Special Papers No. 3, Ohio State Academy of Science, has been distributed. This paper deals with “The Preglacial Drainage of Ohio,” and the authors are W. G. Tight, Granville, J. A. Bownocker, Columbus, J. H. Todd, Wooster, and Gerard Fowke, Chillicothe. The paper is a neat pamphlet of seventy-five pages, with a number of maps and half-tones.

Referring to Burglehaus’ note on Syndesmon (Ohio Naturalist, 1:72), I may say that I have a number of specimens from Eastern Kansas, all of which have sessile involucral leaves. Some of the specimens in the Ohio State Herbarium have sessile leaves, while others have involucral leaves with petioles one inch or less in length. That there can be no mistake in the interpretation of what is supposed to constitute an involucral leaf is shown from the following statement in Britton and Brown’s Flora, 2:50:—“Involucre of three compound sessile leaves; leaflets stalked.” Mr. S. E. Horlacher, of Dayton, Ohio, writes that all the specimens in his herbarium agree with the Flora in having sessile involucral leaves. There may be several forms of Syndesmon distinct enough to designate as varieties; there is at least a large amount of variation.
