When I first got to know, years back, that the tropics had native brambles (raspberries and such), I was rather surprised. After all, brambles and raspberries are plants much more strongly associated with temperate regions. But here it is. The very same kind of scrambling habit. The prickles. The white bramble flowers.
The species is very widespread and I have seen it in the Southeast Asian tropics. The variety name hints at it’s appearance. The ‘trilobus’ presumably refers to it’s three-lobed leaves. The other variety, var. moluccanus is not as lobed. The introduced R. alceifolius has more strongly lobed leaves.
I’ll be waiting to try the raspberries when they appear.
