Barclaya longifolia is a species of perennial aquatic plant native to the region of Indo-China to Northwest Peninsular Malaysia. [2]
Barclaya longifolia is a submerged, perennial, aquatic herb [3] with ovoid, tuberous, stoloniferous, 2-3 cm long, and 0.5-1.5 cm wide rhizomes. [4] The linear-lanceolate, 12-30 cm long and 2-5 cm wide leaves with an obtuse apex, and a cordate base have an undulate margin. [5] The abaxial leaf surface displays red colouration. [3] The petioles are 6-25 cm long. [6]
The submerged and cleistogamous, or emerged and chasmogamous, [7] 4-6 cm wide flowers are attached to 5-30 cm long peduncles with numerous trichomes. [4] The sepals are 1.5-2.5 cm long, and 0.5-0.6 cm wide. [6] The syncarpous, inferior gynoecium consists of 8-14 carpels. [8] The globose, reddish green to whitish, 1-2 cm wide fruit bears 1mm long, and 0.5 mm wide, echinate, brownish red, globose seeds [4] without an arillus. [6] [8] [9]
The diploid chromosome count is 2n = 36. [4] The chloroplast genome is 158359 bp long. [10]
The rhizomes are stoloniferous. [4]
Barclaya longifolia can produce autogamous, submerged, cleistogamous flowers, [6] [7] [4] [5] as well as emergent chasmogamous flowers. [7]
It was first described by Nathaniel Wallich in 1827. [2] It is the type species of its genus. [6] [4]
The type specimen was collected by Wallich in Rangoon, Myanmar in August 1826. [4] [6]
The specific epithet longifolia, from the Latin longus meaning "long", and folius meaning "leaf", means long-leaved. [11] [12]
The IUCN conservation status is least concern (LC). [1] It may be endangered in Peninsular Malaysia. [4] In India, it is a rare species. [13]
It occurs in quickly flowing rivers, streams, and stagnant pools. Disturbance of the substrate by wild boar may be beneficial for the establishment of Barclaya longifolia seedlings in their natural habitat. [4]
It is a popular aquarium plant. [6] [5] [1] It can be easily cultivated in a mixture of pH-neutral, loamy and mineral soils [4] at temperatures of 26-29°C. [14]
