Re: [Aroid-l]Off-topic-- I did sow Rafflesia

Dear all,
I read all the messages concerning Rafflesia and I can tell you that in the time that I had the position of Curator of the Botanical Garden of Amsterdam I received seeds of Rafflesia gadutensis from Willem Meyer (they expert on Rafflesia's) in 1991. The seeds were collected by a amateur plant collector in Ulu gadut (West Sumatra) and offered to the Missouri Bot. garden. The host plant for Rafflesia was indeed Tetrastigma leucostaphyllum. The seeds were sown just under the bark of the host close to the soil, or close to the roots scraped off a bit. the placed of inoculation were marked with labels and accurate record was kept by me. Willem Meyer told me that in case of succes within 1-2 years flowering buds of Rafflesia may appear, but unfortunely we used a to young plant of Tetrastigma leucostaphyllum so the seeds didn't germinate. There is only one record of a succesfull inoculation and that's in Bogor.

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.
