VII PREFACE. 
showed themselves in various ways in portions of the manuscript. 
The literal reading of the text has been scrupulously adhered 
to, except in certain minor points where I felt justified in using 
an editorial discretion, and in certain other cases where, mainly 
owing to ambiguity of expression, changes seemed imperatively 
demanded. Where these were of a nature to require the advice 
of a professional botanist they have been made only after 
meeting with the full approval of Professor Askenasy, to whose 
vigilance, infact, the chief corrections of this character are due. 
It is believed that every error of consequence overlooked in 
the proof has been noted in the list of Corrections and Additions. 
That these errors are so numerous as they appear arises in part 
from the fact that only one proof could be examined by mysell, 
in part from certain inconsistencies in the manuscript which 
were not apparent in correcting the proof-sheets as they arrived 
from time to time. | 
The present work comprises descriptions of all indigenous 
and well naturalized Phanerogams and Vascular Cryptogams 
known to have been collected on the Hawaiian Islands*. Among 
them are 180 species and 6 genera which are considered new. 
The author had also made considerable collections of mosses, 
lichens, ete., and it is probable that these may be entrusted for 
examination to some authority upon the subject, in which case 
the results will doubtless be given to the world at some future 
time. 
In giving the habitat of a plant the name of the island is 
printed in spaced letters, that of a district or place in italics. 
The sign 7 appearing before a specific name indicates that 
the species is of recent introduction into the Hawaiian Islands, 
i. e., since the discovery of the group by Capt. Cook. The 
conventional sign! placed after a name denoting habitat signifies 
that a specimen or specimens of the species described are to be 
* Including those reported by other botanists and not observed by the socal 
Only in eases where the assignment of a species to the Hawaiian Islands was kno 
by him to be founded on error has such species been omitted
