CASUALS AND ALIENS 
IN THE DEWSBURY DISTRICT IN 1893. 
P, FOX LEE, 
Dewsbury ; President of the Botanical Section of the Yorkshire Naturalists’ Union, 
As a consequence of the exceptionally dry sunny weather of 
the spring, summer and autumn of this year, a large number of 
these wool-and-grain-brought plants have been able—contrary to 
their usual experience under the generally adverse meteorological 
conditions prevailing in these climes—to pass safely through the 
flowering and fruiting stages, thereby not only reminding them of 
their native countries, but, alas! rendering them an easier prey to 
the botanist : seeking what he may devour. 
I here desire to tender my thanks to Mr. F. Arnold Lees, and to 
Mr. W. Carruthers, Keeper of the Botanical Department of the 
Natural History Museum, South Kensington, for kindly help in the 
determination and confirmation of the names of the exotics. Those 
marked with an asterisk have not hitherto been placed on record for 
this immediate district, and those with a dagger prefixed are additions 
to the flora of the Riding, i.e., not mentioned in ‘ The Flora of West 
Yorkshire.’ . 
On the banks of the river Calder and the Canal and on wool- 
refuse and waste ground at Ravensthorpe and Mirfield, the following 
observations have been made :— 
Raphanus sativus W. Calder bank; a very noticeable plant.
