Introduction
The annual Byblis species (Byblidaceae, Lamiales) are predominantly Australian endemics with B. liniflora
extending also north to Papua New Guinea (Cross et al. 2018). Beside
their features as sticky carnivorous plants, many enthusiasts
especially appreciate their bushy appearance with many showy
hermaphroditic flowers. The following report features our experiences
with the cultivation and hybridization of B. filifolia and B. liniflora over two decades at our heated greenhouse in Weil am Rhein (Germany).
Deutsche Übersetzung:
Die einjährigen Byblisarten (Byblidaceae, Lamiales) sind
hauptsächlich australische Endemiten, bis auf B. liniflora, die auch
weiter nördlich bis Papua Neuguinea vorkommen (Cross et al. 2018). Neben
ihren Eigenschaften als klebrige Karnivoren, sind sie bei vielen
Sammlern wegen ihrer buschigen Erscheinung mit zahlreichen prächtigen
zwittrigen Blüten beliebt. Der folgende Artikel zeigt unsere Erfahrungen
mit der Kultur in unserem beheizten Gewächshaus in Weil am Rhein sowie mit die Hybridisierung von B. filifolia und B. liniflora.

We produced a documentary film for YouTube, to accompany the article regarding the trichome motion..
