 to Louisiana. Polymorphous ; the extremes in the following varieties, the first of which 

 verges to the two preceding species. 



Var. hybridum. Cauline leaves mostly petioled, from oblong to broadly linear. — 

 Lysimachia lanceolata, var. hybrida, Gray, 1. u. L. hybrida, Michx. 1. c. L. heterophylla, Ell., 

 Nutty &c. — Commoner northward and westward. 



Var. angustifolium. Stems more branched, a span to 2 feet high : cauline leaves 

 linear, acute at both ends, more sessile, a line or two broad. — L. angustifolia, Lam. 111.

# # Leaves of firmer texture and nearly veinless, mainly sessile : corolla deeper yellow. 

 S. longifolium, Gray, 1. c. Glabrous : stems simple or very sparingly branched, slender, 

 quadrangular, a foot or more high : cauline leaves all narrowly linear and sessile, mostly 

 obtuse (2 to 4 inches long, 1| to 2^ lines wide), lucid, the midrib prominent beneath, the 

 margins narrowly revolute : corolla three fourths inch wide ; the divisions somewhat ob- 

 ovate, longer than the calyx. — S. longifolia ? & S. revoluta, Raf. 1. c. Lysimachia quadriflora,

8. LYSIMACHIA, Tourn. Loosestrife. (In honor of King Lysimachus, 

 or from Xvaie, release from, pa-fr], strife.) — A genus of wide distribution, but 

 very few species in America, and these rather polymorphous. Ours are perennials ; 

 fl. summer. 



§ 1. Lysimachia proper. Corolla yellow, strictly rotate, and deeply parted, 

 with hardly any tube, and no teeth between the lobes : stamens more or less mon- 

 adelphous at base, often unequal in length: leaves opposite or verticillate, or 

 some abnormally alternate. 



# Flowers (middle-sized) in a terminal and naked thy rsoid panicle: corolla destitute of dots and 

 colored streaks : ovules rather numerous. 



L. Fraseri, Duby. Almost glabrous: stem 3 to 5 feet high, sulcate-angled : leaves in 

 whorls of 3 or 4, ovate to oblong-lanceolate, acutely acuminate (3 to 5 inches long), more 

 or less reddish-dotted, mostly acute at base, very short-petioled ; the upper smaller and 

 commonly only opposite : panicle many-flowered, minutely glandular : bracts small and 

 subulate : divisions of the calyx linear-lanceolate, valvate in the bud, margined by a nar- 

 row reddish line, moderately shorter than the obovate obtuse divisions of the corolla : 

 glandular filaments somewhat unequal, united into a cup at base : anthers narrowly 

 oblong, arcuate in age. — DC. Prodr. vii. 65. L. lanceolata, Pursh, Fl. ii. 729, ex herb., not 

 Walt. — S. Carolina (Catesby in herb. Sherard, and Fraser in herb. DC); Columbus, 

 Georgia, Boylcin ; Lookout Mountain, Tennessee, Dr. Allen. A striking and rare species, 

 of the L. vulgaris section, most related to L. Dahurica of N. E. Asia. 



# # Flowers (small) in a virgate terminal raceme or in the upper axils : stem erect: leaves punc- 

 tate with pellucid and at length dark-colored dots : corolla dark-dotted or streaked ; the divisions 

 longer than the narrow lanceolate sepals : filaments conspicuously monadelphous at base and 

 glandular, unequal: anthers barely oblong: capsule 1-5-seeded, sometimes 10-15-ovuled. — 

 Tridynin, Raf. 1. c. L. § Cassandra, Bigel. 1. u. 



L. quadrifolia, L. Stem a foot or two high, simple, leafy throughout, somewhat pubes- 

 cent : leaves in whorls of 4, sometimes of 3, 5, or 6, rarely only in pairs or partly scattered, 

 oblong-lanceolate or the lower ovate, more or less acuminate (1 to 3 inches long), equal, 

 and with flowers on filiform pedicels from most of the upper axils, or sometimes the upper 

 reduced to foliaceous bracts and the flowers loosely racemose : divisions of the corolla
