Hypericum. HYPERICACE^. 287 



c. Sepals small : flowers small, in naked cymes : leaves rather broad, thin, and veiny : some- 

 what shrubby at base, a foot or two high, simple or branching. 



H. adpressum, Bakton. Leaves linear-lanceolate to narrowly oblono-, mostlv acute 

 usually ascending, about 2 inches long, 3 to 4 Hues broad, revolute, pellucid-punctate witli- 

 out black dots, translucently veiny : cymes leafy only at base, dichotomal flowers mostly 

 very short-pedicelled : sepals linear to lanceolate, acute, ^ to J as long as the petals, often 

 reflexed : capsule ovate to oblong, about 2 lines long; seeds oblong. — Fl. Philad. ii. 1.5-

 Ell. Sk. ii. 31 ; Torr. & Gray, 1. c. 166. H. adpressum, ^ar. fastigiatum, Torr. & Gray, 1. c. 

 673. — Moist ground, Massachusetts to New Jersey, Pennsylvania, and Georgia. 



H. nudiflorum, Michx. Leaves thinner, ovate-lanceolate or oblong, obtuse, 2 to 3 inches 

 long, \ inch broad, pellucid-punctate and with very small crowded black dots : cymes pedun- 

 culate, naked at base, loosely flowered, dichotomal flowers pedicelled : sepals variable, linear 

 to oblong, about | as long as the petals : capsule ovate-conical, about 3 lines long ; seeds 

 cylindrical, with prominent rhaphe. — Michx. in Willd. Spec. iii. 1456 ; Torr. & Gray, 1. c. 

 162. //. m<//b/»nn. Coulter, Bot. Gaz. xi. 86, not Lam. — From North Carolina through 

 the Gulf States to Texas. The more naked cymes, and the broader leaves with their very 

 numerous and crowded black dots, serve to distinguish this species easily from the last. 



= = Placentae projecting a little, or not at all : sepals unequal. 



a. Leaves mostly linear, with rather large and scattered pellucid dots : flowers in somewhat 

 leafy-bracted cymes : capsule conical or globose ; seeds large^ oval, strongly rugose 

 transversely. 



H. cistifolium, Lam. Simple or branched, 1 to 3 feet high : leaves linear to narrowly 

 oblong, mostly obtuse, 2 to 3 inches long, 3 to 6 lines wide : cyme loosely flowered, dichot- 

 omal flower mostly sessile : sepals varying from small and linear to ovate and as long as 

 the petals : capsule from depressed-globose to ovoid, about 2 lines long ; seeds with rhaphe 

 almost winged. — Diet. iv. 158, not Coulter, Bot. Gaz. xi. 86. H. rosmarinifolium, Lam. 1. c. 

 159, not Torr. & Gray, Fl. i. 159. H. spkcerocarpum, Michx. Fl. ii. 78 ; Torr. & Gray, 1. c. 163 

 (sphcerocarpon) ; Coulter, 1. c. 87. — Rocky banks of the Ohio and its tributaries, southward 

 to Arkansas and Alabama. The large and rough seeds are the most characteristic ones of 

 the genus, and serve to distinguish the species readily from any others likely to be con- 

 founded with it. 



H. dolabriforme, Vent. Low, straggling, | to 1| feet high : leaves linear (rarely nar- 

 rowly oblong-linear), widely spreading, an inch or less long, 1 to 2 lines broad, mostly acute: 

 cyme usually few-flowered, dichotomal flower pedicelled : sepals large and foliaceous, lanceo- 

 late to ovate, acute or acuminate, as long as the petals : capsule ovate-conical, coriaceous, 

 almost triquetrous, about 3 lines long. — Hort. Cels. t. 45 ; Pursh, 1. c. 378 ; Chois. 1. c. 547 ; 

 Torr. & Gray, Fl. i. 162. H. procumhens, Desf. in Willd. Spec. iii. 1450; Michx. Fl. ii. 81 ; 

 Pursh, 1. c. 379 ; Chois. 1. c. — Dry sterile hills, Kentucky, Tennessee, and Missouri. 



b. Leaves oblong, obtuse : flowers in nearly naked cymes : capsule ovate ; seeds oblong, 

 minutely striate and pitted. 



H. opacum, Torr. & Gray. One to four feet high : leaves linear-oblong, about 1 inch 

 long and 2 to 4 lines wide, closely sessile, pellucid-punctate with minute crowded dots, often 

 rusty beneath : flowers 3 to 5 lines broad, in divaricate cymes, the dichotomal flowers mostly 

 sessile : sepals oblong to obovate, about half as long as the bright yellow petals : capsule 2 

 to 3 lines long. — Fl. i. 163. //. punctulosum, Bertol. Misc. Bot. xiii. 18, t. 3, f. 2. //. cisti- 

 folium, Torr. & Gray, 1. c. 674, not Lam. — South Carolina and Georgia to Florida and 

 Mississippi. 



H. ellipticum, Hook. Mostly herbaceous, 10 to 20 inches high: leaves elliptical-oblong, 

 sessile or tapering at base, ^ to 1| inches long, 3 to 5 lines broad, pellucid-punctate with 

 large scattered dots, translucently veiny : flowers 4 to 6 lines broad, occasionally 4-merous, 

 in few-flowered cymes, the dichotomal flowers pedicelled : sepals mostly foliaceous and spread- 

 ing, oblanceolate to narrowly obovate, usually shorter tlian the pale yellow petals : capsule 

 as in the last. — Fl. Bor.-Am. i. 110; Torr. & Gray, Fl. i. 164. U. sj>/i(£rocarpum. Barton,
