-Besides the Australian species, which is endemic, the gemis eoniprisos three others, natives 

 01 the narmer rcglous of Asia, one of them much planted in various parts of the globe, 



^ 1. A, imberbiflora, F. MitelL Fragm. iii, 42. A tree, quite glabrous 



in all its parts. Leaflets about 15 to 17, shortly petioluiate, apparently 

 obliquely ovate-lanceolate and 2 or 3 in. long, but nuich broken in the only 

 specimens seen. Panicles not much branched. Mule flowers on short pedi- 

 eels, in little clusters along the upper part of the branches. Calyx very smalL 

 ■Petals about IJ^ lines long, quite glabrous, valvate, not induplicate, and the 

 pomts scarcely inflcxed. Stamens cxscrted. Female flowers not seen. Sa- 

 Eiaro} ill our specimens attaining at least 2 in. in length and \ in. iu breadth. 



Queensland. Roekhamptou, Thozet, Evidently, as suggested bj E. Mueller, very 

 pcaHj allied to the E. Indian A. maJahanca, DC. Prod. ii. 80, Wight, Ic. t. 1G04, which 

 indeed seems only to differ in a slight pubescence oa the panicle and in rather larger tlowers 

 and fruits. ^ 



^. rhodoptem, P. Mucll. Fnigm. iii. 43, -mentioned as cultivated in New England, is the 

 commonly planted A. glandiilosa, Desf., DC. Prod. ii. 89. A. punctata, F. Muell. 1. c., is 

 ^entaceras australis. Hook, f., of which the fruit closely resembles that of an A'dant/ius in 

 outward form, althou)<h the inner structure as well as the flower are very ailTereut, 



• 3. BRUCEA, Mill. 



Flowers polygamous. Calyx small, 4-cleft. Petals 4, minute, linear, im- 

 l>ricate in the bud. Disk 4-lobed. Stamens 4. Ovary 4-lobcd or of 4 dis- 

 tnict carpels, the styles free or connate at the base, the stigmas entire, spread-

 tamen nigose. Seed with a membranous testa ; albumen copious ; einbryo 

 straight, radicle superior. — Trees. Leaves alternate, pinnate ; leaflets oblique. 

 Piowers very small, iu small cymes, in simple slender axillary spikes. 



. The genus corwprises a veiy few species, spread over tropical Asia and .\frica, csteuiliug 

 into northciu ludia. The Australian species is one of the commonest Asiatic ones.
