It will be observed that I have not included G. welborni 
Elmer, from Negros, because I see no difference between it and 
G. luzonica, nor G. fragrans Mere., which Mr. Merrill has al- 
ready reduced to the same species. 2 
Gordonia luzonica in the Manila herbarium is represented 
from Mount Mariveles, Bataan Province, by the following speci- 
mens: Merrill 3732, Whitford 305, For. Bur. 809 Borden, Wil- 
liams 747, For. Bur. 236 Meyer, and For. Bur. 6229 Curran, 
collected at varying heights between 600 and 1,500 meters 
above sea level. The trees are recorded as from 6 to 20 meters 
high with a diameter at breast height of 30 to 100 cm. Meyer 
states that it is very common. Evidently it occurs as isolated 
individuals upon ridges and exposed slopes. Just north of 
Bataan, in Zambales Province, Ramos collected it as a rather 
small tree at Tapotas, Bur. Sci. 5091 Ramos. In Laguna Prov- 
ince it occurs at Paete, Bur. Sci. 5077 McGregor and Bur. Sci. 
10029 Ramos; at Papatakem, Merrill Phil. PI. 428, coll. Ramos, 
and on Mount Banahao, Bur. Sci. 27939 Ocampo. The recorded 
altitudes vary from 100 to 1,376 meters. The height recorded 
for the trees is from 28 to 30 meters with a diameter at breast 
height up to 117 cm. It was also collected on Mount Banahao 
by Vidal, the altitude given as 600 to 1,000 meters. The Cuer- 
nos Mountains where Mr. Elmer secured his G. welborni, Elmer 
9584, are in the southern part of Negros; Mount Silay where 
Mr. Whitford has gathered the species (No. 1499) is in the 
northern part of the same island. The altitude on Mount Silay 
is recorded as 1,044 to 1,135 meters; that on the Cuernos Moun- 
tains as 1,300 meters. Mr. Elmer records trees as reaching the 
height of 50 meters, or 160 feet. The statement that this 
species occurs in Mindanao rests upon fallen corollas only, and 
therefore is not to be reckoned as well founded. These fallen 
corollas were picked up by Mrs. Clemens at Camp Keithley on 
Lake Lanao. 
The flowering period of G. luzonica must be as extended as is 
that of the Singapore gordonias. On Mount Mariveles flowers 
have been secured in January, February, and March; in Laguna 
Province, in May, July, and August; in Negros, in May and 
June; and in Mindanao, in July. The flowers are white and 
fragrant.
