slightly viscid-vernicose on the younger parts and _ inflorescence; 
branches ascending or erect, at first somewhat quadrangular, leafy; 
leaves opposite, petiolate, elliptical, obtuse, rounded at the base, 
crenulate, coriaceous, green and lucid above, slightly paler and some- 
what lucid beneath, 2.5-5(-8) em. long, about half as wide, pinnately 
veined from base to apex, the veins diverging at a wide angle from the 
midrib, veinlets reticulated and prominulent on both surfaces; corymb 
strongly convex, 5-7 cm. in diameter, many-headed, fastigiately 
branched, dense; heads 6—7-flowered, about 7-8 mm. high; involucre 
narrowly campanulate; scales 8-10, oblong, obtuse, thickish, obscurely 
ribbed, essentially glabrous but viscid; corollas about 5 mm. long; 
proper tube slender, 1-1.5 mm. long, granulated; throat subcylindric, 
3.5-4 mm. long, glabrous; achenes (immature) viscidulous; pappus- 
bristles yellowish-white, stiffish, unequal, the longest about 4 mm. in 
length — Abh. Naturw. Ges. Halle, xv. 324 (1882), in advance re-

(Berl., fragm. Gr.).] This form with elliptical crenately toothed 
leaves, typical of Klatt’s species and of Hieronymus’s var. crenata, 
does not thus far appear to have been found in Ecuador. Hieronymus 
is probably right in classing it and two or three other leaf-forms as 
varieties of the same species, but seems to have overlooked the prior 
description of the Mathews plant by Klatt, which necessarily becomes 
the type of the species, to which the Ecuadorian plant may be ap- 
pended as a variety, thus:
