Distribution and habitat : Cynometra iripa 
is distributed throughout tropical southern 
and south-eastern Asia (including India, 
Bangladesh, Myanmar, Cambodia, Vietnam 
and Thailand), Malesia (Malaysia, Indonesia, 
Singapore, the Philippines and New Guinea), 
Micronesia, Melanesia (Solomon Islands, 
New Caledonia) and Australia, at altitudes 
reportedly to 500 m (Ding Hou 1996). Within 
Australia, C. iripa has been recorded in 
Queensland on the mainland and off shore 
islands from Cape York to the Mackay area, 
as well as west to East Arnhem Land in the 
Northern Territory (Map 1); altitude near sea- 
level to 20 m. 
In Australia, Cynometra iripa is a plant 
of back mangal areas, rarely of upstream 
wetlands (Keatings Lagoon near Cooktown 
lBooth 5243 & Lynch]) or adjoining 
monsoon forest (Arnhem Land [Westaway 
3190]). In Queensland it commonly co¬ 
occurs with Acacia polystachya A.Cunn.
