(1) Uninzi lwezityalo zesanti ezingapheliyo zineengcambu ezomeleleyo ezandisa ukufunxwa kwamanzi kwisanti.Ngokuqhelekileyo, iingcambu ziphindwe kaninzi ngokunzulu kwaye zibanzi njengobude besityalo kunye nobubanzi.Iingcambu ezinqamlezileyo (iingcambu ezisecaleni) zinganabela kude kuzo zonke iindawo, aziyi kubekwa, kodwa ziya kusasazwa kwaye zikhule ngokulinganayo, aziyi kugxila kwindawo enye, kwaye aziyi kutsala isanti emanzi kakhulu.Umzekelo, izityalo zomngcunube ezityheli zidla ngokuba malunga neemitha ezi-2 ubude, kwaye i-taproots yazo inokungena kumhlaba oyisanti ukuya kubunzulu obuziimitha ezi-3.5, ngelixa iingcambu ezithe tyaba zinokwandisa i-20 ukuya kwi-30 yeemitha.Nangona umaleko weengcambu ezithe tyaba zibonakaliswe ngenxa yokhukuliseko lomoya, akufanele ube nzulu kakhulu, kungenjalo isityalo sonke siya kufa.Umzobo we-13 ubonisa ukuba iingcambu ezisecaleni zomngcunube otyheli ezityalwe unyaka omnye kuphela zinokufikelela kwiimitha ezili-11.
(2) Ukuze kuncitshiswe ukuselwa kwamanzi nokunciphisa indawo yokuphefumla, amagqabi ezityalo ezininzi ashwabana kanobom, amile okwentonga okanye abe yisipike, okanye angabi namagqabi, aze asebenzise amasebe ukwenza iphotosynthesis.IHaloxylon ayinamagqabi kwaye igaywe ngamasebe aluhlaza, ngoko ibizwa ngokuba "ngumthi ongenamagqabi".Ezinye izityalo azinamagqabi amancinane nje kuphela kodwa zineentyatyambo ezincinane njengeTamarix (Tamarix).Kwezinye izityalo, ukuze kuthintelwe ukuphefumula, amandla odonga lweseli ye-epidermal yeqabunga iba lignified, i-cuticle iyaqina okanye indawo yeqabunga igutyungelwe ngumaleko we-waxy kunye nenani elikhulu leenwele, kunye ne-stomata yezicubu zeqabunga. zibanjisiwe kwaye bavalwe ngokuyinxenye.

(4) Izityalo ezininzi, isakhono esinamandla sokuntshula, isakhono esomeleleyo se-lateral branching, isakhono esinamandla sokuxhathisa umoya nesanti, kunye nobuchule obunamandla bokuzalisa isanti.ITamarix (iTamarix) ifana nale: Xa ingcwatyelwe esantini, iingcambu ezingaqhelekanga zisenokukhula, yaye amathupha anokukhula ngamandla ngakumbi.ITamarix ekhula kwimigxobhozo esemazantsi isoloko ihlaselwa yintlabathi ekhawulezayo, nto leyo ebangela ukuba amatyholo afumbe intlabathi ngokuqhubekayo.Nangona kunjalo, ngenxa yendima yeengcambu ze-adventitious, i-Tamarix inokuqhubeka ikhula emva kokulala, ngoko "ukunyuka kwamanzi kuphakamisa zonke izikhephe" kwaye zenze izihlahla ezinde (iingxowa zesanti).
(5) Izityalo ezininzi zinetyuwa eninzi, ezinokufunxa amanzi kumhlaba onetyuwa eninzi ukuze zilondoloze ubomi, njengeSuaeda salsa nesalsa claw.
