Nepenthes bongso (pronounced /nəˈpɛnθiːz ˈbɒŋˌsəʊ/, from Indonesian: after Putri Bungsu = youngest daughter; referring to local legend of the spirit guardian of Mount Marapi) is a highland Nepenthes pitcher plant species, native to Sumatra, where it grows at an altitude of 1000-2700 m. It is very similar to N. carunculata and there is much debate about whether the two should be treated as separate species.
| Character | N. bongso | N. dubia | N. talangensis | N. tenuis |
|---|---|---|---|---|
| Shape of upper pitchers | tubulate - infundibulate | tubulous in the lower part, infundibulate above the middle | tubulous to narrow infundibuliform in the lower half, ovate in the upper half | wide infundibulate, contracted below the mouth |
| Lid | orbiculate | narrow cuneate | broad-ovate | very narrow elliptical |
| Length/width ratio of upper pitchers | 3,3 | 1,9 | 2,3 | 1,75 |
No forms or varieties of N. bongso have been described (unless N. carunculata is considered conspecific).
[edit] Natural hybrids
The following natural hybrids involving N. bongso have been recorded.
- N. bongso × N. pectinata[1]
- N. bongso × N. singalana[1]
- N. bongso × N. talangensis[1]
In his 1928 monograph The Nepenthaceae of the Netherlands Indies, B. H. Danser mentioned what he thought was the hybrid N. bongso × N. pectinata; however, this plant material is now known to represent N. densiflora, a species described by Danser 12 years later.
