amusing things to say about pergolas, and will only permit them as 

 useful supports for climbers, and does not seem to realize that among 

 Roses 'Jersey Beauty,' and of Brambles Rubus flagelliformis and k. 

 bambusarum, and also Clematis Armandii, can be very beautiful 

 throughout an average winter even when on a pergola. So, having 

 found all the fault I can with this almost perfect book, I return to 

 my main proposition — that here we have a very valuable guide to 

 climbing plants, in a small compass and at a very reasonable price. 



" Popular Hardy Perennials." By T. W. Sanders, F.L.S. 

 (Collingridge, London [1915]). 5s. net. 



Adds one more to the books designed to assist readers of 

 limited knowledge and experience in rinding worthy herbaceous plants 

 for their borders. Its value to such will depend on the youth and 

 credulity of the reader, and a certain amount of chance. For in an 

 attempt to include all possibly popular perennials the writer has evi- 

 dently gone beyond a personal and accurate knowledge of many. This 

 is very noticeable in the dates of flowering given. For instance, those 

 who expect flowers from Anemone Pulsatilla from May to June or from 

 A. blanda in April will be disappointed in finding only seed-heads. 

 Eremurus Olgae is the latest of all the species, and never, unless 

 severely forced, flowers in May or June. Epimedium pinnatum, again, 

 is in flower with the Wood Anemones and not in June. No word of 

 warning is given to show that Yucca aloifolia and Incarvillea variabilis 

 are not hardy, or that Tellima grandi flora's yellow flowers are by no 

 means showy. 



Lysimachia clethroides is named Lythrum Salicaria roseum 

 superbum under its portrait. N. America is given as the home of 

 the European Gentiana Asclepiadea. Salvia Sclarea is not perennial. 

 The young may live long enough and the incredulous search further 

 to discover the truth. A careful revision could make the book useful, 

 for its plan is good, and the number of illustrations from photographs 

 of the plants themselves, as well as of well-furnished borders, are very 

 numerous, and some excellent. Others are taken from such poor scraps, 

 as those of Saxifraga cordifolia purpurea, Pulmonaria saccharata, and 

 Onoclea sensibilis, as to give but little idea of the value of the plants. 



There are also useful lists at the end of the book of perennials 

 arranged as to colour, fragrance, for town gardens, woodlands and 

 chalky soils. 



" Principles of Plant-Teratology." By W. C. Worsdell, F.L.S. 

 Vol. 1. 8vo. xxiv -f- 270 pp. 25 plates. (Ray Society, London, 

 1915.) 25s. net. 



In 1869 the Ray Society published "Vegetable Teratology: 

 an account of the Principal Deviations from the Usual Structure of 

 Plants," by Dr. Maxwell T. Masters. It is the best known, and 

 probably the most used, of all the Ray Society's botanical publica- 

 tions, and it took its place at once as the standard publication in
