Description
editVegetative characteristics
editBarclaya kunstleri is an aquatic plant with slim, stoloniferous, villous, 2–4 cm long, and 0.5 cm wide rhizomes. The stolons can exceed 50 cm in length. The petiolate, ovate to circular, bright green leaves are 5–10 cm long and 6–10 cm wide. The green, pubescent to glabrous petioles are 5–10 cm long.[2]
Generative characteristics
editThe nocturnal, 5–6 cm wide flowers are attached to 10–20 cm long peduncles. The outer tepals are 2.5–3.0 cm long, and the 3-4 inner tepals are 1 cm long. The flowers have 20-30 anthers. The stigmatic cup has 8-10 carpellary appendages. The globose to elongate, 1 cm long fruit bears echinate, ellipsoid, 1 mm long, and 0.5 mm wide seeds.[2]
Cytology
editThe diploid chromosome count is 2n = 36.[2] The chloroplast genome is 160051 bp long.[3]
Reproduction
editVegetative reproduction
editIt can reproduce vegetatively through the formation of stolons.[2]
Taxonomy
editPublication
editIt was first described as Barclaya motleyi var. kunstleri King by George King in 1889. Later, it was elevated to the status of a separate species Barclaya kunstleri (King) Ridl. by Henry Nicholas Ridley in 1922.[1][4][5]
Type specimen
editThe type specimen was collected by Hermann H. Kunstler (1837-1887) in West Malaysia in July 1885.[6][2]
Classification status
editThe status of this species is disputed. It is rejected by some,[1] but accepted by others.[2][7][8][9]
Etymology
editThe specific epithet kunstleri honours Hermann H. Kunstler.[10][11][12]
Conservation
editIt is classified as data deficient (DD) under the IUCN criteria.[2]
Ecology
editHabitat
editIt occurs in small mountain streams with sandy, or muddy substrates.[2]
