Notes

An attractive alpine species reaching the highest elevations in the genus in New Guinea. It is usually more condensed in habit than E. hooglandii and differs at once from that species in the glabrous ridge decurrent from the center of each petiole and the elevated pubescent lines decurrent from the edges of the petiole. It grows sympatrically with E. hooglandii and E. keysseri, but no intermediates have been observed; intermediates with the former species would be very difficult to detect.
