Alberto & Diana, I am not at all surprised at the lack of Oxalis coverage in the book for the reasons stated by Diana, ie lack of available contemporary keys. Very few people in S Africa appear to have an active interest in the genus, in contrast to the situation with the monocots. I notice that a copy of the Salter monograph is currently listed on the Clarkes bookshop site at http://www.clarkes.co.za/ in catalogue #15. However, the price ($750 /GBP500 !!!!!) may prove to be a bit of a disincentive to purchase! On the bright side at least you have your copies of the Cape Bulb Encyclopedia - mine, ordered through AGS, has yet to arrive! Best wishes Robin Attrill
