This article is devoted to 'Kvetomluva', the only work of fiction by Karel Slavoj Amerling, which includes his adaptations of regional tales connected with the 'language of flowers'. Analysing its text we try to show that its author intends to reach more aims at the same time and the result of his effort is interesting and sometimes even unintentionally comic heterogeneity of his text. Amerling's 'Kvetomluva' interfaces not only between cultural peripheral communication code of the 'language of flowers' and an attempt at high literature but also between belles-lettres and scientific literature. This syncretism (Vladimir Macura's term) fits in the synthetic character of the culture of the Czech national movement in general. However, we try to document that the main goal of 'Kvetomluva' was in our opinion presenting the complete system of the ancient Slavic mythology as the background of the stories of the book. In accordance with the romantic approach to folklore this mythology was presented as a reconstruction based on regional tales, which were considered to be relicts of the old myths, but in fact it is purely constructed to fulfil the wishful thinking about the old Slavic myths as an evidence of the glory of the Czech nation.
