944 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Spigelia anthelmia. YERBA DE LOMBRICES. 
Family Loganiaceae; an herbaceou: annual, 30 centimeters high, found in culti- 
vated fields. This plant has strong narcotic and anthelminthic properties. Bello 
records the common name ‘‘lombricera.’’ (Stahl, 5: 54.) 
Spilanthes uliginosa. See Spilanthes acmella. 
Spondias dulcis. 
Family Anacardiaceae; a tree cultivated for its edible fruits throughout the 
Tropics; reported from Penuelas. 
Spondias lutea. HoG PLUM. JOBO. 
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 1} 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 Spondias 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.) 
Spondias purpurea. CIRUELA DEL PAIS. 
A tree or shrub 4 to 5 meters high, introduced from South America. Cultivated 
in gardens for its agreeable, deep purplish-red fruits, which are considered better 
flavored than those of Spondias lutea. (Stahl, 4: 57.) 
Stachytarpha. See Valerianodes. 
Stachytarpheta. See Valerianodes. 
Stahlia maritima. CoBano. 
Also called ‘* polisandro.’’ Described as a magnificent, widely branching, 
indigenous, leguminous tree, 5 to 20 meters high. known from the seashore near 
Rio Grande, Ceiba, Naguabo, Guanica, Barinas, and La Plata. (Bello, Stahl, 
Urban. ) 
Star apple. See Chrysophyllum cainito.

Stemmodontia carnosa. MANZANILLA DE LA PLAYA. 
A common herbaceous annual weed preferring sandy soils and open grounds. 
It was very common about Santurce, where it was called ‘‘ manzanilla cimarrona,”’ 
(Stahl, 5:135, as Wedelia carnosa.) 
Stemmodontia lanceolata. 
Reported from Guanica. 
Stemmodontia reticulata. MANZANILLA DE MONTE. 
A woody biennial, 80 centimeters high, found in waste places in the foothills. 
(Stahl, 5: 136, as Wedelia reticulata.)
