ADDITIONAL IDENTIFICATIONS OF THE SPECIES 
DESCRIBED IN BLANCO’S “FLORA 
DE FIL1PIN AS.”

In April, 1905, I published a work entitled “A Review of the Identi- 
fications of the Species Described in Blanco’s Flora de Filipinas” 1 in 
which an attempt was made to correlate the species considered by Blanco 
in the different editions of his “Flora de Filipinas,” and to summarize 
what was known regarding them, indicating those that were referable 
to known and previously described 'species, those that were apparently valid 
and those that were unknown or doubtful. Since the publication of 
that paper, one of the objects of which was to serve as a guide in the 
collection of material and data that might serve to clear up doubtful 
points in Blanco’s work, extensive collections- have been made and our 
knowledge of the Philippine flora has been greatly extended, while from 
time to time certain points regarding Blanco’s work have been cleared 
up. Accordingly it is proposed occasionally to publish notes regarding 
Blanco’s species, as the data available seems to warrant such action. 
■ In the preparation of the previous work too much dependence was 
placed on the work of Fernandez-Villar, and his identifications of some 
of Blanco’s species were then accepted which have since been found to 
have been erroneous. Doubtless in the future as various groups are 
carefully monographed, numerous changes will have to be made in his 
identifications that were previously accepted by me. 
Through the kindness of Dr. C. B. Robinson , of the New York 
Botanical Garden, I have received copies of two papers in which references 
are made to previous attempts at clearing up Blanco’s species, which 
seem to have been overlooked by most, if not all, recent investigators of 
Philippine botany. The first paper is that of Walpers, a summary of 
the first edition of Blanco’s “Flora de Filipinas” published in Linncea 
(1842), vol. 16 , Litteratur-Bericht, pages 1 to 68, in which the first
