Distribution of
D. celebica var. longilobata
(●).
Distribution.
Sulawesi (Central Sulawesi).
Ecology and habitat.
Montane forest dominated by
Agathis
at ca. 2000 m elevation.
Note.
This variety is known only from the type and differs from the var.
celebicca
by its long triangular calyx lobes (2-3 mm long), persistent in fruit. The length of the calyx lobes is often similar to that of
D. schumannii
from New Guinea, though they are usually caducous in that species.
