138 Rhodora [AUGUST 
which includes Schoodic, but not to the small islands of the outer 
part of Gouldsborough and Dyers Bays. It occurs upon Mt. Desert! 
and Great Wass Island;? also on Steele Harbor Island (C. A. Cheever 
in herb. New England Botanical Club). 
PICEA CANADENSIS (Mill.) B.S.P. Abundant on many of the islands 
east of the St. Georges group. At Eastern Ear, Isle au Haut, on the 
south side exposed to the force of sea breezes and gales, trees ten or 
more feet high are so dense that a person of two hundred pounds weight 
may walk from the ground to the summit on the ends of the densely 
matted and tangled branches. West of St. Georges it becomes less 
abundant, and at Casco Bay is decidedly rare, though a few trees occur 
at Trundys Reef, Cape Elizabeth. 
JUNIPERUS HORIZONTALIS Moench. Crumple Island, near Jones- 
port; Matinicus Seal Island, in abundance; Big Two Bush and White 
Head, Knox County; Pumpkin Knob near Damascove Island; 
Western Brown Cow and Marsh Islands, Casco Bay. Known in 
some sections as Slink Weed. Distribution local. In the herbarium 
of the New England Botanical Club are specimens from Monhegan 
Island (Miss Furbish). 
TYPHA ANGUSTIFOLIA L. The easternmost recorded stations on the 
Maine coast are Great Chebeague, Casco Bay, and Winnegance.? 
SPARGANIUM ANGUSTIFOLIUM Michx. Rare at Matinicus Island. 
IRIS SETOSA CANADENSIS Foster. This plant, the interesting his- 
tory of which is shown in the pages of Ruopora,‘ abounds on most of 
the islands (excepting Machias Seal Island) east of Petit Menan 
Point. West of this point it becomes very local, and generally rare. 
It abounds, however, on Cranberry Point in the town of Gouldsboro, 
but is recorded as rare at Great Cranberry Island;5 and in 1911 I found 
a few plants on Little Duck Island, its southwestern known limit at 
this time. 
Iris PRISMATICA Pursh. On the 31st of July, 1903, I had occasion - 
to visit Flint Island, Naraguagus Bay. While I was occupied with 
the object of my visit, Mrs. Norton discovered a number of sterile 
plants of a very slender Iris markedly different in appearance from the
