several times been visited by botanists; and buds and flowers 
have repeatedly been carried away from here. I found 10 buds 
of different sizes and 2 fruits. 
e. Some 1100 M. above sealevel. Upon the sheer slope of the 
just mentioned old volcano consisting of massive andesite rocks, 
about 60 M. inside and above the edge of the forest, along 
which a small creek runs, feeding extensive rice fields. Already 
known and visited by some few Europeans. I found here 6 buds 
(4 to 26 cM. across). 
f. About 500 M. above sealevel in high forest on sloping hill 
side (tuff) nearly 40 M. above a little creek. Native plantations 
are established in the neighbourhood. The place is lonely and 
not often visited by natives. The people of the nearest village 
(some few houses c. 400 M. away) did not known anything 
about the Rajlesia and its presence in the region. Four buds 
only were found (1 to 12,5 ctm. across). 
Those are the 6 places, in which, during a tour of 6 months, 
[ have established the presence of Rafflesia. On numerous excur- 
sions through wide areas and all sorts of country I everywhere 
searched for the plant, and always sought information about it 
from the natives, but I failed to find anything more. Why then, 
did it grow on those few spots? What was the common factor, 
that made them specially fit for this distinction? Certainly it 
was not the presence of the vine alone, as vines are growing 
abundantly everywhere in the forests and amongst them probably 
very many of the sort, on which we so very exceptionally find 
the parasite. 
None of the spots were situated in the depth of the forest 
all were found very near the forest edge and not far from 
cultivated and inhabited or at least more or less frequently 
visited places. It thus looks likely, that the growth of the 
Raflesia, or the spreading of it, is facilitated by some factor 
present in the area connecting the wild forest with the open 
or cultivated country. : 
This impression has been emphasized by a communication, I 
have received from Mr. Epw. Jacosson, who has kindly told me 
about the Rafflesia places, known to him. They are: 1) the well-
