Borneo is Borneo. Yet, Borneo is also part of Malaysia, Indonesia and
Tropical Asia.
To the best of my understanding Sarawak and Sabah (northwestern
Borneo) are part of Malaysia. Kalimantan, the largest part of the
island of Borneo, is part of Indonesia. Brunei Darussalam is part of
Tropical Asia. Yikes!
That made the job tough! I did find plants that were distributed in
Borneo, I also found plants from the other regions. What I did was
create a list of plants from all of the mentioned regions. Those
being Borneo, Malaysia, Indonesia and Tropical Asia since all of
those regions describe the island of Borneo. What I will do is list
the plant by name and then list the applicable area. I will also list
plants with worldwide, cosmopolitan and pantropical distributions.
The list:
