'''''vAeschynomene virginica''''' - [[Burchoqdoshlar|dukkaklilar oilasiga mansub]] noyob gulli o'simlik turi '''Virjiniya qo'shma vechkasi''' va '''sezgir qo'shma''' nomlari bilan ham mashhur.  [[Amerika Qoʻshma Shtatlari|Amerika Qo'shma Shtatlarining]] Sharqiy qirg'og'i mazkur o'simlikning vatani bo'lib, u yerda har yili o'zgaruvchan global turlar soni 20 ga yaqin<ref name="tnc">{{Veb manbasi |sarlavha=The Nature Conservancy |url=http://www.natureserve.org/explorer/servlet/NatureServe?searchName=Aeschynomene+virginica |kirish sanasi=2022-09-02 |arxivsana=2008-06-02 |arxivurl=https://web.archive.org/web/20080602205427/http://www.natureserve.org/explorer/servlet/NatureServe?searchName=Aeschynomene+virginica }}</ref>. Hisob-kitoblarga ko'ra, [[New Jersey|Nyu-Jerseyda]] ikkita populyatsiyasi, shu jumladan bir necha ming vakili, [[Maryland|Merilenddagi]] bir necha yuz o'simlikning bir populyatsiyasi, [[Shimoliy Karolina|Shimoliy Karolinadagi]] xandaqlarda bir nechta o'zgaruvchan va beqaror populyatsiyalari va [[Virginia|Virjiniya shtatida]] 5000 ga yaqin vakilni o'z ichiga olgan bir nechta populyatsiyasi aniqlangan. Yashash joyining o'zgarishi o'simlik o'sishi mumkin bo'lgan joylar sonini qisqartirdi<ref name="tnc" />. O'simlik 1992-yilda Amerika Qo'shma Shtatlarining federal ro'yxatiga kiritilgan xavf ostidagi turlar dan biriga aylandi<ref name="tnc" />.

''Aeschynomene virginica'' bir yillik oʻt boʻlib, tik oʻsadi va balandligi ikki metrga yetadi. Navbatma-navbat joylashgan barglarning har biri ko'p juft tukli yaproqlardan iborat. Barglari tashqi ta'sirga o'ta sezgir, teginganda buklanadi. Gullash yozda va kuzning boshida sodir bo'ladi. No'xat guliga o'xshash gulning uzunligi taxminan bir santimetr va sariq rangga ega, to'liq qizil tomirlar bilan qoplangan. Gullar kichik Skipper (''Ancylozypha numitor''  va barg kesuvchi asalarilar (Megachilidae oilasi) kabi hasharotlar tomonidan [[Changlanish|changlantiriladi]]. Meva uzunligi 7 santimetrgacha bo'lgan [[Dukkakli don ekinlari|dukkak]] po'stlog'iga ega, urug'lari toraygan bo'laklar orasida joylashgan. Bu bo'laklar suvda ham suzadi va urug'lar darhol tushib qolmasa, suvga sochilib ketishi mumkin. 

Bu o'simlik suv oqimi harakati kuzatiladigan, ammo sho'rlanish darajasi past bo'lgan chuchuk suv botqoqliklarida uchraydi. U asosan boshqa o'simliklardan tozalangan hududlar, buzilgan joylarda o'sadi, masalan, yangi cho'kilgan qirg'oqlar yoki yaqinda [[Ondatra|ondatralar]] tomonidan qazilgan yerlar bu o'simlik yashashi uchun qulay muhit hisoblanadi. Uning urug'lari nam tuproqlardan ham unib chiqadi, lekin suv ostida, qalin o'simliklari bo'lgan joylarda yaxshi o'sa olmaydi<ref>Griffith, A. B. and I. N. Forseth. (2003). Establishment and reproduction of ''Aeschynomene virginica'' (L.) (Fabaceae) a rare, annual, wetland species in relation to vegetation removal and water level. ''Plant Ecology'' 167:1 117.</ref>. To'lqinli yashash muhitini ushlab turish qobiliyatiga qaramay, u cho'kindi jinslarning kuchayishi va inson faoliyati, sanoatning rivojlanishi, [[ifloslanish]] yoki qayiqlardagi [[eroziya]] kabi jiddiy o'zgarishlarga chidamli emas.
