THE AMBOINA PTERIDOPHYTA COLLECTED 
BY C. B. ROBINSON 1 
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.]
