annular disk. Anthers, attached to the apices of the filaments, 

 broadly ovate, sparsely pubescent. Ovary pubescent, conical, 

 surrounded by the disk. Style short, stigma globular. Fruit 

 globular, about 1 cm in diameter. 



Luzon, Prov. Camarines Sur, Pasacao (Ahern no. 108 and 

 no. 264). 



The species above described is recorded in Bulletin no. 1. 

 Porestry Bureau, Department of the Interior p. 29 (1903) under 

 the name of Walsura robusta Roxb. I find, however, that the 

 flowers and the calyx are much larger in Roxburgh's specimen, 

 and that, moreover, in his plant the filaments are flattened and 

 lanceolate and are free from each other, while, in my specimen, 

 they are united into a tube in the lower half. Moreover, the 

 disk of Walsura robusta is pubescent and subconcave, that of 

 this plant is glabrous and annular. 



The collector Merrill, who has given an enumeration of 

 Ahern's plants, was himself doubtful of this identification.

Pinus Linn. 



1. Pinus insularis Engl. 



Luzon, Prov. Benguet (Merrill no. 1160, 1161, 1162, 1163, 

 1164, 1165; January 1903). 



2. Pinus insularis x Merkusii. 



Luzon, Prov. Zambales, Subig and vicinity (Merrill no. 2116; 

 April 1903). 



3. Pinus Merkusii Jungh. 



Luzon, Prov. Zambales (Merrill no. 1158; January 1903). 



As there was no material of this species for comparison 

 in the Berlin herbarium, I have accepted the determination 

 of Merrill.
