stains in silks. _G. gummifera_ yields a resin something like
Elemi.

217. GASTROLOBIUM BILOBUM.--A leguminous plant, having poisonous
properties. In western Australia, where it is a native, farmers
often lose their cattle through their eating the foliage. Cats and
dogs that eat the flesh of these poisoned cattle are also
poisoned. _G. obtusum_ and _G. spinosum_ possess similar
properties.

218. GENIPA AMERICANA.--This belongs to the cinchona family, and
produces the fruit called genipap or marmalade box. It is about
the size of an orange, and has an agreeable flavor. The juice of
the fruit yields a bluish-black dye, called Canito or Lana-dye.
This color is very permanent, and is much used by Indians in South
America.

219. GEONOMA SCHOTTIANA.--A pretty Brazilian palm; the leaves are used
for thatching huts, and other parts of the plant are utilized.

220. GOUANIA DOMINGENSIS.--A plant of the buckthorn family, known in
Jamaica as Chaw-Stick, on account of its thin branches being
chewed as an agreeable stomachic. Tooth brushes are made by

stems. It is said to possess febrifugal properties, and owing to
its pleasant bitter taste it is used for flavoring cooling
beverages.

considerable economic value. This particular species yields a
profusion of small red fruits which are used for flavoring drinks,
having a pleasant acid flavor. The fibrous inner bark is employed
by the natives for making fishing nets, ropes, twine, and for
other similar purposes.

223. GRIAS CAULIFLORA.--The anchovy pear of Jamaica. The fruit is
pickled and eaten like the mango, having a similar taste.

224. GUAIACUM OFFICINALE.--The wood of this tree is called Lignum Vitae.
