NOTES ON GEOLOGY AND BOTANY OF DIGBY NECK BAILEY. 79 



Lily (Nuphar advena) was also common, but Nymphaea 

 odorata, the white Water-lily, was seen at one point only, in 

 the little pond midway between the northern and southern 

 outlets of Sandy Cove, its occurrence here being in keeping with 

 the warm and sheltered position of its habitat. 



The southern side of the peninsula, fronting St. Mary's Bay, 

 may perhaps be regarded as forming another zone, but is less 

 well-defined than those previously noted, and marked rather by 

 the more general prevalence of broad-leaved trees and their 

 comparatively vigorous growth, than by the occurrence of any 

 special species. 



Finally, over the red sandstone district constituting the 

 isthmus connecting Digby Neck with the mainland, the species 

 found are the same as those of the Annapolis Valley, of which 

 pretty full lists have been elsewhere published. The growth of 

 the Horse-Chestnut is especially noticeable. 



Towards the western extremity of the peninsula and upon 

 Long Island, its natural extension, the above zones (excepting 

 the last which is here wholly wanting), tend to blend or to dis- 

 appear, while the increasing amount of low and boggy ground is 

 accompanied by the corresponding augmentation of ericaceous 

 plants, such as Vacciniums, Ledum, Kalmia, Cassandra, &c. 

 Potentilla fruticosa was also noticed here at several points, 

 forming dense clusters. P. anserina was also of common occur- 

 rence. Finally, over the surface of peat bogs, especially on Briar 

 Island, were to be found the different species of Drosera (D. 

 rotundi/olia and D. intermedia), Sarracenia purpurea and the 

 Orchids Habenaria psycodes and H. blephariglottis. Nowhere 

 have I seen these Orchids so abundant as over the barrens and 

 peat bogs of Digby and Yarmouth Counties. 



Appended is given a more complete list of the plants observed 

 on Digby Neck. While by no means embracing all the species 

 which are doubtless represented there, it may be useful as a 

 basis both for comparison and for further exploration.
