slightly viscid-veniicosc 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) cm. 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—1 mm. long, glabrotis; achenes (immature) viscidulous; pappus- 

 bristles yellowish-white, stiffish, unequal, the longest about 4 mm. in

 locality or number, Mathews (fragm. Gr.); Cutero, von Jelski, no. 789 

 (Berk, 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: 



Var. pseudofastigiatum (Hieron.), comb. nov. Leaves ovate- 

 lanceolate, acute or acutish at the apex, rather sharply serrate-dentate 

 from somewhat below the middle, entire and decidedly cuneate at the 

 base; leaf -texture and venation, as well as inflorescence and floral 

 characters, as in the typical variety. — E. fastigiatum ? Benth. PI.

32. E. DENDROIDES (HBK.) Spreng. Tree with glabrous at first 

 somewhat angled soon subterete dark-purple branches; leaves oppo- 

 site, petiolate, ovate-oblong, narrowed or somewhat acuminate to a 

 mostly obtusish and slightly cuspidate tip, crenate or cuspidate-
