above the joint. If so, this is the true homologiie of the invoKicel 
of the mallow. But what troubles me is that this minute involucel, 
as it would appear to be, is completely continuous with the base of 
the calyx, and differs from it only in its green instead of red color. 
If this is what Dr. Macloskie has in view, I would like to ask if he 
finds it at all separable from the calyx, and, if not, whether it is an 
organ at all ? And I now wish to insist that in any case, whether it is 
a discoloration or an involucel, it is not the representative of the bract 
or bracts low down on the peduncle of the velvet-leaf.

Note on Juncus trifidus, L.— In looking over some plants col- 
lected in theShawangunk Mountains* last August, I find specimens 
oi Juncus irifidus, L., from the exposed conglomerate ledges at Sam's 
Pomt, Ulster County, N. Y., where it grew plentifully. Mr. C. H. 
Peck mforms me that it is known from but three other localities in the 
State, VIZ., Mt. Marcy and Mt. Whiteface in the Adirondacks, and . 
near Lake Mohunk, the latter station being about fifteen miles 
north of Sam's Point, on the same mountain range.

Death of Dr. George Engelmann— Lovers of the science of bot- 
any will be pamed to learn that the long and active life of Dr. George 
Engelmann was closed on the 4th inst., at his residence in St. Louis. 
Dr. Engelmann was born at Frankford-on-the Main, Germany, 
Feb. 2d, 1809, and was consequently, at his death, seventy-five years 
and two days of age. His university education was acquired at the 
universities of Berlin, Heidelberg and Wurzburg. In 1832 he came 
to the United States and three years after setting foot upon the east- ^ i§\ 
ern shore of the country he found himself in St. Louis, in the heart (^ y' 
of the country. There he began the practice of medicine and con^v \j^7.V 
tinned the study of it and other sciences. In the year iSgoNwas ,^ f , 
founded the Western Academy of Science, Dr. Engelmann beiWg one ^ ^^ / 
of the organizers. For a number of years the society flourished ^J^''^\ 
and then died. He was one of the originators of the St. Louis Med- y^ 
ical society, and was for some time the president of that body. In ^^ 
1856 the St. Louis Academy of Science was organized, and he was 
one of the founders and for many years held the honorable posi- 
tion of president. 
■ As we may expect a full account of his life and labors from the 
hand of one whose name has several times been associated with his 
in botanical investigations, we refrain from giving such details of his 
biography as we find in the daily papers, and which may not be in 
every respect accurate.
