which were numerous, were very coarse in appearance, and the 
specimen taken was a small one. Even the coarse appearance of this 
is noticeably different from that of taller specimens of A. drummondi 
from western Maine, and the ripe pods reach fully 3 mm. in breadth. 
It seems best referred to Arabis drummondi connexa (Greene) Fernald. 
ARABIS HIRSUTA (L.) Scop. “Oyster Banks," east side of Damaris- 
cotta River, Sept. 15, 1912. 
SEDUM ROSEUM (L.) Scop. Reported as new to the flora of Maine 
in 1863 by Prof. A. E. Verrill in 1865,! and is admitted in fifth edition 
of Gray's Manual? It was next recorded from Cutler by Harvey 
and Briggs,’ followed the next year by Rand and Redfield, as rare 
at Dog Mountain, and Egg Rock, Mt. Desert.* In 1902 Miss Dora 
Moulton published its occurrence at Point of Main, Englishmans 
Bay,‘ and later, Mr. Joseph Cushman published the fact of its general 
distribution in this and adjacent bays.* To his list of stations should 
be added Pulpit and Freemans Rocks. To the westward of Great 
Wass Island it is common on Crumple Island and several of the small 
adjacent rocks. This seems to mark its limit of general distribution 
westward as it is not noticeable on the rocky islands off the eastern 
part of Gouldsborough and has not been noticed in Jericho and 
Penobscot Bays.” At Matinicus Seal Island and Rock it is abundant, 
but I have not myself found it west of these islands. It is not in- 
cluded in Miss Mabel P. Cook's list of Monhegan plants,® but there 
are specimens in the herbarium of the New England Botanical Club 
collected on Monhegan in 1901 by C. F. Jenney and in 1910 and 1911 
by Miss Kate Furbish. l

7 I have not landed on Schoodic Point or Island nor the main island of Isle au Haut; 
these bold headlands seem to furnish ideal conditions for the plant, and it is to be 
expected there. However, I have not found it at the eastern Ear of Isle au Haut 
apparently suitable for its needs.
