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 Robinsonianae, 

 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.
