EDITORIAL As I write this newsletter the winter solstice has just passed, but although the days will be lengthening, the coldest weather has yet to come. There were exceptionally heavy rains and cold weather in May - not usual for us here on the high veld. Clivia have been flowering out of season and most of us have very little seed ripening. Lily Borers have had a wonderful time destroying as much as they can, and just when you think you have them under control, they appear somewhere else! Plants under cover have not fared too badly, but most of us have our plants out in the open. We have contributions from all over South Africa and from all the continents except Asia. Dries Bester talks about successful germination of seedlings, describes a snippet from an old magazine, and has a list of prices of Clivia. He seemed very pleased about the Clivia caulescens tour which he led last year. We hope he is still enthusiastic when those of us who were unable to go last year contact him for a tour this year! Gert Wiese clarifies points on yellow Clivias. All the controversy on yellows really points to a need for a classification of the known varieties with proper nomenclature. Lynette Lotz has mentioned some interesting aspects in her letter: seedlings without chlorophyll, suggestions for the newsletter, and ideas on how to boost the club. We hope to institute a coloured supplement for members soon. There are two letters from Les Hannibal in California. The first gives a description of what is supposed to be a Belgian hybrid - here again a photograph would help with the identification. And yes, when is someone going to describe this in the botanical literature? Come on, all you budding botanists! Les Hannibal's second letter describes some of the intricacies of bigeneric hybrids and successes with Crinum

    in particular. This letter will also serve as the scientific article for this newsletter. There has been no success in finding a "white" clivia. Kees Sahin was able to furnish a possible source, but when followed up this turned out to be a pale cream. Sir Peter Smithers has given an e-mail number on which there is a picture and a write up about Clivia x Kewensis `Vico Yellow'. Keith Hammett reports that little progress has been made with Clivia research at his university in Auckland, New Zealand. One student discontinued his studies and another has recently started. Bill Morris has raised more interesting points on the origins of Belgian Hybrids and we hope readers will be able to contribute more to this discussion. Jakes Naude is growing seedlings hydroponically in vermiculite with good results. He asked for information on pests and diseases and as these topics were discussed at both the Gauteng and the KwaZulu/Natal Clivia Club meetings, we have given a breakdown of one of them in this issue. Both meetings were well attended and helped to enthuse members even more about their hobby. I was at the North Coast recently and decided to collect the KwaZulu/Natal news in person from Val Thurston, the secretary of the branch. Needless to say, I got lost in the sugar cane near Tongaat. I couldn't help thinking how many pockets of indigenous bush with Clivia in them must have been cleared to make way for all the sugar cane along the coast. Here we decry the ravages made by the herbalists when we, the so-called first world communities, probably do far more damage to the environment when clearing for farming or housing. Val Thurston has photographs of lovely yellow Clivia and is busy classifying them. I hope we will be able to publish this sometime in one of our newsletters. A few of them have very wide stems with distichous leaves much like those of the broad leafed varieties. I had always thought that these were only found in hybrids, but the
