Winter-character reference to 

 Pterostyrax hispida: Schneider, 

 f. 87. 



Pterostyrax is considered not 



generically different from HaleHa 



by some botanists, and, as its 



generic name indicates, it bears 



winged fruits like HaleHa. 



Though they do well in the South, its species are even less 



dependable in the North than the silver bells. 



Twigs with quickly shredding gray bark. P. hispida.
