Almost concealed from view, up the bank, on the 

 right of the Walk, is a fair specimen of American 

 bladder nut, which you can identify by its leaves, 

 which are in leaflets of three. Its flowers are very 

 pretty, in white racemed clusters, in April or May. 

 These flowers change to bladder-like pods. 



Just beyond the Cephalotaxus, on the right of the 

 Walk, you come to two very good specimens of the 

 Western or hardy Catalpa, Catalpa speciosa. The first 

 one is just a little diagonally across from the Cepha- 

 lotaxus. The second is directly opposite a fine black- 

 barked, lovable old honey locust, which is just beyond 

 the Cephalotaxus, on the left of the Walk. There are 

 several more of these Catalpas along here, and they 

 furnish a good chance to note how very different 

 they are from Catalpa bignonioides. The speciosa 

 grows tall, Y-form, and branches high up, while the 

 bignonioides branches low, with a rambling, sprawling 

 reach of boughs which gives it a bunchy head, strik- 

 ingly distinctive from the erect, almost elm-like form 

 of the speciosa. How different they are in bark. The 

 hardy or Western catalpa's is thick, runs in longi- 

 tudinal lines and fissures something like the habit of 

 the basswood, while that of the bignonioides seems thin 

 and scale-like over a smoothish underground of dull 

 brownish gray, with nothing of the longitudinal run 

 of fissure. These scales seem to almost tempt the 

 finger to pick at them. The speciosa, as has been 

 said, is a tall tree with thickish bark. Its leaves are 

 downy and soft, heart-shaped and noticeably long- 

 pointed. Its flowers also differ from the bignonioides
