Monsters, you have just made me order the Kew monograph. I had previously been subsisting on various papers and Tulips, Species and Hybrids for the Gardener, a generalist survey by Richard Wilford, who is at Kew, knows a lot about a lot of bulbs, contributed the cultivation chapter to the monograph and is a fine fellow. Last I saw, the AGS had it on sale. Nice illustrations, too. Many species reduced to synonymy. Bob Nold Denver, Colorado, USA
