386 NATURAL HISTORY OF PLANTS. 



In the "West Indies the fruits of Sapindus Saponaria^ (fig. 353) are 

 especially used for -washing; in Guiana, those of S. aborescens^ (fl.g. 

 351, 352) and frutescens;^ S. rigida'^ in Bourbon and Mauritius; 

 S. senegalensis ^ in tropical western Africa ; and 8. divaricatus ® in 

 Brazil. The pericarp of the latter is thin, translucid, filled with a 

 viscid juice. Its seeds, globular, black, and smooth, are used, like 

 those of many species of the genus, to make necklaces. Few species 

 have an edible pericarp, because there is often a smell and taste of tur- 

 pentine. Those of S. emarginatus ^ are eaten, it is said, in Georgia 

 and Carolina, and the negroes of the Senegal seek that of 8. senegal- 

 ensis which has a vinous and sugary flavour. The fruits of 8. escu- 

 lentus ^ in 'Brazil and those of 8. fruticosus in Malabar are also 

 edible. The bark and root of several species,^ especially of 8. 

 8aponaria are, notwithstanding their acerbity, used as astringent and 

 tonic-bitter remedies. The tincture of the fruit has been recom- 

 mended for chlorosis, and the pulverised seeds are used for poison- 

 ing rivers. The Euphorias have quite a different kind of utility 

 in the tropical countries of the old world. The best known and 

 most frequently cultivated is E. Longana ^° (fi,g. 354, 355), whose 

 seed is surrounded by a sapid, yellowish fleshy aril, sweetish and 

 acidulated, sought for as an aliment, refreshing, and dried like plums 

 to keep them during the bad season. It has unfortunately a vinous 

 taste and is smaller and not so good as that of Nephelium Litchi " 

 (fig. 356-358), which is red, pulpy, acidulate and sweetish, with an
