Short entry again today, but that’s okay because there is little information about this species on the web. The San Francisco Botanical Garden provides the best information about Rojasianthe superba in cultivation (and this is where I photographed it in early April). Do note that it has no English common name. More photographs are available via Flickr: Rojasianthe superba, including some by frequent BPotD contributor Eric in SF@Flickr.
Native to the cloud forests of Guatemala and Chiapas, Mexico, you can read more about its native habitat and associated flora in Quedensley, TS and Bragg, TB. 2007. The Asteraceae of northwestern Pico Zunil, a cloud forest in western Guatemala. (PDF). Lundellia. 10:49-70.
