Its leaf petioles are covered with the same white trichomes, and are {{convert|3-5|cm|abbr=on}} long. Its leaflets are oval-shaped and pointy, or acuminate, towards their apex. The leaflets range from {{convert|4-6|cm|abbr=on}} in length. The herb's inflorescence is axillary, meaning it rises from the same node as a leaf rather than from the end of a stem. The peduncle of the plant is covered with the same white trichomes as the stem. Its flower petals are a pale yellow.[4]Habitat and ecologyThe plant is common to Thailand, Cambodia, India and Sri Lanka, and grows between {{convert|5-2500|m|abbr=on}} in altitude.[5] It is a common component of the ground flora in monsoon forests, and particularly Sal forests. It grows in shady wet highland slopes where the plant can root from stem nodes.[4] UsesLivestock often graze on the plant, and it is a good soil binder and can be used for soil conservation.[4] ConservationThe monsoon forest habitat of the plant is threatened by the general expansion of human populations, especially by expansion of farmland. The species is listed as present in Sanjay Gandhi National Park in India and various national parks in Thailand. It is also present in the national gene bank in New Delhi.[6] References1. ^1 {{cite book |title= CRC World Dictionary of Medicinal and Poisonous Plants: Common Names, Scientific Names, Eponyms, Synonyms, and Etymology |author= Umberto Quattrocchi |edition= reprint |publisher= CRC Press |year= 2016 |isbn= 9781482250640 |page= 3904}} {{Taxonbar|from=Q15527825}}2. ^{{cite book |page= 198 |title= Broadening the Genetic Base of Grain Legumes |editor= Mohar Singh |editor2=Ishwari Singh Bisht |editor3=Manoranjan Dutta |edition= illustrated |publisher= Springer |year= 2014 |isbn= 9788132220237}} 3. ^{{cite book |page= 54 |title= Wild Relatives of Cultivated Plants in India: A Reservoir of Alternative Genetic Resources and More |author= Anurudh Kumar Singh |publisher= Springer |year= 2017 |isbn= 9789811051166}} 4. ^1 2 {{cite book |title= The Asian Vigna: Genus Vigna subgenus Ceratotropis genetic resources |author= Norihiko Tomooka |author2=D.
