248 XXVIII. GRAMINEZ, [Zragrostis 
Sangildld, sometimes pronounced Sangalslé (plural Massangrala), is 
the name which the negroes who inhabit the maritime territory of 
Angola give to a kind of hay-grass, very plentiful along the coast, 
which on account of its mode of growth becomes very dangerous to 
travellers, because the stems are habitually curved in the form of bows, 
rooting at their extremities and constituting at intervals natural snares 
which cause the unwary to fall to the ground. 
This: grass is so stiff, and its stems have so hard a fibre, that the 
negroes of Angola use it almost exclusively for tooth-brushes ; the 
negresses in returning to their huts from water-carrying or other 
occupations are seen almost always busy polishing their teeth with 
Sangalala.
