10. E. ARBOREUM HBK. A small tree in technical characters 

 exceedingly close to the preceding; branches also hexagonal and 

 smooth, those of the inflorescence sordid-pubescent; leaves much as 

 in the preceding but in the type-material really rounded at base, 

 densely sordid-pubescent beneath; corymbs rounded, about equalling 

 or slightly exceeding the leaves; heads about 25-flowered; involucre 

 somewhat turbinate-campanulate; scales fuscous-stramineous, ciliate 

 and dorsally somewhat puberulent or pulverulent, inclining to vis-

 Gen. et Spec. iv. 131 (1820); Jameson, Syn. PI. Aeq. ii. 87 (1865); 

 Hieron. in Engl. Bot. Jahrb. xxix. 10 (1900), excl. syn. E. buddlcae-

 on slopes of Chimborazo, Sodiro, no. 6/16, ace. to Hieron. 1. c. —

 The Peruvian E. discolor DC. Prod. v. 161 (1836), reduced by Hier- 

 onymus, 1. c, to this species, is shown by the original in the Prodromus 

 Herbarium at Geneva to have leaves cuneate at base, much less 

 toothed (indeed only obsoletel}' crenulate), and much more densely 

 and copiously white-tomentose beneath. 



11. E. SALViAEFOLiUM HBK. A climbing shrub with terete 

 shallowly furrowed sticky branches; leaves opposite, deflexed, oblong- 

 lanceolate, gradually acuminate, rounded at base, deeply crenulate- 

 denticulate (some of the teeth triangular and rather sharp, others 

 ovate-oblong and rounded at the tip), coriaceous, glabrous and green 

 but bullate-rugose above, white-tomentose beneath, 7-8 cm. long, 

 1-2.5 cm. wide; petiole about 1 cm. long; corymb terminal, rounded; 

 heads glomerulate; involucre and florets as in the two preceding 

 species. — Nov. Gen. et Spec. iv. 131 (1820); Jameson, Syn. PI. Aeq. 

 ii. 88 (1865). — Chimborazo: in cool places on slopes of Chimborazo,
