Nepenthes bongso /nɪˈpɛnθiːz ˈbɒŋsoʊ/ is a tropical pitcher plant endemic to Sumatra, where it has an altitudinal distribution of 1000–2700 m above sea level. [10] [11] The specific epithet bongso refers to the Indonesian legend of Putri Bungsu (literally "youngest daughter"), the spirit guardian of Mount Marapi. [10]
The species was formally described by Pieter Willem Korthals in his 1839 monograph, " Over het geslacht Nepenthes". [2]
Nepenthes carunculata [note a] is considered a heterotypic synonym of N. bongso by most authorities. [8] [9] [10] [12] The infraspecific taxon Nepenthes carunculata var. robusta was described in 1994 by Joachim Nerz and Andreas Wistuba. [13] It is an extreme variety of this taxon with a large, flared peristome. [13]
In his Carnivorous Plant Database, taxonomist Jan Schlauer treats N. junghuhnii (sensu Macfarlane) as a possible synonym of N. bongso. [14]
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 |
The following natural hybrids involving N. bongso have been recorded.
In his 1928 monograph " The Nepenthaceae of the Netherlands Indies", B. H. Danser mentioned what he thought was the hybrid N. bongso × N. pectinata; [5] however, this plant material is now known to represent N. densiflora, [10] a species described by Danser 12 years later. [15]
