Ziintoni iimpawu zesundu?

Imithi yesundu zizityalo ezimangalisayo onokuthi ube nazo kwigadi ekhangeleka itropiki nkqu nakwiimozulu ezinqabileyo. Amagqabi, isiqu sayo (isiqu) nendlela akhula ngayo intle kakhulu, kangangokuba asikho esinye isityalo esifana nesi esinokufunyanwa.

Ukuhlobisa kunye nabo kuhlala kumnandi, njengoko kukho iintlobo ezingaphezu kwe-3000 kwaye kukho ezininzi, ngokuqinisekileyo, zinokutshintshwa ukuze ziphile kakuhle kwindawo yakho. Kodwa, Ngaba uyazi ukuba ziziphi iimpawu zesundu? 

Imithi yesundu yeyosapho lweAarcaceae (eyayisakuba yiPalmaceae). Zizityalo monocotNgamanye amagama, ayaneli nje ukuba ayinako ukukhula okwesibini (njengemithi), kodwa naxa imbewu ihluma, kuphela ihlumela elinye icotyledon. Singatsho ukuba "ngoodade abadala" bemifuno, kuba, amasundu yingca enkulu.

Ezona mpawu zayo ziphambili, oko kukuthi, ezo kufuneka sijonge kuzo xa sifuna ukuzichonga, zezi:

• Ilifa: Inkqubo yabo yeengcambu iyathandeka, oko kuthetha ukuba abanangcambu iphambili. Azikho ngaphezulu kwaye azingeni nzulu kune-60cm. Kananjalo, ayisiyongxaki.
• Stipe: sisimboko okanye isiqu sobuxoki. Inokuba yi-multicaule (iziqu ezininzi), okanye i-unicaule. Ngokuxhomekeke kwiintlobo, ingaba yinde, imfutshane, ilungile, irhabaxa, igqunywe ngemicu okanye ngameva, ikhwela (Calamus) okanye ngaphantsi komhlaba (I-Nypa fruticans). Abanye banokumelana namandla enkanyamba, njengoko imithi yesundu iswele i-cambium ngenxa yoko ine-trunk eguqukayo ngakumbi. Kodwa abanakho ukuphinda bavelise izicwili zangaphandle: abanako ukuphilisa amanxeba.
• Amagqabi: inokuphoswa (Butia, Phoenix, I-Chamaedorea, njl.njl.), Ezo zinto ziphuma kumacandelo aqhelaniswe kamva; i-bipinnate (i-Caryota), ngabo abo iincwadana zabo ziphindwe kabini; ukuqhwaba izandlachamaerops, ICopernicia, iTrithrinax, njl. Njl. kunye neendleko zeendleko (uSabal, Livistona, Raphis, Licuala), engamagqabi amile okwekhephu afakelwa ipetiole ekwimo yobambo kwincakuba.
• I-inflorescence: iseti yeentyatyambo. Zikhuselwe zi bracts ezibizwa ngokuba zi spathes.
• Floreszincinci kakhulu, zenziwe ziipalali ezi-6 kwii-whorls ezi-2. Uninzi lweentlobo zine-monoecious (kunye neesampulu zamabhinqa nezamadoda), kodwa kukwakho nezo zine-dioecious. Imithi yesundu inokuthi ibe yi-monocarpic (Corypha), oko kukuthi, emva kokuba idubule yakuba ifile ishiya ngasemva inani elikhulu lembewu, okanye i-polycarpic, intyatyambo kanye ngonyaka ukusukela oko ifikelela ebudaleni.
• Iziqhamo: banokuba ngohlobo lwedrupe (iCocos) okanye idrupe (iPhoenix), kwaye banobunzima obuguquguqukayo, ukusuka kwiigram ezimbalwa ukuya kwi-25kg.
