BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 87 
* Cornus AmMomum Mill. 
Fringing a brook along the north side of Trots swamp; a 
second locality is at Capaum Pond where there are several thick 
clusters near the shore on the west side of the pond. Cymes just 
appearing June 10, 1908; in full flower July 12, 1910; ripe fruit 
Sept. 12, 1907. 
Nyssa syLvaTica Marsh. 
A common tree on the eastern side of the island, wanting over 
much of the western side; small trees grow on Coatue. Tuckernuck. 
It is ordinarily not taller than 8-10 feet, although trees 15 feet high 
are not uncommon; in Pocomo are groups of larger trees over 
twenty feet in height, and in Beechwood are some that are cer- 
tainly not less than 30-35 feet high, equalling in height the tallest 
red maples. Probably there are no taller native trees anywhere 
on Nantucket. The trunks of these were not as thick as those of 
lower trees on Pocomo where the largest seen was 28 inches in 
circumference. A still stouter trunk of a not particularly tall 
tree in Quaise was 35 inches around one foot above the base. 
Coming into leaf June 3, 1909; anthers visible but not yet mature 
June 8, 1911, June 15, 1908; in full flower and with small green 
fruit June 20, 1910.
