Description

Alphonsea kinabaluensis is a plant species that belongs to the family Annonaceae that can reach up to 15 m height and 35 cm in diameter. When dried, the branches are brown and longitudinally wrinkled. The shape of leaves is narrowly elliptic or ovate-lanceolate with blade size ranging from 4.5−13.0 and 2.0−5.5 cm and have chartaceous texture. The colour of the leaves when dried is either grey-brown or brown on both surfaces. This species produces one or more flowers.  It produces two to five monocarps of globose to ellipsoidal shape with size up to 3 cm long and 2 cm diameter. Each monocarp may contains six seeds measuring 12−14 mm long, 8 mm diameter and 3−5 mm thick (Turner, 2014). It is native to Borneo specifically Sabah, Sarawak, Brunei and Kalimantan. The epithet name, kinabaluensis is derived from Mount Kinabalu, located in Sabah, Malaysia where this species was first found in year 1933. This species grows at altitudes up to 2,150 m in lowland, hill and montane forests including limestone forests (Turner, 2014).

Different characteristics have been identified for Alphonsea kinabaluensis grown in various varieties of forest. The species in the montane forest is characterised by the presence of the leaf blade upper surface, which has shiny honeycombed or pinpricked when seen under 20 times magnification, meanwhile the lowland forest has considerably smoother leaf upper surface with dark dots rather than pits. During flowering, we can see the difference clearly, the one grown at lowland produced three to five carpels per flower and monocarps covered with a dense brown to dark brown tomentum. On the other hand, the species grown at montane forest produced fewer carpels, which is about two to three carpels per flower and monocarps with short straw-coloured tomentum.
