That's a great site, Roy, thanks ... do you do web searches for anybody on demand?

Useful service.
Collin, the source of the number cited in my
guidebook is John Reader's wonderful large-format hardback book called simply
Kilimanjaro (Elm Tree Books, 1982, ISBN 0-241-10683-4). This is worth tracking down in a used book outlet for its superb photographs and well-written text, but if you want to go straight to Reader's source he is a (Swedish?) botanist called Olov Hedberg who, between 1948 and 1979 published a number of papers in learned journals (
Oikos,
Biotropica,
Nature,
Biol J Linn Soc) and who (according to Reader) first listed all 55 species. If you need more detail, give us a fax number and I'll send you that page from Reader's references. But I'm off to look at plant life in Nepal for a month now, so maybe you should ask Roy Hayward to track it down on the web for you?

Signing off, but do keep in touch, Jacquetta
