314 ROBINSON. 



side, Quetame, alt. 1300-1500 m., Pennell, no. 1871 (Gr.), a doubtful speci- 

 men but clearly related although with slightly longer petioles. 

 Without locality: Triana, no. 1187 (K.). 



The tjype-specimen of E. caducisetum shows it to ha\e been a some- 

 what more loosely grown individual than the type of E. epilobioides, 

 but the differences, notably in the length of the internodes and petioles, 

 are completely bridged by intermediates now at hand, and are of a 

 kind permitting no clear or natural distinction. 



69. E. sotarense Hieron. Erect, herbaceous or suifruticose; 

 stem terete, somewhat glandular-pubescent ; leaves opposite or ternate, 

 ovate, acuminate, rounded at the base, 2.5-3 cm. long, 2 cm. wide, 

 crenate-serrate, nearl}' glabrous except for a scattered pubescence on 

 the nerves, 3-nerved from the base, the lateral nerves forking ; branches 

 of the inflorescence and pedicels closely beset with dark divaricately 

 spreading gland-tipped hairs; pedicels 3-5 mm. long; heads about 

 30-flowered, 7 mm. high; involucral scales about 18, lance-linear, 

 2-3-ribbed, the outer dorsally coxered with dark purplish-brown more 

 or less glandular tomentum, acute; corollas about 4 mm. long, with 

 slender proper tube slightly exceeded by the cylindric-campanulate 

 throat; achenes at maturity black, 2.5 mm. long, slightly tapering 

 at both ends. — Hieron. in Engl. Bot. Jahrb. xxviii. 574 (1901). E. 

 soraicnse Hieron. 1. c. xxi. 333 (1895), not Ivlatt. 



Cauca: on the cone of the volcano Sotara, alt. 4000 m., Slilbel, no. 329b 

 (Berl., fragm. Gr.). 



Obviously near E. gracile, but to be distinguished by the more 

 copious and gland-tipped pubescence on the inflorescence. 



70. E. intercostulatum Robinson. Shrub, very finely grayish- 

 puberulent, not glandular; stems subterete, costate, grayish-buff; 

 branches ascending, when young hexagonal; leaves opposite, pctiolate, 

 deltoid, 3-3.5 cm. long, nearly as wide, coarsel\- crenate-dentate 

 except at the acute apex and broad truncate or Aery shallowly sub- 

 cordate base, short-acuminate at the insertion, 3-ribbcd from the base, 

 sparingly pulverulent-puberulent on both surfaces, scarcely paler 

 beneath, membranaceous; petiole about 1 cm. long; corymbs dense, 

 round-topped, many-headed, terminal and single or supplemented by 

 smaller corymbs from the upper axils; heads pedicellate, about 15- 

 flowered, 6.5 mm. high, 6 mm. in diameter; involucre campanulate, 

 3 mm. high; scales lance-linear, acute, subequal except 2-3 of the 

 considerably reduced outermost, puherulent; corollas (presumably
