40 INTRODUCTORY ESSAY. 
XXV.—-Note on Rumph’s species of Calamus and Daemonorops, 
Subjoined is a conspectus of the species of Calamus and Daemonorops figured 
in the fifth volume of Rumph’s Herbarium Amboinense.

58-2. Rotang Assam = Calamus acidulus Bece. 
The Rotang Assam his been referred by Blume to C. barbatus, but to me 
it appears to be quite distinct nct only from this species, but from any other 
hitherto known. The species distinguished by an asterisk (*) have been definitely 
recognised. The others represent, I believe, very well-marked species which will be 
recognised at some future time because, considering the period at which they were 
made, Rumph’s figures are very good and the descriptions, if properly understood, 
are quite reliable. I have therefore no doubt that these species will be found again 
in the Moluccas when these islands are better explored. 
This belief cannot be certainly entertained regarding the species which are 
incidentally mentioned or imperfectly described by Rumph. These are as follows:— 
Calamus Buroensis Mart.; C. viminalis var. repens Bl.; C. graminosus Bl.; C. maritimus Bl. 
For information regarding these, reference should be made to the detailed 
account of them given in the section that deals with doubtful species. 
XXVI.—Note on the date of publication of the species of Calamus and 
Daemonorops named by Martius, Griffith and Blume. 
The fact that Martius, Griffith and Blume were at work contemporaneously 
on the genera Calamus and Daemonorops has led to great confusion in the synonymy 
of these genera. 
The great work of Martius, ‘‘ Historia Naturalis Palmarum," and the “ Rumphia ” 
of Blume were published in parts at long intervals, and I have not been able in 
all cases to ascertain the precise date of publication of each part. Moreover, some 
of the pages of the third volume of the “Historia Naturalis Palmarum," those num- 
bered 179 fo 230, were originally printed on paper of a different colour from the 
rest, These pages were, affer an interval of many years, reprinted and the reprint 
substituted for the original. But the reprint of these pages was in reality a new 
edition— very different from the original, for the author took advantage of their 
publication to entirely change the text and to make numerous additions. 
In the first edition of these pages (179—230) the generic characters of Calamus 
are given at page 203, and in the pages that follow six species of this genus, of 
t With reference to this subject, the note by Martius himself in the Errata at the end of vol, iii may be consulted,
