Description and phenology
The kalantas tree can grow up to 25 metres (82 ft) and can measure up to 25 centimetres (9.8 in) in diameter.[4] The color of the bark ranges from yellowish to dark brown and the inner bark is light brown[2] while trunk is straight and terete.[4] The leaves can be described as compound, alternate oblong or broadly lanceolate[clarification needed].[4] The fruit of the kalantas tree is a capsule that can be ellipsoid or oblongoid that measures 3–4 centimetres (1.2–1.6 in) long.[2]
Flowering occurs from June to August while fruiting occurs from September to November.[5] In Mount Makiling, Laguna, Philippines, seed gathering takes place from February to March.[5]
Distribution, importance and conservation status
Generally scattered all over the Philippines particularly in the Balabac group of islands, the kalantas tree can be found in the hills of a forest situated in low to medium altitudes.[4] The wood of the tree is used for making boxes, furniture or plywood.[4][5] Kalantas has been categorized by the International Union for Conservation of Nature (IUCN) as Data Deficient[2] but it was reported that kalantas is exhausted due to logging and kaingin (a Tagalog term for slash-and-burn).[4] Reforestation efforts have been done in the Philippines and the kalantas tree is included in these efforts.[6] One of the efforts were done by the Philippine Department of Environment and Natural Resources during the term of then President Gloria Macapagal-Arroyo where the president herself planted a seedling of a kalantas tree,[7] which is the favored tree promoted by the president.[8]
