reached, doubtless the point visited by Mr. Young. There we 
found the Corenia^ but only sparingly. The hill-top had been over- 
run by fire a few years ago, and it was evident that the plant had 
narrowly escaped extinction. This fact is a suggestive one as con- 
nected with the very local distribution of our Corema, and it is very 
probable that a similar cause has been for ages narrowing its field of 
existence. Yet some new sprouts gave promise of good increase if 
botanists give it fair treatment. The scanty soil in which it grows is 
composed of a finely comminuted granite of which quartz is the 
chief ingredient. Associated with the Corema were Potentjlla trt- 
deniatay Vaccinium Pennsylvantcumy Cornus Canadensis^ with here 
and there a stunted spruce. 
I was then conducted to a bare, round, rocky knob, perhaps 150 
feet in height, about if miles W. S, W. of the locality just mentioned, 
and overlooking Moore*s Harbor. This hill has the local name of 
" Black Dinah/* and on its summit the Corema grows in sufficient 
abundance, in numerous large patches after the manner of Empetrum. 
The rock is composed almost entirely of quartz, and the scanty soil 
is made up of its particles, and an occasional rock crevice gives foot- 
hold for the firmly rooted Corema. The associated plants were 
mainly the same as in the locality last mentioned, except that a fe\v 
dwarf examples of Pinus rigida were scattered about. I "was in- 
formed that a third locality exists on the rocky shore between Black 
Dinah and the little village opposite Kimball*s Island, and another 
on the eastern side of the island. Empetrum nigrum is also found 
on Isle au Haut, and on the neighboring Kimball's Island, and is 
very abundant on many of the rocky headlands of Mt, Desert twenty- 
five or thirty miles distant, and I have recently been informed that 
Corema has been seen upon Green Mt., the highest part of Mt. 
Desert, but I need some more positive evidence that the plant there 
seen was not Empetrum, and further search in other of the many 
large islands of Penobscot Bay some of them many square miles in 
area, and upon the numerous promontories of the main land will 
probably yet reveal other localities 
Nova Scotia and Netvfoundland. — Mr. Tuckerman saw in the 
Lambert Herbarium in London specimens collected in Newfound- 
land by Cormack. In Nova Scotia it has been seen in Halifax Co. 
by Lindsay and Sommers, and at Wilmot, Annapolis Co., by Howe. 
I know nothing further as to these localities, but hope that our bo 
tanical brethren from the British Provinces will give us further facts. 
7. Shawangunk Mis,, N, 3^.~A11 the localities hitherto men- 
tioned are maritime, or so near the sea^coast that when in 1881 i 
was announced that the Corema existed in Ulster Co., N- Y., on 
mountain top, eighty miles from the coast, some surprise ^^^J^^^^ •! 
and botanists were led to call to mind how, in like manner, Hudson 
and Leiophyllum are perfectly at home on mountain sumrmts 
North Carolina. Mr. Smiley, proprietor of the Minnewaska Kous^, 
a well-known summer resort in the Shawangunk Mountains, 
1 88 1 called the attention of Aubrey H. Smith to the plant w 
identified it as Corema, and reported the fact to the Botanical a
