 to Minnesota and the Winnipeg Valley. 



^_ ^_ H— Styles 3 or 4, very long, distinct and spreading, with capitate stigmas : capsule 

 ovate, strictly 1 -celled, a line or two long : simple or branching herbs, 1 to 3 feet high, with 

 ascending sessile or clasping leaves, and the uppermost branches of the cyme bearing 

 alternate distant flowers. 

 H. virgatum, Lam. Leaves ovate, oblong-lanceolate, or narrowly oblong, acute, ^ to 1 inch 

 lono-, 2 to 4 lines wide : flowers briglit yellow, 4 to 8 lines broad, in nearly naked cymes : 

 sepals lanceolate to ovate, acute or acuminate, keeled l)elow, more or less foliaceous and en- 

 closino- the small capsule. — Diet. iv. 158 ; Chois. 1. c. 547 ; Torr. & Gray, Fl. i. 166. H. an-

 Grav Man. ed. 5, 85. H. hedyotifolium, Poir. Suppl. iii. 700. — Sandy or rocky ground, from 

 tlie "pine barrens of New Jersey to the mountains of Georgia, Tennessee, and Kentucky. 

 The species is ijuite variable in the size and form of its leaves, but the general type is oblong- 

 lanceolate, about an inch long and three lines broad. The following varieties can be recog- 

 nized usually without difficulty : 



Var. OValifolium, Britton. Leaves oval to obovate, not more than twice as long as 

 broad, mostly obtu.se, rather strictly erect or almost appressed. — Trans. N. Y. Acad. Sci. ix. 



10. Pine barrens of New Jersey. The short broad usually erect and distant leaves give 



to the plant an aspect quite different from that of the more southern species. Apparently 

 the common form of the New Jersey pine liarrens, the species proper appearing with great 

 distinctness only farther south. 



Var. acutif olium, Coulter. Usually taller and more branching, with leaves linear- 

 lanceolate, tapering to a very acute apex, an inch or more long, and a line or two broad. — 

 Bot. Gaz. xi. 106. H. acutifolium, Ell. Sk. ii. 26; Torr. & Gray, Fl. i. 167. — From South 

 Carolina to Florida. 

 H. pilosum, Walt. Scabrous-tomentose, mostly simple : leaves ovate-lanceolate, strictly 

 erect or even appressed, 4 to 6 lines long, 1 to 2 lines wide, sometimes much reduced : flowers 

 3 to 5 lines broad, in few-flowered cymes : sepals ovate-lanceolate, acute : petals more than 

 twice as long, involute when old. — Car. 190; Chois. 1. c. 549; Torr. & Gray, Fl. i. 163; 

 //. setosum, L. Spec. ii. 787, as to Clayton's plant in Gronov. Virg. 88. //. simplex, Michx. Fl. 

 ii. 80 ; Chois. 1. c. Ascyrum viUosum, L. Spec. ii. 788. — Wet pine barrens, South Carolina 

 to Florida and Louisiana. 



H_ 4— ^— -1— Styles 3, long, distinct, and usually spreading, with capitate stigmas : capsule 

 ovate, 3-celled, more or less covered with amber-colored glands and exhaling a heavy odor 

 when crushed : petals marcescent : whole plant (including petals and anthers) more or 

 less black;dotted : herbs, with rather large leaves and flowers, the petals much longer 

 than the sepals. 



•H- Eastern species : plants 1 to 4 feet high : capsules mostly not lobed. 



H. PERFORATUM, L. Much branched (usually a leafy branch in the axil of every leaf of the 

 primary stem) : leaves linear to oblong, obtuse, mostly tapering at base, i to 1 inch long, 1 

 to 5 lines wide : flowers numerous in loose cymes, about an inch broad : sepals linear-lanceo- 

 late, very acute or acuminate : petals bright yellow, black-dotted along the margin : capsule 

 conical-ovate, 2 to 3 lines long. — Spec. ii. 785. — Common everywhere in old fields as a weed 

 difficult to extirpate. (Nat. from Eu.) 



H. maculatuni, Walt. Simple below, more or less branched above, conspicuously dotted 

 all over : leaves oblong- to lance-ovate, or even cordate-ovate, obtuse or acute, more or less 

 clasping, sometimes tapering at base, 1 to 3 inches loug, 4 to 9 lines broad : flowers smaller, 

 3 to 6 lines broad or even less, usually crowded : sepals lanceolate to ovate, acute : petals 

 pale yellow, with black lines as well as dots : capsule conical-ovate, 2 to 3 lines long, often 

 thickly covered with conspicuous amber-colored glands. — Car. 189 ; Michx. Fl. ii. 80 ; Torr.
