A. rhomboidalis Warb., the Malay Peninsula. 



A. beccarii Warb., Borneo. 



A. borneensis Warb., Borneo. 



A. philippinends Warb., the Philippines. 



A. celebica (Koord.) Warb., Celebes. 



A. motleyi (Pari.) Warb., Borneo. (Since credited to Podocarpus.) 



Differences in size and shape of leaves, size of staminate and pistillate 

 cones, and appearance of the resin are made the basis of this division. 

 After comparison of fresh and dried material of A. pliilippinensis, A. 

 beccarii, A. borneensis, and a study of material of A. celebica kindly 

 loaned me by Dr. Treub, I am convinced that these four species at any 

 rate should not be separated from the original A. alba. The tree is a 

 very large one and material taken from different parts of the same 

 individual shows a wide range of variation. A single Philippine tree 

 will yield material to fit the descriptions of A. dammara, A. pliilip- 

 pinensis, A. celebica, A. beccarii, and A. borneensis, as given by Warburg. 

 I have studied the Philippine and Bornean trees in the field and they 

 are identical in habit. Doctor Beccari 10 also considered A. beccarii and 

 A. borneensis merely varieties of A. alba. 



Described differences in the appearance of the resin may be due to the 

 different seasons of collection, or to the different age of the samples 

 collected. While by no means prepared to say what is the status of 

 the genus in other parts of Malaya, I can see no reason for supposing 

 that there is more than one species in the Philippines, or that it is 

 other than Agathis alba. 



This is closely related to the Kauri, Agathis robusta (Moore) Warb., 

 of Australia and New Zealand. Other species of the genus are found 

 in Few Caledonia and Fiji. 



The almaciga is a very large tree, growing to a height of from 50 to 

 60 meters and, to a diameter, breast high, of more than 2 meters, with a 

 clear length of 30 meters or more. The bark is rather smooth and of a 

 grayish color. It is a centimeter or more in thickness and contains 

 numerous longitudinal resin canals. The tree has an altitudinal range 

 of from 150 to 2,000 meters above sea level, attaining its best develop- 

 ment in the Philippines on well-drained slopes at 600 to 1,500 meters 

 above sea level. It is known in the Philippines by the following- 

 names: Almaciga (Spanish) ; biayo, bidyangao (Visayan) ; bunsog, litao 

 (Igorot) ; diilur (Bagobo) ; galagala (Tagalog) ; ladiangao (Bicol) ; 

 macao ( Moro ); saleng, uli (Negrito). 



The distribution in the Philippines is as follows: Island of Luzon, Provinces 

 of Cagayan, Lepanto, Benguet, Zambales, Bataan, Camarines, Sorsogon, Albay. 

 It is abundant on the Islands of Mindoro, Negros, Palawan, Sibuyan, and Min- 

 danao, on which last-named island it is known from Misamis, Davao, and Zam-
