Spigelia anthelmia. YERBA DE LOMBRICES. 
Family Loganiaceae; an herbaceouw annual, 30 centimeters high, found in culti- 
rated fields. This plant has strong narcotic and anthelminthic properties. Bello 
records the common name “ lombricera.” (Stahl, 5: 54.) 
Spilanthes uliginosa. See Spilanuthes cemella, 
Spondias dulcis. 
Family Anacardiaceae; a tree cultivated for its edible fruits throughout the 
Tropics; reported from Penuelas. 
Spondias lutea. How plum. Joo, 
Family Anacardiaceae; one of the most common trees in Porto Rico, planted 
extensively for shade and for the sake of its edible fruits. It grows readily from 
large cuttings, and with Bursera simaruba, the “ almacigo,”” is preferred for 
stakes and fence posts, which are durable because they take root and remain 
alive, The fruits are oval and attain a length of 14 inches. The skin is very thin 
and incloses a pleasantly acid pulp surrounding the nut-like seed. The tree attains 
a height of 40 feet (42 meters) or more. and a diameter of from 1 to 2 feet (30 to 
60 centimeters), but the wood is light and soft (specific gravity 0.457), and is 
very little used except in the way explained above. The fruits of this species are 
yellow, and are said to be inferior to those of Spoudias purpurea, Hog plum” 
is a Jamaica name and does not, as might appear, involve any reflection on the 
quality of the fruit, but refers to the fact that hogs are extremely fond of this 
fruit, on which they fatten rapidly. 
Grosourdy gives the specific gravity of the wood as 0.508 and says that it is 
strong and elastic, yellowish-brown in color, so marked as to give a pleasing 
appearance, (Grosourdy, 2: 393.)
