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 Merr., 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 

 958k, 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.
