Ziyini izici zemithi yesundu?

Izihlahla zesundu yizitshalo ezinhle ongaba nazo nengadi ebukeka eshisayo ngisho nasezindaweni ezinesithwathwa. Amaqabunga, isiqu (isiqu) nendlela akhula ngayo yinhle kakhulu ukuthi asikho esinye isitshalo esifana naso esingatholakala.

Ukuhlobisa ngazo kuhlale kuyintokozo, njengoba kunezinhlobo ezingaphezu kwezingu-3000 futhi ziningi, ngokuqinisekile, ezingaguqulwa ukuze zihlale kahle endaweni yangakini. Kodwa, Uyazi ukuthi ziyini izici zemithi yesundu? 

Imithi yesundu ingeyomndeni wakwa-Arecaceae (phambilini owawuyiPalmaceae). Ziyizitshalo monocotNgamanye amagama, hhayi nje kuphela ukuthi abanakho ukukhula kwesibili (njengezihlahla), kepha futhi nalapho imbewu ihluma, kuhluma kuphela i-cotyledon eyodwa. Singasho ukuthi "bangodade asebekhulile" bamakhambi, ngoba, empeleni, amasundu angotshani obukhulu.

Izici zayo eziyinhloko, okungukuthi, lezo okufanele sizibheke lapho sifuna ukuzikhomba, yilezi:

• Ifa: uhlelo lwabo lwempande luyathandeka, okusho ukuthi abanampande enkulu. Azikho phezulu futhi azijuli ngaphezu kwama-60cm. Futhi, azihlaseli.
• UStipe: yisiqu noma isiqu samanga. Kungaba i-multicaule (iziqu ezimbalwa), noma i-unicaule. Ngokuya ngezinhlobo kungaba yinde, ibe mfushane, ibe yinhle, ibe yinhlese, imbozwe ngemicu noma ameva, igibele (Calamus) noma ngaphansiAma-nyut fruticans). Abanye bangamelana namandla eziphepho, njengoba izihlahla zesundu zintula i-cambium ngakho-ke banesiqu esivumelana nezimo. Kepha abakwazi ukuvuselela izicubu zangaphandle: azikwazi ukupholisa amanxeba.
• Kushiya: kungaba pinnate (Butia, Phoenix, I-Chamaedorea, njll.), okuyilezo lapho izingxenye ezigxile kamuva zivela ku-rachis; i-bipinnate (i-Caryota), okuyilabo amapheshana abo aphinwe kabili; eshaya izandlaAma-Chamerops, ICopernicia, iTrithrinax, njll.) Okuyizo ezinesimo sabalandeli; nama-costapalmadas (uSabal, Livistona, Raphis, Licuala), okungamacembe amise okwe-fan okufakwa i-petiole yakhe esesimeni sobambo embizeni.
• I-inflorescence: iqoqo lezimbali. Zivikelwe ngama-bracts abizwa ngokuthi ama-spathes.
• Izikhukhula: mancane kakhulu, akhiwa ngamacembe ayi-6 kuma-whorls ama-2. Izinhlobo eziningi zine-monoecious (enezinhlobo zezinsikazi nabesilisa), kepha kukhona futhi lezo ezi-dioecious. Ngokulandelayo, izihlahla zesundu zingaba yi-monocarpic (Corypha), okungukuthi, ngemuva kokuqhakaza lapho zifa zishiya inqwaba yezimbewu, noma i-polycarpic, eqhakaza kanye ngonyaka kusukela lapho ifinyelela ebudaleni.
• Izithelo: zingaba ngesimo se-drupe (Cocos) noma i-drupe (i-Phoenix), futhi zibe nesisindo esiguquguqukayo, kusuka kumagremu ambalwa kuye ku-25kg.
