The following list follows the order in which specimens should be housed in the Compton Herbarium, National Botanical Institute, Kirstenbosch. This list has a few amendments to that published in Haworthia Update 2 ca2006. Gordon Rowley published a list of cultivar names in Alsterworthia to more formally recognise so many names that are useful or informative to collectors. The object of classification is really to synthesise and generalise about plants. As Dr Eggli stated, he feels he can attach little weight to any classification except in terms of the understanding he gains for the plants he has seen and knows. So this list of mine is the product of my understanding of the plants I have seen and grown and conveys this information in respect of natural populations. Among the many new names that have appeared subsequent to my 1999 revision, most simply precipitate collectors back into the good old days when the correctness of any name depended on its source i.e. one was sure of a correct identification only if the plant came from the author of the name or a very close source. There are of course many plants in cultivation that do still carry their original and correct names and Gordon Rowley has listed many of them. They do convey an understanding of the history of Haworthia collecting but largely they are simply labels in the format of two Latin names and seldom convey any information that such a scientific label suggests. Gordon Rowley in private communication also humorously commented on the fact that MBB changes his mind. I cannot apologise for this because the fact is that I cannot even to pretend to understand the complexity that I see. It has been difficult to write some of the preceding chapters for that very reason and I am very dubious that readers will necessarily be able to relate to what I have produced. Certainly the authors of recent new names do not take my work serious and the attitude is quite mutual. Many of the names are attached to my own records and are an essential part of the process whereby I arrived at my list. In respect of virtually every new name I have seen, I am able to include it in this formal summary and account of species that have some rational reality.
