288 JIYPERICACE^. Hypericum. 



Fl. Philad. ii. 14, not Michx. — Moist ground, from Canada to Pennsylvania and westward 

 to Minnesota and the Winnipeg Valley. 



^_ ^_ ^— 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 iierbs, 1 to 3 feet high, with 

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

 alternate distant Howers. 

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

 long, 1 to 4 lines wide : flowers brigiit yellow, 4 to 8 lines broad, in nearly naked cymes : 

 sepals lanceolate to ovate, acute or acuminate, keeled below, more or less foliaceous and en- 

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

 guhsHin, Michx. in Willd. Spec. iii. 1454; Chois. 1. c. 546; Torr. & Gray, 1. c. 164, 673; 

 Grav, Man. ed. 5, 85. //. hedijoti/olium, I'oir. Suppl. iii. 700. — Sandy or rocky ground, from 

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

 The species is quite 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 ditliculty: 



Var. ovalifolium, Hm ttox. Loaves oval to obovate, not more than twice as long as 

 broad, mostly obtuse, rather strictly erect or almost ajipressed. — Trans. N. Y. Acad. Sci. ix. 

 10. — Pine barrens of New Jersey. The short broad u.sually erect and distant leaves give 

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

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

 distinctness only farther south. 



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

 lanceolate, ta])ering to a very acute apex, an inch or more long, and a line or two broad. — 

 Hot. (;az. xi. 106. //. acutifoUum, 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 appre.ssed, 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; 

 //. sctosum, L. Spec. ii. 787, as to Clayton's plant in Gronov. Virg. 88. //. si'm/i/cr, Michx. Fl. 

 ii. 80 ; Chois. 1. c. Asci/rum villosum, L. Spec. ii. 788. — Wet pine barrens, South Carolina 

 to Florida and Louisiana. 



^— -1— -t— -t— 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 odf)r 

 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. 



++ Eastern species : plants 1 to 4 feet high : capsules mostly not lobed. 



H. perfouAtum, 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, ^ 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. maculatum, Walt. Simple below, more or less branched above, conspicuously dotted 

 all over : loaves oblong- to lan<-e-ovate, or even cordate-ovate, obtuse or acute, more or less 

 clasping, sometimes tapering at base, 1 to 3 inches long, 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.
