78 CLASS V. ORDER 1". 



This Lysimachia is distinguishable from the subsequent spe- 

 cies by its broader leaves obtuse at base, and its larger flowers. 

 It rises from one to two feet in height, gives off opposite, oblong, 

 pointed leaves somewhat heart shaped at base. The upper pairs, 

 which have flowers in their axils, are so near together, as to ap- 

 pear quarternate. Petioles fringed with hairs extending round 

 the stem. Flowers in pairs, crossing so near as to appear 

 whorled in fours, yellow. Calyx acute ; segments of the corolla 

 ovate, toothed and mucronated, covered Avith minute glands at 

 base. Anthers sagittate, obtuse ; filaments shorter than the 

 anthers, inserted in a glandular ring at the base of the corolla, 

 with five intermediate, subulate, filamentous bodies covered with 

 glandular pubescence. Germ globose, style straight, stigma 

 simple. Capsule five valved.— Grows on Chelsea beach island. 

 — June, July. — Perennial. 

 Lysimachia hybrida. Mich. Hybrid Loosestrife^ 



Leaves opposite, petioled. lanceolate, acute at base ;• 

 flowers drooping. 



A more common species than the last, which it resembles. 

 Stem erect, with opposite branches. Leaves of the stem long, 

 reflexed, narrow, tapering at both ends. Petioles ciliate as in 

 the former species, the row of hairs extending round the stem. 

 The flowers in every respect resemble those of the preceding 

 species, and indeed I can observe no permanent difference except 

 in the form of the leaves, which are narrow and lanceolate. — 

 Grows among the grass in wet meadows, Roxbury, flowering in 

 July. 



^^ Subgenus Cassandra. Capsule five valved, verrucose ; sta- 

 mens monadelphous, two long and three short.. 



Lysimachia quadrifolia. L. Four leaved Loosestrife. 

 Leaves in lours, nearly sessile, peduncles in fours, 

 one flowered. L. 



A plant of singular regularity, having its long simple stem 

 surrounded by whorls of four oval-lanceolate leaves, with the- 

 same number of yellow flowers on capillary footstalks in their 

 axils. Calyx segments acute, half as long as the corolla. Seg.-
