Tabacon. 
A tree from all parts of the island; height, 40 to 45 feet (12 to 14 meters); 
diameter, 20 to 25 inches (50 to 62 centimeters). Wood, white, soft; specific gray- 
ity. 0.477; used in building houses. (Exp. 1857.) (Grosourdy, 2: 414.) 
~Tabacon afelpado. See Solanum verbascifolium. 
Tabacon aspero. See Solanum asperum. 
Tabaiba. See Plumeria alba.: 
Tabamuco. 
This may be only another way of spelling Tabonuco. It grows to be a large 
tree, with coarse wood, which is hard to work and very long in drying; generally 
used for timber, also in constructing road canoes, or ‘‘ stone boats,’’ for hauling 
in the hills. It exudes a resinous substance used to make torches. Captain Han- 
sard gives its specific gravity as 0.66. 
Tabebuia rigida. Rosie. 
Family Bignoniaceae; a fine tree, 20 meters high, recently described from the 
Luquillo mountains. (Urban, 1: 404.) 
Tabebuia schumanniana. ROBLE COLORADO. 
A species recently discovered near Utuado and claimed by its describer to be 
one of the most beautiful of the indigenous trees of the island. It attains a height 
of from 10 to 15 meters and has blood-red flowers about an inch long. (Urban, 
Symb. 1: 404.) 
Tabeiba. See Maba sintenisii, Plumeria krugii, and P. portoricensis. 
Tabernaemontana citrifolia. PEGOGE. 
Family Apocynaceae; a wild tree, 3 meters high; grows in the mountains, 
flowering in the spring. Found in the Antilles and Mexico. Reported from the 
mountains of Luquillo. (Stahl, 6: 71.) 
Some species of Tabernaemontana have been reported as producing rubber, par- 
ticularly T. crassa,an Africantree. It has not been found possible, however, to coag- 
ulate the latex into serviceable rubber; it forms instead an extremely sticky gum. 
Tabloncillo. See Dipholis montana. 
A tree from the interior of the island; height, 40 to 45 feet (12 to 14 meters); 
diameter, 30 to 35 inches (45 to 62 centimeters). Wood, white, hard; specific 
gravity, 0.837; used in building houses. (Exp. 1857.) (Grosourdy, 2: 414.) 
Tabanuco. See Dacryodes hexandra. 
A tree from theinterior part of the island; height, 40 to 45 feet (12 to 14 meters); 
diameter, 35 to 40 inches (87 to 100 centimeters). Wood, white, rather hard; 
specific gravity, 0.671; used for lumber and resin. (Exp. 1857.) 
Tachuelo. See Pictetia aristata, also note under ‘‘ tochullo.’’ 
A wild tree abundant in the mountains, 40 feet (12 meters) in height, with a 
trunk reaching 10 or 12 inches (25 or 30 centimeters) in diameter. Furnishes a 
very hard, yellow wood that is very strong and durable. Used for shingles, 
fences, shelving, etc. When the tree is old it is burned, the wood becoming 
so hard as to resist all woodworking tools. (Grosourdy, 2: 414.) 
Tachullo. 
A tree from the interior part of the island; height, 40 to 45 feet (12 to 14 
meters); diameter, 9 to 10 inches (22 to 25 centimeters). Wood, yellowish, hard; 
specific gravity, 0.945; used for cabinetwork. (Exp. 1857.) 
This is apparently the same as ‘‘ tachuelo.”’ 
Tachulo blanco. 
Captain Hansard gives a specific gravity of 1.12 for this wood. 
Tafetan. See Palicourea barbinervis.
