Cassia Fistula, or GOLDEN SHOWER, a tree from India which gets its 
name from its long racemes of golden flowers. This species, which 
furnishes the cassia pods used in medicine, has been widely introduced 
into the West Indies and other tropical sections. Senna leaves are 
from a closely related species. 
Cassia grandis, or PINK SHOWER, a native of tropical America, with 
masses of pink flowers, planted as an ornamental. 
Castilloa elastica, a native of Central America, belongs to the Moraceae, 
the family to which our mulberry belongs. The juice, secured by tap- 
ping the trees, thickens when exposed to the air, and becomes the raw 
rubber of commerce. This species has been extensively introduced 
into Ceylon, India, and other tropical countries. 
Casuarina equisetifolia. or BEEFWOoD, is a native of the Old World 
tropics that belongs to the Casuarinaceae, a family with no local rep- 
resentatives. This quick-growing tree is grown for its odd appearance 
and for its timber value. Its very red wood is hard and durable. 
The tree is much used in warm climates to hold the sands of seacoasts. 
The collection includes, also, four related species. 
Catha edulis, or ARABIAN TEA, is an evergreen shrub from Arabia 
that belongs to the Celastraceae, the family to which our climbing 
bitter-sweet belongs. The leaves, which possess sustaining and re- 
cuperative properties, are chewed by the Arabs or made into tea. 
Cecropia palmata is a member of the Moraceae, the family to which our 
mulberry belongs. It is of especial interest to scientists because of 
the relation that exists between it and the ants that live in its hollow 
stems. 
Cedrella odorata, or West INDIAN CEDAR, is a native of the West Indies 
that belongs to the Meliaceae, the family to which mahogany belongs. 
The species grows to be a handsome large tree, valued as a shade tree 
and as a source of the cedar wood of commerce—wood much used in 
furniture making and in making cigar boxes. 
Ceratonia Siliqua, or Caros, or St. JOHN’s BREAD, is a native of the 
Mediterranean region that belongs to the Leguminosae, or Pulse 
family. This is one of the mcst important economic plants in exist- 
ence, and our Government is much interested in having it established 
in the United States. It does well in California, and could be grown 
throughout our southern states. The tree is a handsome one that 
resembles the honey locust in appearance. One tree may bear as 
many as 450 pounds of pods each year. It is claimed the carob tree 
produces more food material per acre than the best alfalfa. The pods 
are eaten by both man and beast. They form an important ingredient 
in many patent cattle foods, and are today an important export of 
Palestine, Syria, and Cyrus. They are used as the chief food for cattle 
and swine in many lands. They are the ‘‘husks’’ upon which the prodi- 
gal son dined—not such poor fare, according to the notions of the 
children who buy them at the drugstores as sweets. They are sup- 
posed to be the “‘locusts’’ that St. John lived on in the wilderness, hence 
the name of St. John’s Bread. The pods have some use in the manu-
