1. (ENOTHfiRA, Evening Primrose. 



Herbs, stems usually erect: leaves alternate: flowers brightly colored, 

 regular, axillary or in terminal spikes: calyx-tube prolonged beyond ovary, 

 the 4 lobes usually reflexed, sometimes soon falling: petals 4: stamens 8: 

 stigma 4-lobed: capsule usually narrow and long, 4-celled, many-seeded. 



(E. biennis, Linn. Common evening primrose. Fig. 249. Stem erect 2 

 to 5 feet, hairy and leafy: leaves lance-oblong, somewhat repandly-toothed; 

 flowers pure yellow, fragrant, in terminal, leafy spikes, not remaining open 

 in broad sunshine: calyx-tube 2 to 3 times longer than ovary and lobes 

 reflexed: petals obcordate: pod oblong bluntly 4-angled. A very common 

 biennial of roadside and pasture, opening quickly at nightfall. 



(E. fruticosa, Linn. Sundrops. Biennial or perennial: stem erect, 1 to 

 3 ft., leafy, more or less hairy: flowers yellow, 1 to 2 in. in diameter, in 

 corymbed racemes, open in daytime: pod decidedly 4-angled and 4-ribbed, 

 rather downy, shortly stalked. Dry soil. 



(E. pvimila, Linn. Resembles preceding, but smaller, 5 to 12 inches high: 

 corolla yellow, about J^in. across: pod smooth, 4-angled, sessile or short 

 stalked. Dry soil. 



2. FtrCHSIA. Figs. 160, 189. 



Herbs or shrubby plants (some trees) : leaves opposite, or 3 in a whorl: 

 flowers drooping, axillary: calyx-tube colored, extended beyond ovary: 

 margin 4-lobed, spreading: petals4 on throat of calyx: stamens 8, projecting: 

 style long: fruit a 4-celled berry. A number of species of these ornamental 

 plants in cultivation. Mainly native to South America. 



r. Magelldnica, Lam. Smooth and tender: leaves simple, toothed, 

 slender-petioled : flowers hanging on long peduncles from leaf axils: calyx 

 red, lobes long, exceeding the tube and the petals: petals blue or purple or 

 red, obovate, notched, convolute about the bases of the long filaments and 

 style. The common window-garden fuchsias {F. speciosa) have descended 

 from this species, more or less hybridized with others. 



3. EPILOBIUM. Willow-herb. 



Mostly perennials, with leaves nearly sessile, alternate or opposite: 

 flowers white or puiple, spicate, racemed, or solitary: calyx-tube little
