2 EPILOBIUM L. Gen. n. 471. 



Perennial or annual herbs, with nearly sessile, denticulate or en- 

 tire, often fascicled leaves, and rose-colored, purple or white, very 

 rarely yellow, flowers in panicles or racemes. Tube of the calyx 

 not conspicuously prolonged beyond the ovary ; the limb deeply 

 4-cleft ; campanulate or funnel-form or 4-parted to the base, the 

 lobes spreading deciduous. Petals 4, spreading or somewhat 

 erect. Stamens 8 the 4 alternate ones shorter; anthers ellipti- 

 cal or roundish, fixed near the middle. Stigma oblong, clavate 

 or with four spreading or revolute lobes ; capsule linear, 4-sided, 

 4-celled, 4-valved. Seeds numerous, ascending, the summit fur- 

 nished with a coma or tuft of long hairs. 



1. CHAM^NERION. Calyx cleft almost to the ovary. Cor- 

 olla slightly irregular. Petals widely expanded. Stamens in- 

 serted in a single series ; the filaments dilated below. Style at 

 first recurved. Stigma with four ultimately divergent lobes. 

 Capsule mostly linear-fusiform, many-seeded. Seeds fusiform, 

 beakless, not papillate in one species. Cespitose perennials 

 from a stout caudex, bearing sessile scaly winter buds with terete 

 stems and ample leaves. 



E. spirillum Lam. Fl. France 1077. Sterna "erect, 2-6 feet high, sub- 

 simple, glabrate below: leaves lanceolate, acute, nearly entire, 4-8 inches 

 long, on very short petioles, thin pinnately veined, with the evident lateral 

 veins confluent in submarginal loops : infloresence elongated ; racemes 

 with small bracts ; young flower buds soon reflexed, but again spreading 

 or ascending before expansion : petals 5-7 lines long, style exceeding the 

 stamens, hairy at base; capsule 2-3 inches long; seeds less than a line 

 long, with very long dingy coma. Alaska to California, the Eastern States, 

 Europe and Asia. 



E. latifolium. L. sp. 347. A span to afoot or more high, frequently 

 branched, mostly glabrate below ; leaves 1-2 inches long ; usually oppo- 

 site and connected below on the branches and rarely on the main stem ; 

 lanceolate to ovate, acute at both ends, entire or sparingly and minutely 

 denticulate, scarcely petioled, rather coriaceous, the mostly free lateral 

 veins inconspicuous: inflorescence usually short and few-flowered, leafy 

 throughout, the buds not reflexed; petals 8-15 lines long, rather narrow, 

 styles shorter than the stamens, glabrous; seeds a line long or more. 

 Damp places Arctic America to N. E. Oregon and N. E. states, Asia and 

 the Himalayas. 



2. LYSIMACHION. Calyx with an evident though usually 

 short tube mostly somewhat hairy within. Corolla regular, the 

 petals deeply notched or obcordate ; usually not expanding be- 

 yond funnelform. Stamens inserted in two more or less dis- 

 tinct whorls ; those opposite the sepals longer and more deeply 

 inserted. Style not declined mostly glabrous. 



* Stigma 4-cleft: seeds beakless. Perennials with rather slender 

 caudex and usually terete stems.
