U. Maschwitz et al., CLERODENDRUM-FISTULOSUM (VERBENACEAE), AN UNSPECIFIC MYRMECOPHYTE FROM BORNEO WITH SPONTANEOUSLY OPENING DOMATIA, Blumea, 39(1-2), 1994, pp. 143-150
Clerodendrum fistulosum Becc. is a true myrmecophyte as it offers nest
ing space for ants in hollow internodes. In contrast to previous repor
ts our investigations proved that these domatia open by themselves, th
us providing cavities for a variety of different ant species. In Saraw
ak, Malaysia, we did not find an obligate relationship between C. fist
ulosum and a specific ant-partner. For comparison, studies on herbariu
m material of other Clerodendrum species were carried out: a further s
pecies, C. deflexum from the Malay Peninsula and Sumatra presumably al
so is myrmecophytic.
