PAULOWNIA. 

 (Family Scrophulariaceae).

 Twigs stout, resembling those of 

 Catalpa, compressed at the nodes: 

 pith large, white, roundish, chamb- 

 ered or hollowed out between the 

 nodes. Buds superposed, sessile, 

 half-round, with about 4 exposed 

 blunt scales, the end-bud lacking. 

 Leaf-scars opposite, subelliptical, 

 more or less notched at top, raised: 

 bundle-traces many in a nearly 

 closed and sometimes almost con- 

 tinuous ellipse: stipule-scars lack- 

 ing. The rather large ovoid cap- 

 sules persistent.

The compact wood of Paulownia 

 is said to be a favorite for mak- 

 ing tea boxes in Japan, retaining the aroma of the tea well. 



Paulowina tomentosa is not hardy in the northern inte- 

 rior where, if at all, it is seen usually in the form of strong 

 large-leaved suckers from the persistent roots, but it is one 

 of the conspicuous trees in front of the Smithsonian building 

 in Washington, and has been used as a street tree as far 

 north as Brooklyn near the coast. 

 Minutely velvety. (Imperial tree). P. tomentosa.
