In the " Ramble " Fourth Excursion 



having one of the most distinctive types of leaf, of leath- 

 ery texture, dark green and lustrous above, whitish be- 

 neath, and with a deeply serrate -cren ate edge a leaf 

 that would attract notice, looking more like a Quercus 

 than a Pyrus. Its outline is on Plate IV. of foreign 

 trees. 



The other discovery was a Japanese tree (Idesia poly- 

 carpa), whose leaf misled a gardener into calling it a 

 mulberry, but when I called his attention to the abun- 

 dant clusters of small yellowish flowers, it was conclusive 

 evidence. This will be found overhanging one of the 

 walks near the Conservatory. 



Besides the four routes of our excursions one can take 

 many other walks that are favorable for botanical ob- 

 servation. Of these I would especially recommend the 

 paths along the " West Drive, " from Fifty-ninth to 

 Seventy-second Street, the vicinity of the East Seventy- 

 second Street entrance, the circuit of the so-called 

 "Pool" on the west side, at about io2d Street one 

 of the most delightful spots in the Park the paths in 

 the vicinity of the Conservatory at East io6th Street, 

 and the circuit of "Harlem Mere," at the extreme 

 northeastern corner of the Park.
