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.
