-leaves sessile, narrowly linear, elongated (2' -4' long, 2" -3" 

 wide), smooth and shining, rather rigid, obtuse, the margins often a little revo- 

 lute, the veins obscure; the lowest oblong or spatulate; corolla (8" -9" broad) 

 longer than the calyx, the lobes conspicuously pointed. (L. revoliita, Nutt.) 

 Moist soil, Western New York and Pennsylvania to Wisconsin and Illinois. 

 July -Sept. 



4. Introduced European species of true Lysimachia. 



8. L. NUMMUIARIA, L. (MONEYWORT.) Smooth; stems trailing and 

 creeping; leaves roundish, small, short-petioled ; peduncles axillary, 1 -flowered; 

 divisions of the corolla broadly ovate, obtuse, longer than the lance-ovate calyx- 

 lobes and the stamens ; filaments slightly monadelphous at the base. Escaped 

 from gardens into damp ground in some places. July -Sept. 



6. GLAUX, L. SEA-MILKWORT. 



Calyx bell-shaped, 5-cleft ; the lobes ovate, petal-like. Corolla wanting. Sta- 

 mens 5, on the base of the calyx, alternate with its lobes. Pod 5-valved, few- 

 seeded. A low and leafy fleshy perennial, with opposite oblong and entire ses- 

 sile leaves, and solitary nearly sessile (purplish and white) flowers in their axils. 

 (An ancient Greek name, from yXavKos, sea-green.)

 ward. Also beyond the Mississippi northwestward. June. (Eu.) 



7. ANAGALLIS, Tourn. PIMPERNEL. 



Calyx 5-parted. Corolla wheel-shaped, with almost no tube, 5-parted, longer 

 than the calyx; the divisions broad. Stamens 5: filaments bearded. Pod 

 membranaceous, circumcissile, the top falling, off like a lid, many-seeded. Low, 

 spreading or procumbent herbs, mostly annuals, with opposite or whorled entire 

 leaves, and solitary flowers on axillary peduncles. (The ancient Greek name, 

 probably from dvd, again, and crydXAa>, to delight in.) 



1. A. ARVENSIS, L. (COMMON PIMPERNEL.) Leaves ovate, sessile, shorter 

 than the peduncles ; petals obovate, obtuse, fringed with minute teeth or stalked 

 glands. Waste sandy fields. June - Aug. Flowers variable in size, scarlet, 

 sometimes purple, blue, or white, quickly closing at the approach of bad 

 weather; whence the English popular name of "Poor Man's Weather-glass."
