FF. fls. yelloivish or ivhitish. 



9. Hamiltonianus, Wall. (E. Maackii, Rupr.). Shrub, 

 rarely small tree, to HO ft., with almost terete branches: 

 Ivs. elliptic to ovate-lanceolate, acuminate, serrulate, 

 2-5 in. long: fls. in 3-12-fld. cymes: capsule deeply 4- 

 lobed, with rounded valves, pink (yellowish in the 

 Himalayan form); seed usually not wholly covered by 

 the aril, grayish brown. June. Himalaya to Manchuria. 

 Var. semipersistens, Rehder (E. Sieboldidnus, Hort., 

 not Blume). Lvs. elliptic, long-acuminate, half ever- 

 green, keeping its bright green foliage South until mid- 

 winter: fr. bright pink, ripening very late. 



10. Sieboldianus, Blume (E. Yeddoensis, Hort.). 

 Shrub or small tree, to 25 ft. : Ivs. ovate-elliptic or ellip- 

 tic, crenately serrate, shortly and abruptly acuminate, 

 usually, puberulous on the veins beneath when young : 

 Ivs. 3-6 in. long, 1-2% in. broad : cymes 5-20-fld. : cap- 

 sule pink, slightly lobed and 4-angled, with 4 narrow, 

 thick wings; seed scarlet. June. Jap. This species is 

 often confounded with the former, but easily dis- 

 tinguished by its larger and much broader Ivs. 



11. Bungeanus, Maxim. Shrub, to 15ft., with slender 

 branches: Ivs. slender-petioled, ovate-elliptic or ellip- 

 tic-lanceolate, long-acuminate, finely serrate, 2-4 in.

 deeply 4-lobed and 4-angled, yellowish : seeds white or 

 pinkish, with orange aril. June. China, Manchuria, 

 M.D.G. 1899:569. Very attractive with its rather large, 

 profusely produced frs., remaining a long time on the 

 branches. 



AA. Foliage evergreen. 



12. Jap6nicus, Linn. Upright shrub, to 8 ft., with 

 smooth and slightly quadrangular or striped branches : 

 Ivs. obovate to narrow-elliptic, cuneate at the base, acute 

 or obtuse, obtusely serrate, shining above, l%-2% in. 

 long : fls. greenish white, 4-merous, in slender-pedun- 

 cled, 5- to many-fld. cymes: capsule depressed, globose, 

 smooth, pink. June, July. S. Jap. A very variable 

 species. Var. macrophyllus, Sieb. ( var. robusttis, Hort. ) . 

 Lvs. oval, large, 2^-3 in. long. Var. microphyllus, 

 Sieb. (E. pulchellus, Hort. Eurya microphylla, Hort. ). 

 Lvs. small, narrow-oblong or oblong-lanceolate. Var. 

 columnaris, Carr. ( var. pyramiddlis, Hort. ) . Of upright, 

 columnar habit: Ivs. broadly oval. There are many va- 

 rieties with variegated Ivs.; some of the best are the 

 following: Var. arg6iiteo-variegatus, Rgl. Lvs. edged 

 and marked white. Var. aureo-variegatus, Rgl. Lvs. 

 blotched yellow. Var. dlbo-marginatus, Hort. Lvs. 

 with white, rather narrow margins. Var. medio-pictus, 

 Hort. Lvs. with a yellow blotch in the middle. Var. 

 pallens, Carr. (var. flavescens, Hort.). Lvs. pale yellow 

 when young; similar is var. aureus, Hort., but the yel 

 low is brighter and changes quicker to green. Var. 

 viridi-variegatus, Hort. (var. Due d'Anjou, Hort.). 

 Lvs. large, bright green, variegated with yellow and 

 green in the middle. 



13. radicans, Sieb. (E. Japonicus, var radlcans, 

 Rgl.). Low, procumbent shrub, with often trailing and 

 rooting or climbing branches, climbing sometimes to 20 

 ft. high: branches terete, densely and minutely warty: 

 Ivs. roundish to elliptic-oval, rounded or narrowed at 

 the base, crenately serrate, usually dull green above, 

 with whitish veins, %-2 in. long: fl. and fr. similar to 

 the former, but fr. generally of paler color. June, July. 

 N. and M.Jap. R.H. 1885, p. 295. G.C. 11.20:793.- 

 Closely allied to the former, and considered by most 

 botanists as a variety; also very variable. Var. Carrier!, 

 Vauv. Low shrub, with ascending and spreading 

 branches: Ivs. oblong-elliptic, about IK in. long, some- 

 what shining. Var. argenteo-marginatus, Hort. Lvs. 

 bordered white. Var. rdseo-marginatus, Hort. Lvs. 

 bordered pinkish. Var. reticulatus, Rgl. (var. pictus, 

 Hort., var. argenteo-variegatus, Hort.). Lvs. marked 

 white along the veins. 



E. echindtus, Wall. Usually creeping or climbing, with root- 

 ing branches: Ivs. ovate-lanceolate: fr. spiny. Himal. B.M. 

 2767. E. fimbridtus, Hort., not Wall.=pendulus. E. grandi- 

 flbrus. Wall. Shrub, to 12ft.: Ivs. obovate or obovate-oblong, 

 finely and acutely serrate : fls. white, four-fifths of an in. across : 

 fr. globose, yellow. Himal. E. occidentdlis , Nutt. Shrub, to

EUPATOEIUM (from an ancient personal name). 

 Compdsitce. More than 400 species, mostly of warm or 

 tropical countries, herbs or shrubs. Heads discoid (ray- 

 less), the florets 3 to many, perfect: involucre cylindrical, 

 bell-shaped or hemispherical, the imbricated bracts in 

 2 or more series : receptacle flat or conical, naked : co- 

 rolla regular, 5-toothed, slender-tubed: akenes5-angled, 

 truncate : pappus a single row of hair-like, scabrous 

 bristles: perennials. 



Gardeners know two classes of Eupatoriums, the glass- 

 house and the hardy kinds. The latter are native spe- 

 cies which only lately have been introduced to the trade 

 as border plants. The glasshouse species are seen only 

 in the larger or amateur collections, as a rule, although 

 some of them are old garden plants. They are confused 

 as to kinds. These species demand the general treat- 

 ment of Piqueria (or Stevia), a cool or intermediate 

 temperature and pot culture. They are easy to grow. 

 Prop, readily by cuttings. They are useful for winter 

 bloom. Of all Eupatoriums the individual heads arc 

 small, but they are aggregated into showy masses. FOJ
