 Exp. Sta. 6: 40-45. 1921. — The article briefly states the results secured at the Ohio Station 

 from 1910 to 1919 from 93 varieties of apples. The author gives much information in tabular 

 form, including average date of full bloom, average date of 1st picking, average annual yield, 

 highest and lowest annual yields, and number of crop failures of each variety. — R. C. Thomas.

 palm is described and its possible uses indicated. — I. H. Burkill.

 tural plants. A preliminary report. New Hampshire Agric. Exp. Sta. Tech. Bull. 18. 22 p., 

 16 fig. 1921. — The response was somewhat different in different species and horticultural 

 varieties, but always in the same general direction. The area of the leaves studied was in- 

 creased from to 200 per cent; the thickness on the other hand was greatly reduced, as much 

 as 100 per cent in the apple. Shading intensified the green color of the leaves and rendered 

 the surfaces distinctly glabrous. The root systems of all the herbaceous plants were materi- 

 ally reduced by growing the plants in shade. The flowering of practically all the herbaceous 

 plants was modified by shading, and in some cases it was entirely suppressed. Shaded fruit 

 trees also failed to develop flower buds as freely as unshaded ones. In the majority of species 

 studied the shading resulted in a delay in flowering of from a few days to more than a month. —

1109. Kblsey, Harlan P. Official catalog of plant names. Florists' Exchange 50: 103. 

 1920. — This book, soon to be issued, is the result of an extensive piece of work by the Committee 

 on Nomenclature, which represents the associations in the U. S. A. interested in horticultural 

 progress. To the list of plant names which appeared in Bailey's Standard Cyclopedia of 

 Horticulture, 1915, several thousand names have been added, many of them of herbaceous 

 plants and many of them, which have not appeared generally in cultivation, have been newly 

 tested at the Arnold Arboretum. Three societies (American Pomological Society, American 

 Rose Society, and American Iris Society) have furnished complete lists of their respective 

 plant materials. It is hoped that this list wull be adopted by every horticultural society and 

 by the U. S. Department of Agriculture for a term of years in order to standardize plant names. 

 It is considered necessary to establish soon a Plant Registration Bureau with which proper 

 descriptions of newly discovered or originated plants may be registered. It is recommended 

 that the general committee, the American Joint Committee, be made permanent so that 

 needed changes in the Catalog may be noted. It is proposed to hold the book in type so that 

 a more complete edition may be published in about 2 years. — Lua A. Minns.
