Re: [Aroid-l]Off-topic-- Rafflesia/host vine

From: "Alistair Hay" <ajmhay at hotmail.com> on 2007.01.19 at 05:37:23(15103) 6 or 7 species of Tetrastigma are hosts to Rafflesia spp. but the principal one is T. leucostaphylum. There does not seem to be a one to one relationship between Raff species and host species. Jamili Nais (who wrote the book) reported that they has successfully inoculated 2cm diam and 4 cm diam Tetrastigma vines with Rafflesia seeds: success indicated by flowering about 4 years later.
