SCIENCE, 



[Vol. VI., No. 142. 



esting feature of the Nantucket flora is the existence 

 of three species of heath under circumstances that 

 lead to the belief that they are indigenous. Mr. 

 Eedfield has not seen the locality of Colluna vulgaris, 

 but had seen that of Erica cinerea. The latter has 

 been known and watched for ten or twelve years 

 and is evidently long established. It grows in the 

 open common, far away from the town, and there is 

 nothing about its surroundings to indicate human 

 introduction. It covers only a space of eight inches 

 by ten. Since Mr. Eedfield's visit he had learned 

 that another and possibly a third locality of heath 

 had been discovered widely distant from the first, 

 and that in one case the species proved to be Erica 

 tetralix. He held that the discovery of so many 

 species, and these the same as a^'e found associated in 

 England, pointed strongly to an indigenous origin. 

 Mr. Meehan in continuation described the associated 

 growth of the three species of heath on the Isle of 

 Wight.
