probable. The range of latitude will be 50 — 57. And the 

 locality of Mull should be considered slightly within the 

 superagrarian zone. 



311. Lathyrus maritimus, vol. i. p. 328. 



Province 8 may perhaps be now safely regarded in the 

 true ai'ea, although even yet rather uncertain. In a list 

 of Lincolnshire plants, by Mr. (Reverend?) J. H. Thomp- 

 son, obligingly obtained for my use by Mr. Thomas 

 Westcombe, the following note occurs, " I have seen La- 

 thyrus maritimus in an herbarium, which was gathered at 

 Ingoldmills or near it." Range of mean annual tempera- 

 ture 51 — 45, in accordance with explanations given on 

 page 4 of the second volume. 



313. Orobus niger, vol. i. p. 329. 



Mr. Carter confirms the suggestion on page 330, that 

 0. tuberosus was mistaken for O. niger in Staffordshu-e. 



314. Prunus spinosa, vol. i. p. 330. 



Province 6 may be added in the area, on authority of 

 Mr. C. C. Babington. P. insititia has been recorded from 

 nearly all the proviiaces, excepting the North Isles ; al- 

 though held dubiously indigenous in the Highland pro- 

 vinces, as, for instance, by the Flora of Forfarshire. 

 Mr. Gardiner remarks that he has never seen the fruit of 

 P. spinosa ripen in this last named county. 



315. Prunus Padus, vol. i. p. 331. 



Rather dubious as a native in provinces 3 and 4, if not 

 in 5 also. Ascends to TwU du, Caernarvonshire, and to 

 Falcon Glints, Teesdale, stations which may bring it near 

 or within the inferarctic zone. 



316. Prunus Cerasus, vol. i. p. 332. 



Province 6 to be added in the area, on authority of Mr. 

 C. C. Babington, who observed this shrub in Pembroke- 

 shii-e. Perhaps also province 4, on authority of the Flora 

 Bedfordiensis. In addition, the count}'^ of Essex (Mr.
