Alberto I disagree with you that Patrick Synge was one of the greatest bulb experts of his time. He was a very skilled writer and long-time editor of the Journal of the Royal Horticultural Society. He was very good at adapting the writings and ideas of other more expert bulb growers, such as his friends E B Anderson and Paul Furse, neither of whom wrote as prolifically.
