THE JOUllNAL OF BOTANY 
The Naturalist for March contains the very interesting presi¬ 
dential address on “ Botanical Survey and Ecology in Yorkshire,” 
delivered by Mr. T. W. Woodhead at the meeting of the York¬ 
shire Naturalists’ Union held at Scarborough in December last. 
Beginning with a comprehensive sketch of the floras of the county 
and their authors, and of the survey in which Messrs. Moss and William 
G. Smith took so prominent a part, Mr. Woodhead proceeds to 
summarise the ecological aspects of the flora. A useful and com¬ 
prehensive bibliography is appended to the paper, which includes 
some interesting portraits. 
In Bhodora for February, in the course of some notes on 
“ Critical Plants of North America,” Mr. C. E. Weatherby discusses 
some species of Chelone with especial reference to Clayton’s and 
Miller’s descriptions—the reference to Miller’s plate should be 93, 
not “ 19.” It would be well if some American botanist, when 
visiting the National Herbarium, would examine the specimens from 
both the writers cited; in the absence of authentic material, it seems 
hardly possible to arrive at any definite conclusion as to the species. 
The Beport of the National Museum of Wales for 1921-22 
shows that steady progress is being made with the Welsh herbarium; 
the botany department has been enriched by the purchase of 
Mr. E. M. Holmes’s herbarium of algse, mosses, and hepatics. Loan 
collections containing economic specimens, tropical fruits and seeds, 
and herbarium sheets of Welsh plants, have been prepared for and 
installed in three secondary schools—a useful piece of work. 
The Annals of the Missouri Botanic Garden (ix. no. 3; Sept. 
1922) lately to hand is mainly occupied by a “ Monographic Study of 
Thelypodimn and its immediate allies,” by Mr. E. B. Pa 3 ^on ; Mr. G. 
H. Pring describes and figures a new hybrid Nymphcea —“ x Nymphsea 
‘Mrs. G. H. Pring,’ Pring, n. hyb. (W. ovalifolia 5 X N ‘Mrs. Ed¬ 
wards Whitaker ’ <$ ).” 
The Botanical Gazette for March contains a paper by M. C. 
Sewell on the “ Effect of Andropogon Sorghum on succeeding crops 
of Triticum sativum vulgare ” ; J. W. Bailey continues his “ Notes 
on Neotropical Ant-plants,” with a study of Tachigalia paniculata , 
and Charles Robertson concludes his series on “ Flowers and Insects,” 
the terminology of which will afford Dr. Jackson matter for the next 
edition of his invaluable Glossary. 
A handy little pocket manual in which are described and figured 
the Common Forest Trees of North Carolina , prepared by J. S. 
Holmes, State Forester, in connexion with the Forest Service of the 
U.S. Department of Agriculture, is published at Chapel Hill, N.C. 
The Bulletin of the Torrey Club for March contains a paper 
(with plate) on “ Polyembryony developed under experimental con¬ 
ditions in certain Polypodiaceous Ferns.” 
The Imperial Botanical Conference which meets in London next 
year has appointed a small subcommittee to consider questions of 
nomenclature, the convener of which is Mr. T. A. Sprague.
