Delgado describes the various species of trees in the Philippines in the first six treatises of the first part of the fourth book of Historia general de Filipinas (Manila, 1892).  He mentions by name more than seventy trees grown on the level plains and near the shores; more than forty fruit-trees; more than twenty-five species grown in the mountains; sixteen that actually grow in the water; and many kinds of palms.  See also Gazetteer of the Philippine Islands (Washington, 1902), pp. 85-95, and Buzeta and Bravo’s Diccionario (Madrid, 1850), i, pp. 29-36.

[73] Sanctor is called santol (Sandoricum indicum—­Cavanilles), in Delgado (ut supra, note 71).  The tree resembles a walnut-tree.  Its leaves are rounded and as large as the palm of the hand, and are dark green in color.  Excellent preserves are made from the fruit, which was also eaten raw by the Indians.  The leaves of the tree have medicinal properties and were used as poultices. Mabolo (Diospyros discolor—­Willd.) signifies in Tagal a thing or fruit enclosed in a soft covering.  The tree is not very high.  The leaves are large, and incline to a red color when old.  The fruit is red and as large as a medium-sized quince, and has several large stones.  The inside of the fruit is white, and is sweet and firm, and fragrant, but not very digestible.  The wood resembles ebony, is very lustrous, and is esteemed for its solidity and hardness.  The nanca [nangka, nangca; translated by Stanley, jack-fruit] (Artocarpus integrifolia—­Willd.), was taken to the Philippines from India, where it was called yaca.  The tree is large and wide-spreading, and has long narrow leaves.  It bears fruit not only on the branches, but on the trunk and roots.  The fruit is gathered when ripe, at which time it exhales an aromatic odor.  On opening it a yellowish or whitish meat is found, which is not edible.  But in this are found certain yellow stones, with a little kernel inside resembling a large bean; this is sweet, like the date, but has a much stronger odor.  It is indigestible, and when eaten should be well masticated.  The shells are used in cooking and resemble chestnuts.  The wood is yellow, solid, and especially useful in making certain musical instruments.  Buzeta and Bravo (Diccionario, i, p. 35) say that there are more than fifty-seven species of bananas in the Philippines.

[74] Pile (Canarium commune—­Linn.).  Delgado (ut supra) says that this was one of the most notable and useful fruits of the islands.  It was generally confined to mountainous regions and grew wild.  The natives used the fruit and extracted a white pitch from the tree.  The fruit has a strong, hard shell.  The fruit itself resembles an almond, both in shape and taste, although it is larger.  The tree is very high, straight, and wide-spreading.  Its leaves are larger than those of the almond-tree.
