262 BAKER'S^NORTH YORKSHIRE. 



Tanfield Church, Upsal Castle, Danby Castle, St. Mary's Abbey, 

 and Chfford's Tower at York, etc. Indigenous in Greece and 

 the south-west of Europe. 



Hesperis matronalis L. Alien. Occasionally subspon- 

 taneous by stream-sides and in waste ground. Lonton, Lar- 

 tington, Richmond, Aysgarth, Wensley, Hutton Conyers, 

 Rievaulx, etc. Grown in gardens up to 350 yards. 



Brassica oleracea L. Atlantic type. Denizen. Area 4. 

 Range Coast-Level. HuntcMffe ; D. J^erguson. Plentiful amongst 

 the coast precipices in the vicinity of Staithes, whence it is 

 recorded in the original Botanist's Guide by Archdeacon 

 Peirson, and where I saw it in plenty in 1881, but near the 

 village only. It occurs in more suspicious stations near Whitby 

 and Scarborough, and is an occasional weed of cultivated fields 

 inland. It is grown up to 500 yards, but will not stand the 

 winters of our middle zone. 



Brassica Napus L. English type. Colonist. Area general. 

 Range 0-300. Cultivated throughout the lower zone and fre- 

 quently subspontaneous by stream-sides, etc. Apparently 

 indigenous in Scandinavia and Russia. 



Brassica Rapa L. English type. Colonist. Area general. 

 Range 0-300. Cultivated up to 500 yards, but like all the other 

 cultivated crops, only grown casually above 400 yards. Upon 

 the heavy soils of the Lias and Gritstone the turnip and oat are 

 more profitable and successful than anything else. Like the 

 preceding, it is frequent in a subspontaneous state in cultivated 

 fields and along streams, and for its original home we must 

 probably look in the same direction. 



Sinapis arvensis L. British type. Colonist. Area general. 

 Range 0-350. One of the commonest weeds of cultivated fields, 

 and ascending as high as field-cultivation reaches. 



Sinapis alba L. English type. Colonist. Area 98765432. 

 Range 0-200. Occasionally grown in fields and gardens up to 

 500 yards, and sometimes occurring as a weed. The highest
