parently entire about the margin, if you look at them 

 closely with your hand lens, you will find that they 

 are very finely cut with rounded teeth. On the under- 

 sides the leaves are slightly glaucous, but on the 

 upper, they are smooth (glabrous) and of a dark 

 green. The leaf stalks are interesting, dark red in 

 hue, and jointed beyond the base. The flowers are 

 not conspicuous, without petals and solitary. These 

 develop into pods which are dehiscent, that is, split 

 open in a regular way, to discharge the seed when 

 ripe. These pods, usually two to four, break open 

 along the outer seam to discharge the seeds. The 

 seeds have membranous wings. The Katsura is a

 up to the type. The tree belongs to the magnolia 

 family.

 the Acer Italum, you will find a small tree bristling 

 with thorns and with small, thick, leathery and very 

 glossy leaves. These leaves are broad at the end, 

 and gradually narrow down to a long, thin, wedge- 

 shaped base, not unlike a miniature lacrosse stick. If 

 you have learned the look of the cockspur thorn's leaf, 

 the leaves of the tree must instantly suggest that tree 

 to you. They look like a cut-down similitude of the 

 cockspur's leaf. This tree is not a large one, and you 

 can pick it out easily by its thorns. It is too bad that 

 both this tree and the Italian maple should be in this
