COOK AND COLLINS—ECONOMIC PLANTS OF PORTO RICO. 193 
Moca amarilla. 
A tree from the northeastern part of the island; height, 25 to 30 feet (7 to 9 
meters); diameter, 15 to 20 inches (37 to 50 centimeters). Wood .ed, hard; spe- 
cific gravity, 0.904: used for cabinetwork. (Exp. 1857.) 
Moca negra. 
A tree from the eastern part of the island; height, 30 to 35 feet (9 to 11 meters); 
diameter, 15 to 20 inches (37 to 50 centimeters). Wood dark, hard; specific gravity, 
0.811; used for cabinetwork. (Exp. 1857.) 
Molinillo. See Leonotis nepetaefolia. 
Momordica. 
A genus of Cucurbitaceae. The species are graceful and delicate climbing 
vines, bearing rather small edible fruits. 
Momordica charantia. CUNDEAMOR. PLATE XLVI. 
This species is supposed to be the most common and generally distributed, per- 
haps because confused with M. zeylanica, which in Porto Rico, at least, is much 
more abundant. The present species was not noticed by us, but has been collected 
by Sintenis at Fajardo. It differs from M. zeylanica in the much larger and 
longer fruit, the surface of which is irregularly covered with rounded warts and 
tubercles. The seeds are also much larger, and the leaves have 4% very different 
cut, as may be seen by reference to the figure. 
Both species are sometimes called ‘* balsam apple.” 
Momordica zeylanica. CUNDEAMOR. 
This species is one of the commonest and most widely distributed plants in 
Porto Rico, climbing over fences and other vegetation in open places. Many 
botanists have confused it with MW. charantia, but it may be recognized readily by 
the different leaf pattern, the small oval fruits with rows of sharp spines, and the 
small seeds. 
Monkey apple. See Anona palustris. 
Monodora myristica. CALABASH NUTMEG. 
Also called ** American nutmeg’ and ‘* Jamaica nutmeg.’* An anonaceous tree, 
supposed to have been introduced from West Africa. Its occurrence in Porto 
Rico seems doubtful, a species of Nectandra having, in some cases at least. been 
mistaken for it. 
Grosourdy (2: 382) reports it from all parts of the island, and gives the height 
of the tree as reaching 25 or 30 feet (8 or 9 meters), with a diameter of 10 inches 
(25 centimeters). The wood, he says, is yellow, rather strong, but without appli- 
cation. His identification was perhaps based on the native name *‘ nuez moscada 
del pais,”’ in which case the description probably refers to a species of Nectandra. 
Mora. See Chlorophora tinctoria. 
Hill & Sudworth (p. 27) describe a wood of this name as follows: 
Color, bright orange brown, probably darkening with age and exposure. 
Marked on the radical section with parallel light and dark streaks. Large ducts 
arranged in wavy. irregular lines; lines also irregularly broken into crescent-shaped 
groups. Medullary rays distinct, rather coarse. Radically cut and polished sur- 
face satiny. Similar in general appearance to osage orange. Largely used for 
fellies. 
Hansard gives the specific gravity as 0.86, Perhaps the same as ‘** moral.” 
Mora amarilla. 
A tree from the eastern partof the island; height, 30 to 35 feet (9 to 11 meters); 
diameter, 15 to 20 inches (37 to 50 centimeters). Wood, yellowish, hard; specific 
gravity, 0.807; used for cabinetmaking. (Exp. 1857.) 
Moradilla azul. See Salvia occidentalis, 
Moradilla encarnada. See Salvia coccinea,
