2. Unless the term "floating leaves" is used merely to distin- 

 guish the larger leaves from the smaller it is a misnomer, for 

 they do not always float. Thousands of these "floating leaves" 

 were seen in 1918 and again in 1919, which by actual measure- 

 ment, were submerged at varying depths up to twenty inches. 



3. Fruiting stems are not limited to shallow water. It pro- 

 duced fruit abundantly at Sandy Lake in 191 9 in water of such 

 depth that the combined length of an ordinary oar — 6 ft, 6 in. — 

 and my arm with the sleeve rolled up as far as I could get it did 

 not suffice to reach the bottom. In this particular lake for the 

 past two seasons it has fruited most abundantly in water over 

 six feet deep. 



As northeastern Ohio abounds in small lakes it is not improb- 

 able that other stations for it will be discovered. 



Several sheets of herbarium material were prepared from 



specimens collected at Sandy Lake and will be given to any one 



who may care to send postage for it.

SHORTER NOTES 



CarpoUthes macro phyllus a PHiladelphus . — In Torreya, 191 i, 

 p. 235, I described a fossil fruit from the Miocene of Florissant, 

 giving it the name CarpoUthes macrophyllus, and leaving its 

 classification uncertain. I now find that it agrees in every 

 particular with Philadelphus, except that the sepals are longer 

 than in any living species known to me. It must be called 

 Philadelphus macrophyllus, but it very likely belongs to the 

 same species as P. palaeo philus CkW. 1908, based on leaves from 

 the same rocks. — T. D. A. Cockerell
