least twenty-five varieties to show adequately what may be 

 accomplished by the ornamental use of the genus Hemerocallis. 

 Their almost complete freedom from disease and from trouble- 

 some insect pests is a strong recommendation of the daylilies 

 in these days of continuous horticultural warfares. Chapters on 

 culture, seed reproduction, and breeding, an appendix, with 

 much interesting information as to books, persons, and places, 

 and an index, complete the volume. Of the 36 illustrative plates, 

 several are in colors.

Trees of the Southeastern States 1 



Attractively bound in green cloth, this book should prove 

 of real use to those desiring to know the trees of the states from 

 Virginia to Florida. It is written for amateur botanists and 

 nature lovers generally, but is detailed and accurate enough to 

 be of value to the professional botanist. Two hundred and twenty- 

 seven species of trees, native or naturalized, are described. Each 

 species is illustrated with drawings of the leaves and fruit and 

 often of the flowers as well. The key to genera at the beginning 

 is based on both leaf and fruit characters which may at times 

 make it difficult to use in the absence of fruit. Where separation 

 in the key is based on leaf proportions — "blade less than twice 

 as long as broad" or "leaves much longer than broad" — it may 

 be only by the method of trial and error that the sassafras, elms 

 and birches will be found in the latter group. Similarly in the 

 keys to species, given in every case where two or more occur, 

 the separation by leaf size or size of tree may sometimes cause 

 trouble. But as descriptions are ample and the illustrations 

 clear the trouble should not persist. Varieties are discussed under 

 the species, but are not usually included in the keys. Species 

 that seem doubtful are discussed under the forms they most 

 closely resemble: — thus Padus Cuthbertii, neomontana and ala- 

 bamansis are found under P. serotina; Malus glaucescens, brac- 

 teata, redolens, platycarpa, elongata and cuneata under M. 

 coronaria; Fraxinns Darlingtonii under F. pennsylvanica ; and
