116 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Cipil. 
A tree from the interior of the island; height 45 to 50 feet (13 to 15 meters), 
diameter 12 to 15 inches (30 to 37 centimeters). Wood white, very hard; specific 
gravity, 0.960; used in boat building. Also called ** pino.”’ (Exp. 1857.) 
Ciralillo. See Meliosma obtusifolia, 
Cirila. See Cyrilla antillana, 
Ciruela del pais. See Spondias purpurea, 
Cissampelos microcarpa. BEJUCO DE MONA, 
Reported by Bello from the western part of the island, 
Cissampelos pareira. BrJucoO DE MONA, 
Family Menispermaceae; an annual herb, The “ pareira brava” of the phar- 
macopoeia is a product of this plant; said to be an antidote for poison, and valua- 
ble in medicine. (Stahl, 2: 31.) 
Cissus acida. See Vitis acida. 
Cissus sicyoides. See Vitis sicyoides. 
Cissus trifoliata. See Vitis trifoliata. 
Citharexylum quadrangulare. PE&NDULO COLORADO, Puatté XXVIL 
Family Verbenaceae; a tree 20 to 60 feet (6 to 18 meters) high, with red wood; 
useful for furniture and building. Found in mountain districts. Sintenis’ speci- 
men from Cayey (no. 2321) has the leaves broader and more nearly elliptical and 
may be distinct from his 3723. Bello gives the common names ** pendola”’ and 
‘palo de guitarra.’’ (Stahl, 6: 211.) 
Grosourdy (2: 409), under the native name ** péndula,”’ describes this species 
as a wild tree reaching 50 feet (15 meters) in height, with a moderately straight 
trunk 18 inches (45 centimeters) in diameter. Furnishes a rather strong, straw- 
colored wood that breaks with an oblique fracture. Itis used for beams, windows, 
doors, etc. The natives make their guitars of this wood. Specific gravity, 0.753 
and 0.722. 
Citron. See Citrus medica. . 
Citrullus vulgaris. WATERMELON. SANpDiA. PATILLA, 
Watermelons seldom reach marketable quality in humid tropical countries. 
A few were seen in the market of San Juan, but none of them would have been 
considered fit to eat in the United States. Watermelon growing is scarcely to 
be recommended as a profitable business in Porto Rico, though with properly 
selected conditions and careful cultivation fairly good fruit can probably be 
raised, as reported by one of the Department’s correspondents. Muskimelons will 
probably succeed somewhat better. 
Citrus. 
Grosourdy (2: 3894) says of the lemon and orange that they furnish a wood 
very strong, flexible, compact, and of good durability and resistance. It is, how- 
ever, more an object of curiosity than utility, although it is used for moldings and 
inlaid work of fine furniture. The military authorities of San Juan use it for the 
handles of tools. He gives the specific gravity of lemon as 0.833 and that of the 
orange as 0.815, 
Citrus aurantium. SWEET ORANGE, CHINA. 
**China’’ is the name under which the common sweet orange is known in Porto 
Rico, the Spanish name for the orange, “*naranja,”” being applied to the sour 
orange. 
This fruit may be distinguished from the sour orange not only by the taste but 
by the smoother and more even surface, the thinner and more closely fitting rind, 
and the solid center. 
Until recently the orange in Porto Rico has been propagated only by seeds, and
