DESCRIBED IN BLANCO'S "FLORA 



DE FILIPINAS."

In April, 1905, I published a work entitled "A Review of the Identi- 

 fications of the Species Described in Blanco's Flora de Filipinas"^ 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 F crnandoz-V illar , 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 previoush^ accepted by me. 



Through the kindness of Dr. C. B. Robinson, of the ^STew 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 Linna'a 

 (1842), vol. 16, Litteratur-Bericht, pages 1 to 68, in which the first
