longer catkins of staminate (pollen bearing) flowers, 

 than our native chestnut. These long, spike-like, stam- 

 inate catkins of the chestnut are very beautiful, in the 

 height of their bloom, seeming to cover the tree with 

 cream-white tufts. These staminate catkins are long, 

 greenish spikes along which the tiny little stamen

 The fertile or pistillate flowers are inconspicuous. If 

 you look close you will find them at the bases of the 

 sterile (staminate) catkins, highest on the branches, or

Cornus sericea. {Swamp Dogwood. Silky Dogwood.

 A cyme is usually a flat cluster of flowers in which the 

 central flower opens first and the others after. This 

 blooming, or inflorescence, as it is termed botanically, 

 is called centrifugal, i. e. from the center outward, and 

 is the distinguishing feature of the cyme. The indi- 

 vidual flowers in the flat-topped clusters of the shrub's
