Meet the Authors
Authors from left to right: Dave Palzkill, Gene Joseph and Mark Dimmitt
Mark A. Dimmitt has a Ph.D. in biology (zoology-herpetology) from the University of California at Riverside. He is retired from a 40-year career as a botanist/ecologist, mostly at the Arizona-Sonora Desert Museum. His second career is collecting and hybridizing plants, first Trichocereus (cacti) and Tillandsia (bromeliads). Since the late 1970s his main focus has been on breeding Adeniums.
David A. Palzkill has a Ph.D. in Horticulture and Plant Pathology from the University of Wisconsin at Madison where he studied calcium-related problems of vegetable
crops. Following fourteen years on the faculty of the University of Arizona, he consulted on alternative crops for dry regions and grew adeniums commercially for about 20 years.
Gene E. Joseph studied Plant Sciences at the University of Arizona in Tucson. He was plant propagator at the Arizona-Sonora Desert Museum where he focused his
interest in desert flora. He has run Plants for the Southwest, a desert plant nursery in Tucson, since 1986

Page 96, Origin of 'Singapore': I rediscovered a lost note from Albert Chan and a letter from Frank Horwood dated 1980. Professor Holttum told Horwood that Adenium 'Singapore' was introduced to horticulture in Singapore in 1933, 50 years earlier than I had thought. (Richard Eric Holttum was Director of the Singapore Botanical Garden from 1926 to 1949, and later was on the staff of the Royal Botanical Gardens at Kew.) Chan's and Horwood's letters are archived here.
Page 106, third paragraph: In fact, A. swazicum and A. oleifolium do experience freezing temperatures. Adenium oleifolium remains a short shrub partly because it is periodically frozen to the ground.
Page 127, Figure 38: Photo: P. Mukundan, not Nathan Wong.
Page 134: The Adenium "arabicum" at the bottom of the page is by Godong Ijo Nursery, not David Clulow.
Page 32: As stated, A. "arabicum" does indeed tend to grow short and squat at low, dry elevations and high, cold ones, and is often arborescent in wetter habitats. However, growth form is not only environmentally controlled; there is also a strong genetic influence. In cultivation some seedlings become shrubs with squat caudexes, while others grown in the same conditions become trees with tall, conical trunks.
Page 47: The range of the unnamed Omani Adenium (A. dhofarense as of 2015) extends into eastern Yemen, near Hvai (Boris Vrskovy pers. comm.). The plants in Figures 108 and 109 are in fact from this location in Yemen, not in Oman as the caption states. The photos are also by Boris.
Page 54: An adenium registry should go online soon. Stay tuned. (It never happened as of 2023)
Hybrid Chapter, page 70: After some discussion with Thai growers, it is apparent that most of their "arabicum" cultivars are in fact not cultivars. That is, their named plants such as 'Golden Crown', 'Petch Ban Na', Ra Chi Nee Pan Dok', etc. will not breed true either from seed or asexual means. This is because the names refer to particular growth forms achieved by careful pruning and training of the plants from a very small size. It is still unclear whether there is a formal nomenclatural term for this kind of plant. But they should not be called cultivars, and their names should not be enclosed in single quotes.
