250 The Ohio Nauralist. [Vol. V, No. 2, 



CicHORiUM ixTYBUs DiVARicATUM D. C. was Collected bv S. E. 

 Horlacher in Montgomery County in 1903. It differs from the 

 species in having some or all of the heads on stout, divaricately 

 spreading peduncles about 6 cm. long. 



GoMPHRENA GLOBOSA L. is another commonly cultivated 

 plant which has escaped from cultivation. It was collected in 

 1901 by Professor Kellerman at Bowling Green, Wood County, 

 where it was growing along a roadside. 



Thlaspi arvexse L. This introduced crucifer has hitherto 

 been listed only from Hamilton, Lucas and Cuyahoga Counties, 

 indicating a rather limited distribution in the state. Mr. E. F. 

 Lantz has recently given a specimen to the State Herbarium with 

 the report that is it an abundant weed in Henry and Fulton 

 Counties. 



MEETING OF THE BIOLOGICAL CLUB. 



Orton Hall, Oct. 3, 1904. 



President Sanders called the meeting to order. The program 

 for the evening consisted of reports on the summer's work. 



Prof. Hine reported the occurrence of about thirty-five species 

 of mammals in the state, one of the bats being new. Prof. 

 Prosser reported the completion of his work in Kansas and Mary- 

 land. The summer's work has shown that the rocks of the Lower 

 Helderberg or Waterlime in Ohio are much older than has been 

 supposed. The exact geological position of the rocks and faunas 

 about Sandusky was also determined. Prof. Osborn spoke of his 

 work on the Hemiptera of Ohio and New York, several forms 

 having been found which will probably prove new. Prof. 

 Schaffner reported nutation in six species of plants not previously 

 noted ; also work on nodding tips of plants and on Myxomycetes 

 of Clay Co., Kansas. Mr .York reported thirty-six species of 

 plants as new to the Cedar Point list, Fraxinus biltmoreana 

 being new to the state.
