A poorly known species, in its described characters not clearly 

 distinguished from the earlier and variable E. glechonophyllum Less.,

 toothed, acuminate to an acutish tip, entire at base and cuneate- 

 attenuate at the insertion of the petiole, hispid with single hairs on 

 both surfaces, as much as 1 dm. long and 8 cm. wide; cymes axillary 

 and terminal, disposed in a panicle; peduncles pubescent, exceeding 

 the leaves; heads 4-6 mm. high, about 30-flowered; involucral scales 

 lance-linear, acute, hirtellous on the back; florets white; achenes
