ETYM Latin, a kind of cactus, Greek.
Plant of the family Cactaceae, although the term is commonly applied to many different succulent and prickly plants.

They all have special adaptations to growing in dry areas.
Cactus flowers are often large and brightly colored; the fruit is fleshy and often edible, as in the case of the prickly pear. The Cactaceae are a New World family and include the treelike saguaro and the night-blooming cereus with blossoms cm/in across.
(Irregular plural: cacti or cactuses).
Any spiny succulent plant of the family Cactaceae native chiefly to arid regions of the New World.

kaktus [ muški rod {botanika} ]

Južnoamerička zelena i mesnata bodljikava biljka.
Donedavno se verovalo da bodlje kaktusa imaju isključivo ulogu zaštitnika od životinja i ptica koje se u slobodnoj prirodi hrane ovim bodljikavim biljkama. Takođe se pretpostavljalo da ove čvrste izrasline smanjuju velika isparenja u oblastima sa žarkom klimom.
Ustanovljeno je međutim, da bodlje odlično upijaju i najmanju količinu vode iz gotovo potpuno suve atmosfere. Nemačkim naučnicima je pošlo za rukom da uz pomoć radioaktivno ozračenih atoma dokažu da u vazduhu zasićenom vodenom parom bodlje kaktusa mogu da preuzmu ulogu korena u snabdevanju biljaka vodom. (grč.)
