30 a. Panicum boscii molle ( Vasey) Hitche, and Chase. Much 

 like P. boscii except not quite so tall and downy pubescent thm- 

 out. Hamilton, Lawrence, Cuyahoga. 



31. Panicum chandestinum L. Hispid Panic-gra.ss. An 

 erect or ascending rather stout perennial, simple at first but much 

 branched laler in the season. Sheaths longer than the internodcs, 

 papillose-his])id. especially the upper ones; leaf-blades 2 to S inches 

 long, ^2 to lJ-4 inches wide, cordate, clasping, glabrous, ciliate at 

 the base; primary panicle o to o inches long, branches ascending, 

 often long-c.xserted. secondary ]janicles often inclined; spikelcts 

 I inch long, pubescent, eli]jtic; outer empty glume | as long- 

 as the spikelct ; the second empty gltmie 9 nerved. In moist 

 thickets. General. 



MEETINGS OF THE BIOLOGICAL CLUB. 



Orton Hall, February 2, 191 1. 



The meeting was called to order at 7:30 by the President, 

 Mr. Kostir. The minutes were read and approved. The fol- 

 lowing were elected to membership: Eric S. Cogan, Fred Pcrr\', 

 Gertrude Bartlett, Malon Yoder, Rudolf Pintner and Newton 

 T. Miller. 



The first paper of the evening was a review of the thesis on 

 the study of "Capillary Movement of Soil Moisture, " by Malcolm 

 Sewell. There are three reasons why a plant may not get suf- 

 ficient water. First the soil water may be gone, second the 

 transpiration may be greater than the absorption and thirdly 

 the transpiration may be greater than the ca]Dillary action of the 

 roots. A })lant niay draw water from a much larger area than 

 that in which the roots are, due to capillary action. Mr. Sewell 

 then showed a dozen or more slides showing pictures of his tanks 

 in which he grew the corn on which he leased his conclusions. 

 One tank had no concrete bottom. The others had concrete 

 bottoms in which he kept the water levels at three and five feet, 

 respectively. He found that the best results were obtained in the 

 tank without a concrete bottom. 



Prof. Osborn next gave an illustrated talk on his trip to 

 Maine. He said that there is little known about Maine and that 

 much of the State is unexplored. Much of the timber is wasted 

 by poor means of lumbering. The path that he took up Mt. 

 Katahden was that of an old avalanche. The trip up was a hard 

 one due to the rough out-crop of huge rocks. The purpose of 

 his trip was to collect leaf hoppers. 



Mr. Reed gave a review of some papers read at the meeting 

 of physiologists held in Philadelphia. 



Blanche McAvoy, Secretary.
