COOK AND COLLINS—ECONOMIC PLANTS OF PORTO RICO. 207 
Oreodoxa regia. See Roystonea regia. 
Oreopanax capitatum. PALO CACHUMBA. 
Family Araliaceae; a shrub, 4 meters high, on hills near Coamo. (Stahl, 
4: 198, as Aciadophyllum capitatum. ) 
Ormosia dasycarpa. PALO DE MATOS. 
Family Viciaceae; a tree, 10 meters high,in mountains. Wood of good quality. 
(Stahl, 3: 99.) 
Ormosia krugii. PALO DE MATOS. 
A leguminous tree of 10 to 25 meters, known only from Porto Rico and Domin- 
ica. Specimens in the National Herbarium, collected by Sintenis, near Juncos, 
show the wood to be light and pithy. The leaves are very large, about 20 inches 
(50 centimeters) long, and the pods are brown and leathery, containing from one to 
three red and black beans. Another specimen from Mount Francis, Sierra de las 
Piedras, has much smaller, closely veined leaves, more densely pubescent on the 
under side. 
Orosne. See Polygala paniculata. 
Orozuz. See Scoparia dulcis. 
Ortegon. See Coccolobis rugosa. 
Ortela. See Marsypianthes hyptoides. 
Ortiga. 
An ingredient for a refreshing drink, on sale by a herb dealer in the market of 
Ponce. Said to be derived from a tree; perhaps ortegon. 
Oryza sativa. RICE. 
Very little rice is now grown in Porto Rico, and this is planted without irriga- 
tion in ordinary fields, such as we might use for wheat. A considerable quantity 
is, however, imported from the Hast Indies, largely by way of Germany and 
Spain. The question has been raised as to whether the low grade and broken rice 
produced in our Southern States might not be advantageously utilized in Porto 
Rico, and there seems to be every probability that considerable quantities would 
find a ready market. In the United States rice is seldom treated as a staple article 
of food, but is looked upon merely as an accessory dish or dessert, for which 
fancy prices are readily paid. This, however, excludes from the market all of the 
broken kernels and lower grades. The food value of these is, however, quite as 
great as that of the higher-priced article, and there is a large class in Porto Rico 
which might be expected to avail itself of a cheap but wholesome article of this 
kind. 
Ossea fascicularis. See Henriettella fascicularis. 
Otaga. See Opuntia decumbens. 
Otaheite apple. See Hugenia malaccensis. 
Otaheite gooseberry. See Cicca disticha.
