99. Eupatorium campylocladum Robinson, Proc. Bost. Soc. Nat. Hist. 31: 

 247. 1904. 



Coahuila; type from General Cepida. 



Pliant-stemmed shrulj with dark gray cortex; branches flexuous, nodulose (the 

 internodes mostlj' verj^ short), denuded of leaves except near the tip; leaves 

 ovate-suborbicular, obtuse, serrate, shallowly cordate at base, about 2 cm. long 

 and 1.7 cm. wide, glabrous but gummy on both surfaces; petiole 5 to 7 mm. long; 

 heads 1 to several at tips of branches, about 13 mm. long; phyllaries oblong, 

 acute, thin, green, glandular-puberulent. 



100. Eupatorium vernicosum Schultz Bip.; Greenm. Zoe 5: 186. 1904. 

 Mexico; type (i. e., plant described by Greenman) from rocks near timber line 



on Mount Ixtaccihuatl. 



Low shrub with forking nodulose blackish stems and branches; leaves oppo- 

 site, ovate, shortly acuminate, serrate, rounded to shallowly cordate at base, 

 gummy and very viscid on both surfaces, chartaceous or subcoriaceous, 3 to 6 

 cm. long, 1.5 to 4 cm. wide; heads mostly 1 to 5 at the ends of the branches, 

 1.5 cm. long and equally broad, long-pediceled. 



101. Eupatorium multiserratum Schultz Bip. in Seem. Bot. Voy. Herald 

 301. 1856. 



Type locality vaguely stated as Sierra Madre, but species rediscovered by 

 Dr. Palmer in Durango. 



Tall shrub with terete stems, long internodes, and ascending branches; leaves 

 opposite, ovate to ovate-oblong, acute to obtuse at tip, sharply serrulate, rounded 

 at base, thickish-membranaceous, tufted in the axils of the chief veins beneath, 

 3.5 to 5.5 cm. long, 1.8 to 2.7 cm. wide; petiole 1 to 1.3 cm. long; corymbs loose, 

 few-headed, umbelliform; heads 1 to 1.2 cm. long, about 32-fiowered; phyllaries 

 smoothish, lance-linear, attenuate, nearly equaling the florets. 



102. Eupatorium hyssopinum A. Gray, Proc. Amer. Acad. 15: 28. 1879. 

 Eupatorium koelliaefoliutn Greene, Pittonia 3: 31. 1896. 



Kyrstenia koelliaefolia Greene, Leaflets 1 : 9. 1903. 



San Luis Potosf, Durango, and Chihuahua; type probably from the region of 

 San Luis Potosi. 



Erect-stemmed, essentially herbaceous perennial but sometimes developing a 

 decidedly woody base in age; stems terete, 30 to 60 cm. high, bearing almost 

 from base to summit many slender ascending branches; leaves lanceolate, acute 

 or obtuse at apex, cuneate at the sessile base, ciliolate, otherwise nearly glabrous, 

 12 to 22 mm. long, 3 to 6 mm. wide, membranaceous; corymbs terminal, moder- 

 ately convex, 6 to 14 cm. in diameter; corollas white. 



103. Eupatorium riparium Kegel, Gartenflora 1866: 324. 1866. 

 Eupatorium flexicaule Schnittspahn, Zeitschr. Gartenb. Ver. Darmstadt 6: 



Anlage 2: 5. 1857, without diagnosis. 



Eupatorium riparium Schultz Bip.; Schnittspahn, loc. cit. 1857, also without 

 diagnosis. 



Eupatorium harrisii Urban, Sj'mb. Antill. 1: 460. 1900. 



Slender, nearly herbaceous plant with terete, flexuous, finely pubescent, at 

 length somewhat Ugnescent stems; leaves opposite, lanceolate, attenuate to each 

 end, serrate from near the middle outward, 3-nerved from somewhat above the 

 base, 5 to 10 cm. long, 1 to 2.5 cm. wide, sparingly pubescent on the nerves; 

 corymbs numerous, small, panicled; phyllaries pale green, lanceolate, scarious- 

 edged; corollas white. 



A copious bloomer, easily grown and long valued in hothouse cultivation. In 

 giving this species its first valid publication, Regel in no way alludes to its earlier 

 though invalid mention in print, which therefore does not give ground for use of 

 Schultz 's name as authoritj".
