diameter of thirty-five feet. Even some oaks show a sHght 

 development of buttresses, extending out horizontally three or 

 four feet from the trunk. These Javan oaks have oblong entire 

 leaves, while the peculiar structure of the acorn cup shows that 

 they belong to an entirely different section of the genus from our 

 American species. 



On the higher ground here is the collection of Dipterocarpaceae, 

 without doubt the most important family of timber trees in the 

 whole Malayan region. All genera of the family are represented 

 except two, and many of them may be found in fruit, so that the 

 botanist can become quite familiar with these interesting trees. 

 The calyx lobes, enlarging in fruit, act as wings for wind distri- 

 bution in many genera, while in others the fruit is heavier, the 

 calyx lobes not enlarged, and the fruit seems to have no special 

 method of dispersal. Those of the latter type may be found 

 under the trees where they have fallen, but the winged species 

 are scattered by the wind and it is sometimes difficult to associate 

 the fruit with the proper species of tree. Some of these weigh as 

 much as an ounce, with wings six inches long, and are probably 

 the heaviest fruits normally distributed by the wind. 



This circuit of the garden brings the visitor back to Canary 

 Avenue. Crossing it, he enters the collection of shade plants, 

 growing in narrow beds under a dense canopy of trees and shrubs. 

 Here are aroids, elatostemmas, begonias, peperomias, calatheas, 

 and many other shade-loving species. The most interesting 

 plants, however, are the gingers and marantas. Next to the 

 bananas, these families include the largest species of monocoty- 

 ledonous herbs. Three or four species exceed ten feet in height, 

 while the huge stems of Nicolaia speciosa arch over the paths 

 and reach lengths of at least eighteen feet. Other species are 

 of course much smaller, and some are mature and bearing flowers 

 at a height of two feet. 



The ginger flower clusters are most striking, and exhibit a 

 great variation in size. In a few, the clusters are almost sessile 

 at the base of the stems. Thus in Achasma foetans , the peduncles 

 are only two inches high, but the flowers are vivid scarlet in color 

 and three inches wide. In other species the peduncles stand six
