“ Of the approximately 375,000 species of plants known to man, no other plant has succeeded in creating so much botanical interest as has Welwitschia; nor has any other plant so defied man’s habit of categorizing, ” writes Chris Bornman in his book Welwitschia ​ — Paradox of a Parched Paradise.
„ Mitte ükski teine inimesele teadaolevast 357 000 taimeliigist pole tekitanud nii palju botaanilist huvi kui velvitšia ega põhjustanud nii suurt peamurdmist klassifitseerimisega, ” kirjutab Chris Bornman oma raamatus „Welwitschia – Paradox of a Parched Paradise ”.
