(Coffea bengalensis), Madagascar coffee (Coffea madagas- 
cariensis), tamarind (Tamarindus indica), wild clove 
(Pimenta acris), Paraguay tea (Ilex paraguensis), and 
various species of pepper (Piper). On the side stages several 
interesting notiginel lants may be seen, such as the 
quinine (Cinchona officinalis) and strychnine (Strychnos 
nus-vomica). 2 
In house 9 the plants that yield perfumes are arranged 
on the south side, one of which, the patchouli plant (Pogoste- 
mon Heyneanus) is used by the Hindoos for perfuming 
cashmere shawls. The middle stage is occupied by economic 
plants used in various industries. 
House 8 contains the collections of oils, gums and resins, 
including the oil of cloves (Pimenta acris), olive oil (Olea 
europea), camphor oil (Cinnamomum Camphora), tea oil 
(Camellia Sesanqua), gum arabic (Acacia arabica), kutteeria 
gum (Acacia Lupdekien). anime resin (Hymenexa Cour- 
baril). On the side stage a few Mexican rondeletias are in 
bloom, their pink flowers somewhat resembling the common 
lantana. Entering the agave house a small group of the 
“Crown of Thorns” (Euphorbia splendens) will be noticed, 
their small scarlet flowers contrasting with the thorn-like 
growths. In the desert house some interesting succulent 
plants, “hen and chickens,” are on exhibition, their flowers 
varying in color from white to orange red. An unusual cactus- 
like geranium (Pelargonium echinatum), native of South 
Africa, is blooming at the present time.

bright scarlet, brush-like flowers. ie close examination will 
reveal the fact that it is the mass of filamentary stamens 
and pistils which gives the bright color, and not the sepals, 
which are insignificant and of a pale green color. Acacia 
spadicigera, one of the mymecophilus plants, is producing 
its new growth, including the bihorn-like thorns. These 
thorns are frequented by ants in the plant’s native habitat of 
Brazil, and the association is supposed: to be of mutual 
benefit. 
Bromeliad House. Aechmea Barleei-and several species 
of Tillandsia have flowered, the bright-colored bracts at once 
attracting attention. The vanilla beans are ripening rapidly 
and give off an abundance of perfume.
