Anoda hastata. VIOLETA.

from the continent. (Stahl, 2: 59.) 
Anon. See Anona squamosa and A. dolabripetala. 
Anona dolabripetala. ANON. 
Reported from Porto Rico by Bello, but not known to Stahl, who seems to con- 
sider it somewhat doubtful. Bello’s locality was Furnias, according to Stahl, 
- but this is not so stated in Bello’s paper. This species is also given as a synonym 
of Rollinia longifolia. 
Anona montana. GUANABANO CIMARRON. 
An indigenous shrub or tree of mountain districts; not coumon. The wood is 
fibrous and of poor quality. The fruit is globose with soft spines from the mid- 
dle of round or polygonal areas. It is not edible. (Stahl, 2: 24.) 
Anona muricata. Soursop. GUANABANO. 
Family Anonaceae; a small tree. The fruit called the ‘‘ soursop ’’ is well known 
throughout the tropics. It has a rough green skin, inclosing a soft and juicy 
white pulp of an agreeable, slightly acid flavor, in which are embedded the large 
brown seeds. In the mature condition the weight may reach 2 pounds or more. 
Grosourdy (2: 387) says there are several varieties. The wood which is not 
used is soft and light-colored, and breaks with a horizontal fracture. Specific 
gravity. 0.397. 
An infusion of the leaves is said to be a remedy for dysentery. 
Anona paiustris. ALLIGATOR APPLE. CAYUR. 
An indigenous_shrub of 2 to 5 meters, affecting swampy localities. According 
to Dr. Stahl this species has astringent properties. The fruit is not edible. Bello 
calls this ** corazon cimarron”’ as well as ‘‘cayurz.’’ (Stahl, 2: 25.) 
A small tree 24 to 30 feet (8 to 10 meters) high, the trunk reaching. 10 or 12 
inches (25 to 30 centimeters) in diameter. The wood is very light and soft, 
fibrous in texture, gray or light brown somewhat tinged with green, lustrous and 
sometimes somewhat marbled, but with long exposure to the air it turns a dirty 
white. Specific gravity of the roots, 0.175. Used in the country for rafts. The 
wood from roots that have grown in bogs is extremely soft and porous, and is 
used in Cuba to sharpen razors. 
Called also ** guanabano cimarron”’ and ‘‘corcho.’’ (Grosourdy, 2: 364.) 
Anona reticulata. BULLOCK’s HEART. CORAZON. CUSTARD APPLE. 
A wild tree not very abundant, 25 to 30 feet (8 to 10 meters) high, rather dense. 
The trunk is ordinarily straight,and 10 to 14 inches (25 to 35 centimeters) in 
diameter. Furnishes a light wood, rather soft, but resistant. Fibrous in texture, 
moderately close-grained. The wood is handsome in appearance but is not used. 
(Grosourdy, 2: 377.) These dimensions are certainly much larger than any 
seen in. the island. 
The fruit is of a more regular oval shape than that of the soursop. and the 
skin is uch more nearly smooth, being marked merely with small slightly 
raised areas. The flesh is yellow, and is generally considered inferior to that of 
the soursop.
