This member of the Ericaceae family was described by Martin Martens and Henri Guillaume Galeotti in 1842. It's found in the trees as a epiphyte in the cloud forests of southern Mexico to Costa Rica and Guatemala. Lots of water and some sun. The tube-like caudex will grow to 20 centimetres in diameter, the stems one to four meters. The flowers are pink, and seeds are the only way of reproducing.
The genera name after John Maclean, 19th century Scottish merchant who exported plants from Lima, Peru. The species name from Latin insignis, meaning 'remarkable' or 'out standing' for the flowers.
