Introduction |
Hopea cagayanensis (Foxw.) v. Slooten
- Protologue: Reinwardtia 3: 318 (1956).
Synonyms
- Balanocarpus cagayanensis Foxw. (1918).
Vernacular names
- Philippines: narek (Ibanag), narig (Negrito, Ibanag), narik (Ibanag, Iloko).
Distribution
The Philippines (north-eastern Luzon).
Uses
The timber is used as giam, especially for poles and piles and house construction.
Observations
- A medium-sized tree, bole generally branchless for 8-15 m and with a diameter of 25-50(-70) cm, without prominent buttresses; young parts and domatia densely persistently tawny pubescent.
- Leaves lanceolate, 8-10 cm × 2.5-4 cm, thin leathery, base unequal, acumen slender, up to 1.5 cm long, venation scalariform, midrib distinctly elevated above, secondary veins 9-12 pairs, arched at 55-65°, slender but prominent beneath.
- Stamens 15, shorter than the style, in 3 more or less unequal verticils, ovary small, ovoid, tapering into an equally long somewhat narrower stylopodium, style short, columnar.
- Fruit sepals short, subequal, 2 outer up to 9 mm × 7 mm, incrassate, 3 inner up to 10 mm × 10 mm, obtuse.
H. cagayanensis occurs locally abundantly in semi-evergreen forest at low altitude. The density of the wood is about 920 kg/m3 at 15% moisture content.
Selected sources
175, 258, 579, 599, 748.
Main genus page
Authors
- K.M. Kochummen (selection of species),
- F.T. Frietema (selection of species)
