oak, and some are lobed, but the most noticeable feature is the 

 rounded base. A rounded base to the leaf is not a usual character of 

 either the willow oak or of the scrub oak, but is often quite prominent 

 in the lingered oak, as is also the white pubescence on the under side of 

 the leaves. The acorns of the scrub oak and of the fingered oak are 

 of about the same size, but in many instances in the trees mentioned 

 they have not as fiat cups as in the willow oak. 



On account of the above characters it is suggested that Quercus 

 digitaia x Phellos should be given a place in the list of hybrid oaks. 



A single hybrid oak with characters much like those just described 

 was found with the Bartram oaks and other hybrids at Richmond 

 Valley, Staten Island, some years ago, and commented on in the Pro- 

 ceedings of the Natural Science Association for October 1888. While 

 the tree resembled those above mentioned, it may be stated that no 

 specimen of Querczis digitata has been found in the vicinity. 



It may be said in conclusion that what appears to be the difiiculty 

 in considering the so called Bartram oak, Quercus heterophylla Michx., 

 is that two or more hybrids have been mixed under the same name. 

 As proof of this we have only to consider the figure given in Sargent's 

 "Manual of the Trees of North America" in connection with what we 

 know to be the conditions at Richmond Valley, where the large, fiat- 

 cupped acorns borne by some of the hybrids, together with the shape 

 of the leaves, indicate the cross between Quercus Phellos and Quercus 

 riibru. Figures of some of these acorns by Dr. Hollick, may be found 

 in the Butleti7i of the Torrey Botanical Club, vol. xv, Dec. 1888, pis. 

 Ixxxiv, Ixxxv, and compared with the figures by Sargent above 

 mentioned. 



SPECIMENS EXHIBITED. 



Mr. Davis exhibited ears of pop corn with mixed red and yellow 

 grains of several colors, the result of cross-fertilization due to raising 

 plants from red and yellow seed in close proximity. 



Mr. Howard H. Cleaves exhibited a living short-eared owl, Asio 

 accipitrinus (Pall.), captured at Princes Bay on February loth. 



Mr. Alanson Skinner exhibited and discussed examples of different 

 varieties of Indian war clubs.
