_ Persistent search has failed to disclose between the following varie- 
ules any constant or natural differences which would justify their 
maintenance as separate species. 
Var. typicum. Stem, branches, pedicels, and often outer involu- 
cral scales, as well as the margins, nerves, and rarely the surface of the 
leaves finely pubescent, the hairs delicate, short, dark, purplish or 
gag ascending or somewhat spreading.— Lit. and exsicc. as 
above. 
Here, provisionally and somewhat doubtfully, may be placed. E. 
sotarense, var. breviflora Hieron. in Engl. Bot. Jahrb. xxviii. 574 (1901), 
wn as yet only from the original material from open thickets on 
the slopes of Mt. Guélcala in the district of Tuquerres, alt. 2500-2900 
m., Lehmann, no. 5195 (Berl., fragm. Gr.). Although the heads 
are slightly smaller than usual in the species and the leaves a trifle 
ger and more pubescent, these differences are of degree rather than 
kind, and are no greater than are usually bridged by complete inter- 
stadation. The pubescence of the pedicels, while more copious, is 
Precisely of the sort prevalent in E. gracile, and not gland-tipped as 
Mm the typical E. sotarense. 
Var. epilobioides (HBK.) Robinson, comb. nov. Glabrous 
lout or with only minute vestiges of pubescence on the branches 
inflorescence.— FE. epilobioides HBK. Nov. Gen. et Spec. iv. 
125 (1820). E. caducisetum DC. Prod. v. 165 (1836). 
Cunpivamarca: in temperate region near Guaduas, Humboldt & Bonpland 
(Par., phot. Gr.); about Santa Fé de Bogota, [specimen from herb. of] Deles- 
pos (DC., phot. Gr.); at the falls of Tequendama, 8-11 Dec. 1852, Holton 
a N. Y.); near Bogoté, in mountains, 18 Nov. 1852, Holton (N. Y.); near
