species, and on the basis of data supplied by him, arrangments 

 were made to extend his time in Amboina until the first of June, 

 1914, thus giving him nearly a year in the field. The work he 

 actually accomplished in his four and one-half months in Amboina 

 has been of inestimable value in determining the status of the 

 numerous Rumphian species, but his collections would have been 

 far more valuable had he been spared to complete his task. 



It was no part of my plan to work this Amboina material, 

 for the final reports were to have been prepared for publication 

 by Doctor Robinson. However, owing to the unforeseen and 

 unfortunate ending of the Amboina exploration it has devolved 

 upon me to complete the work that was made possible by the 

 material and data secured by Doctor Robinson. 



The present contribution is not, and from its very nature 

 cannot be considered, more than a mere contribution to our 

 knowledge of the flora of Amboina. None of the numerous 

 species described and figured by Rumphius are included. How- 

 ever, under the circumstances associated with the untimely death 

 of Doctor Robinson, it has been deemed expedient to compile 

 an enumeration of the miscellaneous material included in his 

 collections. While the enumeration is practically complete for 

 higher plants represented in the Reliquiae Robinsonianae 

 series, this statement does not hold true for the cellular crypto- 

 gams. In the Reliquiae Robinsonianae series there are 1,142 

 numbers — nearly twice as many as in the Plantae Rumphianae 

 Amboinenses. About 217 of these are fungi; 72 are mosses; 

 54, hepatics ; and 14, algae. Owing to the unsettled conditions 

 brought about by the present war, it has not been possible to 

 include in the present paper more than an enumeration of the 

 lichens among the cellular cryptogams. The manuscript report 

 on the mosses, prepared by Doctor Brotherus, of Helsingfors, 

 Finland, has been lost or destroyed in transit ; the hepatics have 

 not been submitted to any specialist; the algae still remain 

 unidentified ; while the report on the fungi, which were placed 

 in the hands of Doctor Sydow only after many difficulties had 

 been overcome, and then only after the third attempt, has been 

 retained either for publication in Europe or for transmission 

 when conditions shall have again become normal. Likewise, in 

 the present paper, the Pteridophytes have not been included, as 

 these plants have already been enumerated by Captain C. R. W. K. 

 van Alderwerelt van Rosenburgh. 5 Reports on the Orchidaceae
