COOK AND COLLINS—ECONOMIC PLANTS OF PORTO RICO. 115 
grained, but not very lasting. Specific gravity, 0.577. Also called ‘‘ cerezo de la 
tierra.’’ (Grosourdy, 2: 376.) 
Cicca disticha is given asasynonym of Phyllanthus distichus, an Indian species. 
Cicer arietinum. GARBANZO. 
The extensive use of garbanzos or chick-peas by the Porto Ricans, and doubt- 
less also by other Spanish-Americans, suggests the desirability of cultivating them 
in the United States for export to these tropical countries. Moreover, they are 
undoubtedly a palatable and nutritious dish which, if properly introduced, should 
find a place on the American table. 
Wecould not learn that any ‘‘ garbanzos’’ were grown in the island or that any 
experiments in this direction were ever tried. 
Cidron. See Lippia nodiflora. 
Cieneguillo. See Daphnopsis philippiana, Eugenia confusa, Comidesia lin- 
deniana and Myrcia deflexa. 
Cienigilla. 
A tree with very hard white wood; grows to no great size; similar to ash; not 
uncommon in the mountains. (Hansard.) 
Cieniguillo. See Myrcia ferruginea and M. deflexa 
Doubtless the same name as cieneguillo. 
Cinchona. QUININE. 
Experiments have been tried with cinchona in Jamaica, but the market is now 
well supplied by Java and the British West Indies, so that planting in Porto Rico 
does not seem advisable from the commercial standpoint. 
Cinnamodendron macranthum. CHUPAGALLO. 
A tree belonging to the family Canellaceae; 10 meters high, with greenish 
white, orange-perfumed flowers. From Sierra de Luquillo. (Urban, Add. 1: 9.) 
Cinnamomum camphora. CAMPHOR TREE. 
The true camphor tree of Japan and China has been successfully planted in 
California and in the warmer parts of our Gulf States, since it is able to withstand 
light frosts. It makes a beautiful and in every way desirable shade tree in adai- 
tion to its value for the extraction\of camphor, for which some have calculated 
that its culture would be a paying business. It seems entirely probable that the 
camphor tree would grow well in Porto Rico,and the conditions are probably 
favorable for the production of the gum, in which respect the culture of camphor 
in North Africa has failed, perhaps owing to the too great heat and dryness of the 
climate. 
The present species is not the only one yielding camphor; Blwmea balsamifera, 
a composite herb native in China, and Dryobalanops aromatica, a large tree of 
the family Dipterocarpaceae, native in Borneo and neighboring islands, also yield 
substances closely similar to camphor, and even more highly valued. 
Cinnamomum zeylanicum. CINNAMON. 
The cinnamon tree is native in Ceylon and other parts of the East Indies, and 
has been introduced into the American tropics, though not known to have reached 
Porto Rico. It might thrive in a few situations on the south side of the island, 
but a dry, sandy soil is considered necessary for the production of bark of good 
quality,and Porto Rico has little land of that kind. Cinnamomum cassia and 
other species of the genus are more hardy and produce commercial barks used as 
substitutes and adulterants of the true cinnamon, to which they are inferior. 
Cinnamon. See Cinnamomum. 
Cinnamon, wild. See Canella alba and Amomis caryophyllata. 
Cionandra racemosa. See Cayaponia racemosa.
