Q: Carnivorous plants of Southeast Asia and Pacifica

• Southeast Asia

A: This is a geographically complicated region of oceanic countries, starting with Peninsular Malaysia, Singapore, and Sumatra in the west, eastwards to Borneo and the Philippines, and then to New Guinea and all the other islands in the North and South Pacific (with the exception of New Zealand and the Chatham Islands). Yes, I include Pacific islands such as Hawai'i here.

The native carnivorous genera in this region are Aldrovanda, Byblis, Drosera, Nepenthes, and of course Utricularia.

Aldrovanda
This plant is supposedly recorded on the island of East Timor. Otherwise, it is absent from this region.

Byblis
The species B. liniflora--mostly restricted to Australia, also occurs in New Guinea. Some speculate that the New Guinean plants might actually be B. filifolia.

• Drosera
  spatulata
• Drosera
  rotundifolia
• Drosera
  petiolaris
• Drosera
  peltata
• Drosera
  burmannii
• Drosera
  anglica

Drosera
A few species of Drosera occur in the region; from this list D. neocaledonica and D. spatulata var. bakoensis are the only sundews endemic to the area. The reported occurrence of D. rotundifolia in New Guinea is a matter of considerable speculation:

• D. anglica: USA (Hawai'i); also in Europe, mainland Asia, and North America.
• D. banksii: Indonesia (New Guinea) and Papua New Guinea; also in Australia.
• D. burmannii: Malaysia, Indonesia (Borneo, Celebes, New Guinea, Java), Papua New Guinea, and Palau; also in Australia and mainland Asia.
• D. indica: Malaysia, the Philippines, Indonesia (Borneo, Celebes, New Guinea), and Papua New Guinea; also in Africa, mainland Asia, and Australia.
• D. neocaledonica (endemic): New Caledonia.
• D. peltata: Indonesia (New Guinea, and elsewhere?), Papua New Guinea, the Philippines; also mainland Asia, Australia, and New Zealand.
• D. petiolaris: Indonesia (New Guinea) and Papua New Guinea; also in Australia.
• D. rotundifolia: supposedly in Indonesia (New Guinea); also in North America, Europe, and mainland Asia.
• D. spatulata: the Philippines, Indonesia (Borneo, New Guinea), Malaysia (Borneo), and Palau; also mainland Asia, Australia, and New Zealand.
• D. spatulata var. bakoensis (endemic): Borneo.

• Nepenthes
  ventricosa

Nepenthes
This genus is without a doubt, the carnivorous plant king, queen, and most other levels of royalty for the region! Nearly all the species in the genus are restricted to Southeast Asia, and to avoid duplication of FAQ content I will merely point you to the following references:
Nepenthes of Borneo
Nepenthes of Sumatra
Nepenthes of Peninsular Malaysia
Nepenthes of the Philippines
Nepenthes of Sulawesi, Waigeo, and New Guinea
Nepenthes of a few other areas

• Utricularia
  uliginosa
• Utricularia
  minor
• Utricularia
  gibba
• Utricularia
  dichotoma
• Utricularia
  aurea

Utricularia
As usual, this genus makes a nice showing with several species that are endemic to the region treated on this page:

• U. aurea: the Philippines, Malaysia, Indonesia (Sumatra, Java, Borneo, Celebes, Lesser Sunda Is., New Guinea), and Papua New Guinea; also in Australia and mainland Asia.
• U. australis: Indonesia (Sumatra, Java, New Guinea) and the Philippines; also in Europe, mainland Asia, Africa, the middle East, Australia and New Zealand.
• U. bifida Malaysia, Indonesia (Sumatra, Java, Borneo, Celebes, New Guinea), the Philippines, Palau, Micronesia, and Guam; also in mainland Asia and Australia.
• U. caerulea Malaysia, Indonesia (Sumatra, Borneo, Java, New Guinea), the Philippines, Papua New Guinea, Palau, Guam; also in Africa, mainland Asia, and Australia.
• U. chrysantha Indonesia (New Guinea) and Papua New Guinea; also in Australia.
• U. dichotoma New Caledonia; also in Australia and New Zealand.
• U. foveolata: the Philippines, Indonesia (Java); also in Africa, mainland Asia, and Australia.
• U. gibba: Malaysia, Indonesia (Sumatra, Java, Borneo, Celebes, New Guinea), the Philippines, Palau, and New Caledonia; also in the Americas, Europe, Africa, mainland Asia, Australia, and New Zealand.
• U. heterosepala (endemic): the Philippines.
• U. hirta: Malaysia (Borneo); also in mainland Asia.
• U. involvens: Malaysia; also in mainland Asia and Australia.
• U. limosa: Malaysia, Indonesia (New Guinea); also in mainland Asia and Australia.
• U. minor: Papua New Guinea; also in North America, Europe, the middle East, and mainland Asia.
• U. minutissima: Malaysia, Indonesia (Sumatra, New Guinea), Papua New Guinea, and the Philippines; also in mainland Asia and Australia.
• U. muelleri: Papua New Guinea; also in Australia.
• U. pulchra (endemic): Indonesia (New Guinea).
• U. punctata: Malaysia, Indonesia (Sumatra, Borneo); also in mainland Asia.
• U. scandens: Malaysia, Indonesia (New Guinea, Aru Is.); also Africa and mainland India.
• U. steenisii (endemic): Indonesia (Sumatra).
• U. striatula: the Philippines, Malaysia, Indonesia (Borneo, Sumatra, Java, Celebes, Lesser Sunda Is., Maluku, New Guinea), and Papua New Guinea; also Africa and mainland India.
• U. subulata: Malaysia, Indonesia (Borneo); also in the Americas, Europe, Africa, mainland Asia, and Australia.
• U. uliginosa: Malaysia, Indonesia (Sumatra, Java, Borneo, New Guinea), Papua New Guinea, Palau, Guam, New Caledonia; also in mainland Asia and Australia.
• U. vitellina (endemic): Malaysia.
