72a. E. DoMBEYANUM DC. Prod. v. 167 (1836). It seems by no 

 means improbable that this species (discussed in some detail on page 

 11) was originally collected in Peru. It reached DeCandolle devoid 

 of data beyond the fact that it had been gathered in South America 

 by Dombey (DC, phot. Gr.), whose explorations were chiefly in 

 Peru. 



73. E. GiLBERTii Robinson (p. 16). Slender and nearly glabrous 

 perennial herb, or perhaps shrub; stems greenish straw-colored, round, 

 about 2 mm. thick, flexuous, at maturity entirely glabrous, when 

 young sparingly provided with an inconspicuous pubescence of minute 

 straightish non-glandular hairs; these becoming somewhat more 

 abundant on the inflorescence; leaves opposite, ovate, acute or slightly 

 acuminate, mucronulate-serrate or -crenate (the teeth inconspicu- 

 ous, about 0.6 mm. high and 5 mm. apart), thin, membranaceous, 

 above green and puberulent on the nerves, beneath somewhat paler 

 and glabrous, 6-7 cm. long, 3-3.5 cm. wide, 3(-5)-nerved essentially 

 from the rounded or subcordate entire base; petiole slender, about 

 1.7 cm. long, puberulent above; corymbs compound, flattish, rather 

 loose; pedicels 4-10 mm. long; heads small, scarcely 5 mm. high or 

 thick, about 26-flowered; scales of the campanulate involucre about 

 17, nearly equal, oblong-lanceolate, greenish-stramineous, acutish, 

 scarious-margined, ciliate, sparingly pubescent on the back; corollas 

 white, about 3.3 mm. long, the proper tube glabrous, about equalling 

 the campanulate throat, limb hispidulous; achenes (very immature) 

 1.2 mm. long, apparently glabrous; pappus-bristles about 20, white. —

 Robinson, Proc. Am. Acad. liv. 362 (1918). E. Sternbergiatium Ball 

 Jour. Linn. Soc. xxii. 43 (1885), as to plant first mentioned. — Lima 

 in the middle region of the Andes in the upper valley of the Rimac 

 River, alt. 1830-3355 m., April, Ball (Gr.). Ball, 1. c, remarks that 

 the plant grows to a height of several feet. [Ecuador.] 



75. E. SCOPULORUM Wedd. Fruticulose, much branched, 2-5 

 dm. high; stems terete, slender, often decumbent, dark, nodose below 

 after the early fall of the leaves; lower internodes 5-10 mm., the 

 upper often 3-5 cm. long; leaves ovate, acute, rounded or subcordate 

 at base, crenate-serrate (teeth about 5 on each side), membranaceous, 

 3-nerved from the base, slightly puberulent on the nerves, 8-18 mm. 

 long, 5-12 mm. wide, scarcely paler beneath; petiole slender, 3-6 mm. 

 long; corymbs terminal, simple and 3-5-headed or compound and
