The numerous, narrow involucral bracts of fleabanes are typically about the same length, and are not overlapping as is found with the bracts of asters. Photographed at about 3400' along forest road #82 at the southeastern corner of Mt. Adams........July 17, 2005. The involucre of this species is lightly haired or glandular, while the stems below the inflorescence tend to be largely hair free.

The photo above shows a stem leaf of showy fleabane. The species gets its name from the 3 main nerves found in the blade of the leaf. The central vein is quite apparent, while the two lateral veins are fainter but visible all the same. Note also the ciliate leaf margins. This variety has longer, narrower stem leaves than those found in variety macranthus.
