mature stems are as much as fifteen feet long, and an inch and a 

 half in diameter, and the spreading or ascending leaves are sixteen 

 inches long. The flower stalks are about six feet long, and bear 

 a raceme three feet long and a foot in diameter, with probably a 

 hundred flowers, each of a golden color with brown spots, and 

 almost three inches wide. The lower flowers of the raceme are 

 always sterile. 



The second noteworthy orchid is Dendrobium crumenatum. 

 It grows wild all through the garden, as an epiphyte on all sorts 

 of trees, usually preferring the main trunk or the lower branches. 

 It is inconspicuous in every way, and without flowers might 

 pass completely unnoticed. But on January 31, 1914, thousands 

 of individuals of the species burst into bloom at once, although 

 not a single flower was open the preceding day. All over the 

 garden, but especially among the more open plantings of the 

 Island, the showy white flowers were very much in evidence. 

 The next day they had all disappeared. On February 4 and 5, 

 a few scattered individuals blossomed, but no other flowers 

 appeared on the plants at any other time during our two months' 

 stay at the garden. Just why the species should bloom on this 

 particular day, or what environmental factor is the cause of such 

 behavior, which is a regular characteristic of the species, is by no 

 means apparent. It is probably on a par with the reported 

 simultaneous blooming of the bamboo trees in India, or the 

 appearance of the broods of seventeen-year locust in this country. 



As a mere curiosity, mention should be made of the stemless 

 and leafless orchid Taeniophyllum Hasseltii, whose slender hold- 

 fast roots radiate over the surface of the canary trees, and give 

 the plants the appearance of a long-legged spider. 



Leaving the orchids, one passes through a small planting of 

 cycads, and descends a little hill to the collection' of aquatics. 

 There are two artificial ponds, with numerous species planted 

 close along the shore, within easy distance for inspection. The 

 species exhibit the usual devices for floating, and most of the 

 genera are familiar. Two or three forms exhibit aerenchyma, 

 some along the stems and some on special erect roots. There 

 are vigorous plants of Victoria regia and some interesting speci- 

 mens of the aquatic fern Ceratopteris.
