ISI 2004-26.  Haworthia maxima.  Bruce Bayer notes that I followed his and E. van Jaarsveld’s treatment of this species in the Monocotyledon volume of the Illustrated Handbook of Succulent Plants (apparently penned before 1999 but not published until 2001), which is superseded by his more thorough treatment in Haworthia Revisited (1999), in which he makes the case in favor of the name H. pumila (L.) M.B. Bayer over the synonym H. maxima (Haw.) Duval. ISI 2003-32.  Kalanchoe ‘Hybrid’, variegated.  According to Steve Jankalski, this is a variegated sport of Kalanchoe daigremontiana × K. delagoensis, a cross made by A. Houghton and listed in one of Johnson’s catalogs as K. ‘Houghton’s Hybrid’.  Jankalski has suggested a name, published here, for the variegated sport distributed as ISI 2003-32: Kalanchoe ‘Pink Sparkler’. ISI 2005-6.  Agave ‘Blue Flame’.  Brian Kemble notes that my assertion is somewhat exaggerated that this is the first recorded hybrid between subgenera Agave and Littaea.  Of course, I failed to recall the long-cultivated natural hybrid of A. victoria-reginae (Littaea) and A. scabra (Agave), the so-called “shark-skin agave”.  Further, he notes that if one accepts the inclusion of Manfreda in Agave (based on fairly convincing molecular evidence though not yet widely adopted by collectors), there are three subgenera of Agave, not just two.  Hybrids between subgenera Manfreda and Agave are also realized in Agave ‘Macho Mocha’, recently introduced by Yucca Do Nursery, among others, and apparently a hybrid between a manfreda and A. celsii (Littaea).  We also grow an apparent hybrid of A. polianthiflora (Agave) and A. longiflora (Manfreda) that may merit future ISI introduction. ISI 2005-36.  Sansevieria downsii.  Steve Jankalski correctly points out that the illustration compares S. downsii with the smaller S. ballyi (only recently published by Len Newton, Brit. Cact. Succ. J. 22:10-12, 2004), not S. suffruticosa as stated.  He also questioned whether the larger plant in the photo is indeed S. downsii.  We discovered that while growing under lush conditions our plants at first have silvery bands and only turn the solid, dark green considered characteristic of this species in age.
