xi, c, 5 Merrill: Reliquiae Robinsonianae 249 
The present paper, as noted above, is based on the material 
that cannot definitely be referred to any of the forms figured or 
described by Rumphius. The most important results of the 
work of Doctor Robinson in Amboina are to be included in the 
general report on the species of the Herbarium Amboinense, to 
be issued in the near future under the title : “An Interpretation 
of the Herbarium Amboinense.” 
In closing this introductory statement I would call attention 
to the fact that through the interest of Doctor J. C. Konings- 
berger, director of the Botanical Garden, Buitenzorg, Java, Doc- 
tor Robinson’s work in Amboina was greatly facilitated by the 
detail of a native assistant from Buitenzorg, the mantri Mard- 
joeki, to aid him in the collection and preparation of material. 
The work done by Doctor Robinson in Amboina was in a way 
cooperative between the Bureau of Science on the one hand, and 
the Botanical Garden at Buitenzorg, Java, on the other. It is 
hope that the work accomplished will be to the mutual benefit 
of both institutions, as well to botanists and other botanical 
institutions in the world at large. 
ENUMERATION OF THE SPECIES 
ALGAE 
This group is rather poorly represented in Doctor Robinson’s Amboina 
collection, 14 numbers being included in the series Reliquiae Robinsoniayiae, 
all, or nearly all, marine forms. No report on this material is available for 
publication. 
FUNGI 
There are about 217 numbers of fungi included in the series Reliquiae 
Robinsonianae, for the most part minute parasitic forms. This material 
has been placed in the hands of Doctor Sydow for study, but owing to the 
exigencies of the present European war, no report is available for publi- 
cation at this time.
