Manzanilla. 
A name in use for several composite weeds, the most common of which is 
Bidens leucantha. Stahl proposes to distinguish the different species according 
to the following list: : 
Manzanilla cimarrona. see Stemmodontia carnosa and Bidens lewcantha 
Manzanilla de costa. See Stemmodontia buphthalmoides, 
Manzanilla de la playa. See Stemmodontia carnosa, 
Manzanilla de monte. See Stemmodountia reticulata, 
Manzanilla del pais. See Bidens pilosa. 
Manzanilla negra. See Bidens bipinnata, 
Manzanilla trepadora. See Bidens rubifolia. 
Manzanillo. See Hippomane mancinella. 
Mapola. See Hibiscus rosa-sinensis. 
In the Philippines and Guam this name is applied to H. mutabilis, 
Mapurito. See Fagara monophylla. 
Maraga. 
Perhaps the same as “‘ maraca”’ or ** matraca;"’ applied at Catanio to a species 
of Canna. 
Marafion. See Anacardium occidentale, 
Maranta arundinacea. ARROWROOT. 
Family Marantaceae; an herbaceous plant with tubers from which arrowroot 
is extracted. Said to be called arrowroot from its property of counteracting the 
poison put on arrow tips by the natives and other acrid poison, as that of spiders. 
Called touola by the natives of Jamaica. 
The following recommendations are from Captain Hansard: 
‘‘ Blevation not important; rows 3 feet (90 centimeters) apart, 12 inches (30 cen- 
timeters) ina row. Cut off flowers to throw strength into the tubers. Plant in 
April or early May; returns will be had in a little less than twelve months. Twenty 
per cent starch may sometimes be secured, Crop seven hundredweight (329 kilo- 
grams) per acre, but double this has been obtained by high cultivation. In prepara- 
tion all skin and discolored parts are removed from the rhizomes After rewash- 
ing the rhizomes are reduced to pulp in a mortar or against a revolving cylinder 
grater. Cleanness is very necessary. In St. Vincent glass-roofed houses and the 
very cleanest machinery are used.” 
Maravedi. See Myginda rhacoma and M. pallens. 
Maravilla. See Hibiseus mutabilis, Mirabilis jalapa, and Euphorbia hetero- 
phylla. 
Maray-maray. See Dalbergia ecastaphyllum. 
Marcgravia rectiflora jacquini. BrEJUCO DE PALMA. 
An indigenous trailing or climbing shrub known also as bejuco de rana.

species, but the genuine mmnbellata does not occur in Porto Rico. 
Marcgravia sintenisii. Brsuco DE PALMA. 
A species peculiar to Porto Rico and said to be very distinct from M, rectiflora. 
It is a climber and ascends large trees. Reported from the Sierra de Luquillo, 
Sierra de Naguabo, Cayey, and Adjuntas. (Urban, Add, 3: 208.) 
Marecgravia umbellata. PEGA PALMA. 
A trailing shrub clinging to trees by adventitious roots, called ‘* bejuco de 
palma,” by Bello. (Stahl, 2: 129.)
