Some of those used for the preparation of this website, or otherwise of general use.

• Trees and Shrubs hardy in the British Isles, originally by William Jackson Bean, (aka Bean's Manual), 8th Edition, 1970/1976. The content of this work has been put in the public domain now, and can be found also in Trees and Shrubs Online. It contains an extensive account of the genus, though largely referring to trees that are grown in Britain, with some comments about nearby Europe. It has been the principal source of information for this website. It also contains accounts of particularly large or fine specimens, often in London and the South East (Bean having been Director of Kew Gardens in the 1920's). Some of these specimens appear to have been lost now.
• The European Garden Flora, vol. IV, contains details of P. orientalis, P. x acerifolia, P. 'Augustine Henry', P. 'Pyramidalis', P. 'Suttnerii', P. occidentalis, P. orientalis 'Digitata', P. racemosa, and P. wrightii.
• Mitchell (Field guide to the trees of Britain and Northern Europe) has accounts of P. orientalis , various clones included under P. x acerifolia, with brief mentions of some other forms.
• Hillier's Manual lists the following additional forms not listed above; P. x acerifolia 'Tremonia', P. orientalis v. insularis .
• Flora of the London Area (London Natural History Society, 1983) contains a plan showing the distribution of reported seedlings within Greater London.
• The "Gardener's Chronicle" in the 1860's carried accounts by Thomas Rivers, of the growth of nursery stock in Britain, and of the cultivar that he called 'Palmata'. Two of them are reproduced on this website - the 1860 article and the 1866 article.
