The number and arrangement of the involucres varies considerably in 

 the same plant and even in adjoining leaf-axils, as also does the number of 

 flowers to the involucres of the same axil. I have found six to each of two 

 opposite leaf-axils, making twelve at a node, two of these with three males 

 and one female flower, four with one female flower only. An involucre of 

 three or four male flowers may easily be mistaken for a normal flower with 

 three or four stamens unless the flask- shaped perianth to each stamen is 

 noted. 



In. t. 240: a a. four-toothed involucre with bract, behind, and in it three 

 male and one female flower ; ^ plan ( "^ male flower (7) female). 



CUPULIFER/E. 



QUERCUS. F.B.I. 140 III. 



Oak. 

 Trees with alternate toothed or lobed leaves, and 

 small unisexual flowers. Male flowers in erect on pendu- 

 lous spikes, with four to seven perianth lobes and many 

 stamens. Female flowers enclosed at first by imbricating 

 bracts, which enlarge as the fruit grows and become 

 a cup with the nut (acontj seated in it. 



Species about 300, mostly of north temperate regions and 

 specially in North America.
