    On the cover: Arrojadoa eriocaulis is one of the bizarre and beautiful members a section of the genus featured in this month’s cover feature by Brazilian cactus expert Pierre Braun. Beautiful hummingbird-pollinated flowers are formed from a cephalium at the top of a thin stem, which itself emerges form a single, large, underground tuber. Each year normal stem growth resumes to leave fuzzy skirts along the stem that indicate its age. After three or four seasons of growth the stem will senesce and be replaced. While not particularly common in collections, cultivation is easy; if the stems are grafted they can grow a meter or more long.
