Hacana. See Lucuma multiflora. 
A tree from all parts of the island; height, 20 to 25 feet (6 to 8 meters); diame- 
ter, 8 to 10 inches. Wood white. rather hard; specific gravity, 0.924; not used. 
This is perhaps the same as ‘“‘acana’”’ and ‘‘jacana.”’ (Exp. 1857.) 
Hacanilla. See Ardisia purpurascens. 
This name was perhaps intended for ‘‘jacanillo,”’ appled to Ardisia pendula. 
Hachuelo. See Pictetia. 
** Color, rich dark yellowish-brown, with streaks and mottlings of light yellow- 
brown. Ducts minute, very numerous, occurring singly, and irregularly dif- 
fused between the medullary rays or often interrupting the rays. Medullary 
rays very numerous, indistinct. Wood fibers interlaced, but appearing rather 
straight grained on the finished surface. Valuable for cabinetwork.”’ (Hill and 
Sudworth. ) 
Hachuelo. 
An erroneous name given by Hill for the calabash tree. Crescentia cujete, which 
seems also to have been confused by him with ‘‘tachuelo’’ or Pictetia. 
Haematoxylon campechianum. Palo DE CAMPECHE. 
Family Cassiaceae; a medium-sized tree yielding the logwood of commerce. 
(Stahl, 3: 104.) ; 
A wild tree reaching 30 to 45 feet (9 to 14 meters) high, but with short trunk 
seldom attaining 6 or 9 feet (2 to 3 meters); very crooked and irregular, prolonged 
into large branches rather long and straight. The diameter of the trunk is 18 to 
24 inches (45 to 60 centimeters); of the branches 8 to 10 inches (20 to 25 centime- 
ters). The wood is very hard and heavy, compact in texture, dark purple with 
darker stripes, frequently tinted with orange, especially toward the outside, which 
is lighter, variegated with orange. Without doubt at the fall of the tree the wood 
is of one color, a reddish white, and takes on its beautiful color little by little 
after exposure to the air. Specific gravity, 0.992. 
The wood is not only used as a dye, but can be utilized in turning. (Grosourdy, 
2: 369.) 
Haemocharis portoricensis. NINO DE COTA.
