Abutilon theophrasti L.
(Familia Malvaceae )
Teofrastova lipica

Abutilon theophrasti L. , poreklom iz južne Azije, je nakon širenja u u Severnu Ameriku 1700 godine, postao invazivna korovska vrsta u svim poljoprivrednim područjima Amerike. Narodni naziv za ovu biljku je teofrastova lipica. Jednogodišnja je biljka, prosečne visine od 50-100 cm, obrasla dlakama beličaste boje. Listovi su sa dugačkim lisnim drškama, okruglasto srcastog oblika, a po obodu tupo nazubljeni. Sa obe strane listovi su sa priljubljenim prostim i zvezdastim dlakama. Žuti cvetovi su smešteni u pazuhu listova ili na vrhu stabljike u maloj štitolikoj cvasti. Plod je crna, dlakava čaura, koja je sastavljena od 13-16 plodića. Teofrastova lipica cveta u periodu od juna do septembra.
Smatra se da je veoma kompetitivna, odnosno oduzima hranljive materije i vodu od useva koje zakorovljuje. Najviše joj odgovaraju bogata zemljišta, ona koja su pogodna za poljoprivredne useve, te se najčešće kao korovska vrsta javlja u okopavinama, i to u usevu kukuruza, soje i šećerne repe, i povrtarskim usevima. Ukoliko se ne suzbija može da smanji prinos kukuruza i do 34%. Zbog alelopatskog delovanja, štete od ove korovske vrste u usevu soje su višestruke. Često uspeva i pored puteva, oko ljudskih naselja. U Kini i Kašmiru semena ove biljke koriste se u ljudskoj ishrani.
Na području Republike Srbije najviše je zastupljena u okolini Beograda, u Posavini, na području Fruške gore i u južnom Banatu.
