THE AMBOINA PTERIDOPHYTA COLLECTED 

 BY C. B. ROBINSON x 



By C. R. W. K. van Alderwerelt van Rosenburgh 

 (Buitenzorg, Java) 



The present paper consists of an enumeration of the Pterido- 

 phyta collected by the late Dr. C. B. Robinson in Amboina. The 

 object of his field work there was to collect a series of specimens 

 that should represent the forms actually described by Rumphius 

 in the Herbarium Amboinense, so far as such material can 

 definitely be connected with the Rumphian descriptions. 



The definite or suggested identifications with the Rumphian 

 species cited in this paper, are for the most part those made 

 by Doctor Robinson during the prosecution of his field work in 

 Amboina, July 15, 1913, the date of his arrival there, to December 

 5, 1913, the date of his untimely death. The entire collection 

 was divided into two series: First, those that can definitely or 

 fairly definitely be referred to species figured and described, 

 or merely described, by Rumphius ; and, second, those that were 

 apparently unknown to Rumphius, or at least that were not 

 described or figured by him. The former are to be distributed 

 with special labels, Plantae Rhumphianae Amboinenses, with 



1 The present paper is the first publication to be issued on the results 

 of the field work of the late Dr. C. B. Robinson in Amboina. Work on the 

 remainder of the collection is being prosecuted as rapidly as possible and 

 it is hoped that the whole can be prepared and issued at no distant date. 

 The complete publication, as being prepared, will consist of a critical con- 

 sideration of the Rumphian species so far as their status can be determined, 

 worked out not from a study of literature alone like the interpretations 

 of Burmann, Stickman, Linnaeus, Henschel, and, to a large degree, Hass- 

 karl, but from a study of the literature supplemented by the fairly 

 comprehensive Amboina collections now available through the active field 

 work of Doctor Robinson. 



In view of the special plan on which this proposed work is being pre- 

 pared, it has been considered best to publish the present paper without 

 delay and in its present form. [E. D. M.]
