the Leptospermoideae, also represented in South America by the 

 Chilean genus Tepualia. This will be made clear by the following 

 amended and completed description : 



AULACOCARPUS Berg. 



Receptacle forming a crater-like cup above the ovary. Sepals 5, 

 short, obtuse or acute. Petals 5, unguiculate, apiculate. Stamens 

 10, mserted on the margin of the receptacle, 5 opposite to, 5 alternate 

 with the sepals, curved outward beyond the corolla, the basifixed 

 2-celled anthers hanging around the receptacle ; anther cells longitu- 

 dinally dehiscent. Ovary 5-celled, each cell with 5 (or 4) ovules; 

 style simple, truncate. Drupe depressed-globose, horny or sublignose, 

 5 to i-celled, each cell with I seed. Seed albuminose, covered with a 

 thick, suberose testa. Cotyledons plano-convex, thick ; radicle basal, 

 very short. Trees with very hard wood ; leaves opposite, exstipulate, 

 thick, obscurely veined ; flowers single or few in a cluster, pseudo- 

 axillar3^ 



Species 5, Tropical American. 



On account of its fundamental characters, viz. : exalbuminose seed, 

 short basal radicle, ovate-depressed seeds, indehiscent woody drupe, 

 5-celled ovary, and 10 stamens, with basifixed anthers, Aulacocarpus 

 would take perhaps an intermediary position between the Calotham- 

 ninae and the Chamaelauciae. The genus does not naturally fit into 

 any of the present divisions of the Leptospermoideae, although there 

 can be no doubt as to its belonging to this subfamily. 



The collection and study of new materials of the 4 species of 

 Aulacocarpus already described is highly desirable and it is not un- 

 likely that a better knowledge of the genus will result in a reduction 

 of the number of species. My own specimens do not agree with any 

 existing description, and so 1 have presumed to describe them under 

 a new name. 



AULACOCARPUS COMPLETENS, sp. nov. 



A tree up to about 18 meters high and 35 to 40 cm. in diameter at 

 the base. Crown elongate ; trunk continuous. Bark smooth, grayish. 

 Entirely glabrous. 



Leaves opposite, large, coriaceous, short-petiolate. Stipules none. 

 Petioles thick. 4 to 5 mm. long. Leaf blades 14 to 25 cm. long, 5 to 

 II cm. broad, ovate-elliptic (broader toward the base), cordate to
