Orchids of Britain & Ireland: a field and site guide
An excellent modern work on orchids with copious excellent photographs and detailed accounts of biology and distribution. The site guide includes orchid locations in every county.
A large book at nearly 500 pages which shows how much is known about our orchids, but also how little is known about their pollenators or mycorrhizal fungi - both fundamental to conservation.
Use of the latest DNA-based nomenclature may initially confuse experienced botanists.
