PINACEiE 143 



a blunt point, the base flattened into a short stalk. Reproductive 

 organs unknown. 



The species was discovered in the State of Sarawak, Borneo, 

 between the years 1865 and 1868. It is possibly merely a 

 geographical form of A. loranthifolia , but we have only seen 

 imperfect specimens. 



Warburg, Monsunia, I, 184, t. viii, f. 7 (1900). 



Agathis borneensis, Warburg. 



A large tree with stout branches terminated by rounded buds 

 covered by a few large, closely-pressed scales. Leaves usually 

 opposite and arranged in one plane by a basal twist of their 

 flattened stalks ; elliptic or oval, narrowing to each end, apex 

 rounded, the base flattened into a staDi |-| in. long ; the leaf- 

 blade 1|-3| in. long, i'„-l.-, in. broad, leathery, dark green above, 

 paler beneath, with well-marked longitudinal lines on each surface, 

 margins recurved. Male calkins solitary in the leaf axils, on 

 short stalks i'„-.^ in. long. Cones not seen. 



This plant was discovered by Dr. Beccari in Borneo between 

 1865 and 1868. It appears to be closely alhed to A. loranthijolia 

 and may be only a geographical variety of that species. 



Warburg, Monsunia, I, 184, t. viii, f. D. (1900). 



Agathis celebica, Warburg.^ 



A tree 120-160 ft. high, with a clean cylindrical trunk of half 

 that height, indistinctly buttressed at the base. Leaves about 

 3 in. long by 1 in. broad. Male catkins lf-2 in. long, |-J in. wide. 

 Cone, 3-3| in. long and about 2j in. wide. Seed oblong with a 

 broad, flat wing. 



This species is a native of the Celebes, and as a good deal of 

 fossil resin is said to be found in the Celebes it is presumably 

 derived from past generations of this tree. 



Agathis flavescens, Ridley. 



A tree 40 or more ft. high with a trunk 3 ft. in girth at 

 the base. Young shoots yellowish. Leaves elliptical or obtuse, 

 narrowing to the base, thick, leathery, yellowish-green, 2-2| in. 

 long, about |-1 in. wide. Male catkins about 1-1 -|- in. long, ^ in. 

 wide. Cones globose, 2| in. long, 1| in. wide ; scales, 1^ in. long, 

 1 in. wide. Seeds elliptical. 



This species is closely alhed to A. regia, from which it differs 

 in its smaller male catkins. Ridley says that it is quite distinct 

 from A. loranthifolia, Sahsb. 



Native of the Malay Peninsula and collected by Ridley on 

 the Padang of Gunong Tahan, at an altitude of 5,000 ft. On 



^Monsunia, 185 (1900).
