Непентес spatulata: тропический кувшинный цветок Индонезии.

Species of pitcher plant from Indonesia

Nepenthes spathulata /n//ᵻ/'/p//ɛ//n//θ//iː//z// /,/s//p//æ//θj//ʊ/'/l//ɑː//t//ə/ is a tropical pitcher plant native to Java and Sumatra, where it grows at elevations of between 1100 and 2900 m above sea level. The specific epithet spathulata is derived from the Latin word spathulatus, meaning "spatula shaped", and refers to the shape of the lamina. The next major taxonomic treatment of N. spathulata came only in 1986, when Rusjdi Tamin and Mitsuru Hotta treated the species in synonymy with N. singalana. The authors also lumped four other species under N. singalana: N. carunculata, N. gymnamphora, N. pectinata, and, by implication, N. densiflora. On Mount Dempo, Mike Hopkins, Ricky Maulder and Bruce Salmon found what they believed to be a new species of Nepenthes. They published an account of their discovery in a 1990 issue of the Carnivorous Plant Newsletter. It reads:

In 1997, the genus Nepenthes was revised in its entirety by Matthew Jebb and Martin Cheek in "A skeletal revision of Nepenthes (Nepenthaceae)". The authors kept N. spathulata as a valid species and designated Lieftinck 11 as its lectotype. In 2004, a Javan taxon resembling N. spathulata was discovered by Adrian Yusuf. Two years later, it was given the informal name N. adrianii /n//ᵻ/'/p//ɛ//n//θ//iː//z// /,/æ//d//r//i/'/æ//n//i//aɪ/ by Batoro, Wartono, and Matthew Jebb, and was treated as a distinct species in the book Trubus Info Kit: Nepenthes. These plants typically have reddish green pitchers with red speckles and a red peristome. Nepenthes adrianii is generally considered to be a heterotypic synonym of N. spathulata.

Nepenthes spathulata is a climbing plant. The stem may grow to a height of 5 m but is only up to 8 mm in diameter. Internodes are up to 15 cm long and cylindrical to angular or rhomboid in cross section. The pitcher lid or operculum is ovate, lacks appendages, and is often slightly cordate. The spur, located near the base of the lid, is usually branched and may be up to 10 mm long. Plants growing in mossy forest and lower montane forest usually have an epiphytic habit, while those from stunted upper montane forest on summit ridges generally occur terrestrially. Nepenthes spathulata is also known to grow terrestrially in high altitude peat swamp forest near Lake Kerinci, at an altitude of 1100 m. At this location, N. spathulata grows alongside N. ampullaria, N. gracilis, N. mirabilis, N. reinwardtiana, and N. tobaica. At least three natural hybrids of N. spathulata have been recorded there. The Nepenthes species and hybrids at this site exhibit high levels of introgression. The vegetation is dominated by species of the genera Rhododendron and Melastoma, as well as orchids and ferns. It is very stunted and dense, with few trees exceeding 3 m in height. It is somewhat reminiscent of the highland heath forests around Bareo in Sarawak, Borneo.]] The closest relative of N. spathulata appears to be N. singalana. It differs from this species in having a peristome that is contracted towards the front and very wide at the sides. In addition, it has less prominent peristome ribs and shorter teeth than N. singalana. However, Jebb and Cheek considered it more likely that N. bongso, rather than N. spathulata, is a close relative of N. densiflora.

Natural hybrids involving N. spathulata are relatively rare, as few other species grow sympatrically with it. Seven putative hybrids have been recorded to date, at least three of which are known from a unique highland peat swamp habitat around Lake Kerinci.

Nepenthes mirabilis × N. spathulata is one of the hybrids recorded from the Lake Kerinci peat swamp. The parent species are not known to be sympatric at any other location and so this hybrid is unlikely to occur elsewhere. The pitchers of N. mirabilis × N. spathulata are reddish brown with dark speckles and a bright yellowish red peristome. It differs from N. mirabilis in its wider peristome, which bears distinct teeth and more pronounced ribs. From N. spathulata, it differs in having chartaceous, sub spathulate leaves, usually with fimbriate margins. and must have collected N. spathulata during this time.
