Barclaya wellyi is a species of perennial aquatic plant native to Sumatra, Indonesia. [1]
Barclaya wellyi is an aquatic plant with 2–5 cm long, 1 cm wide, stoloniferous, villous rhizomes. The 10-15 petiolate, cordate leaves are 6–10 cm long, and 6–10 cm wide. The petioles are 10–20 cm long. [2]
The nocturnal, 4 cm wide flowers are attached to 5–20 cm long peduncles. The outer tepals are 3 cm long. The four iner tepals are 1.5 cm long. Staminodes and fertile stamina are present. The flowers have 20-30 anthers. The stigmatic cup has 9 carpellary appendages. The ellipsoid fruit bears 2 mm long, spiny, ellipsoid, dark brown seeds. [2]
The diploid chromosome count is 2n= 36. [2]
It can reproduce vegetatively through the formation of stolons. [2]
It was first described by Suwidji Wongso, Isa Ipor, and Niels Jacobsen in 2022. [1]
The type specimen was collected by Suwidji Wongso in Sumatra, Indonesia on the 27th of May 2021. Material had been collected earlier from the type location, but it was only later recognised to be distinct. [2]
The specific epithet wellyi honours Mr. Welly Yansen. [2]
It is classified as data deficient (DD) under the IUCN criteria. [2]
It is only known from the type location, where it occurs beneath an old rubber plantation close to an oil palm plantation. The habitat is characterised by acid waters at water temperatures of 29 °C. It occurs sympatrically with Cryptocoryne minima Ridl. [2]

Barclaya is a genus of six species of flowering plants of the family Nymphaeaceae. Barclaya are aquatic plants native to tropical Asia. The genus was named in honour of the American-born English brewer and patron of science Robert Barclay.
Nepenthes jamban is a tropical pitcher plant endemic to northern Sumatra. The specific epithet jamban is the Indonesian word for "toilet" and refers to the shape of the pitchers.
Nepenthes flava is a tropical pitcher plant endemic to northern Sumatra, where it grows in montane forest at 1800–2200 m above sea level.
Nepenthes naga is a tropical pitcher plant endemic to the Barisan Mountains of Sumatra. It is characterised by a forked sub-apical appendage on the underside of the lid and an undulate lid margin. The specific epithet naga is the Indonesian word for "dragon" and refers to the distinctive lid appendage of this species as well as the large size of its pitchers. The name also references local folklore, which tells of dragons occurring in this species's habitat in the past.
Phalaenopsis kapuasensis, also known as the Kapuas Hulu Phalaenopsis, is a species of orchid endemic to Borneo. The specific epithet kapuasensis refers to the indonesian locality Kapuas Hulu, from which the type specimen was obtained.
