men but clearly related although with slightly longer petioles. 
W UT LOCALITY: Triana, no. 1187 (K.). 
The type-specimen of E. caducisetum shows it to have 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. 
9. E. sotarense Hieron. Erect, herbaceous or suffruticose; 
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, nearly 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-lineat, 
2-3-ribbed, the outer dorsally covered 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.

Cauca: on the cone of the volcano Sotar4, alt. 4000 m., Stzibel, 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-b ’ 
branches ascending, when young hexagonal; leaves opposite, petiolate, 
deltoid, 3-3.5 cm. long, nearly as wide, coarsely crenate-dentate 
except at the acute apex and broad truncate or very shallowly sub- 
cordate base, short-acuminate at the insertion, 3-ribbed 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 t 
flowered, 6.5 mm. high, 6 mm. in diameter; involucre campanulate, 
3 mm. high; scales lance-linear, acute, subequal except 2-3 of i 
considerably reduced outermost, pulverulent; corollas (presumably
