XXXVI—A REVIEW OF THE KNOWN PHILIPPINE 
ISLANDS SPECIES OF IMPATIENS. 
J. D. Hooker. 
The materials on which the following attempt to classify the known 
Philippine species of Impatiens is founded are the following :— 
1, the published account of J. Balsamina in Blanco’s Flora de 
Filipinas (1837) under the name of J. triflora, Blanco ; 
2, the type specimen of I. manillensis, Walp. (1848), loaned to 
me by the good offices of the Keeper of the Royal 
Herbarium of Berlin ; 
3, three species presented to the Kew Herbarium by Mr. 
Sebastian Vidal ; 
4, ten species collected by Mr. A. Loher, a resident in Manila, 
and presented by him to Kew ; 
5, a few species in the Herbarium of the Botanic Garden, New 
York, kindly loaned ; 
6, herbaria made by various collectors (including Mr. Loher) 
subsequent to the occupation of the islands by the Govern- 
ment of the United States, brought together by Mr. Elmer 
D. Merrill* and kindly loaned to me for description, together 
with duplicate specimens of many presented to t w 
Herbarium. In this last collection the specimens are for the 
most part carefully numbered and ticketed as to locality and 
collector’s name ; they do not together form part cf a single 
Government Herbarium, but belong to various Government 
departments. It hence appears necessary when citing a 
number to add the name of the Herbarium in which the 
corresponding species is to be found. The Herbaria are 
designated as follows :— 
erbarium of the Bureau of Science. 
Government Laboratories. 
9 », Exploration of the Philippines. 
Philippine Exposition Board. 
Philippine Normal School. 
San Fernando Provincial High School. 
* Mr. Merrill is author of many papers on the Flora of the Philippine 
Islands, of which thirty-one, dating from 1903, are recorded in the library of 
the Herbarium of the Royal Botanic Gardens.
