Akusiyiyo yonke imithi enala malungu omzimba akhankanywe apha ngasentla. Umzekelo, imithi emininzi ye-palm ayinamasebe, isaguaro cactus zaseMantla eMelika azinamagqabi asebenzayo, umthi wee-''fern'' ayivelisi maxolo arhabaxa, njalo njalo. Xa sijonga ukumila nobukhulu bayo, zonke ezi zityalo zithahwa nje ngemithi xa zizonke. Imithi yahluka-hlukene kakhulu. Isityalo esikumila kunje sifana nqwa nomthi, kodwa sibe sona isisityalo esincinane, esineziqu ezininzi kunye/okanye namasebe akhulela kufuphi nomhlaba, kuthiwa lityholo (okanye inkanga). Nangona oku kuyinyaniso, akukho mahluko ucacileyo phakathi kwamatyholo ne,ithi. Sijonge ubuncinane baso esi sityalo, ibonsai izityalo bezingenakuba 'yimithi', kodwa ke masingabhidanisi indlela ezimile ngayo izinto kunye nobukhulu bazo. Imbewu ye-spruce alingeni ncam kwindlela ochazwa ngayo umthi, kodwa zonke ii-spruces ziyimithi.
