Mangachapuy (Dipterocarpus mangachapuy—Vatica apteranthera) gives logs up to 55 feet long by 20 inches square. It is very elastic and withstands the climate, when seasoned, as well as Teak. It is used in Manila for masts and decks of vessels and for all work exposed to sun and rain. It is much esteemed and in great demand by those who know its good qualities.
Macasin can be used for interior house work and floors. It is somewhat inferior to Banaba, but supplies its place when Banaba is scarce. It can be got in greater length and square than Banaba.
Malatapay (a variety of Diospyros philoshantera), veined black and red. It resembles Camagon.
Mancono is a very hard wood found in Mindanao Island; it is classed as a species of lignum-vitæ.
Narra (Pterocarpus palidus santalinus) gives logs up to 35 feet long by 26 inches square. It is the Mahogany of the Philippines, inasmuch as it is always employed in Manila in the manufacture of furniture, for notwithstanding its somewhat open grain, it polishes well, and is prettily marked. There is a variety of shades in different logs varying from straw colour to blood-red, the former being more common; all are, however, equally esteemed. It is a first-rate wood for general purposes. In the London market it is classed with the Padouk of Burmah.
Palo Maria de Playa (P. Polyandria—Calophyllum inophyllum) (Tagálog, Dangcalán), is greatly appreciated for crooks and curves, but as a rule cannot be found of suitable dimensions for large vessels. It is better than Molave for this purpose, for, due to the absence of acrid juices, iron bolts do not corrode in it. It is exceedingly tough and not so heavy as Molave.
Supa (Sindora wallichii, Benth.) gives logs up to 40 feet long by 28 inches square. It produces an oil, and is a strong wood for general purposes, polishes well and can be used advantageously for house decorations and furniture.
Tíndalo (Eperna rhomboidea) is about the same as Acle in its principal features, but not notable for resisting fire. It is useful for general purposes, and in particular for decorations and furniture. It is somewhat brittle, and takes a high polish.
