A tree from all partsof the island; height, 25 to 30 feet (7.5 to 9 meters); diam- 
eter, 12 to 15 inches. Wood, light, soft; specific gravity, 0.688; not used. 
(Exp. 1857.) 
Captain Hansard gives this wood a specific gravity of 0.44. 
Guanabano cimarron. See Anona montana and A. palustris. 
Guanavano. See Anona muricata. 
A less correct form of ‘‘ guanabano.”’ 
Guanaguao.

diameter, 60 to 65 inches (150 to 160 centimeters). Wood flesh-colored, soft: 
specific gravity, 0.741; not used. (Exp. 1857.) 
Guano. See Ochroma lagopus. 
Silk-cotton tree with long, fluffy pods sold in market: grows profusely in British 
islands. 
A tree from all parts of the island; height, 25 to 30 feet (7.5 to 9 meters); diam- 
eter, 18 to 20 inches (45 to 50 centimeters). Wood, yellow very soft: specific 
gravity, 0.231; little used. (Exp. 1857.) 
Guansa. 
A tree from all parts of the island; height, 35 to 40 feet (11 to 12 meters); diam- 
eter, 10 to 12 inches (25 to 30 centimeters). Wood ash-colored, rather hard; 
specific gravity, 0.729; not used. (Exp. 1857.) 
Guao. See Comocladia, 
According to Engler this name is applied to Comocladia tlicifolia, an anacardi- 
aceous tree, also known as ‘‘carrasco”’’ in Porto Rico and other West Indian 
islands. Hill’s reference (p. 34) is evidently an error for ** guano,’ the popular 
name of Ochroma lagopus, the West Indian cork-wood tree. which furnishes a 
downy fiber. 
Guara. See Cupania americana. 
A tree from all parts of the island; height, 30 to 35 feet (9 to 11 meters): diam- 
eter, 10 to 12 inches (25 to 80 centimeters). Wood white, soft; specific gravity, 
0.596; not used. (Exp. 1857.) , 
Captain Hansard gives a specific gravity of 0.70. 
Guaraguadillo. See Guarea humilis. 
Guaraguao. See Guarea swartzii, G. trichilioides, and Trichilia spondiodes. 
A tree occasionally found, but not plentiful, in the mountains of the northeastern 
part of the island. The wood isred and makes good boards, similar to mahogany; 
specific gravity, 0.69 (Hansard). 
Light reddish brown, streaked with lighter and darker shades. Large ducts 
numerous, occurring singly or in irregular loose groups of two to four. Medul- 
lary rays numerous, but very indistinct. An exceedingly cross-grained, porous 
wood, somewhat similar in color to cedro, Suitable for a cabinet wood. (Hill 
and Sudworth, p. 29.) 
Grosourdy (2: 887) refers this variety to both Guarea trichilioides and 
Trichilia moseata and describes it as an abundant wild tree, 70 feet (21 meters) in 
height, whose long, straight trunk reaches a diameter of 6 or 64 feet (about 2 
meters). Itfurnishes a rather hard wood of good weight. dense and close-grained., 
dark flesh-colored, and breaking with an oblique fracture. It is much appreciated 
for the construction of strong wagons and carriages and farm implements and in 
many branches of carpentry work. 
Guaraguao cimarron. See Trichilia havanensis,
