with the odor of pineapple. Another is Monstera late- 
vaginata; the early leaves differ widely from the mature 
ones. The main aroid collection will be found in house Io, 
and other plants at range 2. 
A large tree of the common rubber plant, much grown in 
parlors, may be found in the center of this house, reaching 
to the roof; this is a native of tropical Asia and yields some 
rubber, but not in as great quantity nor of as good quality 
as the other rubber trees of South and Central America; it 
is a species of fig (Ficus elastica); other species of Ficus are 
shown in this house, notably a fine tree of Roxburgh’s 
fig, which bears its inedible fruit in bunches near the base of 
the tree, and a specimen of the Banyan tree (Ficus beng- 
halensis). Chocolate trees (Theobroma Cacao), native of 
tropical America, may be found near the northern door of 
this house; the small white flowers are produced on the 
trunk and on branches, and a few of them develop into 
the large woody pods containing the seeds or chocolate 
beans, which are dried and ground up into chocolate 
and cocoa; specimens illustrating the chocolate industry 
will be found in the economic museum. The papaya, or 
papaw, also of tropical America, is here also; its fruit, 
esteemed as an aid to digestion, is borne just under the 
crown of leaves. A specimen of the bread-fruit tree 
(Artocarpus incisa) may also be seen here; originally from 
the islands of the Pacific, it was introduced into the West 
Indies in the latter part of the eighteenth century. 
Several interesting tall vines climb on the pillars of this 
house, and on supports along the sides, among them the 
night-blooming jessamine (Cestrum Pargui) of tropical 
America, which opens its flowers after dark and exhales a 
delicious perfume, the flowers remaining open during part 
of the morning; Henderson’s dllamanda, of Brazil, with 
its showy large yellow flowers, climbs to the roof. 
House No. 5. The plants in this house are from desert 
regions. Especial attention is called to their fleshy stems 
or leaves which serve as storage organs for a water supply
