110 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Cebada. See Hordeum, 
Cebolla. See Allium cepa. 
Ceboruquillo. See Thouinia tomentosa, 
A tree from the western part of the island; height 70 to 80 feet (21 to 24 meters); 
diameter 10 to 12 inches (25 to 28 centimeters). Wood, light-colored, hard; specific 
gravity, 0.857; used for packing boxes. (Exp. 1857.) 
Cecropia obtusa. 
Collected by Sintenis near Bayamon. 
Cecropia peltata. TRUMPET TREE. YAGRUMO HEMBRA. 
The name ** yagrumo hembra”’ has reference to the fact that this tree is popu- 
larly supposed to be the female of Didymopanaxe morototoni, called ‘* yagrumo 
macho.’ The stems of the present species are hollow; it grows very rapidly and 
although attaining a height of 50 feet (15 meters) with a diameter of a foot (25 
millimeters) or more, it seems rather like an overgrown herb than a real tree. 
The trunk and branches are partitioned at the nodes or former points of attach- 
ment of the very large peltately divided leaves. 
The juice of Cecropia contains india rubber, but the quantity obtainable by the 
usual process of tapping is smalland the product has not become of commercial 
importance, 
Cedar. See Cedrela odorata. 
Cedrela odorata. West INDIAN CEDAR. CEDRO, 
Family Meliaceae. A large tree; wood of a brown color and fragrant odor, 
known variously as West Indian, Spanish, Jamaica, or Honduras cedar; used for 
furniture, moth-proof chests, shingles, canoes, and other articles that have to 
withstand the weather; also for cigar boxes. (Stahl, 2: 168.) 
Color, pale reddish brown. Large ducts few, occurring singly, irregularly 
grouped, and scattered. Medullary rays few and indistinct. Wood fibers inter- 
laced, the wood splitting irregularly, Very similar to the mahogany of coim- 
merce. Probably Cedrela odorata, the well-known cigar-box wood of commerce. 
It is no longer abundant in Porto Rico, and is now largely imported from Santo 
Domingo, costing $150 per 1.000 feet. It still grows in Aguadilla and near Aibo- 
nito, Juana Diaz, Cayey, and Luquillo. (Hill and Sudworth. ) 
Grosourdy distinguishes three varieties of the wood-—cedro blanco, cedro hem- 
bra colorado, and cedro macho—but states that the trees are identical. 
The tree is 60, 90, or 100 feet (18, 27, or 30 meters) high, with a long straight 
trunk 4) to 6 feet (1.5 to 2 meters) or more in diameter. Planted this tree would 
be a source of wealth, and already plantations exist in Cuba, an example that 
should be followed in the other Antilles, for it not only grows with greater 
rapidity than mahogany, but is also much less delicate and will prosper in all 
localities. The tree, however, prefers a clean light soil on the tops of hills or on 
plains. It is not injured by moisture, except when the soil is submerged. It is 
propagated by seeds or cuttings, and reaches its growth in forty years. 
This precious wood of agreeable odor is very lasting. It is heavier, more com- 
pact, and darker colored than mahogany, which the variety called ** cedro macho 
much resembles: the variety known as ‘‘cedro hembra’ is much lighter, less 
compact, softer, and much lighter in color, The first-named variety is used for 
furniture, carpenter work, and the interior of houses, and for the latter is pre- 
ferred to mahogany, being softer and more easy to work, also having the advan- 
tage of never being attacked by insects. It is also used for windows, balconies, 
etc. The military authorities use it for boxes, powder vessels, ete. 
The second variety is fit for the same purposes, and is furthermore used exten- 
sively in making cigar boxes. The specific gravity is 0.474 and 0.461. (Gro- 
sourdy, 2: 874.)
