Granadilla tree. 
In Jamaica and Cuba the names ** granadilla tree * and ** granadilla ” are applied 
to Brya ebenus, asmall leguminous tree yielding the so-called ** American ebony.” 
This species is not yet reported from Porto Rico, Captain Hansard describes the 
“oranadilla tree’? as very large, with small leaves and spreading branches. 
Nothing will grow underneath it, and it is therefore unwelcome in coffee planta- 
tions. The yellow wood is not considered of marketable value, although it will 
make fairly good boards. The specific gravity is 1.11. The * granadilla”’ fruit 
is from a vine Passiflora quadrangularis, and has nothing to do with the tree. 
Granadillo. 
A tree from all parts of the island; height, 40 to 45 feet (13 to 14 meters); diam- 
eter, 20 to 25 inches (50 to 62 centuneters). Wood, yellow, hard; specific gravity. 
0.917; used for cabinet work, (Exp. 1857.) 
This is also enumerated by Hill among trees used for dyeing and tanning. See 
also the note under Granadilla tree,

Captain Hansard states that this tree is supposed to have two distinct sexes, 
the female being hollow, while the mule is solid and is sometimes sawed into white 
narrow boards, although he has seen some I4 inches wide. Owing to the softness 
and lightness of the wood, it is used only for inside work. The tree is large. with 
parasol-shaped leaves, and the name is sometimes erroneously pronounced “yau- 
grumo.”’

Guaba. See Juga vera, 
A inost useful tree for shade of coffee; according to Captain Hansard the spe- 
cific gravity of the wood is 0.64. :

The wood is given a specific gravity of 0.63 by Captain Hansard,
