1900] Knowlton, — On the flora of Chesterville, Maine 123 
swamp, Charlton (altitude 640 feet); with the type, but easily dis- 
tinguished by its pale leaves, contrasting with the bright green ones 
of the type. I have also noticed a marked difference between the 
variety and the type in the odor of the flowers. This variety seems 
to be known in New England from a very limited number of stations. 
Kalmia glauca, Ait. Cedar-swamp, Charlton (altitude 640 feet). 
Utricularia purpurea, Walt. Walker Pond (Lake Tantasque), 
Sturbridge, August 13 (altitude 595 feet). 
Lonicera cerulea, L. Wet meadows in the southern parts of South- 
bridge and Sturbridge (altitudes 600 to 840 feet).

ON THE FLORA OF CHESTERVILLE, MAINE. 
C. H. KNOWLTON. 
CHESTERVILLE is one of the southern towns of Franklin County, 
Maine. It affords a great variety of conditions for plant-life and is 
therefore a very interesting field of study. The northern part of the 
town has the ordinary hard-wood growth of the region. Near the 
center is a large sand-plain, known as Chesterville Plains. In the 
southern part is a “ horseback ” four miles in length, called Chester- 
ville Ridge. This has a uniform elevation, and is very nearly straight. 
On each side of it are bogs and ponds. 
It was my privilege, in company with Mr. H. W. Jewell of Far- 
mington, Me., to explore partially this region, Aug. 15-17, 1899. 
We found the following plants, not previously reported from Franklin 
County, and all of them, with the exception of C/adium, from near 
the northern limit of their ranges. 
- Rhus venenata, DC. Margin of Horseshoe pond. A very rare 
plant north of York County. 
Decodon verticillatus, El. Growing on a bog near the margin of 
Round pond. 
Aster nemoralis, Ait. Bog near Locke's pond, N. Chesterville. 
Utricularia resupinata, B. D. Greene. Very abundant on wet 
sandy shore, Norcross pond. 
Fimbristylis autumnalis, R. & S. Same station, not abundant. 
Cladium mariscoides, Torr. Same station.
