ical leaves involute, 6 to 12 inches long; cauline ones 3 or 4, distant, narrow, 
becoming involute, acuminate, lower 6 to 8 inches long, upper 1 to 2 inches, 
scabrous; ligule 3 to 4 lines long, lacerate: panicle linear, 6 to 10 inches long, 
branches in twos or threes, closely appressed, the lower 1 or 2 inches long, 
flowering to the base, branchlets short and erect; pedicels and rhachis scab- 
in New Mexico. A well marked species.—Dr. GroRGE VASEY. 
Ambrosia bidentata >trifida.—A hybrid from these parents has been 
sent tous by Mr. Eggert, of St. Louis. That district is famous for hybrids, 
Dr. Engelmann having detected so many there, but this one, we believe, is new.

linum Canadense in Indiana.—The discovery of this northern spe- 
cies in middle Indiana is a very interesting fact. Known to students of Gray’s 
Manual as Conioselinum Canadense, or Hemlock-Parsley, its range is entirely 
north of Indiana, except as it finds its way southward along the higher sum- 
mits of the Alleghanies, and is usually found in swamps. I found it a little 
over a mile north of Crawfordsville, clinging to an almost inaccessible bluff 
wall, in surroundings kept constantly cold and wet by springs. It was in both 
flower and fruit October 15.—J. N. Rose. 
Dr. George Martin.—Those interested in mycology will be pained to 
learn of the recent death of Dr. George Martin. The study of our American 
fungi was with the deceased a thing of recent years, and was taken up mainly 
because he saw in it an opening for good work in its relation to practical med- 
icine. However it was not long before he became so interested in these plants 
that almost his whole leisure and strength were given to them. When one 
remembers how many of the specimens in Ellis’ Centuries of North American 
Fungi were collected, and how many more were critically studied by Dr. Mar- 
tin, there will be a surprise to know that he had been for years an invalid 
whose life hung upon the slenderest thread. The deceased left behind him a 
manuscript volume which might well be published as a memorial of his labors. 
It contains a large number of colored illustrations, with spore measurements, 
and descriptions of the fungi he had studied. Such a volume would be a real 
boon to American mycologists. During his life, when urged by his friends to 
publish it, his modesty always led him to evade tke question or to depreciate 
_ the real value of what he had done. He was distinguished as a physician, 
high-toned and honorable as a man, public-spirited as a citizen, and warm- 
as a friend. None can regret his death more than his neighbors 17 
West Chester, Pa., who knew and loved him well.—J. T. RorHRocK.
