SOME BLUEBERRIES OF MARLBORO, N. H. 
Southern New Hampshire is noted for the great abundance 
and variety of its blueberries, so that I was glad of an opportunity, 
during the middle of July of the present year, to make collections 
there for the Economic Museum of the Garden. In doing so, 
I found the varieties and forms so numerous, and their relations 
so interesting, as to be worthy of published record. 
Most of my studies and collections were made on the estate 
of Mrs. B. C. Knight, of Marlboro, and the adjoining one of 
Mr. Baker. The plants grew in rocky pasture land, mostly 
rather dry, but with some damp spots. Practically all of the 
forms described grew on the dry lands. 
I found no specimen of Gaylussacia, nor any of the section 
Euvaccinium, nor was I able to learn that any of either group 
occurs in the region. My observations were confined therefore to 
the corymbosum and pennsylvanicum groups of the section 
Cvanococcus. All the forms here described are represented by 
specimens in the Garden Herbarium, designated by the numbers. 
here employed preceded by the word “Marlboro.” Most of 
these are also preserved in formaldehyde in the economic museum 
but do not there bear these numbers. 
Had all definite, or even all striking forms been collected, the 
number would have been considerably larger, for there are con- 
spicuous differences in habit of growth, as well as in herbarium 
characters, which cannot be overlooked and which are constant 
in numerous individuals. So numerous are the forms and so
