106 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Caracolillo listado. 
A tree from the western part of the island; height. 15 to 20 feet (5 or 6 meters); 
diameter, 30 to 35 inches (75 to 90 centimeters). Wood yellow, streaked; specific 
gravity, 0.952; used in making furniture. (Exp. 1857.) 
Cardenala azul. See Lobelia cliffortiana. 
Cardiospermum halicacabum. Fanrouiros. 
Family Sapindaceae; an annual, climbing herb, known as heart seed, winter 
cherry, and heart pea. At Rio Piedras a specimen (no, 1004) was obtained, under 
the name ‘* bombija.’’ (Stahl, 2: 153.) 
Cardo. See Caurduus mevicanus. 
Cardosanto. See Argemone mexicana. 
Carduus mexicanus. Carbo.

Cariaquito blanco. See Melanthera deltoidea, 
Carica papaya. See Papaw. Payaya. 
Family in Porto Rico commonly called ‘‘ lechosa,’’ meaning ‘‘ milky,’ or 
‘‘napaya lechosa.’’ This useful species is everywhere cultivated at low eleva- 
tions; it has also escaped from cultivation and now grows spontaneously in waste 
places. 
Caro. See Vitis sicyoides. 
According to the list of the Exposition of 1857, there are two trees of this name, 
both occurring in all parts of the island. One has a height of 80 to 35 feet (9 to 
11 meters): diameter 19 to 20 inches (48 to 50 centimeters). Wood light-colored, 
hard; specific gravity, 0.980; used in building houses. Also called ** chupagallo.”’ 
The other has a height of 85 to 40 feet (10 to 12 meters); diameter, 6 to 8 inches 
(15 to 20 centimeters). Wood yellow, hard; specific gravity, 0.873; used in mak-

Carubio. See Fugara monophylla, 
Caryocar nuciferum. Souari NUT. 
A tree belonging to the family Caryocaraceae. It is a native of Guiana, 
but has been cultivated in several of the West Indies. Three other species of 
Caryocar—C. glabrinm, C. barbinerve, and C, tutermedinm—have been reported as 
growing in Martinique, but all are probably introduced. 
Both the flowers and the fruit are very large. the latter several inches in diam- 
eter and inclosing from 2to4 hard-shelled nuts, the size of a hen’s egg, but some- 
what kidney-shaped, and with rounded warts on the outside. These are described 
as having a very pleasant flavor and also as yielding an oil to pressure. The tree 
attains a height of 100 feet (30 meters) or more, and the timber is of good quality, 
and very durable. Its chief use has been in the line of shipbuilding. 
In his ** Tropische Agrikultur’’ Semler expresses a very high opinion of the 
valuable qualities of the souari nut, considering it in fact the finest of all nuts, 
and the one most likely to prove successful and remunerative in culture. The 
taste is said to be similar to the almond, but sweeter, and the small quantities 
sent to the European markets have found ready sale at good prices. Successful
