Carnivorous plants nepenthes careyorum

Carnivorous plants nepenthes careyorum is a species of pitcher plant endemic to the island of Seram, Indonesia. Carnivorous plants are those that feed upon animals, using enzymes and digestive fluids.

Etymology

The specific epithet nepenthes careyorum comes from the Greek word meaning carnivorous. The species epithet is a reference to the island of Seram where the species was first collected.

Taxonomy

Nepenthes careyorum was first described in 2017, and the description was published in the journal Phytotaxa. The authors named the species in honour of Gwen Carey, a botanist who has worked with Nepenthes on Seram. The authors chose the name to reflect the resemblance of N. ,careyorum to the Malay (Indonesian) word careyor, which translates to "hornbill".

The holotype of N. ,careyorum is a mature plant from the species’ only known locality, Tamanjaya Umor. It was collected by Gwen Carey on 22 March 2009, and has been conserved at the National Herbarium of the Netherlands (B) since.

Description

Nepenthes careyorum is a climbing vine that grows to a height of approximately 1.2 metres. Its stem is densely glandular, with bracts that are also densely glandular. The lamina is lanceolate in shape, and has a serrated margin. The upper surface of the lamina is purplish in colour and densely glandular, and is covered in minute blackish-brown dots.

The pitchers of N. ,careyorum are more or less elliptic in shape. They are around 3.6 ,cm long, 1.5 ,cm wide, and cylindrical in structure, with a prominent rim. The pitchers of N. ,careyorum are also deep in colour, ranging from a dark-brownish-red to a purple-red. As with many other members of its genus, the peristome of N. ,careyorum is distinctly flared, it is warty in appearance, and with small teeth on the edge.

The lower surface of the pitchers have three prominent glands situated at the base, and two glands at the upper part of the pitchers' rim. Pitcher hairs also grow out of the glands, and help to create a glaucous appearance. The hairs of N. ,careyorum are thought to contain an alkaloid, with similar compounds being found in the venoms of certain cobras and some sea snakes.

The odour of N. ,careyorum is noted as having "a pleasant peppery, slightly sour taste", with little to no trace of ammonia. The plant's aril is similar in colour to the pitcher. The aril is used by females to attract males, and by non-reproductive, male plants to attract female plants. It is also reputed to have a strong "musky" smell.

Like all other Nepent
